BRUCHUS. 459 
42, Bruchus mexicanus. 
Niger, pallide griseo-vestitus, supra rufo griseoque variegatus ; antennis brevibus pedibusque testaceis ; femoribus 
posterioribus dente parum elongato denticulisque tribus instructis. 
Long. 23 millim. 
Hab. Mexico, Guanajuato (Sallé). 
Antenne short and stout, entirely pale yellow, third joint only slightly longer than 
the second or the fourth. Head very short. Thorax densely clothed with a variegate 
pubescence of fuscous grey and pallid grey or white. Elytra reddish, marked with 
fuscous, especially at the sides, and much covered with pallid pubescence. Legs pale 
red, coxe black. Hind femur with a slender, not very long, tooth, and with three con- 
spicuous denticles close to the tooth, forming, in fact, a prolongation of its hind 
margin, the tooth not much more prominent than the first of the denticles; the tibia 
is short, but little curvate, furnished at the apex with only a slight prolongation of its 
anterior angle, not long enough to be called a mucro. In the female the last ventral 
ring is twice as long as that preceding it, while in the male it is only of the same 
length. 
Seven examples.

We have not received anything agreeing with this description ; the species may pos- 
sibly be an ally of B. placidus. In Sallé’s collection B. saliei was identified as this 
species, but, I think, erroneously. 
§ 3. Thorax conic, its sides not: concavely arcuate; antenne rather elongate, serrate 
internally ; hind femora moderately incrassate, armed with a tooth and two or 
more denticles. 
The character connecting the species of this group is the rather long, serrate 
antenne. ‘The facies is that of our European B. canus. Species 44 to 48 are dark in 
colour, species 49 and 50 pallid. 
44. Bruchus ptinoides. 
Niger, opacus ; pedum apicibus flavis, corpore subtus tenuiter albido-vestito, supra tenuissime albido-fasciato ; 
antennis sat elongatis, intus subserratis; prothorace conico, inequali; elytris post basin transversim depressis ; 
femoribus posterioribus dente sat elongato denticulisque minutis quinque instructis. 
Long. 23 millim. (capite deflexo). 
Hab. Guatemata, Aceituno, San Gerdnimo (Champion).
