filiform, fuscous, the basal joints ferruginous, the two apical 

 joints pale ; first and second joints long and slender, those follow- 

 ing short, gradually though very slightly increasing in breadth 

 up to the seventh ; the seventh is rather shorter than the ninth, 

 and of about the same thickness ; the eighth is not narrower than 

 those on each side of it, but shorter, being about half the length 

 of the ninth ; the ninth and tenth are equal in length and thick- 

 ness ; the eleventh is larger than the tenth, and becomes acu- 

 minate towards the point. The head is darker than the rest of 

 the body. The thorax forms a continuous or nearly continuous 

 line with the elytra ; its posterior angles do not project behind ; 

 both thorax and elytra are seen under a powerful lens to be very 

 finely though distinctly transversely strigose. The elytra are not 

 truncate, although they are rounded rather rapidly at the apex. 

 The scutellum is not visible. The sutural stria is distinct at the 

 base, but it draws closer to the suture as it proceeds to the apex, 

 and is lost before it reaches it. Under side and legs ferruginous- 

 brown. 



Erom Caraccas. I received this species from M. Deyrolle, 

 under the manuscript name of aquinoctialis ; but the advantage 

 of having a name bearing reference to some particular character, 

 when that can be had, is so obvious, that I am sure that that 

 excellent entomologist will excuse my not adopting the name he 

 had destined for it.

 Long. 1J lin. 



Oval, lightly convex, black, with black pubescence. 

 Antennas of the length of the head and thorax, the 

 apex slightly thickened, the eighth joint narrower 

 than those next it, black, piceous at the base. Thorax 

 about the same breadth as the elytra, with the sides 

 lightly rounded, the posterior angles slightly projecting obliquely 

 behind, nearly right-angled ; the base subsinuate on each side, 

 finely transversely strigose. Elytra transversely feebly strigose, 

 the strigations rather widely separated, impressed with a sutural 

 stria, rounded at the apex. Legs concolorous, tarsi piceous, the 

 anterior lightly dilated at the base in the males. Mesosternum 

 slightly keeled. 



This species seems to come between strigosus, Kraatz, and 

 sericeus.
