294 MEMOIRS ON THE COLEOPTERA 



stria still shorter and feebler; hind tarsi a little shorter than in the 

 female of pallipes, very stout, the fifth joint fully as long as the first 

 two, the third barely at all longer than wide. Length ( 9 ) 6.8 

 mm.; width 2.4 mm. Wisconsin plagiatus n. sp. 



8 Form stout, somewhat as in pallipes, the coloration and lustre through- 

 out nearly as in that species; head black, large, nearly four-fifths as 

 wide as the prothorax, the eyes large and very prominent; vertex 

 without a central puncture in the type; antennae fusco-testaceous, 

 moderately stout, extending about to the thoracic base; prothorax 

 throughout as in pallipes, except that the hind angles are evidently 

 though very narrowly rounded; elytra shorter, less than one-half 

 longer than wide and fully two-fifths wider than the prothorax, other- 

 wise as in pallipes throughout, the scutellar stria rather short but 

 deeply impressed and subparallel; hind tarsi differing greatly, much 

 longer, three-fourths as long as the tibiae, the fifth joint not quite as 

 long as the first two, the third one-half longer than wide. Length 

 (apparently 9 ) 5.0 mm.; width 2.1 mm. Texas (El Paso), Dunn. 



tarsalis n. sp. 



Form much more slender than in any of the preceding and smaller in size, 

 similar to pallipes in lustre and coloration throughout 9 



9 Body small in size, elongate-oval, convex, shining; head notably 

 large, only very little narrower than the prothorax, the eyes large 

 and very prominent; antennae longer, fusco-testaceous, moderately 

 stout, extending well behind the thoracic base; prothorax widest at 

 anterior two-fifths, a third wider than long, the sides broadly and 

 rather strongly arcuate, becoming oblique and straight basally; apex 

 sinuato-truncate, barely wider than the base, the basal angles obtuse 

 but well defined, only very narrowly blunt at their apices; surface 

 throughout nearly as in pallipes, except that the median stria is 

 almost entire; elytra throughout nearly as in pallipes but scarcely 

 more than a fourth wider than the prothorax; hind tarsi rather 

 slender, the third joint much longer than wide. Length (cf ) 5.0 

 mm.; width 1.8 mm. Arkansas.. . vividus n. sp. 



Body small in size, narrowly oval, the anterior parts relatively rather 

 small; head large, five-sixths (c?) to four-fifths ( 9 ) as wide as the 

 prothorax, the eyes large and very prominent; antennae fuscous, 

 paler basally, only moderately stout, extending behind the thoracic 

 base; prothorax rather small, two-fifths wider than long, widest at 

 two-fifths from the apex, the sides rounded, moderately oblique and 

 nearly straight basally, the basal angles obtuse, well defined, finely 

 blunt at their apices; surface pale, with a very large transverse 

 blackish central area as in pallipes, the other features also nearly as 

 in that species, the stria more nearly entire; elytra a little shorter 

 than in pallipes but otherwise similar, two-fifths wider than the 

 prothorax; scutellar stria longer than usual in this section, parallel 

 and deeply impressed, nearly a third as long as the basal thoracic 

 width; hind tarsi moderately slender, concolorous and not darker 

 than the tibiae, the third joint distinctly longer than wide. Length 

 (c? 9 ) 5.0-5.2 mm.; width 1.7-1.9 mm. Texas (Waco).
