REVISION OF THE OECOPHORIDAE — CLARKE 109 



fused with carmine; tarsi annulated with whitish ochreous. Abdo- 

 men grayish fuscous above, whitish ochreous below; ventrolateral 

 lines poorly defined, black; anal tuft yellowish ochreous, suffused 

 with carmine. 



Mode genitalia. — Harpe moderately sclerotized and covered with 

 hairs over entire inner surface; costa and sacculus parallel beyond 

 middle then converging to form a narrowly rounded cucullus. Clasper 

 heavily sclerotized, smooth, short, terminating in a blunt point. Anel- 

 lus longer than broad, truncated on posterior edge; lateral lobes weak. 

 Vinculum with a very short, small dorsoanterior process. Transtilla a 

 very narrow, moderately sclerotized band with small lateral lobes. 

 Aedeagus stout, rather short and evenly tapered, terminating in a 

 sharp point. Armature consisting of many fine spinules. Gnathos a 

 heavily spined cone. 



Female genitalia. — Genital plate moderately sclerotized, broad, 

 slightly produced anteriorly. Ostium near posterior margin of plate. 

 Ductus bursae slender, gradually becoming larger till it merges with 

 the bulbous bursa copulatrix. Signum a 4-pointed, moderately sclero- 

 tized small plate with strong teeth; lateral, anterior, and posterior 

 points about equal in length. 



Alar expanse, 17-24 mm. 



Type.— U. S. N. M. No. 52081. 



Type locality. — Kamiack Butte, Whitman County, Wash. 



Food plant. — Antennaria luzuloldes T. and G. 



Remarks. — Described from the $ type, 7 $ and 4 $ paratypes, as 

 follows: Kamiack Butte, 3 5 3,25$ (V-18 to 22-34) ; 4 5 5 , 1 9 

 same (VI-15 to 19-35) ; $ , Pullman, Wash. (1-28-31 [indoor 

 record] ) ; $ , Godman Springs, Blue Mountains, Wash., 6,000 feet 

 (VIII-1-35) ; all reared from larvae collected by the author. 



Paratypes in collections of United States National Museum, Cana- 

 dian National Museum, and H. H. Keifer, Sacramento, Calif. 



Dr. J. McDunnough, of Ottawa, has sent me three specimens of 

 this species from British Columbia. The larvae, from which these 

 moths were reared, were collected by A. N. Gartrell at Shingle 

 Creek Road, Keremeos. The adults emerged from 30-VI to 

 &-VII-35. 



Mr. Gartrell has labeled his specimens as reared from wild red 

 currant. The food plant record is rather surprising since most of 

 the species of this group are host specific, and it will be noted that the 

 type series was reared from Antennaria. I have carefully compared 

 the genitalia of specimens of the two lots and find them identical.
