Gen. Fœnus, Fabr.
1. Fœnus gracilis. F. niger, facie lateribusque thoracis argenteo pilosis; pedibus anticis et intermediis pallidè rufo-testaceis, tibiis posticis basi tarsisque albis; abdomine subtùs rufo-testaceo.
Female. Length 6 lines. Black; subopake; the face, sides of the thorax and beneath with silvery pubescence; the mandibles, palpi, and scape in front rufo-testaceous. Thorax: the anterior and intermediate legs rufo-testaceous, the femora having a darker stain above; the posterior legs black, with the base of the tibiæ and the tarsi white. Abdomen rufo-testaceous beneath; the ovipositor white at its apex.

Gen. Stenophasmus.
Head globose; antennæ longer than the body, and very slender and setaceous; the prothorax forming a slender neck; the anterior wings with one marginal and three submarginal cells; the femora slightly incrassate, not denticulate; the tarsi 5-jointed. Abdomen petiolated, the petiole as long as the abdomen; the ovipositor as long as the petiole and abdomen united.
This genus is founded on the examination of a single individual, which in general appearance exactly resembles the smaller species of the genus Megischus; on examination, however, it will be found that it differs from that genus in the neuration of the anterior wings; its femora are not denticulate, in which character it differs from both Megischus and Stephanus; with the latter genus it agrees in having 5-jointed tarsi.
1. Stenophasmus ruficeps. S. niger; capite et antennarum basi rufis; ovipositore tarsisque pallidè testaceis; petiolo abdominis cylindrico; alis subhyalinis.
Female. Length 5 lines. Black, slightly shining; head globose, red and sprinkled with white hairs, and delicately striated transversely. Thorax sprinkled with white pubescence above, the sides more thickly clothed with the same; above, the thorax is transversely rugose, on the metathorax becoming more regularly striate; the metathorax has a central longitudinal carina and also one on each side; the legs sprinkled with erect white hairs; the tarsi pale rufo-testaceous with the claw-joint black; wings subhyaline, with a broad light-fuscous stain along the centre of the anterior pair; a hyaline streak crosses them at the base of the stigma. Abdomen: the petiole as long as the thorax, narrowest at the base of the abdomen; it is rugose at the base; the ovipositor pale testaceous.
