BRUCHIDAE. 
SPERMOPHAGUS PLUTO, sp. nov. 
Plate 13, fig. 3-4. 
Form stout. Head small. Antennae short, not serrate, the joints 
of the middle portion, at least, squarish. Prothorax showing moder- 
ately coarse and deep, closely placed punctures on the flanks, sculpture 
of the remainder of the underside not defined. Legs of moderate 
length for the family, the hind femora slightly thickened, hind tibia 
carinate, straight, with two unequal but fairly long spurs at the apex. 
Hind coxae not much dilated and scarcely narrowing the basal abdomi- 
nal segment. Length, 4.75 mm.; to elytral tips, 4 mm. 
Described from one specimen showing the underside. 
Type.— No. 2,646 M. C. Z. Florissant, Col. (No. 8,848 S. H.

The rounded tips of the elytra show through and at first sight give 
the impression of being enlarged coxal plates. While the aspect of 
this insect is decidedly bruchid, I have not been able to assign it to 
Bruchus because of the distinct spurs on the posterior tibia and have | 
therefore given it the above generic position rather than erect a new | 
genus upon the basis of the difference in form of body and in deyvelop- 
ment of the legs. The short antennae will separate it at once from 
S. vivificatus and the form of the hind legs will distinguish it from any 
of the Florissant species of Bruchus with which it might otherwise be 
confused. 
BRUCHUS PRIMOTICUS, sp. nov. 
Plate 18, fig. 6; Plate 14, fig. 1-2. 
Form robust. Head rather large, closely and minutely punctulate, — 
Antennae moderately stout, distinctly but not very strongly serrate. 
Prothorax minutely punctulate in similar fashion to the head but more | 
strongly and having in addition a moderately coarse and very close 
punctuation of medium depth, more pronounced at sides and base. | 
Elytra distinctly but rather finely striate, the striae with rows of — 
moderately small, approximate, elongate punctures, interstitial spaces 
minutely transversely rugose. Hind tibia curved and carinate or — 
grooved, the femur enlarged, with a rather small tooth and a row of |
