156 THE CANADIAN ENTOMOLOGIST. 
Thus if we take the mammalia as our starting point, we shall find | 
that the carnivora are represented among the birds by the raptores, 
among the reptiles by the crocodiles and serpents, among the insects by 
the predaceous beetles, ichneumons, and dragon-flies, among the annulosa 
by the spiders, crabs, lobsters, &c., among the mollusks by the cuttle-fish 
and by some of the gastropods and a few brachiopods, and among the 
radiates by the sea-urchins, star-fish, sea-anemones, and many of the 
animalculæ. | 
Confining our observation to the parallelism between the mammalia 
and the birds on the one hand, and the insects on the other, we find that 
the carnivorous mammals are well represented among the Coleoptera as 
follows :—The felidæ, the typical carnivora, by the Cicindelidæ, whose 
resemblance is acknowledged in their vernacular name of “ tiger-beetles.” 
The canidæ, dogs, wolves, foxes, are fitly represented by the Carabide, 
the weasel tribe by the Staphylinidæ, and the hyænas and vultures by the 
Silphidæ; while the marine carnivora, the seals and whales, find their 
representatives in the Dytiscidæ and Hydroidx; and the various species 
of raptorial birds are no less fittingly typified by the Libellulidz, ichneu- 
mon-flies, sphexes, and the predaceous wasps and hornets ; not forgetting 
the ants, which have a highly developed carnivorous organization. 
I shall not follow out in detail the obvious resemblances that may be 
observed between the pachydermatous animals and the Lucanidz and 
other dendrophagous insects, as well as between the bovine, equine, and 
ovine tribes, and the gallinaceous and cursorial birds on the one hand, 
and part of the Scarabeidæ and Chrysomelidæ, and most of the Orthoptera 
on the other; or those not less remarkable that exist between the goat, 
deer, and, antelope families, and the Cerambyx, Clytus, and Leptura 
genera. 
If the hints I have thrown out should induce some of my younger 
entomological brethren to study more closely the relation of the Insects 
to the other members of the Animal Kingdom, my intention will be 
amply fulfilled. :
