all the sugared trees, I captured about a dozeu specimens. 

 I saw several fly down from overhead or from the tops of 

 the trees ; and this coupled Avith the fact that other than the 

 above I have seen but one specimen near the ground, and 

 that one flying upwards, leads me to infer that the species 

 though comparatively common, lives among the tops of the 

 trees (hickories and walnuts) and rarely comes near enough 

 to the ground to be captured unless allured by some bait. 



One of my correspondents in Ohio to whom I mentioned 

 the fact told me he had captured hundreds of Puyyurlcenus 

 hum er alls Fab. imr. humeraUs on sugar-cane stumps. The 

 excessive love for sugar thus shown in widely separated 

 localities by the type and variety strikes me as quite a 

 curious incident. I propose to further investigate this 

 matter durino- the comino: season. 



NOTES ON THE LARVAE OF CERTAIN HETE- 

 ROCEROUS LEPWOPTERA.

As is well known, the early brood of the Codling-moth, 

 Carpocapsa pomonelhu pass through all their changes in a 

 comparatively short period, while the late brood do not 

 produce the imago till the next spring. It is not so well 

 known, probably, that the late brood remain in the larval 

 state till spring. From some observations made the past 

 season it seems certain that this is the case. While looking 

 after Canker-worm moths, November 29, 1881, I found a 

 cocoon of a Codling-moth under a piece of bark on an apple 

 tree ; and on opening it the larva was found to be unchanged. 

 Another cocoon was found April 25, 1882, and on exam- 

 ination the larva in this was still unchanged. Just how
