BRUCHUS. 463 
51. Bruchus clandestinus. 
Pachymerus (?) clandestinus, Motsch. Bull. Mosc. 1878, 2, p. 246°. 
Hab. Panama, Aspinwall}. 
We have not received anything agreeing with this description, and the position of 
the species is quite doubtful ; but I place it here, as the antenne are said to be “ valde 
serratis.” It is recorded as found on the 2nd of March in the seeds of an ashy-yellow 
leguminous plant growing on the sea-shore. 
§ 4. Form short and broad, with large, broad, subperpendicular pygudium ; front coxe 
frequently minutely separated at the tip by a minute prosternal lamina; antenne 
short, only subserrate ; hind femora but little incrassate, usually armed with a 
single tooth, rarely unarmed, or with one or two additional dentecles. 
The character of the separated anterior coxe is of importance, as it is an approxima- 
tion to what exists in the neighbouring genera Spermophagus and Caryoborus ; it is 
unfortunately only very minute, and grades away so as to be quite absent in several species, 
52. Bruchus obscuriceps. 
Convexus, fusco-rufus, fusco griseoque vestitus ; capite brevi, lato, oculis distantibus ; prothorace transversim 
conico; pygidio elongato, obliquiter perpendiculari; antennis pedibusque anterioribus testaceis (illis 
interdum extrorsum nigris); femoribus posterioribus dente gracili denticulisque duobus armatis ; coxis 
anterioribus a processu gracili bene separatis. 
Long. 43 millim. 
Hab. Mexico, Vera Cruz (Sallé). 
Antenne short, the four basal joints slender, the others broad, the seventh to the tenth 
transverse ; third joint a good deal longer than the second. Head broad, extremely short, 
the vertex obscurely elevate along the middle ; eyes but little prominent, finely facetted. 
Thorax transverse, but narrow in front, and becoming gradually much broader behind; 
closely covered with a pallid grey pile that much conceals the sculpture, which consists 
of a minute, very dense, punctuation and more scattered larger punctures, Elytra rather 
finely striate, with patches of pallid fuscous and grey pubescence, scarcely causing a 
maculation. Pygidium very long, densely clothed with, pallid grey pubescence, as also 
are the under surface and the hind femora; these latter are a good deal dilated, and bear 
a rather long tooth and two other smaller, but very distinct teeth near it; the tibiz are | 
stout, very little curved, with a quite short apical spur. Last ventral segment elongate 
in the middle. 
Four examples. 
53. Bruchus brevicornis. 
Sat convexus, fusco-ferruginieus, fusco griseoque minus dense vestitus vix variegatus ; prothorace conico, crebre 
fortiter punctato; pygidio elongato, oblique perpendiculari ; antennis pedibusque anterioribus testaceis
