offers it to Prof. Kellicott for examination ami study. The pupae in this 

 genus afford excellent specific characters. 



Prof. Riley says Mr. Koebele last fall found in N. II. a larva boring 

 in birch, which he thought was a Cossid. This died, or at least has not 

 emerged, and as far as he recollects agreed very well with Dr. Kellicott's 

 description. However, some examination had been made, and some 

 discussion had been had with the result that it was doubtful whether the 

 larva was Cossid, or whether it was not that of a Zeuzera or an Aegeria. 

 He simply suggests this as a possibility as the larva seems to agree very 

 well with Dr. Kellicott's account. 



Dr. Kellicott says he is very sure it is not an Aegeria but a Cossus. 

 He further mentions that he has found querciperda at Buffalo, in dry red 

 oak. At first he thought them small specimens of C. robifiice. 



Prof. Lintner hopes that Dr. Kellicott will continue his experiments 

 and observations on this interesting group. 



Prof. Riley then gave some 



NOTES ON THE PRINCIPAL INJURIOUS INSECTS 

 OF THE YEAR. 



We are aware that almost every year is characterized by some un- 

 usual prevalence of destructive insects, not previously observed in any 

 such numbers. Examples were last year Pulvinaria innumerabilis and 

 Agrotis fennica. A glanee at the entomological events of the present 

 season shows a comparative scarcity of such phenomena so far as noxi- 

 ous species are concerned and I can recall but few characteristic of the 

 year. One worthy of mention is Agrotis messoria found at Goshen, 

 N. Y., destructive to the onion. This had previously been known as 

 destructive to vegetation, but principally to fruit trees by cutting out the 

 buds in early spring; hence the habit noticed this summer has been ex- 

 ceptional. Another species, belonging to the Coleoptera, Anihonomus 

 musculus, attracted considerable attention in the strawberry fields, cm 

 Staten Island, N. Y. This habit of the species is not new, because I had 

 noticed it in Missouri many years ago, but its abundance and destructive- 

 ness were phenomenal. As is usual, where a great abundance of a form 

 is collected, the species was found to have two names, and there is some 

 doubt as to what the destructive species really is. 



Another Lepidopterous insect, Eurycreon ranialis, a Pyralid, is 

 worthy of mention as a conspicuously injurious insect in the South- 

 western States. It is astonishing what an amount of injury this insect 

 has done, and the agricultural papers have been full of accounts of this 

 "web worm'', as this insect has popularly dubbed. This larval first 

 found in 1S67, in Western States, and in Kansas in 1S73, common on
