The type and only known specimen of this isolated species flew upon my newspaper while on a steamer in Hampton Roads.



The type of this subgenus is one of the most minute of the Athetids, of subparallel and moderately convex form, the mesosternal process very short, not extending to the middle of the contiguous coxæ 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 subequal.

The contiguous coxæ and short mesosternum betoken some affinity with Metaxya and Hydrosmecta, but the antennæ are wholly at variance. There are no visible sexual modifications.



Body long and slender, the facies somewhat as in Metaxya, the middle coxæ very narrowly separated, the mesosternal process short, barely extending to the middle of the coxæ, its apex acute but
