10 Memoirs on the Coleoptera 



pressions moderate; sides strongly reflexed, the foveae as usual; 

 elytra three-fifths longer than wide, nearly twice as wide as the 

 prothorax; oblique apical sinus distinct; sides abruptly reflexed, 

 rather gradually rounded basally, the humeral angulation distinct, 

 the elevated sinuous basal bead strong, entire; striae deep, smooth, 

 the intervals strongly convex; anterior of the dorsal punctures of 

 the third near the third, the second and third at the second, stria; 

 three basal joints of the anterior male tarsi equal in width, parallel, 

 the third three-fifths longer than wide. Length (cf) 13.0 mm.; 

 width 4.7 mm. Pennsylvania. [Platynus angustatus Dej.]. 



angustatus Dej. 



Dorsal punctures of the third interval four in number as usual in this 

 group 7 



7 — Body a little broader though longer than in angustatus and not quite 

 so convex, similar in coloration and lustre; head similarly narrower 

 than the prothorax, more rhomboidal, the neck relatively longer 

 and not so thick, the eyes a little larger, notably more convex and 

 prominent; frontal indentations between the eyes obsolete; antennae 

 very long and slender, ferruginous, piceous basally, fully two-thirds 

 as long as the body; prothorax longer, very distinctly elongate, 

 otherwise nearly as in angustatus though rather less widely reflexed 

 at the sides and with barely traceable median stria, this being dis- 

 tinct in the preceding; base a little narrower, not quite as wide as 

 the apex, the angles similarly rounded; elytra more elongate, fully 

 three-fourths longer than wide, about twice as wide as the prothorax. 

 otherwise nearly as in angustatus but with four punctures on the 

 third interval, the first subbasal at the third stria, second submedial 

 at basal third, the third and fourth at the second stria; anterior 

 tarsi of the male nearly as in the preceding. Length (cf) 14.0 mm.; 

 width 5.0 mm. Pennsylvania cervicalis n. sp. 



Body smaller, still flatter, with narrower anterior parts and more in- 

 tensely black coloration, very shining; legs piceous-black, the tarsi 

 dark rufous; head much elongated, rhomboidal, only a little nar- 

 rower than the prothorax, the eyes moderate but convex and 

 prominent; tempora but feebly converging to the relatively broad 

 neck; front without pallid spots, the minute interocular indentations 

 distinct; antennae long, very slender, ferruginous, piceous basally; 

 prothorax distinctly elongate, widest near apical third, the sides 

 strongly reflexed, broadly and moderately arcuate, feebly sinuate 

 before the rounded basal angles; base slightly narrower than the 

 apex, which is unusually feebly sinuate; anterior impression deep, 

 the posterior obsolete medially, the stria rather deep; foveae as 

 usual; elytra nearly flat, one-half longer than wide, somewhat more 

 than twice as wide as the prothorax, the oblique apical sinus very 

 feeble; striae smooth, deep, the intervals strongly convex, the third 

 with four punctures, the anterior adhering to the third, the other 

 three to the second, stria; ocellate sublateral punctures closer 

 posteriorly as usual. Length (9) 12.0 mm.; width 4.5 mm.
