VOLUME XXIX. A CONTRIBUTION TO THE KNOWLEDGE OF THE ORTHOPTERA OF MEXICO AND CENTRAL AMERICA. BY JAMES A. G. REHN. This paper contains the results of a study of 464 specimens, princi- pally from the collection of the author (now presented to the Academy of Natural Sciences of Philadelphia >, beside a small quantity of ma- terial in the collection of the Academy, and an interesting series of 118 specimens belonging to the United States National Museum, loaned through the kindness of Mr. W. H. Ashmead of that insti- tution. The specimens from the United States National Museum are designated by the initials of that institution, while those from the author's collection are unmarked. The original intention of the author was to make this paper a faunistic study, but many new species and records forced themselves into view, and the conclusion was reached that the present time is too premature for such studies in the region under consideration.

TRANS. AM. ENT. SOC, XXIX. NOVEMBER. 1902. 4 JAMES A. G. REHN. This species is closely related to both E. conspersa and azteca, but is separated from each by very appreciable characters. The size is less than E. conspersa, the apex of the anal field is acute instead of obtuse as in that species, and the supranal and subgenital plates are both more acuminate. From E. azteca it is separated by the form of the supranal plate, which is produced and acuminate instead of rotundate or subtruncate. Size rather small. Head distinctly visible in front of the pronotum when dorsally viewed, anterior outline well rounded ; eyes large, considerably sepa- rated ; antennae filiform, sparsely pilose, over twice as long as the pronotum. Pronotum large, produced anteriorly, posterior margin triangularly produced, deflected lobes with the margins broadly rounded. Tegmina exceeding the apex of the abdomen, rather narrow, apex rounded, costal margin gently arcuate; anal sulci extended posteriorly, giving the anal field a semi-hastate form. Wings ample, extending to the tip of the tegmina when in repose. Femora sparsely spined ; an- terior paii- bearing four spines on the central portion of the lower margin, three moderately large spines on the upper margin ; median pair bear three centrally grouped spines on the lower margin, four on the upper; posterior pair with three spines on each margin, those on the lower margin centrally grouped, the last spine on the upper margin separated from the other two by a considerable inter- space. Tibiae heavily spined ; basal tarsal joint set with fine spines, the general appearance being that of pectination. Supranal plate triangularly produced, margins somewhat reflexed, apex triangularly emarginate. Subgenital plate triangularly produced, scoop-like. Cerci slightly exceeding the supranal plate in length. General color above tawny-olive.* Pronotum raw umber, very closely and minutely punctate with brownish black, the punctations being largest on the periphery. Tegmina regularly punctate with Vandyke brown, the punctations largest in the anal field and in the distal half of the tegmina, which latter region contains several larger blotches of the same tint. Wings pellucid, the costal region slightly suffused with brownish and punctate with pale brownish. Both aspects of the abdomen blackish brown finely stippled on a brown-gray ground, the body tint being most noticeable below. Limbs horn, speckled with blackish brown; the overlying tint being strongest and more suffusing on the distal por- tions of the tibiae. Measurements: Length of body 21. mm.

These damaged specimens will hardly agree with any of the de- scribed species, though possibly they are L. tolteca Saussure and Zehntner (Biol. Cent.-Amer., Orth., i, p. 113).

Sciences, Philadelphia). These specimens are somewhat doubtfully referred to this very variable species. One possesses no spines on the lower margin of the femora, which fact would place it in another section of the genus, but Saussure and Zehntner inform us that these are obsolete in some individuals. The maculation of the pronotum is very vari- able in form and intensity ; in two specimens it is rounded posteriorly, entirely free from the posterior margin of the pronotum, and with the antero lateral angles much produced, the third specimen has the pos- terior margin of the pronotum forming the posterior boundary of the maculation.

Apparently closest allied to S. mezicana* Saussure, but differing in the spiniform interocular processes, and in the absence of any dorsal foliaceous lobe on the fifth abdomen segment. With the other species of the genus — saussurii, azteea and strigata — no com- parison is necessary, the general characters of the head being shared by mexicana alone. General build moderately robust, the entire body tuberculate, the tubercles most numerous anteriorly. Head with six longitudinal rows of tubercles, the median pair strongest developed, the second tubercle in each row being spini- form, several spines forming an additional group between the median rows; antennae about half as long as the body, the basal joint considerably flattened. Prothorax about as long as broad, the collar slightly constricted ; mesothorax elongate, over four times as long as the prothorax ; metathorax considerably shorter than the mesothorax, heavy, showing traces of a median carination which also extends over the median segment and on the abdomen ; median segment very short, over twice as broad as long. Abdomen moderately elongate, the tubercles arranged in four longitudinal rows on the dorsal surface, the lateral aspect with two longitudinal roughened carinas; fifth segment somewhat inflated, no foliaceous lobe developed from the medio-dorsal portion of the segment, the lateral angles being posteriorly produced into rounded posteriorly projecting lobes. Femora and tibia; multicarinate ; anterior and posterior tibiae slightly exceeding the femora in length.

The color dif- ferences as given by Thomas appear to be of no value, while struc tural differentiations are absent. The median carina of the pronotum is cut thrice in some specimens, in others twice, while a few have a very faint trace of the third incision.

