In one male received from the American Entomological Society, while 

 the wings are well angulated, the miter line is much straighter than usual, 

 being bul slightly sinnate, as is the lint- on the bind wings; bu1 otherwise it 

 does nut differ. 



This is our most common species, and is at once known by the much 

 speckled wings and ochreous-bordered, blackish lines. It varies greatly in 

 the distance apart of the two lines, which, in the lore wing, are in some twice 

 as wide apart as in others. 



This species is so variable that I have been able to find varieties corre- 

 sponding to Hiibner's fervidaria and GueneVs fiscellaria. About Gj-ueneVs 

 fiagitiaria 1 do not feel so sure ; but while it is a distinct variety, 1 find forms 

 of fervidaria which correspond to it, the lines being dark. Walker's speci- 

 mens in the British Museum labeled E. fervidaria, fiscellaria, and fiagitiaria, 

 arc different forms of the same species. 



Hiibner's figures of T. fervidaria differ from the normal form of the 

 species, namely, T. fiscellaria, in the male wings being scarcely angulated, in 

 f he outer line on the fore wings being bent backward and inward on the costa. as 

 no other species has it, and he docs not represent the lines as showing 

 through on the under side, as those vd. fiscellaria do decidedly. Plate 12, fig. 

 2, represents the ordinary form (— Gruene'e's fiscellaria), and fig. 3 the 

 variety with simply sinuous lines, which is Hiibner's fervidaria. 



Idle five males and one female from Vancouver's Island are larger, but 

 do not differ so much from eastern examples as the latter among themselves. 

 They are more yellow, with coarser dark speckles, and the lines are more 

 broadly shaded with yellow. The length of one fore wing is 0.85, while that 

 of a large eastern example is 0.73 inch. Certain eastern examples from 

 Salem are colored much as in the Vancouver's Island ones. The examples 

 from Salem are deeply suffused with dark beyond the cxtradiscal line, the 

 shade extending half-way to the edge of the wing, while the inner line is 

 \cvy diffuse. 



Larva. — Body cylindrical, smooth ; head of the same width as the body. 

 Body yellowish-green above, pale purplish below. Two fine, blackish, lateral 

 lines, with a pale line above. Pupa rather slender, whitish, slashed and 

 spotted with brown. Food-plant, Halesia diptera. — (Described from Abbot's 

 .MS. drawing.)
