deep ; first three segments finely impressed at base, the impressions becoming 

 almost obsolete near the sides ; fifth a little longer than the fourth. Legs 

 moderate ; posterior tarsi long, filiform, shorter than the tibiae, with the first 

 joint not thicker but distinctly longer than the next two. Length 3.8 mm. ; 

 width 1.3 mm. 



New York. 



A fine species, somewhat suggestive of the subgenus Zyras, but 

 with much less coarse and dispersed elj^tral sculpture. One speci- 

 men, apparently female. 



M. planifer n. sp. — Moderately stout, subparallel, polished throughout, 

 rufo-piceous, the elytra darker except near the humeri ; abdomen black, the 

 first two segments in great part, and the third narrowly at the margin, 

 pale ; legs pale throughout ; antennae fuscous, pale toward base ; head finely, 

 sparsely, the pronotum still more finely sparsely and obsoletely, punctate, the 

 latter with the flattened median area sparsely biit strongly and asperately so ; 

 elytra finely but strongly, sparsely, subasperately punctate, more strongly 

 but scarcely more densely toward the scutellum ; abdomen subimpunctate, 

 except very obsoletely and remotely along the apical margins ; pubescence 

 fine, sparse, rather more distinct on the under surface of the abdomen. Head 

 much wider than long, four-fifths as wide as the prothorax ; eyes moderate, 

 at nearly their own length from the base ; antennae stout, strongly incrassate, 

 longer than the head and prothorax, the basal joint stout, nearly as long as 

 the next two, third longer than the second, obconical, twice as long as wide, 

 four to seven increasing in width, seven to ten subsimilar, rather compact, 

 subparallel, nearly one-half wider than long, eleventh conical, as long as the 

 two preceding. Prothorax transverse, three-fifths wider than long, widest at 

 apical third where the sides are distinctly rounded to the apex, plainly con- 

 vergent and straight — from above — in basal two-thirds ; base and apex equal, 

 the former strongly, the latter very feebly, arcuate ; basal angles obtuse but 

 not blunt; disk with a lai'ge flattened median region, the median line finely 

 but distinctly impressed. Elytra transverse, two-fifths wider but only just 

 visibly longer than the prothorax ; sides feebly divergent and arcuate from 

 the humeri, which are rather broadly exposed ; disk slightly impressed near 

 the sides behind the middle. Abdomen rather longer than the anterior parts, 

 quite distinctly narrower than the elytra ; sides parallel, slightly arcuate 

 behind ; border thin and deep ; first two segments widely and deeply impressed 

 at base, the third finely and very feebly so ; fourth and fifth subequal. Leijs 

 slender ; posterior tarsi much shorter than the tibiae, with the basal joint as 

 long as the next two. Length 3.2 mm. ; width 1.0 mm. 



North Carolina (Asheville). 



The description is evidently drawn from the male, and in the 

 female the asperate flat median area of the pronotum is probably 

 wanting in great part ; the male has, in addition, the sixth tergite 

 feebly emarginate and unevenly serrulate, a somewhat more isolated
