4 Punctures toward the elytral base notably coarse and close-set; 

 impression of the fifth ventral of the female very feeble and not 

 closely approaching the base; body larger, stouter; head somewhat 

 swollen; antennae (9) with the third joint much longer than the 

 fourth; prothorax very densely cinereo-pubescent; elytral cinereous 

 band forming a dense zone from basal sixth to three-fifths, where it 

 is abruptly limited except near the suture. Length (cT 9 ) 14.0- 

 15.0 mm.; width 4.4-5.0 mm. Texas and Colorado., .texanus Horn 

 Punctures toward the elytral base small and sparse, but little larger or 

 stronger than posteriorly; impression of the fifth segment (9) 

 deeper, sharply angulate anteriorly and virtually attaining the base 

 of the segment; body black, much smaller, not so stout; antennae (9 ) 

 very slender, black, but slightly longer than the body, the third 

 joint only very little longer than the fourth; prothorax one-half wider 

 than long, with a rounded swollen glabrous central spot, not visible 

 in texanus, and outside of which over the disk there are some sparse 

 and moderate punctures, the pubescence not dense; elytra two and 

 two-fifths times as long as wide, parallel, together rounded at tip, 

 with small but deep and rather sparse punctures, the cinereous band 

 as in texanus but much more nubilous, the hairs not dense enough 

 to obscure the punctures; abdomen rufescent about the entire pe- 

 riphery except at base; legs extremely short, the hind tarsi nearly 

 one-half longer than the tibiae, being even relatively longer than in 

 texanus. Length (9) 10.8 mm.; width 3.2 mm. Texas (Browns- 

 ville) subtropicus n. sp. 



5 Depression of the fifth ventral segment ( 9 ) deep and sharply marked, 

 broadly obtuse anteriorly and occupying only about apical half of 

 the segment; color piceous, clothed not very densely with cinereous 

 pubescence forming a broad fascia on the elytra from about basal 

 fourth to three-fifths and not at all sharply marked anteriorly, also 

 having throughout the surface small sparse spots of ferruginous; 

 antennae pale, the scape blackish basally; prothorax (9) fully 

 three-fourths wider than long, only a little narrower at base than 

 apex, sparsely and strongly punctured, with a very small flat central 

 glabrous spot, the pubescence only moderately dense, coarse, varie- 

 gated slightly with pale fulvous; elytra with strong and impressed, 

 moderately close-set punctures, whichat basebecomestrongly, densely 

 tuberculiferous, especially toward the humeri. Length (9) 14.0- 



15.5 mm.; width 4.5-5.0 mm. Pennsylvania cingulatus Say 



A Nearly as in the preceding but very pale in color, smaller in size 

 and with the prothorax as wide at base as at apex and only about 

 a fourth wider than long; elytral punctures less coarse and, toward 

 base, coarsely and closely rugose only at and behind the humeri, 

 immediately within which area they are simple, though coarse and 

 sparse nearly to the base thence to the suture, feebly graniferous. 

 Length (cf 1 ) n.8 mm.; width 3.7 mm. New York. 



pallescens n. subsp. 



Depression of the fifth ventral (9) acutely angulate anteriorly and 

 about attaining the base of the segment; body rather shorter and
