120 MEMOIRS ON THE COLEOPTERA 



Subgenus Donesia Csy. 



The small obscure species constituting this group have some 

 tendency in the direction of Metaxya; the following is a second 

 species: 



Atheta (Donesia) restricta n. sp. Subparallel, but slightly convex, 

 somewhat alutaceous, piceous-black, the head and abdomen deeper black, 

 the legs blackish; punctures very fine and close, indistinct because of the 

 fine strong micro-reticulation, which is equally strong on the three an- 

 terior parts but larger though less strong and regularly polygonal on the 

 more shining abdomen, where the punctures are numerous; pubescence 

 very short and indistinct; head rather transverse, three-fourths as wide 

 as the prothorax, the eyes at slightly more than their own length from the 

 base, the tempora swollen and slightly more prominent, rounded, more 

 so at base, the carinse wanting; antennae piceous, rather long and slender, 

 gradually and very slightly incrassate, the second joint much shorter and 

 thinner than the first, the third shorter and more constricted basally than 

 the second, fourth to tenth subsimilar in form though increasing very slowly 

 in size and scarcely visibly shorter than wide throughout, the last small, 

 slender, not as long as the two preceding; median line of the upper surface 

 strongly impressed from the centre to the base; prothorax one-half 

 wider than long, parallel, the side feebly arcuate, more rounding and 

 converging at apex, the median line finely and deeply impressed throughout 

 the length; elytra moderately transverse, scarcely visibly wider though a 

 third longer than the prothorax; abdomen subparallel, with straight sides, 

 narrower than the elytra, the fifth tergite longer than the fourth, the 

 sixth ventral rather prominent and almost circularly rounded in the type; 

 middle coxae subcontiguous, the mesosternal process not extending beyond 

 their middle and with its extremely finely aciculate tip separated from 

 the transverse and very broadly angulate metasternum by a very long 

 deep interval; first three joints of the hind tarsi subequal, the fourth a 

 little shorter. Length 2.0 mm.; width 0.42 mm. Virginia (Fort Mon- 

 roe). 



Differs from temporalis in its slightly longer, more filiform and 

 less incrassate antennae and relatively narrower and not at all 

 rufescent elytra. 



Subgenus Nemota Csy. 



As form and proportion are only relative terms, it was after study- 

 ing some very slender species that I stated the outline in this genus 

 to be "rather stout." When compared with Atheta proper, how- 

 ever, the form of the body is notably slender. The subgenus is 

 peculiar in having the metasternum transverse and never materially 

 projecting anteriorly, being allied in this way to Metaxya and 

 Hydrosmecta, but the middle coxae are not contiguous and the 

 antennae and the general habitus of the body quite different.
