This species differs from Adela bella Ohamb. and its synonyms in the decidedly 

 green color of the fore-wings, in the absence of golden scales on the apical surface, 

 and in the absence of transverse fasciaf orm markings on the apical third of the wing, 

 also in the longer antennas, of which a larger portion towards the base is tinged with 

 purple.

GENERAL NOTES. 



THE WHEAT SAW-FLY. 



Mr. W. Hague Harrington, in the February, 1890, number of the 

 Canadian Entomologist, records the collecting of Cephus pygmceus, 

 known in England as the " Corn Saw-fly," by sweeping in a meadow, 

 presumably near Ottawa, and also in a collection received from Mr. Van 



Duzee, collected near Buffalo, K. Y., 

 on the 9th and 11th of June, 1888. 

 Mr. Harrington's specimens were 

 taken in 1887. 



In this note Mr. Harrington does 

 not refer to Professor Comstock's 

 rearing of this insect from wheat 

 stalks in Ithaca, BT. Y., in 1888-'89, 

 which we have noted in a recent 

 number of Insect Life. The figure 

 which we give here is taken from 

 Curtis, and was originally made to 

 show the similarity with the method 

 of work and appearance of Phylloecus 

 integer, which bores in the young 

 shoots of willow, and which we 

 treated in No. 1 of Vol. I of Insect 

 Life. A comparison of this figure 

 with the one there given will show the 

 resemblance, and the republication 

 of this figure of Cephus will perhaps 

 assist other collectors in recognizing 

 it. The insect figured at / is the commonest European parasite — 

 Pachymerus calcitrator.
