The head-capsule has the usual Hexatomine shape as described 

 for the genus Eriocera by Alexander and Lloyd; labrum oval with 

 a strong, rather chitlnized frame; on the cephalic margin produced 

 into a small median lobe bearing two small tubercles (Plate I, Fig. 

 5) ; the lateral margins are produced 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 cauciad, the tip provided with a few long 

 hairs and some shorter ones which are continued up the ventral 

 face. The dark markings on the stigmal disk are few, a broad 

 brown suffusion extending from the stigmata dorsad; a r: i '*^" 

 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 I, 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
