cratcegella, and in L. Hageni F. & B., represented by a long dorsal streak 

 placed immediately behind the apex of the median basal streak, and 

 curving to a point near the middle of the wing, dark margined, and not 

 confluent with the basal streak. This is the most striking difference 

 between the species except in size ( L. Hageni is larger than L. cratcegella, 

 which is larger than this species). In the apical part of the wing is a 

 median dark brown streak extending to the apex. In cratcegella this streak 

 is much longer, beginning at the first costal streak and connected with 

 the dark margin of all the streaks ; in this species it begins behind the 

 second costal streak ; and in Hageni it is represented only by a small 

 circular apical spot. Cilia? white with a dark brown hinder marginal line 

 at their base ; in this respect it resembles cratcegella, while Hageni has the 

 tips of the costal ciliae brown and a distinct brown " hook " radiating 

 from the apex through the ciliae. In this species and in cratczgella the 

 space at the base of the wing between the median and the dorsal basal 

 streaks is of the general color, except that the color gradually deepens 

 towards the apex, while in Hageni the whole dorsal half of the base of 

 the wing is white, so that there is no distinction between the median and 

 dorsal basal streaks ; the white, however, extends farther along the middle 

 of the wing than it does along the dorsal margin. Hind wings in this 

 species pale silvery gray, with ciliae of nearly the same hue. Fore legs 

 white with the tibiae and tarsi marked on their anterior surfaces with red- 

 dish saffron. The fourth dorsal streak is small in this species and in 

 cratcegella; indeed, in the latter it is sometimes obsolete. It is distinct in 

 Hageni, and I am not sure but that a fifth is also there indicated by its 

 small dark margin. This species is nearer to cratcegella than either is to 

 Hageni. The larva of cratcegella feeds on Crataegus and allied genera ; 

 that of Hageni, according to Prof. Frey, on Oak, and from the locality in 

 which I took the single specimen of this species I suspect that it also 

 feeds on Oak. 



Gracilaria pnrpuriella Cham. 



This species was originally described from a few bred specimens and 

 seemed to be distinct from the European G. stigtnatella. But a larger 

 collection induces me to believe that on a comparison of specimens they 

 will be found to be the same species.
