No. 1375. TINEID MOTHB FROM BRTTIStl COLVMBtA—BVSCK. 749 



Abdomen dark fuscous, each joint tipped with wliite scales. Legs 

 greenish fuscous, annulatcd with white. P^xpanse, 17-18 mm. 



Food j)lant. — Balsainon^hiza sagittata. 



Habitat. — Pullman, Washington, June. 



Type.—C2it. No. 7810, U. S. National Museum. 



Described from a large series bred in June 1)3^ Mr. C. V. Pi])er. 



The species is very close to Cluweutis silplucUa (jrotc. and may 

 ultimately prove to be merely a variety of that species. In view of 

 the different food plants and locality and of the slight l>ut apparently 

 constant differences in ornamentation, I believe it safer to separate it 

 from that species. In this connection 1 may offer a dissenting opinion 

 from the recently adopted view that Chalcsela gemmalis Ilulst" is a 

 synonym of Choreutis sllphiella Grote. '' The descriptions cei-taini}- 

 do not read alike, and while they ultimatel}^ may be found to applv to 

 varieties of the same species, the assertion of Mr. W. D. Kearfott,'' 

 who admits that he knows the species merely from description, that 

 the two are " manifestly " synonyms, is not in agreement with the 

 opinion of the two recognized authorities, who had the specimens 

 before them and both declared the Sierra Nevada form an allied l)ut 

 distinct species. Until more ample proof is forthcoming it is safer to 

 admit that we do not know. Choreutis halsamoiThiseUa may be the 

 same as the Sierra Nevada species, though Hulst's description does 

 not agree fully with the specimens before me. More authentic 

 material from the different localities, together with a careful exami- 

 nation of the types, is necessary to settle the matter. 



CHOREUTIS PIPERELLA, new species. 



Antennas black with silvery white annulations. Labial palpi oehre- 

 ous speckled with black and white; tuft black and white; terminal 

 joint, whitish sprinkled with darker scales. Face and head golden 

 orange, speckled with black and white. Thorax and basal fourth of 

 forewings light golden orange; a longitudinal streak on the patagia 

 and a subcostal and a central longitudinal on the base of the wing 

 bluish metallic. 



The ground color of the rest of the wing is golden green, heavily 

 overlaid with cream-colored scales. There are three conspicuous 

 velvety black spots with metallic bronzy center, one large one at the 

 end of the cell, a smaller one before it in the cell and one at torn us. 

 Above these spots are several scattered golden metallic scales. Cilia 

 brown. 



Hind wings dark fuscous with a single white dash and a whitish 

 submaroinal line around the wing. Underside with irregular white
