BRUCHUS. 469 
Hab. Guatemata, near the city, Capetillo (Champion). 
Antenne only moderately long and broad; third and fourth joints slender, subequal, 
the penultimate joint about as long as broad. Head small; eyes scarcely at all prominent, 
widely separated. Thorax rather short, rounded at the sides so as to be much narrowed 
in front, black, very finely punctate, but with some larger, but still quite fine, punctures 
scattered over it, slightly shining, the surface receiving a somewhat leaden tint from 
the very minute pubescence; basal lobe foveolate in front of the scutellum. LElytra 
rather finely striate, each with a large red spot occupying the larger part of the surface, 
reaching the outer margin, but not the base, apex, or suture; interstices densely, minutely 
punctulate, the pubescence very minute. Pygidium broad, rather large, the pubescence 
very fine. Posterior femora not dilated, each with a rather slender acuminate tooth ; 
tibie straight, only moderately broad, without mucro. 
Only one example was met with in each locality; they represent the two sexes, the 
last ventral ring in the male being considerably excised. Although superficially similar 
to some of the maculate varieties of B. instabilis, this species is very distinct therefrom ; 
the front coxe are separated by a fine lamina, the hind femora not canaliculate. 
64. Bruchus trisignatus. 
Brevis, subrotundatus, minus convexus, niger, omnium brevissime pallido vestitus, elytro singulo macula magna 
humerali rufa; antennarum basi testacea; prothorace densissime punctulato; pygidio basi albido tri- 
maculato; femoribus posterioribus dente singulo armatis. 
Long. 3 millim. 
Hab. Panama, Bugaba (Champion). 
Head short and broad; eyes widely separated. Antenne short and broad, the penul- 
timate joints transverse. Thorax broad, rather short, greatly narrowed in front, the sides 
rounded; surface dull owing to a very dense minute punctuation, the basal lobe not 
impressed. Elytra each with a large humeral red spot occupying nearly half the 
surface, rather finely striate, the strie punctured, the interstices densely punctulate. 
Pygidium broad, punctate, with three very conspicuous large spots of white pubes- 
cence at the base. Hind femora scarcely incrassate, each armed with a rather small 
tooth; tibia short, very thick, straight, with a short, strong mucro at the extremity. 
Front coxe distinctly separated. 
Only one example was obtained of this very distinct species.
