ClCINDELID/E AND CARABID/E 85 



different, the median lobe not so broad, tumid, more abruptly formed 

 and slightly more advanced, arcuato-truncate; prothorax smaller, 

 fully one-half wider than long, the grooves entire, the marginal 

 broad, the two impressions feebler than usual; elytra oval, with 

 arcuate sides to the base, nearly one-half longer than wide, the 

 surface smooth, with barely a trace of minute punctulation at any 

 part though with irregular polygons of very fine lines, as in many 

 other forms; hind tarsi (cf) evidently longer than the tibiae, which 

 have a moderate brush of stiff testaceous hairs internally at apex. 

 Length 23.5 mm.; width 9.0 mm. New Mexico (Las Vegas), 

 Meeske. A single male example vegasensis n. sp. 



Body similarly decidedly narrow though still more depressed, and with 

 the upper surface so highly polished as to appear varnished, deep 

 black, the side margins rather narrow and with an extremely faint 

 bluish-violaceous bloom; head and mandibles as in the preceding, 

 the labrum different, the median lobe very broad, nearly half as 

 wide as the labrum, not tumid, very evenly and feebly arcuate at 

 its broad apex, not more advanced than the sides, from which it is 

 separated by distinct though rather narrow sinuses; prothorax as in 

 vegasensis, much narrower at base than at apex, scarcely one-half 

 wider than long, the grooves nearly similar, the impressions a little 

 larger and stronger; elytra elongate-oval, with evenly arcuate sides 

 to the base, the surface very smooth, with barely a trace of geminate 

 series apically; hind tarsi (cf ) barely at all longer than the tibiae, 

 which have the usual internal brush of hairs characterizing the males 

 of the elongatus group. Length 26.0 mm.; width 9.0 mm. Kansas. 

 A single male vernicatus n. sp. 



18 Form moderately stout, oblong-oval, strongly convex, shining, 

 black, the side margins black and unusually narrow; head moderately 

 large, the impressions deep, the mandibles (cf) sparsely strigose 

 but only from the tooth to the base; labrum with the median lobe 

 strongly tumid, smooth, only moderately broad, rounded; prothorax 

 not quite one-half wider than long, very much narrower at base 

 than at apex, the lateral and basal grooves uniting at the angles, 

 the sides evenly arcuate; subbasal impressions widely separated, 

 moderate; elytra oblong-oval, rather blunt at apex, two-fifths longer 

 than wide, the sides parallel and feebly arcuate, rounding basally 

 and apically, equal in width to the prothorax as usual, convex, the 

 surface with geminate series of feeble punctures, obsolescent sutur- 

 ally, stronger laterally, the double series separated by lines scarcely 

 visibly elevated inwardly but distinct laterally, the two at the 

 summit of the flanks abruptly strong and conspicuous, confluent 

 at the end of the long humeral carina; hind tarsi (c?) about as long 

 as the tibiae. Length 25.0 mm.; width 9.0 mm. Kansas (Dodge 

 City), Knaus duplicatus Lee. 



Form much stouter, larger in size, rather more alutaceous, deep black, 

 the margins similarly narrow and black; head relatively smaller, two- 

 thirds as wide as the prothorax, the mandibles and labrum nearly 

 similar; prothorax larger and more transverse, convex, three-fifths 

 wider than long, the impressions and grooves nearly similar; elytra
