indefinite fuscous spots to be perceived. Hind tibia with acute and slightly prolonged 
inferior angle, not long enough to be termed a spur. 
This species is no doubt allied to B. obscuriceps, though it has a shorter thorax; the 
front coxz are actually contiguous at the tip, nevertheless there is a very slender lamina 
concealed by their apices, and this projects beyond the coxz as an excessively minute 
process, 
Only two examples of uncertain sex were found by M. Blancaneaux ; the ground-colour 
in one is more rufescent than it is in the other. The Mexican example is a pinned 
individual in bad preservation, but appears to be really the same species. It was 
labelled in Sallé’s collection “B. minutus, Fabr.,” but it is clear that this species is 
not the B. minutus of either Fabricius or Schénherr; further on (no. 107) I have 
recorded another species that is apparently less unlikely to prove to be the Fabrician 
insect. 
56. Bruchus guttifer. 
Brevis, convexus, subtus dense pallido-griseo vestitus, supra tenuiter vestitus, rufescens; in elytris guttulis 
minimis pallidis transversim positis ; prothorace transversim conico ; femoribus posterioribus dente parvo 
armatis. 
Long. 3 millim. 
Hab. Muxico, Jalapa (Hoge), Vera Cruz (Sallé); Guatemata, Duefas, Capetillo 
(Champion). 
Antenne short, the basal joints yellow, the external ones infuscate; the sixth to the 
tenth joints strongly transverse. Thorax rather strongly transverse, but regularly 
conical, the sides being gradually narrowed from the base to the front, and not at all 
rounded in front, dark red, coarsely punctate, and only very sparingly clothed. LElytra 
very finely striated, dull red, with six very minute white dots arranged in an irregular 
transverse series across the middle. Under-surface and pygidium densely clothed 
with pallid griseous pubescence. 
The structural characters are similar to those of B. inanis, except that the angle of 
the hind tibia possesses a short, slender spur. | 
I have seen four Mexican exponents of this species, and two from Guatemala; the 
one found at Capetillo is a variety in which the thorax and elytra are fuscous instead 
of rufescent.
