from Claremont, Cal. The last is part of a good series fotiiiil in the 

 National Museum material, for which we are indebted to the Museum 

 authorities. 



Perditus in a general way resembles corvus, but the pale costal 

 line is not interrupted above the base of the cleft, there is no spot 

 before the cleft, and the abdomen is of normal length. It is also 

 similar to costatns but so much smaller that it is very easily disting- 

 guished. The genitalia are distinctive. 



The life history is imknown to us.

Head pale brownish above and in front, broadly wliitish between antennae. 

 Palpi moderately long, oblique, very slender, whitish. Antennae whitish. Legs 

 wliitish, the first two pairs shaded with gray-brown inside. 



Primaries yellowish white to very pale brownish gray, always with a darker 

 shade of a more or less brownish color in the costal region. This shade is 

 usually, however, inconspicuous. The veins in the second lobe are often slightly 

 darker than the ground color. Fringes and secondaries very pale brownish 

 gray. Expanse 14-22 mm. 



Distribution : S. Tex. and Ariz, north into Utah and Cal., Mar., 

 May, July, Aug., Oct. Type locality Mendocino Co., Cal., May. 



We are rather doubtful of this species as we limit it here, but 

 are unable to divide it satisfactorily either by superficial characters or 

 genitalia. We sent Meyrick a rather yellowish specimen, and he re- 

 turned it with the note: "probably not correct, but there is little to go 

 by, your example being worn ; it is rather larger than the two types 

 (which are in very good order), segiuents of forewings apparently 

 narrower and more pointed, tone of forewings yellower and less 

 grayish ; true inconditus is very uniform and dull-coloured, wings 

 shorter-looking." Later we were able to compare the paratype 9 

 in the Fernald collection with our entire series. Judging by Meyrick's 

 note, this paratype does not dififer from the types in the British Mu- 

 seum, and we are able to check the points which he mentions, but
