THE 
CANADIAN 
NATURALIST. 
C Ephemera Cognata ?J of very large size^ mottled with 
black and yellow^ having only two anal setse. In coming 
up the river St. Lawrence last summer^ many of this fine 
species flew on board below Quebec ; and the exuvice of the 
pupse were floating down the river in myriads. Some pretty 
beetles have occurred in my late researches : a small black 
Ceramhyx^ with curved marks of bright yellow on the elytra ; 
( Clytus ? J 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 Trinerma ) ; a Leptura, with the 
fore part of the elytra scarlet, the rest black ( Nephropis 
Canadensis ) ; I have observed, also, the Green Triangle 
Dragonfly f Go^nphus Vulgatissima), the Greater Clouded 
Casefly, ( Limnephilus ? ) and the little Scorpion-fly 
( Fanorpa Fasciata ) ; the abdomen, in the males of this 
genus, terminates in a large thick 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 
f 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 f J 
which appears to be a rarity. 
jP. — 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.
