BRUCHUS. 449 
transverse. Head short, eyes moderately separated. Thorax elongate, very narrow in 
front, the sides slightly concavely oblique, the surface densely covered with pubescence 
concealing the coarse punctuation, the pubescence chiefly flavo-griseous, but with nearly 
black marks on the front and middle, and an elongate triangular white mark at the 
base. Scutellum clothed with white pubescence. LElytra finely but deeply striated, 
variegate with the same colours as the thorax arranged transversely but irregularly, 
and the white markings consisting only of a few small isolated spots. Pygidium clothed 
densely with flavo-griseous pubescence, but with an elongate very conspicuous white 
mark at the base in the middle, and on either side of its apex a black spot. Under 
surface variegate with black, white, and yellowish-grey. 
B. mundulus differs in several important particulars from B. pictifemur, the species to 
which it is most similar in facies—the apical ventral plate being very short, and in the 
middle very reduced by the incurvation of the apex of the pygidium, the armature of the 
femora consisting of a small tooth and two scarcely perceptible denticles near it, and 
the apical spur of the tibie being very short, though slender and definite. Only one 
example is known to me. 
19. Bruchus cordifer. 
Testaceo-ferrugineus, tenuiter griseo-vestitus ; elytris ad apicem macula magna communi nigro-fusca; antennis 
pedibusque testaceis ; femoribus posterioribus latis, dente gracili denticulisque minutis duobus instructis. 
Long. 23 millim. (capite inflexo). 
Hab. Guatemata, San Joaquin in Vera Paz (Champion). 
Antenne not stout, subserrate internally, the penultimate joints only slightly broader 
than long. Eyes moderately distant. Thorax narrow in front, conical, clothed with a 
pallid pubescence, not variegate. Elytra very finely striate, clothed with pubescence 
like the thorax, but at the extremity with a common, conspicuous large cordate mark. 
Pygidium clothed rather densely with nearly white pubescence. Spur of hind tibia 
quite short. 
Only a single example of this minute species was obtained. The penultimate ventral 
rings being very short and the hind legs incrassate would place it in Schénherr’s Pachy- 
meri, it being in the structure of the antennee intermediate between his Stirps I and II. 
20. Bruchus celatus. 
Brevis, convexus, rufus; capite corporeque subtus in medio nigris; antennis pedibusque testaceis ; prothorace 
transversim conico, pallide flavo subvariegato; elytris post basin fascia lata pubescentie sparse pallida ; 
femoribus posterioribus haud incrassatis, denticulo parvo acuto instructis. 
Long. 23 millim. 
Hab. Panama, Bugaba (Champion). 
_ Antennee short and broad, not serrate; third joint scarcely longer than the second, 
6-10 each broader than long. Head small, eyes widely separated, vertex not carinate.
