Moth , — Male and female. Head large and prominent, a little wider than in Heterocompa. 
Palpi short and broad. Fore wings more prodiiceil toward the apex, which is pointed, outer edge 
long and very oblique, no subcostal cell (for other details of the venation see PI. XLVII, hgs. 4u), 
but otherwise the venation is much as in II, astnrte and obUqiia. 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 Avhitisli gray 
with dark blotches at the base of the iviug and near the outer edge. Hind wings with a didiise 
■whitish extradiscal line. 
AVhen we take into account the lack in the adult of the subcostal cell and the iireseuce in 
the laiwa of perfect stemapoda and its lateral yellow bars, it seems best to separate this species 
from the genus Heterocamiia as Dr. Dyar has done, and which I had been inclined to do for some 
time. 
Larva . — Body long and slender, ending in a p.air of twin stemapoda, as well developed as 
those of Cerura; no prothoracic tubercles in the last stage; body pale green, Avith a dorsal pink 
hue, and obliquely barred, sphinx-like, on the sides Avith yelloAv. 
Freshly hatched larva . — Stemapoda nearly as long as the body, AAuth a i)air 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 conical spines.
