which are fine, more or less maculate at the outer margins, this lateral maculation 
behind the middle extending inwards so as to form a rudimentary band of spots. 
Breast very densely, ventral segments less densely, clothed with pallid pile. 
5. Bruchus ruficornis. 
Pachymerus ruficornis, Chevr. Aun. Soc. Fr. Bull. 1877, p. xe’. 
Hab. Mexico (Ott). 
A diagnosis /. c. is given without any comparative remarks, and no reference is made to 
the structure of the antenne, or breast, or the armature of the femora; but asI am still 
not able to find any species agreeing with the other characters given I must conclude 
this is a species we have not received. 
6. Bruchus cristicollis, 
Convexus, elytris quadratis, supra variegatis; prothorace valde inwquali, medio inequaliter longitudinaliter 
elevato, elevatione sulcata; pygidio densius longiusque pallide ochraceo-vestito, apicem versus trinoduloso ; 
femoribus posterioribus subtus ultra medium dente longiore armato, et ad apicem dentibus plurimis 
irregularibus. 
Long. 4 millim. (capite deflexo). 
Hab. Mexico, Yolos (Sailé). 
This is of about the size and form of B. longicollis, but is not closely allied to that 
species nor to any other known to me. Only a single example has been received, and 
from this I judge that the species will be readily recognized by the very uneven surface of 
the thorax, and from the fact that the pubescence of the upper surface is not so short as 
usual, and thus the maculations on the elytra are many of them slightly raised patches. 
The head is evidently rostrate, but rather broad ; the eyes moderately prominent, widely 
separated in front. The thorax is very narrow in front, the sides arcuately concave, 
the hind angles very acute, the surface with two irregular ridges along the middle; these 
ridges rise behind so as to form a considerable prominence a little distance in front of 
the scutellum, and between their highest point and the scutellum are clothed with more 
pallid pubescence, like that on the scutellum; on either side in front of the base there 
isa small but rather elevated prominence. The elytra are of a dark vinous-fuscous colour, 
and bear geminate series of quite distinct punctures, and are spotted with slightly raised 
patches of griseous and nearly black pubescence. The anterior legs are red; the posterior 
legs and the greater part of the under surface, black. the sculpture not so fine as usual ; the 
hind tarsi red. The metasternum is nearly flat, obliquely declivous in the middle in 
front. The armature of the hind femur differs from what obtains in B. longicollis, 
inasmuch as the smaller teeth are quite separated from the anterior one; they are 
irregular in size and four or five in number, rather crowded together, the outer of 
them minute.
