fuscous scales in the fringe of the hind margin of the third

PLATYPTILIA SHAST^E. 



Platyptilus shastce Wlsm., Pter. Cal. and Ore., p. 14, Plate I., fig. It 

 (1880). 



As I have no example of this species, I quote Lord Walsing- 

 ham's description : 



' < Head white ; palpi white, touched with cinereous at the sides ; 

 antennae dotted above. Thorax dusted with cinereous. 



u Fore wings narrow, whitish, dusted with cinereous atoms, 

 especially along the costa ; the triangular costal patch brown, fol- 

 lowed by the usual pale space ; a brown line along the base of the 

 white fringes ; a very slender whitish line, running parallel to the 

 apical margin, terminates in a white dash on the costa, reaching 

 to the extreme apex; the antemedian dots scarcely indicated. 

 Hind wings pale cinereous, the third lobe perhaps slightly the 

 lightest in color; fringes nearly unicolorous, pale cinereous, 

 scarcely paler at their bases. Abdomen yellowish white. The 

 third pair of legs cinereous, slightly whitish below each joint and 

 on the spurs and feet. Expanse 20 mm." 



Habitat. California. 



" This species maybe distinguished by its slender appearance 

 and narrow fore wings, which are so delicately dusted as to be of 

 almost the same shade as the pale cinereous hind wings, which 

 separate it at once from any of its allies now described." 



PLATYPTILIA FRAGILIS. 



Platyptilus fragilis Wlsm., Pter. Cal. and Ore., p. 16, Plate I., fig. 12 

 (1880). 



Expanse of wings, 19 mm. Head and thorax white, sprinkled 

 with yellowish scales ; palpi slightly cinereous ; abdomen yellow- 

 ish ; legs yellowish white, brownish at the joints. 



Fore wings fawn color with yellowish tinge ; the two antemedian 

 spots and the triangular costal patch brown ; outer margin brown- 

 ish. Fringe white with a fine brown line at its base. Two brown 

 dashes in the fringes of the hind margin before the anal angle. 

 Hind wings very pale brownish white with paler fringes. 



Habitat. California. Early stages and food plant unknown.
