GIANT WATER- FLY. 



(Pteronarcys Regidis.) 



F. I have taken a very large species (Pteronarcys Pro- 

 teus) at Sherbrooke, near the junction of the Magog River 

 with the St. Francis ; but I have not any specimens now. 

 It is not, however, near so large as yours, but resembles it 

 in colour. 



C. A handsome Buprestis (Stenuris Divaricata) is 

 now occasionally seen ; chiefly on trunks of trees, rails of 

 the fence, &c. The Buprestis, I believe, inhabits wood in 

 its earlier stages, which accounts for the perfect beetle's fre- 

 quenting such situations, having, perhaps, just emerged into 

 daylight from its long imprisonment ; or, perhaps reconnoi- 

 tring for the purpose of laying eggs, for a new generation. 

 This one has the upper parts metallic brown, the under parts 

 shining coppery ; and the elytra, which are sculptured, ter- 

 minate in lengthened points or tails. I have taken a larger 

 species (Anoplis RusticorumJ.
