Moth.— Male and female. Head large and prominent, a little wider than in Heterocompa. 

 Palpi short and broad. Fore wings more produced toward the apex, which is pointed, outer edge 

 long and very oblique, no subcostal cell (for other details of the venation see PI. XLVII, tigs, i, 4«), 

 but otherwise the venation is much as in H. astarte and obliqua. Hind wings slightly shorter 

 and more rounded at the apex than in Heterocampa. 



The fore wings are rather more clear of markings than in Heterocampa, being whitish gray 

 with dark blotches at the base of the wing and near the outer edge. Hind wings with a difl'use 

 whitish extradiscal line. 



When we take into account the lack in the adult of the subcostal cell and the presence in 

 the larva of perfect stemapoda and its lateral yellow bars, it seems best to separate this species 

 from the genus Heterocampa as Dr. Dyar has done, and which I had been inclined to do for some 

 time. 



Larva.— Body long and slender, ending in a pair of twin stemapoda, as well developed as 

 those of Cerura; no prothoracic tubercles in the last stage; body pale green, with a dorsal pink 

 hue, and obliquely barred, sphinx-like, on the sides with yellow. 



Freshhj hatched larva. — Stemapoda nearly as long as the body, with a pair of erect prothoracic 

 tubercles, a slight broken dorsal line the.only marking. 



Cocoon. — Oval, elliptical, thin translucent. 



Pupa.— Body thick, plump, head with prominent ridges on the vertex; cremaster ending in 

 two stout diverging couical spines.
