ly82,] NEW SPECIES OF RHOPALOCERA. 397 



in B. vulcanus is not the case, but the black has rather a greenisli 

 reflection. Tlie red of the band is in H. vulcanus more fiery, the 

 band itself on an average narrower, on the outside tootlied, and 

 extended further down. Ou the upperside of the hind wings the 

 anterior margin in the males of H. vulcanus is yellowish, whilst in 

 //. venus it is grey. 



The fringe in H. vulcanus is distinctly veined black and white, in 

 H. venus it is clear white. This can only be seen in fresh specimens. 



On the underside of the fore wing the red band in H. vulcanus is 

 fainter, in the middle especially mixed with white, which is not the 

 case in H. venus. At the base of the anterior margin is found in 

 H. vulcanus a short sharp red streak, which is always wanting in 

 H. venus. 



On the underside of the hind wings the yellow streak of the 

 anterior margin in H. venus is usually rather broader and longer ; it 

 is especially different in the yellow middle band, which in //. venus is 

 always longer and bent upwards at the pointed end, usually extending 

 upwards nearly to the margin. In the shorter band of H. vulcanus 

 the obtuse end bends, on the contrary, rather downwards. In 

 H. vulcanus also it is sharply defined, and not so in H. venus. In 

 some specimens of H. vulcanus, both male and female, it is entirely 

 wanting. H. vulcanus has always close to the base one or two red 

 j)oints, which are very rare in H. venus. 



Both species have the palpi white beneath, and spots on the head 

 and prothorax. The short fore legs are white in H. venus, but 

 yellowish in fresh s[)ecimens of H. vulcanus. The underside of the 

 abdomen is also yellower in H, vulcanus than in H. venus. 



Heliconius godmani, sp. n. (Plate XXIV. fig. 3.) 



I received a small number of this species, which I name in honour 

 of Mr. F. DuCaue Godman, also through Herr E. Trotsch, from the 

 Rio San Juan, in Western Colombia. H. godmani is nearly allied to 

 H. gyncesia, Hew., but is certainly distinct from it. 



The fore wings in both are black with yellow spots ; but the spots 

 are different : H. godmani has on the end of the jjosterior margin a 

 rather long yellow stripe, which is wanting in H. giincesia. 



On the outer margin are seven or eight oblcng yellow spots, of 

 which those near the apex are smallest, whilst in H. gyncesia these are 

 the largest. Before these are three other yellow spots, aud far below 

 them a fourth, which, in H. gyncesia, is close to them. 



Above the medium cell on the costa is a small double spot as in 

 H. gyncesia ; besides this there is also another yellow spot in the 

 middle cell which is absent in H. gyncesia. A male shows also at 

 the base of the cell a fine yellow streak, which on the underside is 

 large, triangular, and somewhat forked ; and all the other spots of 

 the upperside are, beneath, rather more strongly developed. 



The hind wings are, in the females, red-brown with broad outer 

 margin, on which are seven (in one female eight) oval yellow spots, as 

 in H. gyncesia. 



Beneath are eight yellow spots, and at the base of the anterior
