REVISION OF THE OECOPHORIDAE — CLARKE 191 



"Antenna purplish-fuscous. Palpi cinereous, speckled with fuscous 

 externally on the second joint; apical joint entirely suffused with 

 fuscous, with the exception of the apex which is ochreous. Head, 

 dull grayish-ochreous ; face paler. Thorax, cinereous, speckled with 

 fuscous. Fore wings pale grayish-ochreous, thickly suffused and 

 streaked with purplish-fuscous, the markings ill-defined, consisting 

 of a dark fuscous patch at the base of the dorsal margin, a dash of 

 the same color immediately above the middle of the wing at one third 

 from base, followed by some pale grayish-ochreous scales; a pale 

 grayish-ochreous spot on the middle of the wing at about the end of 

 the cell is preceded and followed by fuscous scales, and beyond and 

 above it are several fuscous dashes radiating outwards to the costal 

 and to the upper half of the apical margin, where is a row of obscure 

 fuscous spots preceding the somewhat paler mottled cilia. Hind 

 wings, pale shining whitish-gray, with the cilia scarcely darker in 

 which a slight tinge of grayish-ochreous is traceable. Abdomen, 

 grayish-ochreous." 



Male genitalia. — Essentially like angustati but with the posterior 

 margin of the anellus narrower and the lateral edge entire, convex. 

 The clasper is outwardly angulate instead of evenly curved. 



Alar expanse, 20 mm. 



Type. — In the British Museum. 



Type locality. — "Montana." 



Food plan t. — Unknown. 



Disfrihution. — Known only from the type locality. 



Remarks. — The above color description is taken from the original. 

 I have drawn up the brief description of the male genitalia from a 

 sketch (see fig. 200B) kindly submitted by Herbert Stringer, of the 

 British Museum. 



Mr. Stringer states {in litt.) that ''Hogata is nearest to angustati 

 but not that species," or any of the others included in this paper, 

 and of which I submitted drawings of the genitalia. 



The figure of the male genitalia is a copy of the sketch sent by 

 Mr. Stringer and shows adequately the differences between tog at a 

 and the other species. 



In 1902 ^* Busck applied the name togata to specimens from Colo- 

 rado and Vermont. The Colorado specimens, which are before me, 

 are not this species, as the genitalia indicate, but represent an unde- 

 scribed species. I am leaving this series undescribed until more 

 and better material comes to hand, because the moths are now faded 

 and were none too good when collected. The Vermont specimens 

 were probably hetulella; I know of no species in the togata-angustati 

 complex east of the Kocky IVIountains.
