of the liiiid wings. Fore wings pale straw-colour ; the costa arched somewhat abruptly at the 
base, where there is a strong chestnut-brown shade : a Ayedge-shaped spot of a similar colour 
points outwards from the costa before the middle towards the anal angle ; a narrow chestnut- 
brown shade extends vei'tically downwards from the apex halfway along the apical margin, 
the v/ing thence being rounded off obliquely to the doi'sal margin: cilia very pale straw- 
colour. Hind wings yellowish white, with a chestnut-brown shade at the apex. Legs pale 
straw-colour ; the first pair of tarsi chestnut-brown above. The female slightly larger than 
the male ; fore wings unicolorous ochreous chestnut, hind wings yellowish white : antennte 
simple. 3 1 ? • Expanse of wings J 30 millims., ? 33 millims.

In this var. the chestnut-coloured wedge-shaped mark on the costa is much occupied 
by dark fuscous scales, and it blends into a chestnut shade, which is continued along the costa 
to the apex, and downward through the wing to the dorsal margin beyond the middle, forming 
a sort of large irregular triangle, from the inner edge of which a slight projection extends 
towards the base of the wing along the fold. There is an oblique line of faint fuscous scales 
halfway between the costal wedge-shaped mark and the apex, reaching downwards towards 
the anal angle. The space between the thorax and the middle shade is o£ a more ochreous 
tint than the space beyond it above the anal angle, which is very pale straw-colour. The 
female has the fore wings darker than in the typical form, but nearly unicolorous ; a paler 
oblique fascia, scarcely perceptible beyond the middle ; tlie space above the anal angle also 
pale. 1 (J, 1 ? . Expanse of wings 30 millims., $ 33 millims. 
Both varieties of this species occur in the month of August, on the western slopes of 
Mount Shasta, California, at an elevation of about 6000 feet, among thickets of " Man- 
zanita,^' Arctostcqjhylos glauca (Lindl.), on which I have little doubt the larva feeds. In a 
considerable series I have met with no varieties intermediate between the two forms above 
described ; but it would be at least premature to consider them distinct species.

Palpi very long, projecting fully three times the length of the head beyond it ; the second 
joint nearly three times as long as the apical joint, slightly enlarged towards its base, tapering 
forward : antennae simple. Fore wings — with the costa abruptly arched near the base, straight 
beyond, the apex not rounded; apical margin straight, not oblique — tawny fawn-colour, the 
whole surface streaked with very minute detached streaks of tawny-fuscous scales in broken
