tate and pubescent ; last segment not impressed, having longer and more con- 

 spicuous pubescence. Length 1.5 mm. 



Texas. Cab. LeConte, Belfrage and Schwarz. 



The dual nature of the pubescence has been referred to as a 

 group character, and has not been mentioned in the description. 

 The longitudinal groove in the elytral epipleurse near the apex is 

 very fine, and less developed than in group I. 



I., seriatus n. sp. — Oval, convex, about three-fourths longer than wide, 

 rather gradually pointed behind, castaneous above, rufo-ferruginous beneath, 

 feebly shining. Head convex, extremely minutely and rather densely punc- 

 tate. Prothorax a little more than twice as wide as long ; sides nearly straight ; 

 apex fully three-fourths as wide as the base ; basal lobe small, rather feeble ; 

 disk excessively minutely, feebly, rather densely punctate, the median groove 

 completely obsolete. Scutellum very small, slightly longer than wide, acutely 

 pointed; sides straight ; surface minutely, feebly reticulate. ^/_(/^ro four times 

 as long as the prothorax and nearly two-fifths wider ; sides feebly arcuate 

 anteriorly and not coarctate with those of the prothorax, the width at the 

 humeri being distinctly greater than the base of the latter ; surface polished, 

 not reticulate, very minutely punctate, the punctures about as large as those 

 of ocatus, and separated by from four to five times their own diameters, some- 

 what unevenly distributed. Prosternum rather dull but not punctate, the 

 median groove fine but deep and distinct ; metasternum strongly and sparsely 

 punctate, the punctures decidedly larger than those of the elytra, and sepa- 

 rated by about three times their own widths. Abdojnen finely, sparsely punc- 

 tate, the punctures perforate, scarcely as large as those of the metasternum, 

 but rather larger than those of the elytra, separated by from four to five times 

 their own widths ; fifth segment entirely impunctate, except a single line of 

 punctures along the base. Intermediate tarsi nearly two-thirds as long as the 

 tibiae, the joints two to four very short, transverse and oblique, almost exactly 

 equal. Length 1.2 mm. 



Florida. Mr. Schwarz. 



The large hairs of the elytra are but slightly longer than the fine 

 short subappressed ones, and are entirely inconspicuous; there are, 

 however, on each elytron four series of long erect white setae which 

 are very widely spaced ; these contrast strongly with the general 

 vestiture, when viewed under light coming horizontally along the 

 axis of the body and from the front. I have not noticed these setae 

 in any other species, although they probably exist, and are simply 

 more prominent in the present case because of the extraordinary 

 shortness of the general pubescence. This last character will easily 

 distinguish sei'iatus from ovatus. The elytral pubescence is fulvous 

 in color and entirely devoid of maculation.
