48 REVISION OF GENUS CUCULLIA—SMITH. 
The entirely concolorous dorsum of thorax gives the most obdvious fea- 
ture. The secondaries are like the ¢ of speyert or the 2 of letifica, q 
and, judging from these species, the male has a much narrower pale — 
border to secondaries. j 
The sexual structures of the male will probably differ little from those _ 
of speyeri. 
Cucullia bistriga sp. nov. = | 
Ground color bluish ash-gray. Frontal vestiture with a considerable - 
admixture of black scales. A black line at base of collar and a brown- — 
ish line near its tip. Patagie with a submarginal dusky line. A brown, — 
quite prominent, discolorous, metathoracic tuft. Primaries with all the 
veins narrowly black-marked, a dusky shade over the costa, and short, — 
narrow interspaceal black lines. in terminal space. ‘. a. line single, — 
dusky, giving a long tooth into the median cell, a second into the sub- © 
median interspace, and a third to margin. ‘T. p. line single, blackish,  , 
even, outcurved over cell and then parallel to outer margin. WReniform — 
vague, dusky, moderate in size. <A distinct black streak along the 4 
inner margin from base to t. p. line; another from the angulation of t. — 
a. line in submedian space along the fold to s. t. space, then obliquely — 
upward to outer margin between veins 2 and 3. A small subapical 
brown shade. Secondaries whitish basally, with an indefinite outer 
dark border; fringes whitish. Beneath grayish-white, powdery, pri- 
maries with a vague, dusky discal spot. 
Expands 35 millimetres=1.40 inches. . 
HABITAT: Colorado (Bruce). : 
A very distinct species, differing from all the others at a glance. — 
Two males, both taken by Mr. Bruce, one of them from Mr. Neumoegen’s — 
collection, are before me. The sexual characters are unique. The harpes 
are parallel, the superior angle of tip slightly produced. A chitinous — 
ridge extends from the superior margin, near base, diagonally along and — 
across the harpe, reaching the inferior angle of tip and there somewhat 
elevated and produced. :
