PUPAE.

The present paper deals entirely with species in the United States 

 National Museum that have been reared in connection with the forest 

 insect investigations of the Bureau of Entomology, either by the 

 writer at the Eastern Station at Falls Church, Virginia, or by other 

 workers of the Division of Forest Insects at the Pacific Slope Station 

 at Ashland, Oregon. In each case the original collector's name and 

 the "Hopk. U. S." number of the experiment are given. Some thirty- 

 odd forms are treated. From these are erected 1 new genus, 16 new 

 species, and 2 new varieties. Two older species are reduced to the rank 

 of varieties and full larval descriptions are given of 8 species, 6 of which 

 represent genera hitherto midescribed in their immature stages. Five 

 similar pupal descriptions are also given. 



The drawings which accompany this paper and which give it special 

 significance were made by Miss Mary Carmody and Miss Eleanor 

 Armstrong of the Bureau of Entomology, under the immediate super- 

 vision of the author. It will be noted that, wherever possible, the 

 male genitalia of the type specimen of each new species has been 

 figured. These organs, heretofore so little used in the Microlepidoptera, 

 offer excellent characters for the separation of species, genera, and 

 families and will have to be reckoned with in future attempts at classi- 

 fication in that group.

EVETRIA COLFAXIANA Kearfott. 



Evetria colfaxiana Kearfott, Trans. Amer. Ent. Soc, vol. 38, Jan., 1907, p. 3. 



Evetria sishyouana Kearfott, Can. Ent., Mar., 1907. 



Evetna taxi/ohellaBv scK, Proc. Ent. Soc. Wash., vol. 16, 1914, p. 146. 

 This species was originally described by Kearfott from a single spec- 

 imen collected by Arthur Vachell at Colfax, Placer County, California. 

 Later he described Evetria sisHyouana from two collected specimens, 

 one male from Siskiyou County, California, and a male from Oregon.
