BRUCHUS. 485 
Hab. Mexico, Cordova, Toxpam (Sallé), Cerro de Plumas (Hége); British Honpuras, 
Belize (Blancaneaux); Guatemata, El Tumbador 2500 feet (Champion). 
Thorax short, greatly narrowed in front, the sides concavely arcuate, the surface rather 
uneven, with a longitudinal depression along the middle, the sides of which are but 
little elevated, the depression in front of the scutellum broad and indefinite; the 
surface bears rather numerous coarse punctures, which are closest and most distinct 
near the sides and front margin. Elytra a little depressed along the suture, with 
numerous series of very large punctures, the interstices slightly uneven. Pygidium 
very elongate, densely covered with a griseous or ochreous pubescence, and with rather 
numerous deep punctures covered by the clothing. Under-surface dark, being only 
sparingly clothed, with a more or less conspicuous condensation of pallid pubescence on 
the posterior portion of the parapleure. 
In the male, joints 5-10 of the antenne are each furnished with a long process, each 
process being about as long as joints 6-10 together; the fourth joint also possesses a 
shorter, though still elongate, process, and the terminal joint is elongate. In the female 
the fourth joint is nearly simple, the fifth to the eighth becoming gradually broader, the 
fifth being at the apex rather broader than long ; joints 8-10 are similar to one another, 
and the terminal joint is short. In the female the last ventral ring is excessively short 
in the middle. A male example is figured. 
103. Bruchus leucurus. 
Niger, supra brunneo vestitus; elytris griseo submaculatis, pygidio corporeque inferius pallide ochraceo 
vestitis, antennis pedibusque anterioribus et intermediis testaceis, illis apicem versus fuscescentibus ; 
elytris fortiter regulariter, seriatim punctatis; antennis maris longius, femine breviter, flabellatis. 
Long. 3-33 millim. 
Hab. Mexico (Sallé, ex coll. Sturm), Cerro de Plumas, Paso del Macho (Loge) ; 
GuatemaLa, Capetillo, Calderas (Champion). 
This species is very closely allied to B. cubiciformis, but is clothed above with more 
pubescence, usually of a more pallid colour, and is readily distinguished by the dense 
pallid clothing of the ventral rings; the elytra are rather more elongate, even, and 
with more regular rather less coarse rows of punctures; the pygidium and last ventral 
ring are rufescent, the former more or less maculate with black; but this coloration 
is much concealed by the pallid clothing of these parts. The pygidium is considerably 
narrower than it isin B. cubiciformis. The structure of the antenne and the last 
ventral ring are apparently similar to those of the corresponding sex of B. cubiciformis ; 
but in the female the last ventral ring is shorter in the middle, differing in this respect 
but little from the other sex; the antennz of the female appear to be more clavate than 
those of the same sex of B. cubiciformis, owing to the fact that joints 4-6 are more 
slender. I have seen only two examples of the male, both of which are of darker colour
