294 AMERICAN LEPIDOPTERA. 



Hah. — Penna. (Hazletoii). 



The single specimen which serves as type of this species, was bred 

 by the writer from thorn (C'ratwgus) in 1899. The fine, yet very 

 distinct and nearly alike costal striae are not seen in any other spe- 

 cies known to me. Unfortunately the cilia are defective and I can- 

 not discern whether they are tipped with dark fuscous or not, 

 around the apex. It is therefore placed here tentatively, as it 

 resembles more the two preceding species than any others. 



O. anglicella Snt. — Palpi white, third joint broadly annulate with fus- 

 cous. Head yellowish-white, tufts brown. Thorax sordid white. Forewings 

 dark gray, with numerous costal striae, more distinct towards the apex ; a white 

 spot at end of cell, preceded by a fuscous spot. Plical spots moderately large, 

 not attaining the dorsal margin ; subplical space rather densely speckled with 

 fuscous. Basal portion of cilia pale fuscous, remainder grayish-white, third line 

 entire, except just before the apex where it is interrupted. Expanse 9-11 mm. 

 (Meyrick); .36-.44 inch. 



Hab. — Europe ; New England States. 



I cite this species here on the authority of Lord Walsingham.* 

 A well authenticated European specimen of this species is before 

 me, but have not seen one from within our own faunal limits. 



The third ciliary line, although complete, extends to but not 

 around the apex, thus distinguishing it from any others of our 

 North American species. The larva lives on Cratcegus (hawthorn), 

 also occasionally, according to Meyrick, on Frayaria (strawberry). 



O. priiiiivorella Ch. — Palpi white, third joint with a wide, dark fuscous 

 band, whicli leaves only the base and extreme apex white. Head grayish fus- 

 cous, tufts darker. Thorax grayish fuscous. Forewings dark brown, intermixed, 

 especially in basal half with grayish-purple; costal striae rather obscure, more 

 distinct on the costa, the outer four or five stria? extending nearly to the dorsal 

 margin ; interstria! spaces conspicuously darker; subplical sjiace not intermixed 

 with white and scarcely paler than rest of wing; plical spots almost obsolete, a 

 patch of blackish, semi-erect scales about middle of dorsal margin. Expanse 

 8-9 mm. ; .32-.36 inch. 



Hab. — Middle and Northern States of Atlantic slope. 



Larva in mine on underside of leaf of wild cherry and apple. 



Two specimens in my collection, received a number of years ago 

 from Miss Murtfeldt, agree with specimens bred by the writer from 

 wild cherry, and have the dorsal patch of semi-erect scales, espe- 

 cially well developed ; they do not, however, agree with any speci- 

 mens of the genus which I have bred from apple, the latter helong-
