Four basal joints of the antenne sordid yellow; fourth small, the penultimate joints 
rather strongly transverse. Thorax much narrowed from the base to the front, and only 
slightly rounded near the front angles; very coarsely punctate, the punctuation visible 
notwithstanding the variegate pubescence ; this is of a grey colour, denser about the sides 
on the basal lobe, and a very narrow line along the middle. Elytra variegate with two 
shades of grey leaving black spots, the most conspicuous of which is a very large one 
on each side. Pygidium grey; under surface pallid grey, the pubescence condensed 
on the pleure, so that this part of the sides is white. Hind tibia armed with a long, 
slender mucro. 
This is very similar to B. pullatus in Group § 6, but the unique example is twice the 
size of any individual I have seen of that species, and has a more conical thorax. 
30. Bruchus ornatus. 
Supra pallide rufus, densius pallide griseo-vestitus, fusco-maculatus; subtus niger, abdominis apice rufo ; 
antennis brevibus pedibusque testaceis ; femoribus posterioribus nigro-plagiatis, dente gracili denticulisque 
duobus armatis. 
Long. 23 millim. 
Hab. Mexico, Guanajuato (Sallé). 
Antenne short and stout, pale yellow. Thorax densely clothed with pallid subvariegate 
pubescence which is thickest and more pallid in front of the scutellum. Elytra marked 
with numerous small dark spots, and with a pubescence of a griseous and ochraceous 
colour. The hind tibia is without mucro at the extremity, there being only a slight 
prolongation of the anterior angle. 
Although the legs differ little from those of B. argillaceus, yet the broader and shorter 
pallid antenne and the coloration are so different that I cannot place this as a variety 
of B. argillaceus. A single example is all that is known. In coloration it resembles 
B. debilicornis of Group §1. &% 
One example only.

I have not seen this species, but have little doubt that it will prove to be allied to 
B. argillaceus. An example from Arizona sent by the late Mr. Morrison as being
