354 MR. 11. JACOBY OX THE [Mar. 7, 



very closely and distinctly punctured ; elytra strongly punctate-

 fuscous. 



Length 4 millim. 



Of parallel shape ; the head impunctate, obsoletely sulcale in 

 front of tlie eyes ; clypeus separated from the face by a transverse 

 groove, rather deflexed, impunctate, palpi slender; antennae ex-

 four or five joints fuscous, the third joint slender, longer than 

 the fourth one, terminal joints thickened ; thorax twice as broad 

 as long, the sides slightly and evenly rounded, the anterior angles 

 slightly oblique but not produced, the basal margin with a short 

 but deep longitudinal groove, the surface extremely closely and

Bah. Niger-Benue Expedition (Stauclinger). 



I have recei\'ed two specimens of this very distinct species from 

 Dr. Staudinger. 



NlSOTKA TJNIFOBMA, sp. U. 



Pale fulvous, the terminal joints of the antennae darker ; thorax 

 finely and closely punctured, the basal sulci short and deep; elytra 

 closely and finely punctured, the punctation partly geminate- 

 striate. 



Length 3-4 millim. 



Head very finely and somewhat closely punctured, the clypeus 

 with some stronger punctures ; the antennae nearly extending to the 

 middle of the elytra, black, the lower five or six joints fulvous, the 

 third joint slightly longer and more slender than the following two 

 joints, terminal ones thickened ; thorax more than twice as bi'oad 

 as long, the sides straight at the base, rounded at the middle, the 

 anterior angles scarcely oblique or prominent, the perpendicular 

 basal grooves short and deep, the disc rather convex, finely and 

 rather closely punctured ; elytra with closely approached double 

 rows of fine puncttu-es, more or less distinct ; underside and legs 

 pale fulvous.

Although this species seems very closely allied to i\^. ttstacea 

 Chap, and JS^. chapiiisi Jac. from Madagascar, I think it sufficiently 

 diff'erent to be considered distinct. N. testacea, of which the 

 description is scarcely detailed enough, is said to have a dark 

 breast and abdomen, as well as similarly coloured posterior 

 femora.
