HYPERCOMPA SYBARIS. 187 



the present state of our knowledge to lay down 

 characters which shall exclusively distinguish the 

 species belonging to each. Thus, although Mr. 

 Curtis asserts, under Callimorpha, that a long spiral 

 proboscis and simple antennae, in both sexes, distin- 

 guish the Lithosiidte from the Arctiidaa, we find 

 the present insect possesses the long spiral tongue 

 of the former, and the male the pectinated antennas 

 of the latter family. 



The whole colour of thi9 moth is black, with 

 numerous white spots, there being twenty of the 

 latter on each of the fore wings, and eighteen on 

 each of the hind wing9, the latter being placed in 

 three irregular rows. The sides of the head are 

 white; there are four minute white dots on the 

 collar, succeeded by a row of eight on the front of 

 the thorax; there are also two on the scutellum, 

 and the apex of each of the lappets is white ; there 

 are also two on the postscutellum, and four on each 

 of the abdominal segments. 



The specimen here figured is from St. Domingo, 

 and is contained in the collection of the Reverend 

 F. W. Hope. 



The expansion of the winga is two inches and a 

 half.
