bluish gray, and the maculation is clearly written and black. Dr. Dyar 

 can hardly have had both these species before him when he wrote strigata 

 as a synonym of solidaginis. I have three good males under present 

 observation from as many localities in Washington, taken in March and 

 April. The type came from Victoria, British Columbia. 



Albicinerea is a very bright gray species, the markings smoky, but 

 clearly defined. The median, lines are very much better marked than 

 usual in this genus, and in one example the t. p. line is completely trace- 

 able. The secondaries in the male are smoky throughout and only a 

 little paler at base. Three specimens from Alberta and Manitoba are 

 at hand. 



Brucej is a sordid ashen gray form in which the transverse maculation 

 is nearly all lost and the black streakings are accompanied by rusty brown 

 stains. The head and thoracic disk are also rusty brown. The secondaries 

 are dull, even, smoky gray. There is only one male, from Garfield 

 County, Colorado, elevation 6,000 feet. 



Cucullia albida, Sm., is also a member of this genus, as is proven by 

 a male example now before me. It is distinct from all the others by the 

 whitish primaries, on which the markings are very faintly written. It is 

 almost as much a Cucullia in wing form as is solidaginis, and, indeed, 

 except for the totally different colour, is a closer ally lo it than to any 

 other species in this genus. 



In sexual structures the males are very much alike. In all cases there 

 is a rather slender harpe coming to an oblique or acute point, and there is 

 a long, curved, corneous hook as a clasper. The structure is distinctive 

 for each; but the similarity is obvious. In the antennal structure, also, 

 there is no striking difference between the species. 



Rancora Brucei, n. sp. — Ground colour a dull, powdery, ashen 

 gray. Front, centre of collar, disk of thorax and dorsal tuftings of the 

 abdomen tinged with rusty ; other thoracic parts a little paler gray ; 

 powdery. Primaries with the transverse maculation practically obsolete. 

 The t. a. line is barely indicated by a slightly darker tooth in the sub- 

 median interspace. There is a short black streak on the inner margin 

 near the base. There is a slender, continuous black line through the sub- 

 median interspace from the base to the s. t. space, and this line is a little 

 relieved by accompanying pale scales. There is a distinct black curved 

 streak above the inner angle, and this is margined with rusty brown. 

 Smaller, less conspicuous streaks are in the two following interspaces, and
