THALEROPIS. 167 



larva, however, which is smooth and tapering at the ends, with 

 two short horns on the head and a bifid tail, prove it to be 

 allied to Apatura, from which the Butterfly differs by its hairy 

 eyes and closed wing-cells. 



As the Butterfly is a species of considerable interest, and 

 has only hitherto been figured in a few scarce and expensive 

 continental works, we are glad to give it a place on one of our 

 plates. One or two African species have lately been referred 

 to Thaleropis, but it is not quite certain that they actually 

 belong to that genus.

This Butterfly is found on the southern shores of the Black 

 Sea, at Amasia, &c. It measures about an inch and three 

 quarters across the wings, which are of a yellowish- fulvous, 

 sometimes varied with white and yellow. The base is broadly 

 b ] ack, and there is a small eye at the hinder angles of all the 

 w'ngs. There are also some irregular basal spots. The under 

 side of the hind-wings is blue or yellow, with a dark central 

 band, not reaching quite across. 



Although Eversmann's and Herrich-Schaffer's descriptions 

 and figures were published in the same year, the official permit 

 in the work of the former bears date January 10, whereas the 

 parts of Herrich-Schaffer's work, in which the insect was in- 

 cluded, are only the third and fifth of the eight parts pub- 

 lished during 1851
