78 DR. HARRIS’S REPORT. April, 
one or two inches. In this they are allowed to stand an hour or two, 
when all the bugs will be found dead and floating, and the pease will 
be in a state for immediate planting. ‘The Baltimore Oriole or hang- 
bird, is appointed to check the increase of this insect, by picking 
from the green pea the larva on which it feeds. 
In the genus Anthribus, the head is elongated into a broad snout 
or rostrum. The body is short, thick, and obtuse, or truncated 
behind ; the antenne are straight, abruptly thickened at tip into a 
three-jointed mass or club; the thorax is transverse, broadest behind, 
and lobed ; the posterior extremity is covered by the elytra. 
Anthribus marmoreus lives in the larva state in the solid wood of 
the oak, where also it undergoes its metamorphoses. 
The succeeding insects, which are furnished with snouts or rostra, 
belong to the family Cureulionide, so named from a genus of Lin- 
nzus in which they were included. They are popularly named 
weevils, and are widely spread through vegetation; almost every grain 
and seed having its peculiar species, and the trunks and leaves of a 
great number of plants are also infested by them. The larve are 
more or less oval or approach to a conical form. They are desti- 
tute of legs, unless we may call by that name certain fleshy tuber- 
cles at the sides of the body, besmeared in some species with a 
tenacious slime, which assist them in their motions. These motions 
are effected by the alternate contraction and extension of the seg- 
ments of the body. They have a horny head, by which they are 
distinguished from the maggots of flies. The pupe do not differ 
greatly from those of other coleopterous insects, exhibiting the rudi- 
ments of feet and wings through the thin pellicle which envelopes 
every part. 
According to Kirby and Spence, several species of Harpalus 
(insects belonging to the Carabide) prey upon the perfect insects. 
The larve fall victims to several Ichneumon flies, to woodpeckers, 
and to other birds. 
The habits of the genus Brenthus have not hitherto been described. 
Their characters are these. Antenne straight, not tapering at the 
ends ; body hard, elongated, somewhat cylindrical ; head, rostrum or 
beak straight and porrected, in the female very slender and long, in 
the male short, robust, dilated at the end, and with large and dis-
