stigmal field; at about midlength and lying on the lateral mar- 

 gin of the field is an elongate triangular black mark, its point 

 directed outward; from this point and the margin of the field 

 just above its tip, arise three long curved hairs directed outward. 

 The ventral marks are larger, brownish black, these marks three- 

 pointed at their dorsal end, the innermost of these points con- 

 nected with its fellow of the opposite side; just laterad of this 

 mark is a slender brown line which bears at regular intervals, 

 three long, slender, curved hairs directed caudad; at the caudal 

 margin of the large mark arise three very large hairs directed 

 ventrad and arising from a common point so that they appear 

 coalesced at their origin. Just laterad of these three bristles 

 is still another delicate hair; so that surrounding the stigmal 

 area there are about twenty of these long hairs. Caudal gills 

 four, very short and inconspicuous, hidden underneath the 

 subterminal enlargement. 



Described from one larva taken in company with abundant 

 pupae of the same species, Forest Home, Ithaca, New York, May 

 1, 1913. 



PUPA, S 



Antennal sheaths enormously enlarged, viewed from beneath, 

 the swollen bases nearly contiguous on the median line; just 

 above and entad of the cephalic inner margin of the eye, pro- 

 vided with a sharp, chitinized spine placed in an ej'e-like 

 depression. The antennae bend laterad and dorsad to near the 

 pronotal breathing horns and then ventrad, running caudad, 

 closely appressed to the ventral side of the body, lying just 

 inside the inner margin of the wing-sheath and outside the 

 second pair of legs; the tip of the antenna is just beyond the 

 middle of the fourth tarsal segment of the middle legs. In 

 older pupae the spines on the ventral side of the adult organ are 

 clearly apparent through the cuticle. Cephalic crest (plate III, 

 E) — From between the bases of the antennae arises a flattened 

 crest directed cephalad, deeply bifid by a square median notch, 

 each of the lateral lobes thus formed being provided with 

 chitinized points which are beset with sparse hairs; on each
