16 ZYGCENIDiE AND BOMBYCID^ 



slight indication of a discal dot, and an outer transverse row of three 

 pale yellow spots, the inner one large and sub-orbicular, the two outer, 

 small and faint, and more or less connected with powdery yellow 

 scales. Beneath, as above, except that the discal spot on the secon- 

 daries is more distinct. Fringes, long and black, except at the apices 

 of all the wings, where they are white. All the wings show a few 

 scattered yellow scales. 



Expanse of wings, ? . 1.65 inches. Length of body, $ . 0.65 inch. 



Habitat. — California. (Coll. Edwards, Behrens and Stretch). 



Allied to A. mariposa, Grote, (Trans. Ent. Soc, Vol. i.) if it be 

 not a variety of the same species. It differs from Grote's species (loc. 

 cit. ) in the following particulars : In wanting the yellow orbits to the 

 eyes; in having the collar yellow instead of black; in having orange 

 colored tufts on the tibiae of the middle pair of legs; and in the union 

 of the two outer spots on the primaries into one lunate spot, with the 

 extremities of the crescent, club-shaped. Three specimens agree'with 

 the above description so* closely, that although the difference between 

 this species and A. Mariposa are slight, they appear to be constant. 

 The large elongate wings of this species, separate it widely from all 

 the other species of this genus, except A. Mariposa, and perhaps A. 

 Grotei, Boisd. The latter insect is yet unknown to me.
