324 THE CANADIAN NATUHALIST. 
nest, which we found in the hay field in mowing time^ I 
found the wasps benumbed and unable to fly^ as it was one 
of those cold frosty days, a week or two ago. 
F, ' — I founds a few days since^ in a cavity in a piece of 
timber^ several of the thimble-like cases forming the nest of 
the Leaf-cutting Bee ( Apis Centuncularis ) ; they were 
made of round pieces cut out of rose leaves^ most snugly 
compacted together ; the thimbles fitting each into the other^

Froghoppers f Tettigonia Quadrivittata ), hopping about right

(Tettigonia Mollipes ), Here is also one of those fan-wing-

reaching to the anus, whose delicate net-work wings reflect 
every tint of the rainbow ( Acrydium Ornatum ). And 
this reminds me of another very delicate insect, the little 
Pearl-fly ( Hemerobius Fasciatus ? ), which I found last 
evening on a wall within the house. Several flocks of black
