JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, finely and sparingly punctured and clothed with single grey pubescence ; the clypeus not separated from the face, its anterior margin concave ; eyes large, ovate ; antennae extending to the base of the thorax, dentate from the fourth joint, black, the lower three joints fulvous; thorax twice as broad as long, the sides and the posterior angles rather rounded, the median lobe but ^ slightly produced, the surface entirely impunctate, black, shining, tbe extreme lateral margin fulvous ; scutellum black, pointed, broad at the base; elytra finely and rather closely punctured, fulvous, the shoulders with a smail black spot, a larger round spot is placed near the suture at the middle, and a transverse short band, concave at its lower margin, at some distance from the apex, this band does not quite extend to either margin ; the breast and abdomen black, clothed with grey pubescence ; legs rather slender as well as the tarsi. Hab. Ibembo, Congo (Duvivier). (Coll. Belgian Mus. and my own.)

COPTOCEPHALA FALKENSTEINI Karsch, Berl. ent. Zeitsch. 1882, p. 396. This species is a true Peploptera and must be placed in that genus, as several specimens which I received from German East Africa have proved to me. CRYPTOCEPHALIN.E.

Flavous, terminal joints of the antennas black, the head and thorax dark fulvous, the latter with tbe sides and two basal spots flavous ; elytra regularly punctate-striate, flavous, a spot on the shoulder, another near the middle, and a transverse narrow band near the apex, black. Length 5 millim. Of robust, posteriorly slightly narrowed shape ; the head dark fulvous or piceous, fiuely and closely punctured: antennae long, black, the lower five joints flavous, terminal joints elongate and distinctly widened: thorax twice as broad as long, strongly narrowed in front, the sides greatly deflexed, the lateral margin's rounded at the middle, the surface very minutely punctured, the disc piceous or dark fulvous, the anterior margin narrowly, tbe sides more broadly and two large oblique spots at the base, flavous ; scutellum broad, its apex rounded, flavous, the base narrowly black; elytra distinctly narrowed posteriorly, strongly and regularly punctate-striate, flavous, the interstices flat and impunctate, the |
