long as the body, fuscous, clearer testaceous basally; palpi testa- 

 ceous, the last two joints black; prothorax almost as long as wide, 

 with arcuate and moderately reflexed sides, slightly more oblique 

 basally, the angles broadly rounded; margins distinctly more 

 reflexed at base, the foveae linear, distinctly impressed, smooth, 

 extending through basal two-fifths; base about equal in width to the 

 apex, which is distinctly sinuate; elytra oblong-suboval, barely 

 one-half longer than wide, one-half (cf) to three-fourths (9) 

 wider than the prothorax, the subparallel sides unusually arcuate; 

 apex gradually rounded, with very feeble sinus; striee rather fine, 

 sharply grooved, smooth, feebly impressed; intervals slightly 

 convex internally, the third with four or five punctures; met- 

 episterna one-half longer than wide; anterior male tarsi very pale, 

 slightly dilated. Length (cf 9 ) 6.4-7.0 mm.; width 2.4-2.8 mm,

 finely diaphanous; under surface black, the epipleura piceous, the 

 legs paler, rufous; head rather elongate, much narrower than the 

 prothorax, the eyes large but not prominent; antennae slender, 

 more than half as long as the body, the basal joint dark rufous, the 

 next three black, the remainder pale brownish-ferruginous; pro- 

 thorax fully as long as wide, the sides moderately rounded, more 

 oblique but still arcuate posteriorly, moderately reflexed, rather 

 broadly so at base, the angles broadly rounded; foveae linear but 

 very broad and shallowly impressed; median stria fine, entire, 

 feebly impressed; apex as wide as the base; elytra elongate-oval, 

 slightly more than one-half longer than wide, one-half to two-thirds 

 wider than the prothorax, gradually and subevenly rounded behind, 

 with evident sinus; striae fine, smooth, slightly impressed; intervals 

 feebly convex internally, virtually flat in the female, the third with 

 four or five small punctures; anterior male tarsi moderately dilated, 

 with the joints unusually elongate-oval, bistriate above as well as 

 along the sides. Length (d^ 9 ) 7.0-7.4 mm.; width 2.3-2.6 mm.

Color black, the elytra, epipleura and legs pale rufous; surface shining; 

 form narrower than in the preceding; head elongate-rhomboidal, 

 much narrower than the prothorax, the eyeg rather large and 

 slightly prominent; antennae very slender and filiform, fusco- 

 testaceous, clearer at base, almost two-thirds as long as the body; 

 palpi pale, the last two joints infuscate; prothorax as long as wide, 

 or wider (9 ), the sides subevenly arcuate and rather finely reflexed, 

 somewhat more so at base though not at all conspicuously; basal 

 angles broadly rounded; median stria fine, subentire; foveae rather 

 small, linear, broadly and feebly impressed, smooth; base and apex 

 about equal, the latter very moderately sinuate; elytra three-fifths 

 longer than wide, two-thirds to four-fifths wider than the prothorax, 

 gradually rounding behind, with the sinus extremely faint; striae
