THE CANADIAN NATURALIST. 



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 found, 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, 

 and each containing a maggot. 



C. Would they have produced the perfect bee this 

 season ? 



F. No, I should think not ; but it is probable, as the 

 maggots were considerably grown, they would have gone into

 imago early in spring. 



C. I have taken some new moths lately, particularly 

 a beautiful Geometra, and some pretty Noctuce. 



F. A friend of mine told me that he observed, about 

 five days ago, in a potato field, a young snake of the com-

inches long, and as thick as a tobacco pipe ; it was very ac-

 met with any myself for many weeks. 



C. These heaps of fallen maple leaves are quite teeming 

 with life : here are great numbers of the little crimson-striped 

 Froghoppers (Tettigonia Quadrivittata ) > hopping about right 

 merrily ; and some of a green species, still more minute 

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

 ed locusts, with the thorax elongated into a sharp spine, 

 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
