2. — Tribe Telamonini Godg. 



A. Pronotum unarmed. 



B. Dorsum strongly compressed foliaceous 1 — Archasia Stal 



AA. Pronotum armed with a horn or dorsal crest more or less developed. 



B. Dorsum armed with a compressed horn, which is erect or nearly so, with a 

 dorsal crest more or less elevated. 



C. Dorsal crest arising from behind the suprahumerals. If distinctly ele- 

 vated, wider than high. Corium coriaceous, and if at all punctured, 

 only for a short space at the base. 



D. Dorsal crest rounded; obtusely pointed, truncate or sinuate at 

 apex, sometiuu's scarcely elevated 2 — Tclamona Fitch 



1. — Genus Archasia Stal. 

 A genus whose species are green when alive, turning oreheous or 

 tawny in museum specimens. Prothorax punctate and finely althougli 

 obscurely dotted with white specks. Longitudinal median carina piceous 

 in spots. Prothorax very highly elevated and compressed into a sharp 

 helmet above the head. 



Archasia galeata Fabricus. Figs. 22, 23. 



This is the only species of this genus reported from Kansas. There 

 are two species classified by Van Duzee, but the F. H. S. collection yields 

 but one specimen of each of the two species, and A. belfragi is not re- 

 ported from Kansas. On account of the scanty material, very little study 

 could be made. 



Contour of the prothorax entire, not having elevations or sinuations. 

 Metopidium bears short, obtuse suprahumerals. 



Habitat: Van Duzee reports the species from Colorado and Georgia, 

 stating that it is less abundant than A. belfragii Stal in the Northern 

 States, but is a prevailing form in the South. The specimen in the 

 F. H. S. collection is from Douglas county, Kansas. 



Length, 9.5 mm. 



2. — Genus Telamona Fitch. 



This genus contains the largest form found in Kansas, it measuring 

 sometimes 11 mm. in length. The male is much smaller than the female 

 and also darker in color. 

 .V. Crest (viewed laterally) pyramidal, rather slender and narrowed upward. 



B. Crest narrowing above to a rounded point, posterior angle scarcely if at all 

 indicated, its front sloping from the metopidium without a sinus at the an- 

 terior base 1 — pyramidata Uhl. 



A-\. Crest (viewed laterally) rectangular, broad, but little narrowed above. 



B. Crest nearly vertical before or sometimes overhanging. Gray or brownish 

 species more or less distinctly banded or dotted with dark brown, sometimes 

 almost black. 



C. Crest truncated above, the angles nearly or quite right angles. 



■2 — ampelopsides Harris 



1. — Telamona pyramidata Uhler. Figs. 30, 31, 84. 



Color varying from a pale, tawny concolorous specimen through green- 

 ish ochre to brown with darker markings. In cephalic aspect the form is 

 very broad and somewhat flat; the metopidium curves backvrard after 

 rising perpendicularly for a short distance, and gently upward, forming 

 a dorsal elevation back of the suprahumerals. This elevation or pro- 

 tuberance slopes abrubtly downward and then proceeds in an almost hor'-
