196 THE CANADIAN ENTOMOLOGIST. 



Olyntha Brasiliensis ? Burm. Handb. vol. ii., p. 770. 



Winged form: Length of body 7 mill.; exp. of wings 14 mill. (41 

 mill, is a misprint, McLachl.) 



" Nigra vel nigro-picea ; prothorax flavo-ferrugineus ; antennas nigrae, 

 20-articulatae, articulis quinis ultimis flavidis, pallide pilosis ; alae breves, 

 latae, nigro-fuscae, albido 5-striatae." — McLachlan. 



For the detailed description the original should be compared. 



Hab. — Amazon's coll. by Mr. Bates, one specimen in McLachlan's 

 coll. I have no specimen before me. The identity of Burmeister's 

 species with E. Batesi is at least probable ; if it belongs to a different 

 species, it would be new. The differences to be noted out of Burmeister's 

 description are as follows : O. Brasiliensis Burm. has 30-jointed antennae, 

 " apice albis " ; E. Batesi only 20-jointed antennae, the apical fourth five 

 joints pale yellowish. Now, accepting that the antennae of E. Batesi 

 were incomplete, Burmeister's species, if identical, would not have the 

 tip, but the apical half pale. Burmeister has, " femoribus 4-anticis 

 ochraceis"; McLachlan, "coxae yellowish." Finally Burmeister says, 

 " cercis albis " ; McLachlan, " the 2nd joint obscure yellowish with black 

 hairs." E. Batesi is stated by McLachlan to be the broadest-winged 

 species known to him.
