BRUCHUS. 483 
98. Bruchus filarius. 
Angustulus, subdepressus, niger, griseo vestitus ; antennarum basi pedibusque anterioribus rufis, illis latioribus ; 
femoribus posterioribus dente minutissimo armatis. 
Long. 13 millim. 
Hab. Guatemata, Zapote (Champion). 
Antenne very broad, thickened from the third joint outwards, the basal two joints 
red, the others black, the penultimate joints strongly transverse. Thorax slender, but 
not so long as broad, the sides rounded and narrowed in front, the sculpture concealed 
by the rather dense clothing. Elytra rather elongate, finely striate. Pygidium with 
the pubescence along the middle denser. The terminal four ventral rings elongate. 
Front legs red, the apices of the femora and the tibie of the middle legs also of this 
colour. Hind femora with a very minute denticle ; tibia slender, without mucro. 
Only one example has been obtained. The structure of the antenne distinguishes it 
well from the allies, and it is also of unusually narrow form. 
99. Bruchus restrictus. 
Minimus, sat elongatus, niger, griseo vestitus; arftennarum basi pedibusque anterioribus rufis ; antennis parum 
latis, intus subserratis ; prothorace minus transverso ; femoribus posterioribus dente gracili denticulisque 
duobus minutissimis armatis. 
Long. 1% millim. 
Hab. Guatemata, Zapote, San Gerénimo (Champion). 
Antenne with the four basal joints yellow, the others black, the penultimate joints 
scarcely transverse. Thorax slender, not much narrowed in front, though a little 
rounded near the front angles, the punctuation concealed by the clothing. Elytra rather 
elongate, finely striate. Front legs entirely red; middle legs reddish with the femora in 
great part darker; hind legs entirely black, the tibia with a short mucro at the apex. 
Another minute and obscure insect, without any salient character. The thorax, 
though rather elongate, has but little of the conical form. Only one example is 
extant from each locality. 
100. Bruchus optatus. 
Minimus, haud elongatus, niger, griseo vestitus; antennarum basi pedibusque anterioribus testaceis ; antennis 
sat elongatis, serratis; prothorace transverso-conico, fortiter punctato; femoribus posterioribus dente 
gracili denticulisque duobus minutissimis armatis. 
Long. 14 millim. 
Hab. GuatemMata, near the city (Champion). 
Antenne moderately long; the three basal joints obscure yellow, the fourth joint 
small, serrate from the fifth joint outwards, the penultimate joints somewhat strongly 
transverse. Thorax much narrowed to the front, where the sides are but little rounded. | 
Pygidium rather small, perpendicular. Last four ventral rings rather short, subequal
