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. pruntramiella 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 

 pruniramiella that I conclude it must be a distinct species. 



ARGIOPE. 



A. dorsimaculetta. Ante p. ij. 



This species, for which I erected this genus, belongs to the Glyphip 

 terygidce near Glyphipteryx, and may be found to belong to Acrolepia 

 Curt. 



ADRASTEIA. 



A. quercifoliella. Ante p. 72, and v. 4, p. 206. 



The identity of this species with Psoricoptera gibbosdla 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 Ins. Brit., v. 3 (to which I had no access until this 

 summer), and find that the most distinctive character there given and
