PLATYPTILIA PICA. 

 Amblyptilus pica Wlsm., Pter. Cal. and Ore., p. 21, Plate II., fig. 1 (1880) . 



I have never seen this species, and therefore repeat Lord Wal- 

 singham's description : 



u Head and palpi cinereous, dusted with white scales. Antennae 

 cinereous, faintly dotted with whitish above. The thorax white 

 touched with cinereous above and at the sides, with two black 

 spots behind. 



" Fore wings white, dusted with cinereous along their costal half 

 before the fissure ; the costa fuscous, dotted with white ; a blackish 

 spot before the middle of the wing touching the costal shade ; 

 another nearer to the base below it ; a blackish fuscous, triangular, 

 costal patch before the fissure, followed by a conspicuous white 

 space, beyond which is a fuscous shade, crossing both lobes, di- 

 vided by a white line running parallel to the apical margin, on 

 which the cilia are white, dotted with some fuscous. The dorsal 

 half of the wing is less shaded or dusted than the costal, and con- 

 tains two short, oblique, blackish dashes near the middle, the 

 second being followed by a straight streak of brownish fuscous 

 scales running parallel to the dorsal margin. The cilia on the 

 dorsal margin are white, with two distinct tooth-like tufts of black 

 scales ; the cilia within the fissure are fuscous. 



' ' Hind wings fuscous brown, with cilia of all the lobes the 

 same color, except on the dorsal margin of the third, where they 

 are white, irrorated with black scales along the basal half, and 

 bearing a conspicuous projecting triangular tuft of black scales 

 beyond the middle, and a few more below the apex of the lobe. 



" The abdomen is white above and beneath, with a fuscous line 

 along each side, which also crosses it above near the base, and 

 again below the middle. The third pair of legs are annulated 

 with white and fuscous brown, the bases of the white spurs being 

 also fuscous. Expanse, 23 mm. 



"It is allied to A. acanthodactylus and A. cosmodactylus of 

 Huebner." 



Habitat. California. Early stages and food plant unknown.
