inches and resembles, at fii'st sight, Heinaris rather than Lepkesia, 

 though the outline of primaries is nearer to Lepiseda. Mr. Strecker 

 gives no account of whether the legs are armed or not, and I place 

 the insect in its present position from the general appearance rather 

 than from any actual conviction that it belongs here.

Wings entire. Head and thorax aliov^e of a peculiar grayish brown, concolor- 

 ous with anterior wings. Abdomen darker, blackish. The ])re-anal segments 

 pale yellowish. Anal tuft black, divided ; anal segment with black tufted scales. 

 Beneath, the palpi are white, and the under thoracic surface is white mixed with 

 slaty gray. Legs finely scaled, slight, obscurely colored. Primaries dark at 

 base, where thei"e are a few paler scales. A double black transverse line. The 

 middle of the wing is concolorous with the thorax above. A di.scal black ab- 

 breviated line. Below the third median nervule this line is continued to in- 

 ternal margin. A faint sinuate line before the extremity of the middle field of 

 the wing ; this paler middle of the wing is limited by a deeper and diffuse black- 

 ish line coincident with the firet and faint transverse line. Outside of this 

 deeper line the terminal portion of the wing is obscurely darker than centrally, 

 fringes tinted like the paler ground color of the wing. Secondaries black at 

 base, with a very broad, pale yellowish white median band, and a deep black 

 even terminal band. Fringes yellowish white. Beneath, the primaries are 

 whitish, the veins darker, terminal space darkly shaded. Secondaries yellowish 

 white, except a terminal black band. Expands 1.25 inches ; 32 mm. 



Hub. — California. 



Also a rare species, the early stages of which are not known. It 

 is readily distinguished from all its allies by the very pale yellow 

 secondaries. The specimens that I have seen show little or no varia- 

 tion.
