as at apex, slightly more than two thirds the width of the elytra ; slightly 

 emarginate at apex, the sides moderately arcuate in front, oblique and just 

 perceptibly sinuate behind ; posterior angles obtuse ; transverse impressions 

 strong, indistinctly rugose ; median line strong, distinctly impressed, abbre- 

 viated at either end, basal f oveae large, bistriate ; posterior angles strongly 

 carinate ; side margins rather broad with reflexed edges. Elytra one half 

 longer than wide, humeri indistinctly angulate, sides sub-parallel to the middle 

 thence broadly and evenly arcuate to the apex ; striae fine, entire, impunctate, 

 the fifth strongly at apex, the sixth and seventh obsolescent, the eighth not 

 distinct from the margin, intervals slightly convex basally on the disk; the 

 third stria with the first dorsal puncture slightly more than one third from the 

 base, the second slightly less than one third from the apex. Length 4 mm., 

 width 1.25 mm. 1 <J\

This species resembles B. grapei somewhat in form. The elytral 

 striation is that of B. planiuscitlum and B. simplex. In Hayward's 

 synopsis it would be placed in the group planatum and would be dis- 

 tinguished from quadrifove olatum Mann, and mceklini Lee. by its 

 narrower thorax. In Col Casey's revision it should probably be 

 placed next viator (Mem. Col. VIII, p. 31) from which species it 

 would differ by its narrower and differently shaped thorax and en- 

 tirely impunctate elytral striae. 



The specimen was collected among sparse grass on a muddy sand 

 bar. 



The relationship of the following two species are shown in synoptic 

 form: 



A. Legs pale ; size very small. 



B. Head alutaceous ; elytra uniform in color musicola Hayw. 



BB. Head not alutaceous ; elytra with basal and basal half of side margins 



ruf o-testaceous semicinctum Ntm. 



(Bull. Bkln. Ent. Soc. XIV p. 129) 

 AA. Legs dark ; size moderately small. 



B. Form broad ; thorax H wider than long ; elytra piceous. 



quadratulum n. sp. 

 BB. Form elongate ; thorax % wider than long ; elytra black.

Bembidium quadratulum new species. 



Form short, sub-parallel, strongly convex ; color black slightly aeneous, 

 strongly shining; basal joint of the antennae, the legs and elytra dark piceous;
