anteriorly, and separates the coxae by about two-thirds of their own 

 width. Claws small, entirely free. Length 2.2-3.1 mm.; width 

 0.9-1.3 mm. 



Florida (Tampa, Baldwin and Enterprise). The disposition of 

 the scanty vestiture is somewhat remarkable ; for example, on the 

 fifth interval each puncture bears a minute and simple seta, but 

 every third or fourth puncture l)ears instead, a very large fan-shaped 

 scale placed in a transverse position. In spite of the great differ- 

 ence in size the present species and signatipes are closely allied. 



In the species of this group the scattered scales seem to be easily 

 removable, while in semula they are exceedingly persistent. 



4 Plesio1>aris aemilla. n. sp. — Snbcylindrical, strongly convex, shin- 

 ing, deep black througliout, the vestiture consisting of short broad white scales 

 which are large in the dense spots, but elsewhere small ; the scales are only 

 present on the pronotum in an anteriorly dilated lateral vitta, which is pro- 

 longed inwardly along the basal margin almost to the middle, then abruptly 

 flexed anteriorly and outwardly as a narrow line terminating at lateral third 

 and middle of the length ; on the elytra the scales are condensed in four small 

 almost equidistant spots on the third interval, of which the basal is the largest, 

 and thence to the side margins are widely but almost evenly scattered, but 

 sometimes forming three spots on the fifth interval ; on the under surface they 

 are very dense on the meso- and metasternal side-pieces, and at the sides of 

 the last three ventral segments. Head and beak not very strongly punctured, 

 the latter short, very thick, .strongly arcuate and subequal in length to the 

 prothorax, the antennae inserted a little beyond the middle, the basal joint of 

 the funicle short, not twice as long as wide, the second and third very short, 

 subequal, the club about as long as the preceding six, with its basal joint 

 composing one-third of the mass. Prothorax one-third wider than long, the 

 sides parallel and straight in basal three-fourths, then broadly subangulate, 

 thence convergent, nearly straight and not at all constricted to the apex, 

 the latter truncate and two-thirds as wide as the base, the latter transverse 

 almost straight, the median lobe subobsolete ; disk without median line, the 

 punctures deep, moderate in size, very dense but not crowded. Scutellum 

 very small, rounded. Elijtra more than twice as long as the prothorax and 

 a very little wider, parallel, parabolic in apical third, very finely but deeply 

 striate, the intervals flat, moderately wide the third and fifth much broader 

 than the others, each with a series of small feeble rather distant punctures ; 

 humeral tuberosities very feeble. Prosternum flat, separating the coxfe by 

 rather more than their owu width. Length 1.6-1.7 mm. ; width 0.65-0.7 mm.

This species was confounded by Dr. LeConte with the Zimmer- 

 mann specimen from South Carolina, identified by him as T-signum 

 Boh., and referred to below under disjuncta. It is a much smaller
