OF WASHINGTON. 95 



This and the following species belong to the group of the 

 genus Ethmia which is represented by the European pyrausta 

 Pallas. The species of this group, which probably should be 

 given generic rank, differ from the typical species of Ethmia 

 in the scantier, more hair-like scaling and in the somewhat 

 shorter and weaker labial palpi, which are not smooth as in 

 the typical forms, but covered with a more or less strongly 

 developed brush of thin hairs on the under side of second joint. 



None of the hitherto described American species belongs in 

 this group. The present species is nearest the European auri- 

 fluella Hiibner, but differs in the unicolored abdomen and in 

 the presence of the orange ornamentation of the fore wings. 

 This and the following species are at once distinguished from 

 all American and European species by their striking white, 

 dark-bordered hind wings. 



Ethmia coquillettella, n. sp. 



Antennae purplish black. Labial palpi black, with base of both joints 

 white; second joint with short rough brush beneath. Lower part of 

 face and the region below the eyes white; vertex black. Thorax dark 

 brown; tips of patagia white. Fore wings mouse-gray, somewhat 

 lighter than in the preceding species ; at base is an inconspicuous light- 

 yellow spot edged exteriorly with black. Just outside it is a longi 

 tudinal deep black dot on the fold and on the middle of the fold is 

 another similar dot. On the middle of the wing is a third similar 

 black dot and at the end of the cell is a fourth somewhat larger black 

 spot, divided in the middle by a large round white or very pale yellow 

 dot. Cilia concolorous with the wing. Under side of fore wing dark 

 gray, with the white second discal spot prominently shining through. 

 Hind wings clear pearly white, with a broad dark gray border on apical 

 and tornal edges but not on costa nor on the base of the dorsal edge. 

 Abdomen above dark fuscous, with bright ochreous anal segment; 

 under side with each joint tipped with white. Legs black, sprinkled 

 with silvery-white scales; tarsal joints tipped with white. 



Alar expanse, 15' mm. 



Los Angeles, Cal. (D. W. Coquillett). 



Type. No. 9900, U. S. National Museum. 



This species is nearest to the foregoing, but much smaller 

 and differs otherwise in the shorter brush on the labial palpi, 

 in the absence of the yellow discal streak on the fore wing, 

 by the incomplete dark border on the hind wings, and by the 

 ornamented abdomen and legs. Named in honor of the col 

 lector, who has added many interesting species of Microlepi- 

 doptera to the Museum collection.
