Argyresthia freyella sp. n. 



{^Antenna;, missing.] 



Head and thorax, white. 



Fore wings, shining, mottled with silvery-white and golden-yellow ; the silvery-white 

 markings consist of a spot at the middle of the base, two pairs of wide, nearly 

 opposite, outwardly oblique, costal and dorsal streaks, the dorsal commencing a 

 little before the costal and blending with the latter about the middle of the wing; 

 beyond the outer costal streak are three more small costal spots, the first of which 

 la diiihsed towards the middle of the wing, tending to blend with the angle formed 

 by the preceding pair ; there is also a faint indication of dorsal spots at the base 

 of the cilia; there is a distinct triangular black dot at the extreme apex; cilia, 

 golden-yellow, whitish at their bases. Underside, pale, brassy-ochreous. 



Hind-wings very pale grayish with an ochreous tinge throughout the cilia. 



Abdomen, grayish, ochreous at the base. 



Legs, sordid whitish, with very faintly speckled tarsal joints.

This species is described from a single specimen in the Frey collec 

 tioii. The white head and thorax at once distinguish this species from 

 cupressella, which it greatly resembles in the disposition of its markings, 

 although it differs in the paler golden-yellow of its fore-wings. The 

 markings are so ill-defined, tending so much to blend into each other, 

 that the above description can only be taken as an attempted indication 

 of their general pattern. It is extremely probable that this is a speci- 

 men of the species referred to by Zeller [Ver. Z-b., Ges. Wien xxiii, 106 

 (1873)] under the name abdominaUs Z., but it is in sufficiently good con- 

 dition to show that the pattern and markings are quite different 

 from those of the European species ; indeed it is more nearly allied to 

 cupressella than to abdominaUs, although it may be regarded as inter- 

 mediate between them. In abdominalis the white ground color of the 

 wings is cleauer aud brighter and decidedly predominates, whereas in 

 freyella the wings are much more golden although the costal and dor- 

 sal oblique streaks are wider, nor indeed are these streaks to be found 

 in the same position in the European form. I have no hesitation in re- 

 gar<ling freyella as abundantly distinct. The pale markings are de- 

 cidedly not dark margined in either of these species, nor is there any 

 fus(;ous sprinkling. In these respects they differ from quercicolella 

 Chamb., and this species must therefore be regarded as distinct. Cham- 

 bers's identification (Can. Ent. xi, 144, 1879) notwithstanding. 



Argyresthia plicipunctella sp. n. 



Antemue, annulate with white and brownish-gray. 



Palpi, sordid whitish. 



Head and thorax, white. 



Fore wings, white, densely dusted above the fold with grayish-brown ; a marginal 

 line of dark brownish runs around the apex at the base of the cilia, contiguous 

 to which are two or three ill-defined brownish spots; beneath the basal portion 

 of the fold is a series of distinct grayish-brown spots; at the outer third of the 

 fold is a strong brownish spot lying in the fold itself, distinctly separated from
