HYPERCOMPA SYBARIS. 187 
tlie 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 antenna?, in both sexes, distin- 
guish the Lithosiidse from the Arctiidce, we find 
the present insect possesses the long spiral tongue 
of the former, and the male the pectinated antenna 
of the latter family. 
The whole colour of this 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 wings, 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 wings is two inches and a 
half.
