oval confluent ones, of which the lower one embraces the .sti<;ma con- 

 necting with its superior margin — the next of equal size or broader — 

 the ujjper one, quite small, resting on the incisure, near the sub-dorsal 

 line, — the three ranging transve'-sely, and anteriorly from the stigma, 

 unlike the lateral bands of nearly all of the Sphingidae, which are 

 directed posteriorly. 



Pupa. One in my possession which there is every reason for believ- 

 ing it to belong to this species, differs in the following particulars from 

 mtclb'tla. The head-case is rather short. The antennae-cases of the 9 

 extend slightly beyond the anterior leg-cases. The elevated medial 

 line of the third segment is prolonged over the posterior ridge to the 

 incisure, and is more prominent. The eleventh segment is broader 

 than the posterior portion of the tenth, and is abruptly rounded. The 

 twelfth segment is sub-rectangular inferiorly, and instead of a terminal 

 spine, it has simply an obtuse tuberculated projection. Size of .sa<e/- 

 litia. The pupal transformation occurs ordinarily about the middle of 

 August. 



The Imago is met with less frequently than satellitia. I have taken 

 it in June, at twilight, about the flowers of the Evening Primrose 

 ( (Enothera biennis), the culture of which, in a lar^e cluster, I would 

 commend to collectors, from its having given me several of the rarer 

 Sphinges. 



Deilephila Cham^^neru Harris. 

 Larva. 3 in. long. Head, dull red, small, exceeding slightly in 

 diameter, the first segment. Body tapering gradually from the ninth 

 segment to the fourth, thence rapidly to the head, and slightly from 

 the ninth posteriorly; incisures, rather deep ; color, dark brown, ap- 

 proaching black. The vascular line, dull red. The annulations of the 

 segments conspicuous on their posterior half. Midway between the 

 vascular line and the stigmata, on the central segments, a row of dull 

 white spots, nine in number, placed on the anterior portion of the seg- 

 ment, sub-oval in shape, their longest diameter in line with the body — 

 the last one, elongated, and extending upward to the caudal horn. 

 Beneath these spots, the body is dotted with whitish. Caudal horn^ 

 .20 in. long, slightly curved. Stigmata, yellowish. 



The larva appears to be rare. 1 have taken it but once, on August
