Psecadia delliella n. sp. 



Expanse of wings, 2 1 mm. Palpi white, with the outside of the first 

 two joints black. Head white. Antennae brown, white above basally. 

 Thorax snow white, with two black bands, one across the middle and the 

 other across the scutellum. 



Forewings snow white, with a satin lustre and crossed by five more 

 or less interrupted nearly equidistant bluish-black stripes. The first is 

 nearly straight and extends from the costa nearly across the wing ; the 

 second crosses at the basal fourth of the wing and is angulated outwardly 

 near the middle of the wing ; the third arises from the costa just before 

 the middle, is angulated outwardly at the middle of the wing and ends at 

 the middle of the hinder margin. This stripe is sometimes interrupted 

 near the middle, and is more or less completely connected with a spot 

 outside of it on the upper side of the cell. The fourth stripe starts from 

 the outer fourth of the hinder margin and extends up to the fold where it 

 stops. A little above and outside of this is an elongated oblique spot. 

 The fifth stripe runs from the anal angle up to the end of the cell where 

 it branches, one branch continuing in the same course up to the costa but 

 broken at the point of branching, the other branch extending obliquely up 

 and inward nearly to the costa where there are three or four costal marks 

 of different sizes. Outside of this stripe, on the middle of the wing, are 

 two dashes, not in the same line, but sometimes connected. About nine 

 spots of unequal size, more or less confluent, rest on the outer edge of the 

 wing, three on the costa and the rest on the outer margin. A small black 

 spot rests on the base of the costa. The basal half of the fringe is orange 

 yellow and the outer half smoky-brown. 



Hind wings, above and beneath, white basally, pale fuscous apically, 

 fringes white. Underside of forewings dull whitish, with fuscous along the 

 costa and outer border, and faintly showing the marks of the upper side. 



Abdomen dark smoky brown, the segments edged with whitish. Anal 

 tuft, and second segment orange yellow. Underside white with a black 

 spot on the middle of the basal part of each segment. Forelegs black 

 with the joints tipped with white, and the fore coxae are white with a
