Carcafes of the plant-lice, void of motion, are 
often found on rofe-tree leaves; they are the ha¬ 
bitation of a fmall larva, which, after having eaten 
up the entrails, performs its metamorphofis under 
fhelter of the pellicule-which unfolds it, contrives 
itfelf a fmall circular outlet, and fallies forth into 
the open air. 
There are ichneumons in the woods, who dare 
attack fpiders. 
Others, deftitute of*wings, (females) depofit their 
eggs in fpider’s nefts. 
The ichneumon of the bedeguar, (or fweet-briar 
fpunge) and that of the rofe tree, perhaps, only 
depofit their eggs in thefe places, becaufe they find 
other infecls on which they feed. 
The genus might properly be termed cannibals* 
In 1795 thefe infers happened to -abound; they 
entered rooms (allured by the light) in the evening, 
and frequently exercifed their flings with great feve~

Many fpecies are common in England; they are 
chiefly found in woods and hedges. Their larvae feed 
upon dead infefts, in the bodies of which they are 
produced from the egg. Some
