costa and outer edge. Hind wings ash, mottled densely with brown 

 scales ; discal dot distinct ; the wings darker on outer half beyond 

 the single distinct brown line, with a dusky patch in the middle of 

 the wings adjoining the line. 



In the 9 there is no line on fore wings. The hind wings are more 

 angulated and dentated than in H. marcescaria. 



Length of wing, .56 ; body, $ .45 inch. Edwards and Behrens. 



Tephrina marmorata n. sp. ?. 



Closely allied in form and markings to T. strigularia, wrongly re- 

 ferred by Mr. C. S. Minot (these Proceedings, vol. xn.) to Anisopteryx. 

 These two species belong to a distinct section of the genus, and at 

 present I refer it to Tephrina, though I need more material to under- 

 stand the genus better. The front of the head is much fuller, and 

 the wings are more pointed, and the palpi are quite short, projecting 

 but a little distance beyond the front. Body and wings pale ash with 

 a testaceous hue ; a little deeper hue on the outer edge of both wings. 

 The costal edge is marked with minute strigae, most distinct on the 

 extreme edge. A square whitish spot on the inner third of the costa, 

 and an outer white distinct line broadest on the costa, disappearing 

 before reaching the inner edge of the wing, bent on the first median 

 venule. The fringe on both wings is white, checkered with large 

 square brown spots ; no discal spot above or below on either wing 

 Under side of fore wings bathed with yellow testaceous, veins distinct, 

 testaceous; extreme costal edge dark, with white strigae. Outer white 

 line faintly reproduced, making with the white apex a rude V, en- 

 closing a triangular mottled space ; remainder of the wing clear of 

 scales. Under side of hind wings marbled beautifully, the ground 

 color being white, with dark strigae arranged in broken bands ; a 

 central broad band angulated on the independent venule, with yel- 

 lowish spots, especially on the venules, and the wing within is 

 densely strigated, with the median area white, with a few brown 

 strigae ; from the inner angle arises a broad band which terminates 

 on the first median venule. The outer edge of the wing is sprinkled 

 with brown, especially on the apex and costa ; elsewhere it is pure 

 white. 



Probably from near the snow line, as our New England species was 

 found by Mr. Sanborn on the summit of Mt. Washington. 



Length of body, .50; fore wing, .75 inch. 2 ?. Edwards. Nevada.
