[I>eConte. 



ly subcarinate, with a smooth narrow median line; antennte brown with 

 slender funicle; club oval -acuminate, annulated. Prothorax wider than 

 long, narrowed gradually in front, broadly rounded on the sides, strongly 

 constricted near the tip, deeply and densely punctured ; very finely carinate 

 behind; base rather strongly bisiuuate, medial angle small, distinct; scutel- 

 lum very small, covered with white scales. Elytra very little wider than 

 prothorax at base, humeri rectangulai-, slightly rounded, not prominent, 

 sides parallel, then obliquely narrowed to the tip; striae composed of large, 

 subquadrate punctures, interspaces somewhat convex; third and fifth more 

 elevated. Legs slender, thighs with one very small tooth; tibiae straight, 

 outer edge angulated near the base; tarsi as in the preceding species. 

 Length 4.3 mm. ; .17 inch. 



Illinois to Texas. The size of the thoracic and elytral dark space is some- 

 what vai'iable; it may, however, be stated in general terms, that it occupies 

 nearly the whole of the base of the prothorax, and narrows to the apex, of 

 which it covers the middle third; it extends on the elytra from the humeri 

 obliquelj^ backwards, ending on the suture about the middle; in other spec- 

 imens tliere is a brown, irregular band behind it and connected with it, 

 but this is probably produced by an abrasion of the scales. The body be- 

 neath is densely clothed with dirt colored scales. 



I have adopted the name given in Dejean's Catalogue. 



7. O. rainutissimus, n. sp. 



Oval, moderatelj^ elongate, brown, varied with Ijlackish spots, clothed 

 with black, brown and pale scales; the latter forming an elongate basal 

 spot on the prothorax, and a transverse band behind the middle of the 

 elytra, angulated at the suture; sliort, stout, erect bristles are intermixed. 

 Beak stout, flattened, punctured, naked from the tip to the middle (anten- 

 nx not seen). Prothorax wider than long, narrowed gradually in front, 

 moderately rounded on the sides, strongly constricted near the tip, not cari- 

 nate, postocular lobes nearly obsolete; base very feebl}' bisinuate, median 

 angle very obtuse, indistinct. Scutellum liardly visible. Elytra very little 

 wider than prothorax at base; humeri rounded, not prominent; sides 

 sliglitly rounded, then obliquely narrowed to the tip; striae composed of 

 large punctures, which are concealed by tlie scales, so that the striae appear 

 to be fine and impressed. Thighs unarmed; tibiae straight; outer edge an- 

 gulated near the base; tarsi as in the preceding species. Body beneath 

 deeply and densely punctured; clothed with dirt colored scales. Length 

 2.5 mm. ; .10 inch. 



Virginia to Louisiana. I have adopted the Catalogue name of Dejean for 

 this very pretty little species. Col. Motschulsky gave me two individuals 

 as his Acalles pictus and fascictilatus, but I believe that the names were 

 never published. In generic characters this species differs greatly from 

 Acalles, though somewhat resembling A. clavatus in size and form. 



8. C. apiculatus GylL, Sch. Cure, iv, 121. 



Florida ; Messrs. Hubbard and Schwarz. Very distinct by the prothorax 

 suddenly and strongly constricted near the tip, and by the erect, stout
