The fera.ile oi" this species, which much resembles that of several of our rainphilidi 

 besides its congener, may be distinguished from most of them by the purplish tinge of 

 the under surface of the hind wings; from Thymelicus aetna, with which it agrees in 

 this respect, by the lesser breadth of the vague e.^tra-mesial pale Isand on the same sur- 

 face; and from its congener, by the spot in the lower median interspace of tlie fore 

 ■wing which is lierc much less conspicuous. 



Accessory sexual peculiarities. The discal stigma of the male has been de- 

 scribed under the wing; tlie scales contained in it consist of jointed tlireads (51 : 4 d) 

 iu the heart of the stigma, and at the b.ase of the stigma are found not only some very 

 stout, two-pronged rods (4 c) but also some exceedingly slender awl-shaped rods (4 b) , 

 enlarging very slightly and gradually at the apex. In the vitreous .spot of the lower 

 interspace of the female are found some quadrate scales with rounded sides, rather 

 broader than long, the entire margin finely striate and with waved reflections (4 a). 



Egg (66:32). Entire surface covered with a flue tracery of exceedingly delicate, 

 raised lines, forming polygonal cells which are higher than broad above, the reverse 

 and subquadrate below, and on lower half of sides forming wavy pseudoribs by being 

 subcontinuous ; interspaces punctate, most profusely on lower half. 



I am not quite sure that this figure and brief description belong to this species. 



Distribution (31 : 7) . This Alleghanian species has a wide distribu- 

 tion, especially in the west, extending from the Atlantic seaboard to the 

 Rocky Mountains, where it was found long ago by Reakirt in Colorado, 

 has since been found in the same state by Putnam, Snow and Packard, 

 and comes from as far south as New Mexico (Snow) and as far north as 

 Montana and Dakota (Morrison). Its western distribution, however, is 

 uncertain, for, occurring as it does upon the Pacific coast itself in northern 

 California and southern Oregon (A. Agassiz), it must be found in the 

 interveninff reffion from which it has never been obtained. East of the 

 Rocky ^Mountains it occur.s as far north as Dakota, Iowa, where it is a 

 common species (Allen and others), Wisconsin (Hoy), southern Michi- 

 gan, common (Harrington), Nepigon, north of Lake Superior (Fletcher), 

 London, rare (Saunders), and Sudbury, Ont. (Fletcher), Ottawa, rare 

 (Billings, Fletcher) and Montreal, not common (Caulfield). On the 

 south it extends as far as Virginia (Mus. Anicr. Ent. Soc.) and "West 

 Virginia (the same) in the east, and Dallas, Texas (Boll) and New 

 Mexico (Snow) in the west. 



In New England it is widely spread, altliough it has been taken but 

 rarely in the northern half, — at Norway (Smith), Hallowell (Miss Wads- 

 worth) and Portland, Me., common (Lyman), and Thornton, N. H. 

 (Thaxter). Still it is not uncommon at Walpole (Smith) Milford (Whit- 

 ney), and even at Plymoutii, N. H. (Scudder), in Massachusetts is found
