TOO THE CANADIAN ENTOMOLOGIST. 



notes from wollaston, mass. 

 Dear Sir, — 



During the season of 1878 I have found at this place, situated within 



two miles of the limits of Boston, some species of butterflies which are 



seldom found in this vicinity. On the 8th of October I obtained a nice 



specimen of C. eurytheme, which had probably left the chrysalis,but a short 



time before. It was flying in a meadow in company with great numbers 



of C. philodice. The orange-colored tinge of the wings is lighter than on 



specimens taken farther south. If I am rightly informed, this is the first 



instance of the capture of this species in this vicinity. On the 29th of 



June a specimen of L. arthcmis was taken, and another July 3rd ; both 



specimens had just emerged from the chrysalis. The' larvae evidently fed 



on the Qne?rus alba, which was very abundant in that locality. A number 



of specimens of ^. avnia have been taken here within the last three 



years, in the month of August or early in September. Ccenia seems to be 



rather widely distributed through Massachusetts, and though quite rare, I 



have found it more common in this vicinity than elsewhere. This species 



seems to prefer meadows and lowlands to higher ground, and is quite fond 



of the flowers of the Golden-rod.

Dear Sir, — 



In answer to numerous enquiries and a letter in No. 3, all in reference 

 to my letter in No. 2, page 39, regarding the Larvae of a Cossus, allow 

 me to state that I did not write that letter with a view to publication, but 

 have since corresponded freely with some good authorities on the subject, 

 and am quite sure this Cossus is a new one, much larger th^an centerensis 

 or robinice. I also learned that the rearing of Cossus in dead wood is 

 likely not to be crowned with success ; they require living wood in which 

 sap rises, etc. I have since obtained Cossus larvae of large size in willow 

 saplings ; these I have now growing in large flower-pots, and am likely to 

 be successful with them. I have also found five more trees close to my 

 place of business, literally perforated with this Poplar Cossus. I have 

 also made accurate drawings of this larva and sent them to Dr. Bailey, of 

 Albany, and .in due time further articles will appear, likely with illustra- 

 tions, on the Cossus generally, by his able pen.
