THE ORDER OF COEEOPTERA. 
We will add a few additional notes upon those sub families which 
are most common or most numerous in species, and which will therefore 
be most likely to occur to the student: 
Section 1st. Brevirostrcs. 
Sub-family ITHYCERIDES. 
This sub-family has been formed to .receive 
a single N. American species, the Ithycerus no'vebora- 
eensis, or New York weevil, a comparatively large 
and rather common species which is sometimes con- 
siderably injurious toapple trees by devouring the 
buds and bark of young twigs. It differs from 
all other short-snouted weevils in not having the 
antennae elbowed. The rostrum is robust, and the 
scrobes very short and oblique. It is a bulky insect 
five or six-tenths of an inch long, of a gray color, 
with a few.'small black spots on the wing-covers. 
The name is derived from the Greek tOu<; straight, 
Ithycerus novebobacen- and xepas antenme. 
818, Forster : — a, slit’made in 
oak twig by female for de- 
positing lier eggs ; b, larvie; 
c, beetle — after Itiley. 
Sub-family CLEONTDES. 
In these the antennas are but slightly elbowed, thus forming a trans- 
itional group from the Ithycerides to those which follow. The rostrum 
is rather robust and angular or carinated above, and longer than the 
head ; the scrobes are linear and deep, directed beneath, but not meet- 
ing behind. The thorax is almost always furnished with ocular lobes. 
The tibias terminate in a dagger-like spine. These are large species 
averaging about half an inch in length ; oblong, cylindrical and pubes- 
cent. The larvae of some are found in the stems of thistles. Six N. A. 
species have been described, all belonging to the genus Clconus of 
Megerle. 
Sub-family LEPTOPSTDES. 
The most striking character of this group is the form of the eyes, 
which are large and placed transversly or crosswise of the head, and 
more or less narrowed and pointed at their lower extremity, whence, 
in common with some others, they have been denominated by Lacordaire 
Oxyopthalmes-, meaning pointed eyes. We have two N. A. genera, Pen- 
scopus, Sch., and Ophryastes, Sch. ; the former contains but one species, 
the P. erinaceus, Say, a sordid brown curculio, a little more than quar-
