surface opaculate at the sides of the hind body; head no longer 

 than wide, with notably large though moderately prominent eyes, 

 two-thirds as wide as the prothorax; palpi black, with pale tip; 

 antennae very slender and filiform, fully half as long as the body, 

 fuscous, paler basally, the third and fourth joints equal; prothorax 

 as in all the preceding species in general outline but relatively 

 smaller in size, the transverse impressions feebly traceable; stria 

 very fine but somewhat impressed; foveae small, deep, punctiform 

 and isolated, the attendant impression very small and feeble, only 

 visible by oblique light; elytra relatively more elongate, three- 

 fifths longer than wide and fully four-fifths wider than the pro- 

 thorax, parallel, with feebly arcuate sides, which are rapidly rounded 

 at the humeri; apex gradually ogival, with very shallow sinus; 

 striae rather coarse and deeper internally; intervals there distinctly 

 convex, flat externally; legs rather dark rufous throughout; anterior 

 male tarsi feebly dilated, rather shorter than in any of the preceding 

 species; met-episterna fully twice as long as wide. Length (cf ) 

 8.4 mm.; width 2.8 mm. Louisiana (Alexandria). 



ludoviciana n. sp. 



Strial punctures coarse, strongly crenulating the intervals 6 



6 — Body having nearly the form and size of rufipes Dej., but with the 

 hind body relatively shorter and broader and with more arcuate 

 sides. Upper surface deep black and with varnish-like polish, the 

 under surface also black and highly polished throughout, without 

 trace of the lateral opacity of the preceding species; epipleura and 

 legs very pale; head barely longer than wide, nearly two-thirds 

 as wide as the prothorax, with only moderately large and rather 

 feebly prominent eyes; anterior impressions small and very feeble; 

 palpi piceous, paler basally, the fourth joint distinctly longer than 

 the third; antennae slender, piceous, with the three basal joints 

 testaceous, not quite half as long as the body, the third and fourth 

 joints equal; prothorax of the same general form and surface as in 

 rufipes, the foveae deep, punctiform, isolated and with barely any 

 attendant impression; elytra one-half longer than wide, one-half 

 to two-thirds wider than the prothorax, rather rapidly ogivally 

 rounded at apex, the sinus extremely shallow; humeri not very 

 rapidly more rounded; striae coarse, very deep, the punctures 

 conspicuous; outer striae almost obsolete but having the series 

 of strong punctures almost like the other striae; ninth stria deep, 

 marginal, punctate; intervals notably convex internally; scutellar 

 stria a rather short series of punctures or somewhat impressed; met- 

 episterna only one-half longer than wide. Length (9 ) 8.8-9,0 mm.; 

 width 3.2 mm. Minnesota (Duluth). Also an entirely similar 

 unlabeled specimen from the Levette collection, probably from 



Indiana politissima n. sp. 



A — Deep black color and polished surface as in politissima, the outline 

 slightly less ventricose, much smaller in size, the elytral striae 

 and punctures similar; head similar, the antennae fuscous, paler 

 basally, more slender than in politissima and with distinctly more 

 elongate joints; prothorax similar but with the apex rather less