AMERICAN ORTHOPTERA. 17 PRISTOCEUTHOPHILUS n. gen. Allied to Hadencecus, Ceuthophilus and Hemiudeopsylla, but pre- senting quite distinctive characters. It differs from all in the pos- session of but three pairs of spurs on the posterior tibia?, and in having a conoid development of the vertex. From Hadencecus it is separated by the elongate last palpal joint, and by the broadly emarginate subgenital plate of the male. From Ceuthophilus it differs in the nou spinous median coxae, and in the very long first hind tarsal joint. From Hemiudeopsylla difference is noticed in the absence of spines on the lower external margin of the median femora, in the absence of serrations on the lower external margin of the posterior femora, and in the presence of five or more small spines between the larger spines on the upper margins of the poste- rior tibise. Vertex produced into a deflected spinous process, extending almost as far downward as the lower border of the eyes. Last palpal joint almost twice as long as its antecedent. Anterior femora without spines. Median coxa? not spined ; femora smooth, except for the spine on the apex of the external portion ; tibia? bearing several closely appressed spines situated around the cen- tral section. Posterior femora bullate, the lower external margin non serrate, carrying one (or two) small spines on the apical half; tibia? bearing many (five to thirteen) small spines between the larger ones; apical spurs three in number; first tarsal joint very long, much longer than the remaining portion. Subgenital plate broadly emarginate. I'ristoceuthopliiliis rlioatlsi n. sp. Type: male; Uruapan, Michoacan, Mexico. April 11, 1899. Collected by S. N. and M. C. Rhoads. Size small.

In the summer of 1901 I determined to go to the Rocky Mountain? on a collecting expedition and vacation, and was influenced to select Beulah, New Mexico, from the fact that Prof. T. D. A. Cockered had taken Argynnis nitocris there. The country was represented to me as interesting from a scenic standpoint and also a good place entomologically. Beulah is situated in Sapello canon in the main range of the Rocky Mountains, about thirty miles north-west of Las Vegas in San Miguel County, New Mexico. The elevation of Beulah Post Office (Bark- er's ranch) is about 7,250 feet. My headquarters was at Blake's ranch, 8,000 feet elevation. The fauna and flora here are those of the Canadian zone. The Sapello river runs through the canon and at Beulah is a small but swiftly running creek. I arrived on the morning of August, the 9th, and left on August, the 26th, thus having sixteen days collecting. Rain fell every day but one during my stay. The thunder storms of the rainy season usually commenced in the afternoon, and unfortunately left every- thing wet for some time on the mornings following. It was gener- ally ten A.. M before the vegetation was dry enough to permit fair collecting. However, by hard work I managed to get a considerable number of insects of all orders. Coleoptera were comparatively scarce, as were also the night flying moths, and very few of the latter were taken at night. The best night catch of moths was made dur- ing a rain storm. No sugaring was attempted. Vegetation is pro- lific, and the timber line is well toward the top of the main range (11,000 feet). During the month of August the nights and morn- ings are quite cool and fire is necessary for comfort. When I returned to Philadelphia and mounted the material col- lected, I turned it over to various specialists for study and determin- ation, and feel very grateful to the entomological friends who have so kindly aided me. I am specially indebted to Prof. T. D. A. Cock- erell, who generously placed in my hands all his valuable records. In addition to his own collecting he also includes the material cap- tured by Willmatte Porter (now Mrs. Cockered), and his late son. Martin D. Cockerel!. This material he had determined by students TRANS. AM. ENT. SOC, XXIX. DECEMBER. 1902 36 HENRY SKINNER, EDITOR. of the various orders. I wish to mention the kindness and courtesy shown me by Col/F. A. Blake and his family, and a]so Mr. Barker. There are other lists that the student may consult with profit in conjunction with this.

The female was described by the same author in the Can. Ent. in 1883. A few females have heen taken in Colorado and Nevada. Strecker described a female from the Rio Florida, S. W. Colorado, in 1883, under the name aberration nokomis. In 1900 Prof. Cockerell found a variety of the species at Beulah which he named nigro- coerulea. This species has heen one of the great rarities in collections, and it is probably due to the fact of its late flight and very local habitat. It was abundant after the middle of August below Barker's ranch (7200 ft.), but I did not see a single specimen in the canon above this place. Their headquarters seemed to be between Barker's saw-mill and Heinlen's ranch. Their flight is swift and the species is wary, but is readily taken if approached carefully while it is feeding on the flowers of a tall sunflower which grows rather abundantly at this place in the INSECTS OF BEULAH, NEW MEXICO. 37 Thecla crysalus Edw. titus Full. ealanus Him.

Most of the females were taken in a damp meadow near some old build- ings below the saw-mill. Violets grow in profusion in this meadow. The males when not feeding on the sunflowers were seen "dipping" over the meadow in search of the freshly emerged females. This habit of flight, which I call dipping, seems to be peculiar to the males of certain species of Argynnis while in search of the females hiding in long meadow grass. This is the only species in the genus, as far as I have observed, that seems partial to sunflowers. During my stay I took about one hundred specimens and could have obtained many more. Mrs. Cockerell succeeded in obtaining eggs of the species. I have received the variety coerulescens described by Dr. Holland from Mexican specimens, from the Santa Catalina Mountains in southern Ari- zona. Nitoeris is a fine species and its varieties are handsome, and doubtless other forms of the species will be found when the high mountain valleys of the Southwest are better known. The species is found as late as the middle of Sep- tember; Dr. Holland's variety having been taken in the Piedras Verdes i7100 to 7300 ft.) in Chihuahua, Mexico, September 15th. TRANS. AM. KNT.
