second microscopically tessellate ; third to fifth segments with smaller, 

 somewhat closer punctures, apical segment microscopically punc- 

 tulate. 



Hab. — On Bigelovia wrightii, close to the Agricultural College, 

 Mesilla Valley, New Mexico, Sept. 12, 1895 (Ckll., 5,096). This has 

 something the appearance of G.fuscus Tasch., but will be known at 

 once by the coarctate first segment of abdomen, and the color of the 

 antennae and legs. The submedian cell of the hind wings terminates 

 the merest^point beyond the origin of the cubital nervure and the 

 last ventral segment is not bifid, or is the fifth ventral segment 

 armed with a prominence. 

 Gorytes crucis n. sp. 



9 . — Length about 10 mm., of head and thorax 5, of anterior wing 

 11 mm., of ordinary build, bright ferruginous, with a broad yellow 

 band on scutellum, and a darker, smooth abdomen. Inner orbits 

 parallel ; front minutely granular, with rather large sparse punctures ; 

 area between the ocelli black ; space between the antennal sockets 

 slightly less than the diameter of a socket ; clypeus prominent, shin- 

 ing, its lateral margins with some short silvery pubescence, its ante- 

 rior margin gently concave; mandibles dark at tips; scape not 

 swollen, second flagellar joint about two-thirds length of first. Pro- 

 thorax (and tubercles) entirely without pale marking ; mesothorax 

 granular, with large not very close punctures ; scutellum microscopi- 

 cally punctulate and sparsely punctured, yellow, with the anterior 

 margin black ; anterior half of postscutellum black ; middle seg- 

 ment coarsely rugose-punctate, the well-defined triangular enclosure 

 strongly sulcate or logitudinally ribbed. 



Tegulse pale orange-fulvous ; wings fuliginous, with a pallid area 

 by the base of the stigma; stigma (and costal nervure) fulvous, 

 nervures dark fuscous, marginal cell quite long. Legs entirely 

 ferruginous, not very strongly spined ; claw-joint of anterior tarsus 

 much swollen, the remaining joints also somewhat enlarged. First 

 segment of abdomen coarctate ; the abdomen was unfortunately de- 

 stroyed before a detailed description had been prepared. 



Hab. — Las Cruces, New Mexico, Aug. 12 (C. H. T. Townsend). 

 Resembles tricolor and dentatusin regard to coloration, but the first 

 segment is coarctate. Its coloration and robust form easily disting- 

 uish it from the species with a coarctate segment heretofore known. 

 Using the table in Proceedings of the Academy of Natural Sciences 

 of Philadelphia, 1895, p. 517, it runs at once to G. rufocinctus, from 

 which it differs entirely in coloration. It has some degree of re-
