254 CUKCULIONID^. 



[LeC'onte. 



ly subcarinate, with a smooth narrow median line; antennit 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 bisinuate, medial angle small, distinct; scutel- 

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

 prothorax at base, humeri rectangular, slightly rounded, not prominent, 

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

 subquadrate punctures, interspaces some wiiat 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 variable; 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 

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

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

 imens there 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. minutissimus, n. sp. 



Oval, moderately elongate, brown, varied with blackish 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; short, stout, erect bristles are intermixed. 

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

 nae 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 feebly bisinuate, median 

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

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

 slightly rounded, then obliquely narrowed to the tip; striaj composed of 

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

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

 gulated near the l)ase; tarsi as in the preceding species. Body beneath 

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

 2.5 mm. ; .10 inch. 



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

 tliis very pretty little species. Col. Molschulsky gave me two individuals 

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

 never published. In generic characters this species difiers greatly from 

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



8. O. 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
