Arms. ITS LADY-BUG DESTROYERS. 1* IN E-MARK ED COCCINELLA. 
coarse brown veins bounding a nearly triangular cell placed on the middle of the outer mar¬ 
gin, from the inner angle of which a vein extends inward and backward which is gradually 
more slender and the last half of its length abortive and scarcely perceptible; a very coarse 
vein orossing the middle part of tho wing ohliqucly, forward of the triangular cell. 
Oat Allotria, Allolria Avence, new species. 
Black, polished; feet brownish; antennae longer than tho body, 15-jointed. Length 0.06. 
Head nearly globular when viewed from above, egg-shaped when viewed laterally, with 
the smaller end downward; small short bristles scattered sparsely on the face but dense on 
the throat. Antennae longer than the body, equalling tho tips of the wings, thinly bearded 
with short stiff inclined hairs and a row of longer ones surrounding the apex of each joint; 
basal joint no thicker than tho others, long egg-shaped with the smaller end downwards and 
tapering into a slightly curved podicol; second joint globular; third and following joints 
cylindrical, about thrice as long as thick, cut ofT transversely at their tips, and at their bases 
suddenly tapering into a short pedicel which is a third of the thickness of tho joints and less 
long than thick; last joints soarcoly diminished in thickness and not at all in length, the end 
joint long egg-shaped. Wings smoky-hyaline, with a row of short inclined bristles along 
the outer edge and fringed with longer ones at their ends and along tho inner margin of the 
hind pair; their veins the same as in A. Tritici , and various other details which it is unne¬ 
cessary to repeat. 
Nine-marked Coccinella, C. 9-notata, Ilerbst. (Coleoptcra, Coccinellidaa.) 
In addition to the internal parasites above spoken of, we have 
several other insects which are efficient destroyers of tho grain 
aphis, slaughtering it to feed upon it. One of these which will 
be most apt to attract notice, is a pretty beetle, a species of lady 
bug or lady bird, named the Nine-marked Coccinella ( C. d-notata, 
Ilerbst) and pertaining to the family Coccinellidce in the order 
Coleoptera. It is one of the most common species of lady bug in 
our State, and feeds upon several kinds of plant lice, but appears 
to prefer this on grain to any other. Hence It is met with in 
our grain fields in greater plenty, according to my observations, 
than in any other situation. It is readily recognized, being about 
the form and size of a half pea, of a bright red, sometimes a yel¬ 
low color, with nine small black spots on its wing covers. 
Its larva is more voracious than the perfect insect in feeding 
upon these plant lice. It is often noticed, walking actively about 
upon the straw at the time the grain is harvested, and has such 
a scorpion-like look that it is on this account sometimes destroyed 
by persons who are ignorant of its friendly character. It is 
three-eighths of an inch long when fully grown, and resembles a 
very flexible worm with three pairs of long stout legs on its 
breast. It is blue-black, and appearing as though coated over 
with a glaucous bluish grey bloom, and on each side, near tho 
middle, are two bright red or orange spots, occupying the outer
