54 MEMOIRS ON THE COLEOPTERA. 



apparently very slightly shorter than the prothorax, the apices very broadly 

 and feebly sinuate laterally; abdomen parallel, with very feebly arcuate 

 sides, fully as wide as the elytra, finely, not densely punctate, the fifth tergite 

 rather shorter than the fourth. Length 1.42 mm.; width 0.4 mm. Virginia 

 (Fort Monroe). 



The type and only known specimen of this isolated species flew 

 upon my newspaper while on a steamer in Hampton Roads. 



Phasmota n. subgen. 



The type of this subgenus is one of the most minute of the 

 Athetids, of subparallel and moderately convex form, the meso- 

 sternal process very short, not extending to the middle of the con- 

 tiguous coxae and with its sharply angulate apex finely aciculate, 

 separated from the small but angulate metasternal projection by a 

 very long deep interval, at the bottom of which the longitudinal 

 ridge is very thin and laminiform. The tarsi are moderate, the 

 first four joints of the posterior short and rubequal. 



Atheta (Phasmota) ingratula n. sp. Rather slender, nearly parallel, moder- 

 ately shining, the punctures very minute and rather close-set, sparse on the 

 abdomen, the vestiture rather close and distinct; color pale piceous, the head 

 darker, the elytra paler, the abdomen feebly clouded medially, the legs pale; 

 head nearly as long as wide, the eyes well developed, nearly as long as the 

 tempora, the latter but feebly swollen, the carinse fine though clear and even, 

 entire; antennae short, very slender basally, gradually and rapidly, strongly 

 incrassate distally, the outer joints strongly transverse, the last longer than 

 the two preceding, the second cylindric, much longer than the third, which 

 is strongly constricted basally; prothorax but slightly transverse, only just 

 visibly wider than the head and a little narrower than the elytra, widest 

 anteriorly, the sides feebly arcuate, straighter basally, the basal angles very 

 distinct; surface scarcely impressed basally; elytra somewhat transverse, the 

 suture slightly longer than the prothorax, the apices narrowly and scarcely 

 visibly sinuate externally; abdomen finely, not densely punctate, parallel, 

 only slightly narrower than the elytra, the fifth tergite longer than the fourth. 

 Length 1.22 mm.; width 0.25 mm. Mississippi (Vicksburg). 



The contiguous coxae and short mesosternum betoken some 

 affinity with Metaxya and Hydrosmecta, but the antenna? are wholly 

 at variance. There are no visible sexual modifications. 



Crephalia n. subgen. 



Body long and slender, the facies somewhat as in Metaxya, the 

 middle coxae very narrowly separated, the mesosternal process short, 

 barely extending to the middle of the coxae, its apex acute but
