TRIBE I. — HARMOSTINI. 275 



than third, fourth stouter, fusiform ; beak reaching middle 

 coxae; pronotum much as in Haniwstcs, the margins finely crenu- 

 late, disk with a vague linear elevation each side of middle, 

 reaching from apical to basal fourth, with an oblong shallow 

 impression between them ; abdomen rather widely inflated at 

 middle, the connexivum broadly exposed, its margin curved ; 

 legs short, hind femora scarcely passing fifth ventral, not 

 greatly swollen, the apical half armed beneath with fewer and 

 smaller spines than in Harmostes. One species is. known. 



203 (341). Aufeius impressicollis Stal, 1870, 222. 



Oblong oval, depressed above. Pale grayish-yellow, thickly marked 

 above with fuscous dots and punctures; head dull yellow; antennae dusky 

 brown; connexivum alternated with fuscous and dull yellow; membrane 

 whitish hyaline, immaculate, not or but slightly passing abdomen; under 

 surface and legs dull yellow, more or less mottled with fuscous and with 

 a blackish spot behind each of the front coxae. Head granulate-punctate, 

 subquadrate behind the antenna?, the tylus convex. Pronotum with humeri 

 obtusely rounded, side margins but slightly concave; disk finely and 

 densely punctate, the hind margin subtruncate. Scutellum similarly 

 punctate, the apex rounded with margins reflexed. Elytra in great part 

 membranous, hyaline, the veins coriaceous, elevated, the clavi alone punc- 

 tate, and only at base. Sternal pleura densely punctate; ventrals mi- 

 nutely transversely striate. Length, 5 — 6 mm.; width, 1.7 — 2 mm. 



Marion and Vigo counties, Ind., Sept. 12 — 21 (W. S. B.). Den- 

 ver, Colo., July 13; Faywood, N. Mex., June 5 {Gerhard). 

 My single Marion county specimen was swept from the borders 

 of a timothy meadow, while the Vigo County one was taken 

 from the window of the high school building in Terre Haute. 

 Its known range extends from Ohio west to South Dakota and 

 Colorado and southwest to Texas, California and Mexico. Os- 

 born and Drake (1915, 506) recorded it as taken in large num- 

 bers at Columbus, O., while sweeping grasses on the university 

 farm. Uhler (1877, 407) swept it from bushes in the suburbs 

 west of Denver, Colo., and says that "some of the more mature 

 specimens were powdered beneath with a white mealy sub- 

 stance." The abdomen in the Indiana and New Mexico speci- 

 mens at hand is thickly sprinkled with small reddish points and 

 has two rows of irregular blackish spots on each side. In the 

 Colorado one it is devoid of the reddish points and thickly mot- 

 tled throughout with fuscous. While closely resembling some of 

 the species of Harmostes it is easily recognized by the dilated ab- 

 domen and by having the elytra in great part membranous.
