Hab.—Coso Valley, California (Koebele coll.) May, U. S. N. 

 M. type No. 9806. 



Closely allied to C. barberella, but at once distinguished from 

 all described American species by the central longitudinal 

 white streak. 



Gerostoma maculatella sp. nov. 



Antennae white, sharply annulated with dark brown except on basal 

 fourth. Labial palpi white. Face white. Head and thorax ochreous 

 white. Forewings ochreous white ; basal half of costal edge ochreous 

 fuscous. From the base runs a broad, dark, ochreous fuscous band out- 

 wards below the fold, touching the dorsal edge and then curving up- 

 wards to the fold. At the end of the cell is a large, oblong, pronounced, 

 dark fuscous spot, produced into a still larger paler ochreous patch, 

 which covers most of the apical third of the wing and emits three dark 

 fingers to the costal edge. Hind wings paler fuscous. Abdomen 

 ochreous white. Legs white, mottled with black exteriorly. 



Alar expanse, 20-22 mm. 



Hab. — Bright Angel, Arizona (Barber coll.) May, U. S. N. 

 M. type No. 9807. 



This species is nearest to C. angelicella, and quite similar 

 though not identical in design, but differs in the dingy ground 

 color and the more diffused and darker markings. 



Gerostoma vintrella sp. nov. 



Antennas white with sharp prominent dark brown annulations. Labial 

 palpi white. Face, head and thorax pure white, patagina ochreous. 

 Forewings white witji indistinct and ill-defined, light ochreous fuscous 

 markings ; the most persistent of these are a central longitudinal row of 

 three large oblong spots, more or less connected by single dark scales, 

 and a series of equidistant costal, apical and dorsal spots around the 

 edge of the apical third of the wing. There are also two ochreous 

 fuscous costal spots, one at basal third and one at the middle of the 

 wing, and two or more dorsal spots, but none of these markings 

 are very constant and in even slightly worn specimens they are all 

 more or less obliterated, so that the wing appears nearly immaculate 

 or merely dusted with dark scales. Hindwings light gray. Abdomen 

 dark fuscous. Legs white. 



Alar expanse, 17-22 mm. 



Hab. — Colorado Canon, Arizona, 2300 feet alt. (Barber 

 coll.) May. U. S. N. M. type No. 9808. 



Nearest, on account of the white color, to C. striatella, but 

 very different from that and all other described American 

 species.
