Patrobus longipalpus new species. 



Form elongate-oblong, depressed. Color black, moderately shining, an- 

 tennae, palpi, tibiae and tarsi rufo-piceous. Head one third longer than broad, 

 as wide as the thorax at apex, basal constriction not evident ; eyes moderately 

 prominent; frontal impressions long, deep, extending on the clypeus, a few 

 indistinct rugae behind the eyes ; mandibles prominent ; third joint of the 

 maxillary palpi long, slender, subcylindrical, not wider at apex, one half longer 

 than the second ; terminal joint of the labial palpi shorter and stouter, penul- 

 timate joint bi-setose in front; mentum moderately and broadly emarginate 

 with a short, deeply bifid tooth ; antennae moderately slender, first joint short 

 and stout, less than twice as long as wide, third nearly three times as long 

 as the second, fourth to eleventh shorter, subequal, more than twice as long 

 as wide, two basal joints glabrous. Thorax one half wider than long, as wide 

 at base as at apex, depressed, sides slightly rounded in front with a distinct 

 sinuation or flattening at apical one third, anterior angles slightly prominent, 

 broadly rounded ; oblique behind and broadly sinuate at basal third, posterior 

 angles slightly obtuse, not rounded ; margins moderately wide, edge narrowly 

 reflexed ; basal foveae, broad, oblique, indistinct, strongly rugose, transverse 

 impressions indistinct, coarsely and sparsely punctate and rugose ; base oblique 

 at either side. Elytra three times as long as the thorax and one fourth wider ; 

 basal margin below the disk ; humeri sub-angulate, sides nearly straight and 

 parallel to apical two fifths, thence evenly arcuate to apex ; striae moderately 

 strong, finely and distinctly punctate on basal half, intervals slightly convex; 

 three impressed punctures on the third stria ; sterna sparsely punctate. Legs 

 moderate, femora moderately stout, tibiae scarcely wider, at apex ; posterior 

 trochanters two fifths the length of the femora, with rounded apices. Length, 

 10 mm.; width, 3.5 mm. 1 J. 



Keene Heights, Essex Co., N. Y., 6 July, 1918. (Notman.) 

 This species may be distinguished from P. rugicollis by its smaller 

 size, broader and more rugose thorax and by the long terminal joint 

 of the maxillary palpi, differing from the terminal joint of the labial 

 palpi. It may be distinguished from P. septentrionis by its broad de- 

 pressed and rugose thorax. 



Pterostichus laevilatus new species. 



Form oval, slightly elongate, slightly convex. Color black, strongly 

 shining, elytra dark piceous, slightly bronzed, mandibles, palpi, antennae and 

 legs rufous. Head as wide as the thorax at apex, as long as wide; frontal 

 impressions broad, not deep, rounded and sparsely and indistinctly punctate; 

 palpi subcylindrical, truncate at apex ; mentum with a broad bifid tooth. 

 Thorax one fourth wider than long, three fourths as wide as the elytra, widest 

 before the middle; base equal in width to the apex; sides broadly rounded, 

 strongly sinuate at basal one sixth, thence straight to the sharply rectangular
