THE CANADIAN ENTOMOLOGIST. 19 



to in the various reports, with brief explanatory references. Following 

 this we have a list of insects to a greater or less degree beneficial by 

 destroying noxious insects, a paragraph on other agencies referred to as 

 useful in the destruction of insects, concluding with a list occupying 21 

 pages, also alphabetically arranged, of vegetable and animal substances 

 injured or destroyed by insects. 



The compilation of this work has been attended with much labor, and 

 furnishes another evidence of the untiring industry of the author. It will 

 prove an invaluable help to all who desire to consult the pages of these 

 reports for information on Entomological subjects, and it is much to be 

 regretted that the edition is not sufficiently large to make it accessible to 

 all who may be interested in Entomology. 



NOTE ON THE STRUCTURE OF NEPHOPTERYX ZIM- 



MERMANI. 



BY A. R. GROTE, BUFFALO, N. Y. 



The following note on the structure of Zimmermani is taken from a 

 MS. paper on the N. Am. Phycidce which I am preparing for publication. 

 I would be glad of more material in this group from any correspondents. 



" Pinipestis (sub-gen. nov.). 



Maxillary palpi alike in both sexes, concealed by the porrect labial 

 palpi, which have the third article erect and exceed the front. Ocelli 

 present. Male antennae very slightly bent at base, where they show slight 

 continuous scale-tufts ; ciliate beneath. Fore wings with veins 4 and 5 

 running close together at base ; these veins are seen to have a separate 

 origin, 5 on the cross-vein close to 4, divaricating at one-third from base. 

 Hind wings 8-veined ; vein 5 running close to 4 at base, but separate and 

 continuous with the discal cross-vein. Head behind with a thick trans- 

 verse ridge of scales ; clypeus with a bunch-like projection of scales 

 centrally." 



I have corrected my former statement as to vein 5, having made a 

 fresh observation under a i-inch objective. This correction will not allow 

 of the species remaining under the sub-genus Dioryctria as defined by 

 Heineman, and presumably establishes Pin. Zimmermani as distinct from 

 the European Dior, abiete/la.
