THE CANADIAN NATURALIST. 



(Ephemera Cognata ?} of very large size, mottled with 

 black and yellow, having only two anal setae. In coming 

 up the river St. Lawrence last summer,, many of this fine 

 species flew on board below Quebec ; and the exuviae of the 

 pupse were floating down the river in myriads. Some pretty 

 beetles have occurred in my late researches : a small black 

 Cerambyx, with curved marks of bright yellow on the elytra ; 



(Clytus ?) a Buprestis, with rough elytra of a bistre 



brown ; the upper part of the abdomen brilliant green, only 

 visible when the elytra and wings are expanded ; the under 

 side coppery (Odontomis Trinervia) ; a Leptura, with the 

 fore part of the elytra scarlet, the rest black (Nephropis 

 Canadensis) ; I have observed, also, the Green Triangle 

 Dragonfly (Gomphus Vulgatissima}, the Greater Clouded 



Casefly, (Limnephilus ?) and the little Scorpion-fly 



(Panorpa Fasdata) ; the abdomen, in the males of this 

 genus, terminates in a large thi,pk knob, containing a pair of 

 pincers, like a crab's claw ; this it generally carries turned 

 up over its back. The brilliant little Green Rubytail 

 (Chrysis Cyanea) appears about the posts and walls of 

 houses ; the delicate Green Waterfly (Perla Cydippe) flies 

 about the margins of brooks and rivers ; and I have noticed 



a specimen of the Inlaid Casefly, (Phryganea ?) 



which appears to be a rarity. 



F We are drawing near the edge of the woods, as you 

 may perceive by the increasing light : we will go out, and 

 return home. 



C. Walking in the forest would be much more pleasant 

 if it were not so much encumbered with logs, roots, and 

 fallen trees. Sometimes we break our shins against them, 

 or stumble over them ; at another time we step on one, and 

 tread into a soft mass of dust and rubbish, instead of a hard 

 log, as it appeared.
