2 CatapastllS diffllSUS n. sp. — Rhomboid-oval, rather stout, convex, 

 black, the legs and antenna? throughout pale rufo-testaceous : vestiture as in 

 conspersus, the scattered white scales of the elytra larger and broader. Head 

 finely, very densely punctate, the impression obsolete ; beak and antennae 

 nearly similar to those of conspersus. Prothorax one-half wider than long, 

 conical, the sides feebly, evenly arcuate ; subapical constriction distinct ; apex 

 truncate, a little more than one-half as wide as the base, the latter transverse, 

 the median lobe small but rather prominent ; disk coarsely, very densely 

 punctate, with traces of a fine impunctate line. Scutellum small, rounded, 

 very densely clothed with white scales. Elytra distinctly wider than, and 

 obviously more than twice as long as, the prothorax, parabolic, the humeral 

 callus rather prominent laterally ; disk not coarsely, deeply, abruptly striate, 

 the intervals flat, twice as wide as the grooves, finely, closely, confusedly 

 and subtransversely punctato-rugose. Abdomen nearly flat, closely punctured 

 and moderately densely squamulose, the middle of the third and fourth seg- 

 ments glabrous except along the apex ; fifth segment rather longer than the 

 two preceding. Length 2.2 mm. ; width 1.15 mm. 



Florida (southern). 



This species is closely allied to conspersus, and resembles it in 

 structure and vestiture, but differs in its slightly more robust form, 

 pale legs and antennae, more transverse and more coarsely punctured 

 prothorax, and in several other characters. It is described appa- 

 rently from the female, but there is very little sexual disparity in 

 this genus. 



BARINUS. 



Casey— Bull. Cal, Acad. Sci., II, 1886, p. 255. 



In this genus the beak is as short, thick and arcuate as in Baris, 

 although beyond this mere suggestion, there is nothing at all in 

 common. As in Barilepton, to which Barinus is closely allied, 

 the head is larger in proportion to the size of the prothorax than in 

 any of the other genera, and the tarsi have the second and third 

 joints dilated, very broadly so in biwttatus, but Barinus can always 

 be readily distinguished by the tarsal claws, which are two in 

 number and completely connate through at least one-half of their 

 length. 



The antennae are inserted just beyond the middle of the beak, 

 very near the median line of the flank, the scrobes rapidly oblique, 

 the scape nearly attaining the eye, the club moderate and the basal 

 joint of the funicle unusually long, although varying somewhat in 

 length in the different species. The mandibles are small, stout, 

 feebly arcuate externally, decussate and with a large internal notch.
