PSYIvUD NOTES. 217 



longer and the smaller of the two terminal tooth-like projections 

 is at a slightly greater distance from the tip in mibifera and the 

 female genital segment is relatively longer, the lower plate being 

 subequal to the two preceding segments while in polygoni it is 

 subequal to but the one preceding segment. 



The wing of nuhifera is broader than that of polygoni and 

 the cloudiness of the wings is differently disposed. Lot 1348- 

 Sub 48. Figure 369. 



■ Aphalara rumicis Mally. 



Lot 1 341 Sub 6 was collected at St. Louis, Mo., Sept. 22,. 

 191 1, by Mr. J. T. Monell who says of them; — "On Runiex, 

 the broad leaved common one, I found a colony curling the 

 leaves longitudinally into a pseudogall which turned scarlet — 

 from these I reared a few which I mail to you." 



This species is closely allied to those developing on Polygo- 

 num and Sisymbrium, Mally's description and figures definitely 

 and sufficiently characterize the nymphs. The specific charac- 

 ters of the wing and forceps are shown in figures 372 and 377..

Aphalara picfa Zetterstedt. 



A large species with wing 3.55 mm. long in the Colorado- 

 collection I take to be picta as figured by Crawford (1911). 

 Figures 380, and 388 represent the forceps and the caudal 

 segment of the female. Lot 1348 Sub 29.

Aphalara fascipcnnis sp. nov. 



Collections from Canada and New York are at hand of a 

 beautiful species which comes close to picta. The genitalia of 

 both sexes resemble picta closely. The abdomen of the male is
