THE 
CANADIAN 
NATURALIST. 
Black Sirex of Newfoundland (Sirex Juvencus), Then, in 
the evening, returning after dusk, I found among the grass 
by the road- side, a flat grub, much resembling an Oniscus ; 
from which proceeded a spark of greenish light, by which I 
discovered it. I suppose it was the larva of our summer 
fire-fly ( hampyris Corusca ). 
C, — Your speaking of fire-flies reminds me of a small 
Fulgora that I have lately taken f Otiocerus — ? J ; our 
specimen^ however, has none of that luminous radiance 
which characterises the fine foreign species, the Peruvian and 
Chinese Lantern-flies. It is a pretty little insect ; the head 
is curiously elongated, the wings are very delicate, trans- 
parent whitish^ with a pink stripe through them ; but "vyhat 
is most remarkable, the antennae are triple on each side. 
F, — The ugly Black Crickets f Acheta Campesiris ) now 
begin to swarm about the fields, especially under stones : 
except in colour, they strikingly resemble the house cricket. 
We find maliy little frog-hoppers, with prominent thorax ; 
but here is a singular species which I have just caught^ 
( Memhracis Belligera ? ) having the thorax projecting like 
a curved horn, far over the head. — How wonderful the 
variety in form alone, which appears in insects ! what 
strange shapes^ endlessly diversified^, we see every day, 
which would command our constant admiration, but that 
their minuteness makes us in some measure blind to their pe- 
culiarities ! Yet no variation of form is made, we may be 
assured, without some determinate and wise purpose, not 
only proposed, but effected.
