458 BRUCHIDES. 
Pygidium rather densely clothed with ochraceous pubescence. Under surface nearly 
black, very little variegate. Hind femora a good deal incrassate ; tibiz but little curved, 
armed at the apex with a very short mucro. 
40. Bruchus puellus. 
Subtus niger, griseo-vestitus ; supra fuscus, griseo-variegatus ; antennarum basi pedibusque testaceis ; femoribus 
posterioribus dente gracili denticulisque duobus armatis, tibiis mucrone elongato. 
Long. 23 millim. 
Hab. Panama, Volcan de Chiriqui below 4000 feet, Bugaba, Los Remedios 
(Champion). | 
Antenne rather short and slender, the four basal joints yellow, the others dark; 
second, third, and fourth joints subequal in length, penultimate joint slightly transverse. 
Elytra of a tawny colour differing little from that of the rest of the upper surface, but 
submaculate with patches of more pallid pubescence, and also with a few oblong patches 
of a darker tawny or fuscous colour. . 
This species cannot be treated as a small variety of B. obsoletus on account of the 
elongate mucro of the hind tibia. Its structural characters are almost the same as 
those of B. argutus, but the very different coloration leaves little doubt the two are 
distinct. Four examples are referred by me to this species; one of the two from the 
Volcan de Chiriqui is of broader form, with shorter, entirely testaceous, antenne.

This insect is said to be very abundant and destructive in the United States17, but 
not to be very variable. I have no evidence of its being abundant in our region, but it 
exhibits considerable variation therein. The synonym of B. pallidipes is given on the 
authority of Jekel*, and it is quite probable that some of the other descriptions in 
Schonherr’s work (B. tetricus and B. ventralis, e. g.) may prove to refer to the same 
species. I have adopted the name used by Horn, though B. obtectus, of the same date, 
is better known in Europe. In the Munich Catalogue B. obtectus is said to be the 
same as B. mimosw, Fabr. & Oliv., but this appears to me excessively doubtful.
