284 AMERICAN MICRO-LEPIDOPTERA. 



costal streaks, of which the former points slightly outwards. The latter is per- 

 pendicular, reaching nearly (or in some specimens quite) to a white patch on the 

 dorsal margin before the apex, which seems to consist of two confluent white 

 dorsal streaks. At the extreme apex is a minute black apical spot, surrounded 

 by a semi -circular dark line at the base of the apical cilia, which are tinged with 

 golden saffron at the extreme apex. Beneath the apex the cilia are white, 

 blending into saffron-gray about and before the anal angle ; all the white mark- 

 ings are distinctly dark margined on all sides. The white streaks on the fore- 

 wings of this species are so large and conspicuous as in some cases to almost 

 obliterate the pale saffron ground color, and different specimens vary much in 

 the proportionate space occupied by one and the other. 



"Hindwings and cilia pale gray. Abdomen and anal tuft grayish white. 

 Hind tarsi whitish, spotted above with gray. Expanse alar, 9 mm." 



This species was described as above by Lord Walsingham from 

 specimens collected in California in 1871, in Lake and Mendocino 

 Counties in June, and on Mt. Shasta, Siskiyou County, in August. 

 In Mr. Kearfott's collection, there is a specimen of this species from 

 Carmel, California, taken in June (A. H. Vachell, collector).

Face, head and thorax white. Palpi white. Scales of the tuft mixed with 

 gray. Antennae remarkably dark gray, with the basal joint white. Upper side 

 of the abdomen dark gray. Anal tuft somewhat lighter, tinged with yellow. The 

 underside of the abdomen is brownish white; as are likewise the legs, the tarsi 

 on the outside being obscurely dark spotted. The ground color of the forewings 

 is a deep saffron brown. The white spots are greatly developed on the dorsal 

 margin, but, on the contrary, only slightly on the costa. Here, beginning just 

 before the middle of the costal margin, are four white streaks dark margined on 

 both sides. The first is placed very obliquely, the second less so, the two last 

 are placed transversely on the wing, are bent, and their apices point toward the 

 tornus. At the base of the dorsal margin there is a very large white spot. It 

 forms an irregular quadrilateral, which approaches the costa, extends parallel to 

 it, and is prolonged to a point on the fold. An obliquely placed transverse band 

 of the saffron brown ground color, very much darkened, borders this spot behind. 

 Then follows a second white mark, in the shape of an irregular triangular, whose 

 broad base rests upon the dorsal margin. There follows a second, also very much 

 darkened shorter transverse band. It ends at one-half the wing length. Behind 

 this at the tornus, we see finally the last white triangle. At the apex of the 

 wing there is a black dot. A well defined black streak extends from this dot 

 into the whitish cilia. A peculiar glistening blue line extends along the base of 

 the cilia. This line becomes very noticeably slightly concave before the tornus.
