232 THE CANADIAN NATURALIST. 
/ GIANT WATER- FLY. 
(Pteronarcys Regalis.) 
F, — l have taken a very large species (Vteronarcys Pro- 
teus ) at Sherbrooke^ near the junction of the Magog River 
v^ith the St. Francis ; but I have not any specimens now. 
It is notj however, near so large as yours, but resembles it 
in colour. 
C. — A handsome Buprestis ( Stenuris Divaricata J 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 Rusticorum),
