There is no description of this insect in the ‘ Etudes,’ but merely a comparison with 
a new species from Burmah, and in the Bull. Mosc. it is briefly characterized in tabular 
form ; it is probably near to B. pusillimus, but the scanty characters mentioned do not 
accord altogether therewith. 
SPERMOPHAGUS. 
Spermophagus, Schonherr, Cure. i. p. 102. 
Zabrotes, Horn, Tr. Am. Ent. Soc. xii. 1885, p. 156. 
This is a widely distributed genus, its largest and finest forms being found in the 
New World. The species are readily distinguished by their possessing two articulated 
spurs on the hind tibia. Dr. Horn (Joc. sup. cit.) has recently separated some of the 
North American species under the name of Zabrotes, but this step appears premature. 
The type of Spermophagus is S. titivilitius, Boh. Dr. Horn, however, differentiates 
his Zabrotes not from this form, but from S. robinie, Fabr., but I think it possible from 
itivilitius that it may prove to be structurally more similar to 
Dr. Horn’s Zabrotes than to Spermophagus robinie. The minor structural characters 
in the Bruchide are remarkably variable, and the separation of the front coxee is one of 
the most variable characters in the family. Another character relied on by the talented 
American Coleopterist to differentiate the genus from Spermophagus, I am not able to 
confirm ; he speaks of the claws as absolutely simple, but in the species of our fauna 
which I refer with very little doubt to Zabrotes, I find that though the claws are minute, 
yet they are lobed at the base, much as in other Bruchide. At present, therefore, the 
genus can only be accepted as a section of Spermophagus containing the European S. 
cardui, and other Eastern forms in addition to the New World species for which it was 
instituted. 
§ 1. Front core quite contiguous at the tip. (Zabrotes.) 
1. Spermophagus pectoralis. 
Breviter ovalis, parum convexus; pygidio corporeque subtus griseo-pubescentibus; prothorace elytrisque plus 
minusve vage griseo guttatis ; antennis elongatis, gracilibus, subserratis, articulis primo et secundo rufis ; 
pectore medio concavo denseque griseo-pubescente. 
Long. 2-27 millim. 
Hab. Mexico, Campéche (Sallé); Guatemata (Sallé), near the city, Duefias, Zapote,

Of very short form, broadest behind. Antenne long and slender, as long as the thorax 
and elytra together ; second joint more than half as long as the third ; joints 5-10 each 
slender, but with acute inner apical angle. Head and eyes small, the latter minutely 
facetted. Thorax very short, the sides narrowed and rounded in front, the base oblique
