posit its eggs. It is very unfortunate, and tends greatly to mislead 
and confuse those who are not conversant with this branch of 
science, that in this country, the name weevil, which belongs to 
these long-snouted beetles only, is currently applied to insects so 
widely different from them as are the wheat midge or wheat fly 
and the Angoumois moth. Two of these Algiers weevils, it will 
be seen, pertain to the genus cleonus, one of the species of which 
(C. Linarice) forms gall-like excrescences upon the roots of the 
Linaria vulgaris, the snap-dragon or “butter and eggs,” as it is 
most commonly designated in this section of the country. This 
plant was introduced into flower-gardens in this vicinity about 
twenty-five years ago, and ha3 now become by far the most formi¬ 
dable weed with which we have to contend—taking entire posses¬ 
sion of acres of our best fields and setting at defiance all except the 
most persevering and laborious attempts to exterminate it. We 
have often thought that if some of the insects of Europe which prey 
upon this plant, could be here introduced, it might prove by far 
the most economical and effectual mode of reducing this “ officious 
foreigner” to its appropriate limits. 
The thirteen succeeding species, (No. 101-113,) pertain to the 
family of long horned beetles, (Cerambysid.e,) insects generally 
of a slender, elegant form and beautifully ornamented in their 
colors. The larvae of most of them, however, are pernicious to 
timber and fruit-trees, boring holes in the solid wood. Examples 
of this family of insects are tolerably well known in this country 
being the borers in our apple, locust, maple and other trees. 
The wasps and bees (No. 114-118,) are insects udiose habits are 
so well known as to call for no remarks in this hasty review. 
The remaining species (No. 119,128-136,) pertain to different 
families of the group of butteiflies, each species of which, in its 
larvae state, feeds upon the leaves of some one or more plants. 
Of these, the Colias edusa will be noticed as very.like the common 
yellow butterfly of our meadows and which gathers in such num¬ 
bers upon the muddy margins of pools of water. Its larvae in 
common with those of the other species of this genus, subsists
