 distinctly emarginate on lower side. t Retocomus

I. Retocomus Casey. 1895. 



This genus comprises most of the species formerly classed under 

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

 of the five recognized species occurs in the State. 



2463 (7869). Retocomus wildii Lee Proc. Phil. Acad. Nat Sci VII 1855 

 270. ' ' • ' 



Elongate, subcylindrical. 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; under surface and legs brownish, densely clothed 

 with gray hairs. Thorax subcordate. 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 (Amorpha fruti- 

 cosa L.) and osage orange. 



II. Stereopalpus Laf . 1849. (Gr., " solid + palpus..") 

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

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

 pes, 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 :
