than the females, of which sex four examples are before me. Sallé obtained the 
species from Sturm’s collection, the male being ticketed by this latter entomologist 
“ Bruchus plumicornis, mihi,” and the female “ Bruchus albiventris, mihi.” 
104. Bruchus callirhipis. 
Niger, supra variegatus ; elytris albido-nebulosis, pygidio corporeque inferius albido vestitis, antennis pedibusque 
anterioribus et intermediis testaceis, illis versus apicem fuscescentibus, pedibus posterioribus rufis, femo- 
ribus fuscescentibus; elytris fortiter regulariter seriatim punctatis. 
Long. 37 millim. 
Hab. Nicaragua (Sallé). 
I have seen only two female examples of this species, and, though no doubt very 
close to B. leucurus, yet, as the hind body is somewhat differently formed, I have little 
doubt they belong to a distinct species. The pygidium does not project so far down- 
wards, and is accurately adapted to the last ventral ring at the apex, and the ventral 
rings are a little convex in the longitudinal direction. The insect is also of rather 
shorter form, and the vestiture of the under-surface paler. The species was labelled 
“ B. callirhipis, Chevr.,” in Sallé’s collection, and I have preserved the name for it. 
105. Bruchus contaminatus. 
Niger, tenuiter griseo vestitus, vix variegatus; pygidio corporeque inferius grisescentibus ; elytris regulariter 
crenato-striatis ; antennis serratis, 
Long. 3-3$ millim. 
Hab. Mexico (Truqut), Guanajuato (Sallé), Jalapa, Oaxaca (Hodge). 
This species is of more oblong form than the allies; the surface is less orna- 
mented, and the clothing of the thorax and elytra allows the minute rugose sculpture 
of the surface to be perceived. The antenne are black, serrate from the fourth joint 
outwards, the third joint much longer than the second; the processes given off by the 
penultimate joints are short, only about as long as the basal joint. Eyes convex, not 
very widely separated. Thorax very short, greatly narrowed in front, the sides slightly 
convexly-arcuate ; the surface not uneven, densely minutely rugulose, with a slight 
depression in front of the scutellum griseo-pubescent. Elytra rather elongate, very 
regularly striate, the punctures of the strize elongate and so close to one another that 
the separations between each are indistinct; the interstices densely, minutely, rugosely 
fusco-pubescent, very minutely flecked with white. 
Twenty examples have been obtained of this species, but I am not able to find any 
sexual distinctions among them.
