flat, oblong, with tea fine striae on each ; there is a white clot on the 
2nd interstice on each side of the suture towards the base, and a wavy 
transverse line of broken white dots beyond the middle, surrounded by 
black spots and patches, especially towards the apex, which bears 2 pale 
dots: wings ample and folded: abdomen extending beyond the elytra, 
convex, and sloped off, forming a large semi-ovate apical joint, clothed 
with greyish pubescence, bearing 2 black or brown spots at the base 
more or less concealed, and 2 black shining ones near the apex: under 
side silky and slate-coloured, a whitish spot at the hinder angles of the 
pleurae, and a white lateral dot on each of the hve following abdominal 
segments: legs clothed with silky grey pubescence j hinder pair very 
long, with the thighs stout, having a minute tooth beneath near the 
apex ; the shanks bidentate at the apex : the other 4 legs are much 
shorter and slenderer, with the tibiae and tarsi tawny ; the feet are 
4-jointed, the hinder long and black, the basal joint greatly elongated, 
3rd joint bilobed, 4th clavate ; claws small, hooked at the base. Length 
from 2 lines to 2J (fig. 35 j f. 34, the female, highly magnified). 
The Bruchus which abounds in this country in our fields and 
gardens, if not originally a native species, is at any rate perfectly 
naturalized, and the importation of foreign peas and beans for 
seed is annually increasing the numbers. Some foreign long-pod 
beans which I purchased last spring were infested to a great 
extent. I picked out, as far as I was able, those which contained 
insects and planted the rest, yet I saw a few of the Bruchi 
running over the bean-flowers in the month of June. This 
species received from Linnaeus the name of 
7. Bruchus granarins, the Grain Bruchus. It is smaller than B. Pisi, 
being generally less than 2 lines in length (fig. 31) ; but is very similar 
in form. It is black and punctured, but less densely clothed with short 
brown hairs ; the antennae are not so much incrassated at the extremity, 
but the 4 basal joints are ferruginous : the thorax is not so broad, and 
more bell-shaped ; the lateral tooth is very indistinct ; and, besides the 
white hinder angles and the triangular spot before the scutel, there are 2 
white dots on the disc : the wing-cases are sprinkled with whitish spots 
of hairs, the suture forms a brown stripe, whitish at the base ; there 
are 4 white dots on the disc, separated by a black longitudinal line : the 
wings are ample : the exposed apical joint of the abdomen, called the 
pygidium, is densely clothed with greyish pubescence, in certain lights 
exhibiting 4 minute indistinct dark dots : the under side is similarly 
spotted : the legs differ in having the first pair only ferruginous, with 
the thighs of the same colour, excepting the base, and the hnider shanks 
have the internal spine elongated (fig. 32). Obs. Specimens of tliis 
insect are frequently so rubbed that they appear almost entirely black, 
from the hairs or pubescence being worn off. 
This species, which is everywhere abundant as early as Fe- 
bruary on the furze when it is in bloom, inhabiting also the 
flowers of various other plants in the beetle state, as the rhubarb.
