March, igoy. BUSCK: REVIEW OF PHALONIIN^E. 27 



Alar expanse: lo-ii mm. 



Habitat: Oak Station, Pennsylvania (F. Marloff). 



Type: U. S. N. M., No. 10233. 



I take pleasure in naming this very distinct species in honor of 

 the collector, from whom I have repeatedly had interesting and 

 carefully mounted Microlepidoptera. 



The species has a certain similarity to the European angustana 

 Treitsche. 



Phalonia lavana, new species. 



Labial palpi white, shaded with light fuscous. Face and head dirty white. 

 Thorax light fuscous. Fore wings silvery white, mottled and marked with 

 black and brown. Costal edge is tinged with brown, especially at base and 

 marked with about sixteen equidistant small black streaks from base to apex. 

 On the middle of the wing three of these streaks are combined into a larger 

 spot by intervening dark brown scales, and from the spot is emitted an indis- 

 tinct, poorly defined brown shade across the wing. Basal third of the wing is 

 nearly unmottled, but the apical part is somewhat darkened by irregular 

 black striation. The apical two-thirds of the dorsal edge is also marked with 

 small black streaks and the tip of the wing is strongly mottled with black and 

 brown scales. Hind wings whitish silvery fuscous. Abdomen dark fuscous- 

 Legs, whitish; anterior tarsal joints annulated with black. 



Alar expanse: 12-13 mm. 



Habitat: Oak Station, Pennsylvania (F. Marloff) ; Hyattsville. 

 Maryland (Busck). 



Type: U. S- N. M., No. 10234. 



Phalonia hubbardana, new species. 



Labial palpi smoky white, externally shaded with fuscous. Face smoky, 

 yellowish white. Top of head and thorax yellowish white strongly sprinkled 

 with black. Fore wing smoky white overlaid with light yellow and faintly 

 mottled by transverse black striation; this striation is emphasized on the 

 costal edge, which on account of the many close short streaks appears blackish. 

 Termen and cilia black, each black scale, however, minutely tipped with white. 

 On the middle of the dorsal edge is an outwardly oblique more or less distinct 

 black streak reaching the fold. Hind wings light silvery fuscous. Abdomen 

 and legs whitish fuscous; tarsal joints blackish. 



Alar expanse: 12-13 mm. 



Habitat: Tucson, Arizona (H. G. Hubbard). 



Type: U. S. N. M., No. -10235. 



Food plant: Koeberlinia spinosa.
