seventh is the largest joint in the antenna; the eighth is minute, 

 but not nearly so much so as in monilis ; the ninth is as broad but 

 shorter than the seventh ; the tenth is a little narrower than the 

 ninth, and the eleventh a little narrower than the tenth, otherwise 

 they are nearly of the same size. The antennse are brown, with 

 the exception of the two first joints which are clear ferruginous, 

 and the three last which become gradually paler to the tip. The 

 head and mouth are broad ; the former is rugosely punctate and 

 darker than the rest of the body. The thorax is short, darkest 

 in the middle, transversely rugose. The elytra are very distinctly 

 transversely strigose ; there is a sutural stria impressed on them. 

 The scutellum is small, elongate triangular, depressed, and darker 

 than the elytra. The whole body is covered with a dense fuscous 

 pubescence of the same colour throughout, but throwing a 

 reflexion like a lighter band across the elytra towards the apex 

 when viewed in certain lights. The under side is of the same 

 colour as the upper. The legs are paler; they are very distinctly 

 spinose, a character which is found in other species, but which, 

 from being very marked here, I have taken to furnish a suitable 

 name to the species. The middle tibise are a little bent. In the 

 males the anterior tarsi are widened, but the middle tarsi are not. 

 Found at Caraccas by M. Salle, and presented to me by 

 M. Chevrolat. 



Group III. 



Mesosternum keeled ; middle tarsi alike in both sexes. 



1st Subdivision. Body polished and shining ; the elytra not 

 transversely strigose.

" Oblongo-ovatus, nigro-piceus, nitidus ; antennis pedibusque fer- 

 rugineis ; thorace transverso, basi latiore lsevi ad angulos ob- 

 tusos utrinque distincte sinuato ; elytris flavo-testaceis, apice 

 piceis, passim minus profunde punctatis. 



" Long. If lin." 



Not having seen this species, I can only reproduce M. Kraatz's 

 description, which is as follows : — 



" A new species differing so much from all the species of 

 Catops known to me, by its shining glittering upper side and 

 clear yellow elytra, that I cannot class it under any one of 

 Erichsoir's groups : not only so, but I was not wholly averse to 

 have based a new genus upon it, if in spite of the many differ-
