cut and that portion of the margin of the leaf included between 

 the two oblique cuts, and bearing on its edge the small case, which 

 usually bends toward one side. If the serrations of the leaf mar- 

 gin are small, there may be three or four along this edge. The 

 lower edge of the case is formed from the long oblique cut, and 

 the real apex is at the junction of this cut with the margin of the 

 leaf. These relations will perhaps be made clearer by the accom- 

 panying figure. Length of case from mouth to apex : 5-6 mm. 

 The resemblance of the small case to a tail is very striking, and 

 the notches described by Clemens are in reality due to the manner 

 of attachment of this small case to the upper edge of the large 

 case. 



In the spring the "tail" is soon lost, but its former position is 

 often easily determined by the short light streak of ocherous silk 

 on the ridge along the upper edge of the case. In the spring the 

 case becomes more rounded out and less flattened than when first 

 made. 



The imagoes appeared June 3d and 4th. Coleophora cerasi 

 vorella Packard, seems to resemble this species closely. If the 

 characters given in the meager description can be relied on at all, 

 the whitish gray antennae, annulate with white, will distinguish it 

 from C. prunieUa, in which the contrasting black and white rings 

 on the antennae are very conspicuous. C. priiniella also bears con- 

 siderable resemblance to C. Hetcherella Fern., but is distinguished 

 from it by the conspicuously annulated antennae, as well as by 

 the larger size and browner color. A third closely related species 

 is C. occidentis, Zeller, but the case as noted by Zeller is quite dif- 

 ferent. To the other cherry and apple feeding species, C. mali- 

 vorella Riley, C. lapidicomis Wlsm., and the plum- feeding species 

 described below, it has no resemblance whatever. 



There is a group of closely related species comprising Coleo- 

 phora limosipennella Dup., C. caryaefoliella Clem., C. ostryae 

 Clem., and a fourth, a plum-feeder, described below, all charac- 

 terized by the ocherous or reddish brown color of the wings and 

 the whitish costal streak from the base. Of these, C. Uinosipen-
