costal edge in two, small, indistinct, geminate, white streaks. From two 

 similar costal streaks just beyond the middle of the wing runs a narrow, 

 outwardly angulated, fascia of shiny hyaline scales across the wing. At 

 apical third is a similar, but nearly straight, transverse fascia. The two 

 latter fascia? contain on the middle of the wing a few black scales. Before 

 the apex are two small, silvery, costal streaks and the terminal edge is 

 rather broadly suffused with similar silvery scales. All of the silvery mark- 

 ings appear to be slightly raised. Cilia bluish white with two transverse, 

 blackish lines. Hindwing light fuscous; cilia whitish with a fuscous basal 

 line. Abdomen silvery fuscous. Legs silvery fuscous; tarsi with indis- 

 tinct, blackish brown annulations. Alar expanse: 12-19 mm. 



Habitat: Fort Bayard, New Mexico, G. E. Bushnell, collector- 



Foodplant: Pinus ponderosa and other pines. 



Type: Cat. No. 18439, U. S. N. M. 



This species is named in honor of the collector, Colonel G. E. 

 Bushnell, to whom is due credit for all the information we have 

 on its biology. 



The larvae feed gregariously in the terminal twigs of Finn* 

 ponderosa and other pines and appear to be severely injurious to 

 these trees. 



The full grown larva is 14 mm. long; body of a reddish yellow 

 color; tubercles not distinguishable; hairs short, white. Head 

 light yellowish brown with black eyespots; thoracic shield small, 

 darker brown. Feet normal, abdominal feet small with a single, 

 complete circlet of uniform hooks. 



The moths from overwintering pupae produce an early summer 

 generation, the adults of which issue about July first. 



The species, which may have been introduced into New Mexico 

 with the trees, is very close to the eastern Evetria frustrana Coin- 

 stock, but averages considerably larger and differs in the details 

 of ornamentation, and in the character of its work. It is the 

 same species which for several years has been excessively injuri- 

 ous to the pine plantations of the U. S. Forest Service at Halsey, 

 Nebraska. (See Forestry Quarterly, Dec. 1910.) 



Evetria virginiana n. sp. 



Labial palpi, face and head light whitish yellow. Antenna- reddish white 

 with a thin, longitudinal, black line anteriorly. Thorax reddish brown, 

 with a central transverse band suffused with white scales and wit lc t he pos- 

 terior tip and the tips of the patagia white. Forewings broad and ample, 

 rich reddish brown with a number of irregular, pearly white, transverse, 

 forked and anastomizing lines with violet sheen, which terminate in five 

 small, geminate, white costal streaks. The narrow areas surrounded by 

 these transverse lines arc of a somewhat lighter yellowish brown. This is 

 particularly the case with one on the middle of the wing and one near tor-
