HARPALIN/E 175 



wide as the prothorax, the latter slightly longer, two-fifths wider 

 than long, the sides moderately and evenly converging and very 

 evenly and feebly arcuate from base to apex, the latter deeply 

 sinuate, two-thirds as wide as the base, which is subrectilinearly 

 transverse throughout; anterior angles produced but broadly rounded 

 at their apices, the basal angles somewhat less than right and simply 

 blunt; basal bead entire, nearly flat and shining; surface evenly 

 declivous to the reflexed margin throughout the length as in mernla, 

 the transverse impressions feeble though obtusely evident medially, 

 the stria very fine, not quite entire and the fovese long, linear, feeble, 

 impunctate and not punctiform anteriorly; elytra not quite one-half 

 longer than wide, very little wider than the prothorax, evenly 

 arcuately ogival behind the middle, the sinus very feeble; humeri 

 minutely denticulate at base; striae fine, the scutellar long, the inter- 

 vals almost flat, 3-5-7 with even series of small, distinct and widely 

 spaced punctures, much more extended than usual and almost 

 attaining the middle of the length on all three; hind tarsi with the 

 basal joint as long as the next three. Length (9 ) 11.5-12.5 mm.; 

 width 4.8-5.2 mm. Texas (Austin and Waco) aethiops n. sp. 



8 Body oblong-oval, rather stout, deep black, the pronotum feebly 

 diaphanously pallescent laterally, the under surface and legs black; 

 antennae as in crassns; palpi black, pale at tip; head more developed 

 than in rusticus or crassns, distinctly more than half as wide as 

 the prothorax, the eyes moderately prominent, the foveae small, 

 irregularly perforato-punctiform; prothorax not quite one-half wider 

 than the median length, the sides broadly arcuate and converging 

 apically, much less arcuate posteriorly; apex deeply sinuate, not 

 quite three-fourths as wide as the base, which is nearly as in rusticus, 

 the angles right, with their tips blunt; surface nearly as in rusticus, 

 except that the impunctate foveae are rather more impressed; elytra 

 nearly as in rusticus; hind tarsi ( 9 ) similarly very slender but with 

 joints 2-4 notably less elongate. Length (cf 9 ) 10.2-11.5 mm.; 

 width 4.0-4.8 mm. Virginia to Florida and Texas (Austin). Nine 

 examples merula Germ. 



Body oblong-oval, still stouter than in merula and more densely opaque 

 than any other species, deep black, even the sides of the prothorax 

 not diaphanously paler, the legs and under surface as in the pre- 

 ceding; antennae rather long and very slender, black, the two basal 

 joints abruptly pale testaceous; head well developed as in merula 

 but with much less convex eyes, the foveae very small, abruptly 

 perforato-punctiform but at the anterior end of distinct impressions; 

 prothorax much more elongate, only about a third wider than long, 

 rather densely opaque and wholly punctureless, the sides, apex and 

 surface nearly as in merula but with the foveae rather sharply defined, 

 long, slender, linear and distinct; elytra relatively not quite so broad, 

 subequal in width to the prothorax and only twice as long, the sides 

 gradually rounding behind, the apex still more acutely ogival, the 

 sinus broad and deeper than in any of the preceding; margins with a 

 very few small punctures besides the foveae, which as usual are not 

 interrupted medially; striae strong and rather deep, the scutellar
