Of these species I have only been able to examine the neuration of 

 aetheria and patruelis, from want of material. Three of them, patula, 

 elegantiila and arizona, are not represented in my collection. Aetheria 

 and patruelis agree in having no accessory cell, but differ by veins 8 and 

 7 being separate in patruelis. Whereas in aetheria 8 springs from 7 and 

 9 from 8, in patruelis 9 springs from 8 and 10 from 9. Prof. Zeller seems 

 somewhat uncertain as to whether mundula can remain under Thalpochares, 

 and I am equally so with regard to orba until I can obtain more material 

 from which to study the neuration, which is a guide in this and allied 

 genera. 



CORRESPONDENCE. 

 Dear Sir, — 



It may be of interest to note the occurrence of the following species : 

 In July last I found the pupa skins of a Cossus protruding from the trunks 

 of Poplar trees at Corunna, Mich. One of these skins sent to Dr. J. A. 

 Lintner was said by him to be identical with that of C. eenlerensis (vol. 

 xi.-i). The exact locality is a grove of Poplars divided by the branch 

 railway to the coal mine, a short distance before the river is reached. I 

 obtained a half dozen of these shells in less than an hour's search. The 

 moth should be sought from the 1st to the 15th of June. 



Nephopteryx Zimniermaiii I found in the same locality common 

 enough, both in cultivated and forest pines ; it was especially abundant 

 and destructive to small pines and spruces ornamenting the cemetery. I 

 took eight pupae from the trunk of one of these spruces ; these trees had 

 been visited by the axe. I also found the larva? in force at Gowanda 

 N. Y., early in June.
