iiig to a difiereut species altogetlier (quadripunctella), and do agree 

 with a specimen in tlie National Museum collection, bearing the 

 label "0. prunivorella Ch. geminatella Pack, bred from apple." 

 The authenticity of this specimen is in doubt. I have not seen the 

 type of geminatella. To judge by the description it is the same as 

 primivarella Ch. Nevertheless, I have serious doubts on this point, 

 and while positive as to the identity o'l prunivorella, feel compelled 

 to assign geminatella as a doubtful synonym of the former. 



<>. quadripunctella Clem.— Palpi sordid white, dusted with fuscous, 

 second joiut witli dark apical spot externally, third joint broadly annulate with 

 blackish fuscous. Face fuscous, mixed with gray, tufts dark drown, occiput and 

 thorax grayish-white, latter speckled with fuscous. Forewings grayish-fuscous, 

 with feeble purplish lustre and scattered white scales; seven or eight whitish 

 costal strife, approximately equidistant and increasing in length aud distinctness 

 towards the apex, where they almost reach the dorsal margin ; apical spot well 

 marked; plical spots in form of a subtriangular dash, extending but little into 

 the subplical space, latter rather conspicuously white, with scattered fuscous 

 specks. Cilia whitish, basal part and below the apex fuscous; three entire fus- 

 cous lines. Expanse 8.5-9.5 mm. ; .34-. 38 inch.

I entertain not the least doubt that this is the species of which 

 Dr. Clemens described the larva and food- plant only. The former 

 is pale yellowish, head and first segment each with a transverse row 

 of black dots. I have bred specimens from Pyrus arbutifolia 

 (choke berry), which is closely allied to and generally mistaken for 

 Amelanchier canadensis. I have also bred it from apple. A speci- 

 men from the National Museum collection aud referred to under A. 

 primivarella belongs here. 



A specimen received from the National Museum collection, bred 

 from quince (Cydania vulgaris), while scarcely distinguishable from 

 the species under consideration, I feel restrained to consider at least 

 as a variety, which eventually may prove to be specific. 



Var. albitaciella. 



DitFers from typical specimens by the grayish-white head, face 

 silvery white, tufts light yellowish fuscous. The larva also, accord- 

 ing to a note on the label, differs " Larva difl^ers from that on wild 

 cherry, no black s})ots on thorax or head." This latter observation 

 alone, if correct, would prove it a genuine species.
