IXSECTS AFFECTING STOEED PRODUCTS. 
While there is no great difference in the size of the two species, 
pisorum averages a little larger. The following technical description 
of rujimana is adapted from Horn: 
Oblong oval, black, subopaque. Head black, densely punctulate, sparsely clothed 
with ochreous pubescence. Antennse black, four basal joints rufous. Thorax wider 
than long, sides moderately rounded in front of tooth, sinuate behind it, tooth at mid- 
dle obtuse, moderately prominent; surface opaque, densely punctate, and with a 
small whitish triangular space in front of scutellum. Scutellum subquadrate, emar- 
ginate at apex, sparsely clothed with cinereous hairs. Elytra longer than wide, feebly 
convex, sides moderately rounded, surface more shining than the thorax, moderately 
striate, intervals flat, densely punctulate, and with the basal margin, base of suture, 
and two irregular transverse bands of whitish hairs. Pygidium clothed with cinereous 
hairs and with two nearly obsolete oblong black spots. Body beneath black, densely 
punctulate, and clothed with cinereous hairs. Anterior legs rufous, except their tarsi, 
apex of tibiae, and base of femora, which are piceous. Middle and posterior legs 
black. 
Length: 0.14-0.18 inch (3.5-4.5 mm.); width: 0.8 inch (2.4 mm.). 
The synonymy of this species is as follows :

The Bruchus granarius L. is Laria atomoria L.; Syst. Nat., 12th ed., p. 605, 1766-1768. 
The beetle is shown in figure 11, and figure 12, representing the 
pea weevil, is introduced for comparison.

From Mr. I. J. Condit, San Luis Obispo, Cal., under date of April 
18, 1911, were received the eggs of this species found on young pods of 
the broad or horse bean (Viciafaba). The pods were just beginning 
to form in many cases, some being as long as 2 inches. In some 
cases as many as nine eggs were found on one small pod and one 
was observed on the withered calyx lobe of the flower. Few beetles 
were observed and none was detected in the direct act of oviposition. 
Evidently this is accomplished mainly at night.
