posterior angles ; anterior angles rounded, not prominent, apex slightly 

 emarginate ; basal f oveae broad, shallow, coarsely punctate, strongly bistriate, 

 inner striae longer, angles strongly carinate ; transverse impressions indistinct ; 

 median line, strong, abbreviated before and behind ; side margins narrow with 

 narrowly reflexed edge, the usual two setae on either side at posterior angles 

 and apical one fourth. Prosternum not margined at apex. Elytra two and 

 one half times as long as the thorax; two thirds longer than wide, widest at 

 middle, slightly wider than the thorax at base, humeri sub-dentiform ; sides 

 strongly and evenly rounded from humeri to apex ; striae strong and distinctly 

 punctate, outer striae less distinct, scutellar striae very short ; two small punc- 

 tures on the second stria, one slightly before the middle and the other at 

 apical one fourth. Metasternal side-pieces short, slightly longer than wide. 

 Three basal joints of the posterior tarsi grooved on the outer side. Length, 

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

This species seems closely related to the species of the subgenus 

 Omasens. The short metasternal side-pieces and short scutellar striae 

 would associate it, however, with the species tumescens, obscurus and 

 ventralis of section B of the third division of Leconte's synopsis. The 

 strongly oval, somewhat ventricose elytra and indistinct outer striae 

 also indicate a relationship with these species. The bipunctate second 

 elytral striae would distinguish it from either of these groups.

This species, recently described by Casey (Mem. Col., VIII, p. 

 302), is recorded by him from Rhode Island (Boston Neck) and 

 Long Island (Huntington and Wyandanch) — Schott. 



Platynus imitans new species. 



Form oblong, subdepressed. Color piceous, palpi, antennae, legs and mar- 

 gins of the thorax pale rufo-piceous ; impunctate, shining. Head longer than 

 wide, three fourths as wide as the thorax, as wide as the thorax at apex; 

 frontal impressions broad, shallow, indefinite ; antennae long, slender, reaching 

 the middle of the elytra, outer joints four times as long as wide, pubescence 

 beginning on the fourth joint. Thorax as long as wide, as wide at base as 

 apex, three fifths as wide as the elytra, apex distinctly emarginate, base 

 arcuate ; sides broadly and evenly arcuate from base to apex ; anterior angles
