on oak, this ma}^ eventually prove the food plant of the species. 

 Of Argi/resthia anJereggiella Duponchel, I know no American speci- 

 mens, and it should properly be excluded from our American faunal 

 list, as its record seems to be made only on misidentified specimens. 

 There is, however, a possibility that the species may have been or will 

 l)c introduced, and 1 give the figure of the wing from authentic Euro- 

 pean sp«^cimens (Plate IV. tig. 1<») for comparison with oreasella. 



ARGYRESTHIA INSCRIPTELLA, new species. 

 Plate IV, lig. n. 



Palpi and face light golden; head pure white; antenn;© white, with 

 brown annulations. Thorax white. Forewings silvery white, with 

 dark golden or bronze-brown markings, as follows: Costal edge from 

 base to the middle of the wing suffused with light brown; from the 

 middle of the costa a broad, inwardly oblique, dark golden-brown 

 fascia, with two or three small white notches on the costal edge; entire 

 apical third strongly overlaid with dark golden-brown scales, except 

 for three costal white dashes, two dorsal and several minute apical 

 white dots. The apical dark part of the wing- is separated from the 

 central fascia by a larg-e triangular pure white spot, which rests with 

 one side on the dorsal edge and from the opposite upper corner emits 

 a narrow line upward to a white costal dash. Hindwings rather dark 

 fuscous. Legs silvery white, with tips of all joints brown. Forewings 

 with veins T and 8 stalked.

Shining silvery-white, each joint of the antennte (except the basal 

 one) dotted above with dark brown. Primaries with a blackish or 

 dark-brown, shining, almost triangular spot at the apex, with three 

 pale and indistinct brownish costal streaks before it; the first of these 

 streaks is the shortest and most indistinct and is placed at the begin- 

 ning of the cilia. The second is a little more distinct and sometimes 

 extends entirely across the wing and the third one always does so after 

 dividing into two branches just before the apical spot. These streaks 

 are usually more or less interrupted and sometimes spread over the 

 apex, so that it might perhaps be more correctly described as dusted
