Notodouta ? 



Found, September 19, 1868, at Schoharie, feeding on willow, a 

 remarkable looking larva, a figure of which is annexed. (Fig. 9.) 

 The first horn-like projection is on the third segment, the second and 

 longest on the fourth segment, the large bifid hump on the eighth 

 segment, and a terminal one on the eleventh ^^^- ^• 



segment. The markings of the larva are ex- 

 ceedingly delicate in whitish and various shades 

 of brown, finely reticulated. The long flexible 

 horn of the fourth segment is capable of considerable motion, and is 

 sometimes directed backward. The terminal segments are at times 

 carried in an elevated position. When at rest, fiq. lo. 



the central segments are contracted as repre- 

 sented in the figure, and its head and anterior 

 segments are turned sideways. When extended 

 in feeding it presents the appearance shown in 

 outline in Fig. 10. 



I have met with the larva on this occasion only. Without taking 

 a description of it, I forwarded it to Prof. Glover, of the Agricultural 

 Department at Washington, for figuring and description, and was 

 informed by him that he had seen a single example of it, and had 

 already given a representation of it in one of his plates. The imago 

 was unknown to him. 



Edema albifrons {Sm.-Abh.). 



Late in November, twelve naked pupae of this species were found 

 lying in a cluster on some leaves beneath a stone. Kept in a warm 

 room, the moths emerged between January 9th and February 11th, 

 all during the night time. 



The larva is described in the Harris Correspondence, p. 304. 



Cerura boreal is {Boisd.). 



Mature larva feeding on willow, September 11th, represented in

 fourth segment backward, reachinii: 

 nearly halfway down the side on 

 the sixth segment, and after a con- ^H^"/°/ ./r
