like spots having a red centre and a black margin and connected 
by a longitudinal white line, on each side of the body, and a red 
caudal horn. It lives on Spermacocce Hyssopifolia, and, like the 
other species, is transformed in an imperfect cocoon which it spins 
above ground. Pupa clay-colored, freckled with dusky spots. It 
inhabits the Southern States, the West Indies, and South America. 
I am indebted to Dr. J. E. Holbrook of Charleston, S. C., and 
to Dr. H. B. Hornbeck, of St. Thomas, W. L, for specimens. 
The antenne are straight, with a shorter terminal hook than in 
the three preceding species; the outer margin of the fore-wings 
is not so sinuous, and the abdomen is much more elongated, slen- 
der and pointed. It may be necessary, hereafter, to institute a 
new genus for the reception of this and several other closely al 
lied West-Indian and South-American species.

Olive-brown ; fore-wings with a pale buff-colored stripe from

broods of this species in the course of one summer.
