 parable to those of the squirrel and the chickadee in like circum- 

 stances than to those of any insect. Who ever heard of a dragon-

ENTOMOLOGY. 



Hagenius brevistvlus, Selys. 

 Referring to a note in The Ottawa Naturalist for May last 

 at page 37, m which it is stated that the nymph case of a larc^e 

 dragonfly was exhibited by me at one of the Entomological Branch 

 meetings, and that the species was not recognizable by .nv of the 

 members present, I may say that Dr. Fletcher has communicated 

 vu Professor J. G Needham about this pupa case and also sent 

 o him a drawing of the specimen, which has been identified as 

 belonging to ^a^enn^s trevistylus, Selys, the nvmph of which is 

 well figured in Professor Needham's valuable work on the 

 Aquatic Insects in the Adirondacks." (N. V. State Museum, 

 Wull. 47, 1901.) '
