Pupa. — Robust, the abdomen regularly tapering, the segments 

 coarsely, rather densely punctured anteriorly; wing cases creased and 

 shagreened. Cremaster large, thick, constricted at the base, coarsely 

 densely wrinkled; upper hook single, strongly recurved; lower hooks, 

 four or five on each side, well separated and bent down subparallel to 

 the surface of the pupa. 



Food plant. — Poplar.

Ground color white, quite strongly powdered with black. The ordi- 

 nary lines distinct in most cases and always traceable. Basal line 

 marked by a black spot on the costa. Transverse anterior line marked 

 by a black costal spot, and from this point it is geminate, with an even 

 outcurve, to the middle, where it meets the basal dash and begins 

 another even outcurve to the internal margin. The line is rarely 

 entirely complete, but its geminate character is marked in all the 

 specimens that are before me, and it is in almost every instance trace- 

 able on both sides of the basal streak. ^ The median shade is marked by 

 a black spot on the costa, and as a rule extends across the reniform, 

 but not beyond. The transverse posterior line is quite usually com- 

 plete, lunulate, and (|uite strongly dentated on the veins; sometimes 

 the line is quite narrow, and sometimes dentated in both directions. 

 More usually the luuules are quite distinct, generally the line is some- 

 what emphasized opposite the cell, and is also more distinct opposite 

 the anal angle, where it is usually crossed by a black dagger mark. 

 There is a series of terminal dots, beyond which the fringes are cut 

 with black. There is a distinct black basal streak, which extends to 

 iind is connected with the transverse anterior line. The orbicular is 

 marked in all the specimens that I have seen, and, though small, is 

 black ringed. The reniform is usually an indefinite dusky lunule, but 

 is sometimes completely outlined and large kidney shaped. The sec- 

 ondaries are white, usually with a terminal dark line, sometimes with 

 a series of terminal dots. Beneath white, more or less powdery, with 

 an outer discal line and a more or less evident discal spot. 



Expanse, 1.50 to 2 inches (37 to 50 mm.). 



Habitat. — Long Island, New York; Manchester, New Hampsliire; 

 Florida; Kansas in September; Volga, South Dakota; Colorado; Mon- 

 tana. 



The only date of capture that I have for this species is September, 

 and unfortunately the entire collection contains only nine specimens. 

 These, however, run very constant, and in the characters that I have
