KEY TO INDIANA GENERA OF EURYGENIINI. 



<t. Last joint of maxillary palpi broad, hatchel -shaped; eyes narrowly and 



distinctly emarginate on lower side. I. KETOCOMVS. 



(in. Last joint of maxillary palpi long, priming-knife shaped; eyes very 



slightly emarginate. II. STEREOPALPUS. 



I. RETOCOMUS Casey. 1895. 



This genus comprises most of the species formerly classed under 

 Eurygenius Laf.. which Casey states is confined to Brazil. But one 

 of the five recognized species occurs in the State. 



24G3 (7860). RKTOCOMIS WILDII Lee.. Proc. Phil. Acad. Nat. Sci.. VII. 1855, 



270. 



Elongate, snbcylindrical. Black, head and thorax densely clothed with 

 brownish-gray hairs; elytra each with five narrow rows of similar pubes- 

 cence, these alternating with narrow black stripes bearing small isolated 

 patches of gray hairs; mnler surface and legs brownish, densely clothed 

 with gray hairs. Thorax snbcordate. about as wide as long; disk densely 

 and coarsely punctate and with a deep median impressed line. Elytra one- 

 half wider than thorax, densely and coarsely punctate. Length 10-12 mm. 



Southern two-thirds of State ; scarce. May 10-June 17. Beaten 

 from flowers, especially those of the. false indigo (Ani<>ri>li/i fniti- 

 <-<>su L.) and osage orange. 



II. STEREOPALPUS Laf. 1849. (Or., "solid 4 palpus.") 



Ciisey recognizes 11 species of this genus, seven of which he de- 

 scrihes as new. Two well-known species occur in the State and rufi- 

 />r.s\ one of Casey's new ones, was described from Indiana. I have 

 not seen specimens of it, but give his distinctions between it and 

 the others as follows : 



KEY TO INDIANA SPECIES OF STEREOPALPI'S. 



(i. Elytra 1 pubescence uniform in distribution and in general tint; head 



equal in width to thorax. 



li. 1'pper surface uniform grayish-fuscous in hue. the elytra often slight- 

 ly paler. 24G4. MELLYI. 

 bl). Elytra light yellowish-brown, always distinctly paler than thorax. 



2405. VESTITl'S. 



nu. Elytral pubescence not uniform in distribution and hue, they being 

 closely and finely mottled with small irregular clusters of slightly 

 greater density; legs dull reddish-yellow. RUFIPES.

Elongate, slender, subcylindrical. Fuscous, thickly clothed with gray- 

 ish pubescence; legs often varying to reddish-brown. Thorax bell-shaped.
