Hab. — California (Crescent City). 



The type ( $ ) in Lord Walsingham's collection. I have not seen 

 this species. 



I. solenobiella Wish. — Dyar's List, p. 569, No. 6485. — "Head and palpi 

 whitish. Antenme cinereous, somewhat annulated with whitish towards the 

 base; slightly pubescent in the male. Forewings whitish, thickly sprinkled with 

 rather shining, yellowish brassy scales, more conspicuous in the female than in 

 the male, and grouped into irregular blotches, especially along the apical margin 

 and about the middle of the wing. Cilia whitish. The hindwings are pale, gray- 

 ish cinereous, the cilia the same. The male is slightly larger than the female, 

 and has more the appearance of a Solenobia, especially when slightly worn." 



Exp. % , 18.0 mm. ; ? , 16.0-17.0 mm. 



Hab. — California (near S. Francisco). 



The above is Lord Walsingham's description. Not known to 

 me in nature. 



I. punctiferella Wish. — Dyar's List, p. 569, No. 6483.— Antennse half as 

 long as forewing, straw colored at base, brownish beyond. Palpi very short, de- 

 pressed, third joint half as long as the second. Head and thorax straw colored. 

 Forewings pale straw colored, with from 18-20 chocolate-brown colored spots, 

 varying in size, number and distribution; those on the outer half of the wing 

 have a tendency to form two oblique lines, running parallel to outer margin; 

 base of costa tinged with brown; underside brownish; cilia pale. Hindwings 

 cinereous gray; cilia concolorous; underside pale grayish.

 Dyar's List, p. 573. 



Head rough haired. Labial palpi semi-ascending, spreading, 

 robust and of moderate length ; second joint thickened towards the 

 apex and roughened beneath with lateral and apical setse, third joint 

 nearly as long as the second, grooved beneath longitudinally, scaly. 

 Maxillary palpi plicate. Antenna? of moderate thickness, a little 

 over one-half the anterior wing length, tapering towards the apex, 

 joints close set with verticillate scales, uniciliate in the male. Fore- 

 wings elongate oval, 12 veins, 2 close to angle of cell, l 6 simple. 

 Hindwings rhomboidal, as wide as the forewings, costa nearly 

 straight, dorsal margin strongly rounded to the apex, 7 veins, 2 re- 

 mote from angle of cell, 3 wanting. Posterior tibiae rough haired. 



Chambers describes the palpi as devoid of bristles, they are well 

 marked in fresh specimens, the third joint is not merely flattened but 

 sulcate beneath, and the hindwings are not wider than the forewings.
