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

 (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 9), which I found last 

 evening on a wall within the house. Several flocks of black
