sinuate near each basal angle, the two lateral sinuations being separated by 

 a very broad and feeble tooth ; disk strongly convex, not elevated along the 

 middle, strongly ruguloso-punctulate, having at the base a short and strong 

 medial canalicnlatiou, also feebly impressed at the base on each side of the 

 middle. Scutellum wider than long, transversely sub-oval, not densely 

 pubescent. Elytra at base very slightly wider than the pronotum ; sides 

 parallel and very feebly arcuate ; each elytron broadly rounded behind ; 

 disk distinctly longer than wide, not impressed along tlie suture, moderately 

 convex ; striae strong and impressed, scarcely punctate ; intervals nearly 

 tlat, strongly ruguloso-reticulate, shining ; humeri very prominent. Pygi- 

 diiim very large, much longer than wide, triangular, sides all broadly arcuate, 

 disk strongly and coarsely ruguloso-punctulate, black, rufous along the base, 

 sparsely pubescent, more densely so at the base near the elytra, apex 

 narrowly rounded. Ventral segments abruptly and broadly rufous at tlie 

 sides near the elytra, the rufous color extending on the last segment tb rough- 

 out its extent, remainder black. Femora not dentate ; posterior tibiae having 

 two large strong and unequal terminal teeth and also several very minute 

 ones ; first joint of the posterior tarsi cylindrical distinctly arcuate more 

 than three-fourths longer tlian tlie remainder, second much longer than the 

 tliiid. Length 1.5 mm.

Much smaller than inipiger Horn, after wliicii it should be placed 

 in the catalogue; the shape of the pronotum is very different in the 

 two species. 



In tliis connection it should be stated that there are two species of 

 Bruchus which may be easily confounded, viz., hibisci Oliv. and 

 alboscittellatus Horn. I have identified a series in my cabinet as the 

 last-iuimed species, although they were taken in Pennsylvania and 

 Delaware and vary in size from 1.7 to 2.2 mm. Dr. Horn gives the 

 locality as Georgia, Louisiana and Missouri, and, as he states the 

 length to be 2.;} mm., the species is seen to have a great range of 

 variation in length as well as an extended distribution. Tlie 

 scutellum is smaller than that of hibisci and the form of body more 

 slender; the posterior femora has a large tooth and between it and 

 the tip two minute dentacles almost e(piidistant from each other and 

 the large tooth, and also near the latter and toward the base of the 

 femur a second smaller and much shorter tooth.

 liead and pronotum black, elytra dark rufous, under surface dark pioeous- 

 brown, legs and antennae not paler ; pubescence of upper surface very short 

 and ratber dense, briglit fulvous, less conspicuous on the elytra; integu-
