neiv species of African Eumolpidce and Halticidce. 99 



The bright flavous colour of the greater part of the tibiae and 

 the tarsi will separate this species from any of its allies. 



PsEUDOCOLASPIS TUBERCULICOLLIS, Td. Sp. 



Black, sparingly pubescent; basal joints of the antennae fulvous; thorax 

 remotely punctured, bituberculate ; elytra strongly punctate-striate ante- 

 riorly, with some white stiff liairs ; femora with a long curved spine. 

 Length, If line. 



Entirely black, shining, the head longitudinally strigose ; antennse short, 

 the last six joints strongly thickened and transverse, black, pubescent, the 

 basal five joints fulvous; thorax long, the sides witlaout margins, the disc 

 with two elongate ridge-like tubercles at the sides, remotely but distinctly 

 punctured, furnished with some white bristle-like hairs ; scutelhim subpen- 

 tagonal, the base with some punctures ; elytra with a transverse basal 

 depression, the shoulders produced into an acute ridge, the surface strongly 

 punctate-striate within the depression, more finely so posteriorly, the inter- 

 stices provided with white stiff erect hairs ; under side strongly punctured, 

 more closely pubescent, the femora with a long curved tooth, the tibiae also 

 with a fine tooth near the apex.

Nerissus gabonensis, n. sp. 

 ' Metallic greenish-black below, sparingly pubescent; the antennae, tibite and 

 tarsi black, above metalUc green ; the thorax closely and strongly punctured, 

 pubescent ; elytra punctured like the thorax, the interstices transversely 

 rugose, clothed with whitish pubescence. Length, 2^ — 3 lines. 



Head rather finely and not very closely punctured, sparingly pubescent, 

 the lateral margms of the clypeus raised ; palpi with pale basal joints ; 

 antennae nearly as long as the body in the male, slender, filiform, black ; 

 thorax transverse, one-half broader than long, the sides rounded and serrate, 

 the surface deeply and closely punctured, sparingly clothed with whitish 

 hairs ; elytra sculptured like the thorax, but the interstices near the base 

 transversely wrinkled ; underside more obscure metallic green ; the flanks of 

 the thorax very strongly, the breast more finely, punctured. 



(Coll. Jacoby.) 



N. gabonensis seems allied to A^. hispidulus, Lefev., but that 

 species is described as bluish or cupreous, of having a mixed 

 white and fulvous pubescence, the latter being also dense. N. 

 strigosiis, Chap., is a much larger species, and has the pubescence 

 of the elytra arranged in rows ; the female of N. gabonensis has 

 shorter antennae, and is of a more broad and shorter general 

 shape. 



HALTICID^. 

 Lactica marginicollis, n. sp. 



Flavous below, reddish-fulvous above ; thorax impunctate, parallel, the 

 sides narrowly margined ; elytra finely and closely punctured. Length, 

 2^ lines. 



Head impunctate, reddish-fulvous, the frontal elevations oblique ; the 

 carina distinct, thickened ; eyes moderately large, rather distant ; palpi 

 robust ; antennae scarcely extending to half the length of the elytra, fulvous, 

 the third joint slightly larger and more elongate than the following joints,
