trifurcate from the base, the maculation frequently faded, the disk 

 becoming wholly pale 5 



5 Basal angles of the prothorax very narrowly rounded or blunt, though 

 always obtuse; elytral black spot produced anteriorly along the 

 suture 6 



Basal angles very broadly rounded; elytral black spot truncate anteriorly, 

 not suturally prolonged; scutellar stria much more developed; head 

 smaller 10 



6 Hind tarsi very stout basally, the third joint not or but slightly longer 

 than wide 7 



Hind tarsi much less stout to notably slender, though always tapering, the 

 third joint much longer than wide 8 



7 Body rather stout, convex, oblong-oval, shining, rufo-testaceous, the 

 head piceous-black, the middle of the vertex feebly pallescent, the 

 antennal triangle pale; pronotum with a large transverse central 

 blackish area, the elytra with a large common oblong black area, 

 produced anteriorly though seldom attaining the base and with the 

 sutural interval rufo-piceous; under surface black, except the sides 

 of the prosternum and the epipleura; legs very pale; head smooth, 

 large, but little narrower than the prothorax, the vertex sometimes 

 with a median puncture; eyes large and very prominent; antennae 

 stout, obscure testaceous, extending to the thoracic base; prothorax 

 two-fifths wider than long, widest a little before the middle, the 

 sides rounded, becoming oblique and straight posteriorly; apex trun- 

 cate, with very obtuse obliterated angles and a little wider than the 

 base, which is arcuato-truncate, with obtuse but rather well defined 

 angles, which are only slightly blunt at their apices; surface strongly 

 declivous laterally, the edges very finely reflexed; median stria 

 distinct but anteriorly abbreviated, the obsolete anterior impression 

 punctureless; base sparsely but strongly punctured from side to 

 side, more obsoletely medially, the fovese vague and feeble; elytra 

 one-half longer than wide and two-fifths wider than the prothorax, 

 parallel, with distinctly arcuate sides and subcircularly rounded apex, 

 the sinus vestigial; striae deeply impressed, the scutellar short though 

 generally distinct, deep; intervals convex; discal puncture behind 

 apical third; hind tarsi very stout, piceous, the fifth joint fully as 

 long as the first two. Length (cf 9) 5.3-6.6 mm.; width 2.0-2.35 

 mm. North Carolina (Asheville) to St. Louis and Keokuk, Mis- 

 sissippi, Louisiana and Texas (Waco and El Paso). Abundant. 

 [ Carabus pallipes Fabr. ; Ag. lecontei Chd.] pallipes Fabr. 



Body stout, more ventricose, the elytra broader, the anterior parts 

 relatively smaller than in pallipes; coloration similar but more pallid 

 throughout in the type; piceous-black spot of the elytra shorter 

 than in the preceding and still more widely separated from base and 

 apex; head piceous, large, four-fifths as wide as the prothorax, the 

 prominent eyes not quite so large as in the preceding, the antennae 

 similar; prothorax almost uniformly piceo-testaceous in the type, 

 less transverse, a third wider than long, otherwise nearly as in 

 pallipes throughout; elytra in outline and striation nearly as in 

 pallipes but fully one-half wider than the prothorax, the scutellar
