The head-capsule has the usual Hexatomine shape as described 
for the genus Erioccra by Alexander and Lloyd; labrum oval with 
a strong, rather chitinizeci frame; on the cephalic margin prociuced 
into a small median lobe bearing two small tubercles (Plate I, Fig. 
5 ) ; the lateral margins are prociuced into prominent lobes which are 
directed inward and cephalad, entirely protecting the front of the 
labrum and almost meeting one another on the middle line; these 
lobes densely hairy. Antennas cylindrical, bearing two or three 
small hairs and one much longer hair (Plate I, Fig. 3). Man- 
dibles long, slender, acutely pointed as in the members of this tribe, 
with a very large tooth on the inside near the middle of its length, 
this latter with a smaller tooth at its base, the inner margin basad 
of these two teeth is roughened with two or three tiny denticles 
(Plate I, Fig. 1). 
Stigmal field with four lobes of which one pair are lateral and 
directed caudad and slightly laterad, the round stigmata at the base; 
the outer face of these lobes is provided with numerous long hairs, 
these being longest at the tip, shorter at the base. The ventral 
lobes are longer, directed caudad, the tip provided with a few long 
hairs and some shorter ones which are continueci up the ventral 
face. The dark markings on the stigmal disk are few, a broad 
brown suffusion extending from the stigmata dorsad; a narrow 
brown line along the inner face of the lateral lobes, this mark nar- 
rowest at the tip, scarcely enlarged at the opposite end; the ventral 
lobe has a long slender brown mark extending from the tip cepha- 
lad, at the proximal end expanded (Plate T, Fig. 7). 
Described from numerous larvae taken at Ithaca, N. Y., May 
6, 1914. 
Pupa 
The pupa is quite similar to that of Eriocera longicornis differ- 
ing only in its small size, greater development of the scapal spine, 
lack of the projection on the mesonotal praescutum, etc. The 
cephalic crest when viewed from beneath is very different in shape; 
the fore pair of legs are much shorter than the others, ending just 
beyond the caudal margin of the second abdominal segment; the 
hind pair extend far beyond the others, ending beyond the middle
