CARABID/E 4 1 



line fine, not entire; foveae sublinear, moderate in size and depth, 

 continued to the hind angles by a gradually feebly deplanate area; 

 elytra one-half longer than wide and nearly one-half wider than the 

 prothorax, parallel, with broadly arcuate sides and circularly 

 rounded apex; striae fine, feebly impressed, very minutely punctate, 

 except basally, where the punctures become rather strong and twice 

 as wide as the striae; intervals very feebly convex, rather finely but 

 strongly, closely punctate and with short fulvous pubescence; femora 

 rather distinctly though sparsely and unevenly punctate. Length 

 (cf 9 ) 8.0-8.8 mm.; width 2.8-3.2 mm. New York to Iowa. 



[Chlcenius degantulus Dej.; feisthameli Lai.} pusillus Say 



Form more abbreviated, the size much smaller; coloration, lustre and 

 general habitus nearly similar; head relatively larger, nearly four- 

 fifths as wide as the prothorax, similarly punctured; antennae slender, 

 not much over half as long as the body, testaceous, clearer basally; 

 prothorax nearly similar in form and sculpture but more nearly as 

 long as wide, the sides at base becoming straight only at, and not 

 for some distance before, the basal angles, which are distinctly 

 obtuse though sharply marked and not blunt; base becoming ar- 

 cuately oblique at the sides, barely visibly wider than the subtruncate 

 apex; surface not differing markedly, the foveae a little smaller; 

 elytra shorter, two-fifths longer than wide and two-thirds wider 

 than the prothorax, parallel, with broadly arcuate sides, the apex 

 much more rapidly and obtusely rounded; striae still finer and less 

 impressed, similarly but not quite so strongly punctate, the intervals 

 similar but not so closely punctured or pubescent; abdomen with 

 the fine punctures less uniformly distributed; femora less punctate; 

 sterna similarly coarsely and deeply punctured throughout. Length 

 (9)6.3 mm.; width 2.4 mm. Louisiana (Alexandria), nanulus n. sp. 



These species seem to be amply distinct among themselves and 

 doubtless a number of others are already included in collections. 

 The subacute lobes of the labrum, in all the species, have a loose 

 tuft of stiff yellow bristles, which are different from the ordinary 

 setae of the labral apex. 



Brachylobus Chd. 



The mentum in this genus is so radically different from the usual 

 type in this subfamily, that a separate tribe might be organized 

 to include it alone, so far as now known. The surface of the 

 mentum is smooth and has two very deep impressed perforations; 

 the apex has an extremely shallow sinus, with very short angulate 

 lateral lobes and is completely edentate. The following is a sub- 

 species of the well known lithophilus: 



Brachylobus lithophilus ssp. indigaceus nov. Body nearly as in 

 lithophilus in form, size and sculpture, but not quite so stout and not
