CORRESPONDENCE. 



Dear Sir, — While on a visit to the neighborhood of Brantford for a 

 couple of weeks in the latter part of July, I came upon an elm stump with 

 the bark curled loosely round it. On pulling back the bark I saw a 

 Calopteron reticulatum fresh and bright. The form, with the front part 

 of the wing covers, all yellow ; the hind part, blue black. There was also 

 one just emerged. It was a chalky white ail over ; the front part with a 

 yellowish tinge, the hind part with a bluish tinge. On examining the 

 stump and inside the bark I found clusters of pupse, remarkable in the 

 regular formation of the cluster. The pupae were in straight rows, close, 

 side by side, the row above half lapped over the row below it, each pupa 

 of the upper row placed exactly between the two below it. One cluster 

 was formed thus : — The lower row four ; the second row four, one pro- 

 jecting to the left ; the third row three ; the fourth row two ; the fifth row 

 two, one projecting to the right. Another cluster had four in the lower 

 row ; five in the second, two projecting to the left ; four in the third ; 

 three in the fourth, and finished there. Then there were twos and threes 

 in different places, with one by itself. I visited them often to watch their 

 appearance. Sluggishness seemed to be their principal characteristic. 

 Slow in withdrawing from the pupa case ; slow in obtaining color and 

 consistency, and slow to go off on the wing. ' True, the weather was cool 

 and showery, which would tend to increase their slowness. They did not 

 come out in order of time according to the rows, but came from the upper 

 and lower ones indiscriminately ; but every one of them was the same
