io Species of the Atlantic regions 1 1 



Species of the Rocky Mountain, Sonoran and Pacific regions 15 



II Prothorax much wider before the middle than at base 12 



Prothorax but little wider before the middle than at base, less transverse 



and more quadrate 14 



12 Body rather large and stout. Coloration and lustre throughout as in 

 pallipes; head distinctly smaller than in the pallipes section, three- 

 fourths as wide as the prothorax, the eyes large and very prominent; 

 antennae stout and fusco-testaceous, extending distinctly behind the 

 thoracic base ; prothorax two-fifths wider than long, widest near apical 

 third, the sides strongly rounded, becoming oblique and feebly ar- 

 cuate basally; apex sinuato-truncate, with rather distinct though 

 obtuse angles and about as wide as the base, the basal angles broadly 

 rounded; surface pale, with a large transverse nubilous black central 

 area, which is frequently triad or altogether obsolete, the sides rather 

 strongly and not very finely reflexed; stria fine, distinct, subentire, 

 generally more distinct basally; foveae large but very feeble and 

 vague, with rather close-set distinct punctures extending to the 

 sides but nearly wanting medially; elytra one-half longer than wide 

 and a third wider than the prothorax, parallel, rapidly very obtusely 

 rounded at apex, the sides only feebly arcuate; sinus barely trace- 

 able; striae rather fine but impressed, the scutellar long and deep, 

 parallel; intervals moderately convex; discal puncture before apical 

 fourth; hind tarsi three-fourths as long as the tibiae, moderately 

 slender, the fifth joint as long as the first two, the third distinctly 

 longer than wide. Length (d 71 9) 5.8-7.3 mm.; width 2.0-2.6 mm. 

 Virginia, Rhode Island and Vermont to Lake Superior and St. Louis, 

 Missouri. Very abundant. [ Carabus comma Fab., Feronia pallipes 

 and Acupalpus pallipes Say and Dej. nee. Fab.; Ag. dorsalis Lee.]. 



comma Fabr. 



Body much smaller and less stout though similar in coloration and lustre, 

 the broad black sutural region of the elytra similar, generally 

 abbreviated though often attaining the base, the suture similarly 

 always testaceous and generally more pallidly so than in the pallipes 



section; hind tarsi more slender 13 



13 Form elongate-oval, rather convex, shining; head black, with the 

 labrum very pale, rather more than three-fourths as wide as the 

 prothorax, the eyes (cf) large and very prominent, separated across 

 the vertex by barely more than four times their width; antennae 

 fusco-testaceous, stout, extending slightly behind the thoracic base; 

 prothorax as in comma throughout, except that the pallid disk has 

 only an oblong vittiform central blackish spot and the basal angles 

 are not quite so broadly rounded; elytra nearly as in comma through- 

 out and also in relationship with the prothorax, the scutellar stria 

 long, deep and parallel, the black maculation truncate anteriorly at a 

 considerable distance from the base in the type; hind tarsi much 

 more slender, the fifth joint similarly long, the third triangular and 

 one-half longer than wide. Length (cf) 5.7 mm.; width 2.0 mm.
