470 BRUCHIDES. 
66. Bruchus flaviventris. 
Brevis, niger, supra ochraceo, subtus pallido-griseo, vestitus ; antennis, pedibus abdomineque flavis; elytris 
disco rufo bimaculato; femoribus posterioribus muticis. 
Long. 24 millim. 
Hab. Guatema.a, Duefias (Champion). 
Antenne pale yellow, short, and very broad; third joint rather smaller than the 
second; joints six to ten strongly transverse. Eyes rather small, widely separated. 
Thorax transverse-conic, the sides scarcely rounded in front; surface very dull, densely 
sculptured, with larger punctures in addition to the dense sculpture, the pubescence 
very pallid ochraceous, uniform and rather abundant. Llytra moderately deeply 
striate, clothed with pubescence like the thorax, each with a large pale red spot near 
the suture. Pygidium yellow. Legs including the front coxe and the hind tarsi 
yellow. Hind femora not dilated, but rather short and broad, unarmed; tibie quite 
destitute of mucro. 
Of this very distinct species, only one example has been procured; though it bears a 
superficial resemblance to B. cruentatus, it is not closely allied to it or to any other 
recorded here. 
67. Bruchus medialis. 
Brevis, convexus, niger, supra ochraceo, subtus pallido-griseo, vestitus; antennis pedibusque testaceis, illis 
articulis sexto ad decimum fuscis; elytrorum medio late rufo-fasciato; femoribus posterioribus dente parvo 
armatis. 
Long. 2 millim. 
Hab. Mexico, Guanajuato (Sallé). 
Antenne short and broad, third and fourth joints small, each smaller than the second 
joint. Eyes rather small and widely separated. Thorax short, greatly narrowed in front, 
the sides rounded in front, the surface densely and rather finely punctulate, and with 
a rather dense yellow pubescence. Elytra short, rather deeply striate, the interstices 
aciculate not punctulate; each withavery large pale-red mark nearer the base than the 
apex, starting from the outer margin and reaching the suture, except for the sutural 
interval which remains black. Pygidium rather abundantly clothed with pallid 
pubescence, rather large and convex. Legs bright red, front coxa and the base of the 
hind femora black. Hind femora not dilated, and armed only with a small sharp 
tooth ; tibia with the anterior angle scarcely longer than the other digits. 
Of the three examples on which I describe this species two are males, and have the 
terminal ventral ring shorter in the middle. 
68. Bruchus interruptus. 
Brevis, minus convexus, subrotundatus, niger, breviter albido pubescens; antennis pedibusque testaceis, illis 
extrorsum fuscescentibus; elytris rufo-signatis, striatis, striis fortiter punctatis; femoribus posterioribus 
dente sat elongato armatis, 
Long. 23 millim.
