5 . — Ochreous and vermillion. Head ochreous. Palpi vermillion, 

 clothed beneath with ochreous hairs, apical joint black. Antennae 

 brown, slightly vermillion at the base. Thorax and patagia hairy, 

 ochreous, the patagia much less distinct than in H. tessdlaris. Abdo- 

 men hairy, vermillion above, pale ochreous beneath, as is also the 

 thorax. Legs pale ochreous, tibiae and tarsi annulated with brown, 

 tibial joints also marked with the same color. Tibiae vermillion inside. 



Primaries very thinly scaled, subdiaphanous, ochreous, with five pow- 

 dery smoky brown bands, the first at the base very incomplete; second 

 strongly arcuate outwardly; third straight, not oblique; fourth and fifth 

 nearly parallel with the outer margin, which is also broadly of the same 

 color; the third and fourth bands are fused on the inner margin, form- 

 ing a V. In specimens at all worn these markings are only clearly 

 visible on the costa and inner margin. 



Secondaries nearly colorless, diaphanous, slightly vermillion on the 

 inner margin, narrowly dusky at apex. 



Beneath, the markings of the primaries are faintly reproduced. On 

 the secondaries the costa is opaque, ochreous, with two brownish spots. 

 ? resembles the 3 , except that the abdomen is less hairy and is or- 

 namented on the three terminal segments v»*ith a blackish, dentate, dor- 

 sal mark, widest on the terminal segment. 



Expanse of ivings, 1.80-2. 10 ins. Lejtgth of body, 0.85-0.90 in. 



Habitat. — California, (Coll. Edwards, Behr, et als.) 



Larva. — Length, 1.50 inches. Head dark brown, very large. Tho- 

 racic legs reddish brown, abdominal legs tawny. Body stout, depressed, 

 densely clothed with moderately long rich brown hairs of uniform 

 length, giving the larva a brush-like appearance. The sides of the body 

 as well as the caputal and anal segments, have scattered long silky hairs 

 of a tawny yellow. The cocoon is composed chiefly of the hairs of the 

 larva, and although of considerable density, is but slightly bound to- 

 gether with silk, of w'hich a very small quantity is used in its construc- 

 tion. The larva is full fed about the end of June, and the imago is 

 disclosed during the latter part of July.
