174 THE CANADIAN ENTOMOLOGIST. 
XYLESTHIA. 
De Ceres a NN Gp: 
Head and palpi snow white or hoary, the outer and under surfaces of 
the palpi yellowish dusted freely with fuscous ; antennae yellowish. 
Primaries yellowish, reddish yellow and stramineous, with some white 
scales, and densely dusted with dark brown and bluish black scales, the 
dusting being much more dense in the middle and costal portions of the 
wing than in the dorsal and apical portions. There is a white costal 
streak just before the cilia and another very faintly indicated before the 
middle ; dorsal cilae whitish at their beginning ; ciliae brown. Thorax 
white dusted with dark brown; abdomen dark brown; legs and under 
surface whitish, rather densely dusted with brown, the legs with white 
annulations, and the anterior tarsi darker than the others. 
There is a tuft of raised scales on the fold at the base of the 
primaries and three other large ones between the fold and the dorsal 
margin, two small ones about the end of the cell, three or four small ones 
on the disc and three or four others in the apical part of the wing. 
As this species approaches X. prunétramiela Clem., the only other 
described species of the genus, I have hesitated to describe it as a distinct 
species, but it differs so decidedly from Dr. Clemens’ description of 
prusiramiela that I conclude it must be a distinct species.

A. dorsimaculella. Ante p. 13. 
This species, for which I erected this genus, belongs to the Glyphip 
terygide near Glyphipteryx, and may be found to belong to Acrolepia

ADRASTEIA. 
A. quercifolidla. Ante p. 72, and v. 4, p. 200. 
The identity of this species with Psoricoptera gibbosclia St., suggested 
at p. 72 ante, was based upon Mr. Riley’s identification of the two, and 
upon a bad translation of a generic diagnosis from the German. Since 
the remarks at p. 72 were written, I have seen Mr. Stainton’s generic and 
specific diagnosis in Z#s. Brit., v. 3 (to which I had no access until this 
summer), and find that the most distinctive character there given and
