The species was figured in our Contributions Vol. I, No. 4, PI. 23, 

 Fig. 11. 



ACIDALIINAE 



COSYMBIA UMATILLARIA Stkr. 



The species, described under Anisodes, and at present listed under 

 Cosymbia, proves, on an examination of the type $ in Coll. Strecker 

 at Chicago, to be Glena cognataria Hbn. 



ACIDALIA ANCELLATA Hist. (PI. XV, Fig. 18). 



There seems to have been some mix-up in the types of this species 

 and those of A. fuscata Hist. The former species was ostensibly de- 

 scribed from 2^3? from Sierra Nevada Mts., Calif., and Arizona ; 

 in the Hulst Coll. the only type present is a S from Hot Springs, New 

 Mexico, which is certainly spurious ; in the Neumoegen Coll. is another 

 spurious $ type from the same locality but also a $ type from Ari- 

 zona which is in our opinion the one that should hold the name, thus 

 restricting the type locality to Arizona which would not alter the usual 

 conception of the species. A. fuscata was described as a variety of 

 quinquelinearia Pack, from "1 $ 1 9 Arizona, Coll. Neumoegen and 

 Hulst" ; the Neumoegen Coll. contains 1 $ (not 9 ) type from Sum- 

 mit, Sierra Nev., Calif., and the Hulst Coll. another $ type from the 

 same locality, both agreeing with the meagre description in being dull 

 gray with the maculation very similar to that of quinquelinearia; it 

 would almost seem as if Hulst had separated out his Sierra Nevada 

 specimens from ancellata after the description was written but had 

 forgotten to change the text and then placed the erroneous locality of 

 Arizona in his description of fuscata; as the 'type' of this latter species 

 in the Hulst collection does not contradict Hulst's diagnosis we think 

 it would be wise to consider this the true type and the species an in- 

 habitant of the High Sierras. It differs from quinquelinearia in the 

 more rounded secondaries, the grayer color and the straighter sub- 

 marginal line of primaries, being much closer to the Colorado luteolata 

 in everything except color. We figure a typical ancellata $ from 

 Colorado and also a specimen of our conception of fuscata (PI. XV, 

 Fig. 12) from Lake Tahoe, Calif. 



ACIDALIA PERSIMILIS Hist. 



After seeing the types in the Hulst and Neumoegen Collections 

 we are forced to the conclusion that the species is the same as Pack- 

 ard's quadrilineata.
