214 MB. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA [Mar. 6, 



finely and sparingly punctured and clothed with single grey 

 pubescence ; the cl_ypeus 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 entirety impunctate, black, shining, the 

 extreme lateral margin fulvous ; scutellum black, pointed, broad 

 at the base ; elytra finely and rather closely punctured, fulvous, 

 the shoulders with a small 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.) 



The coloration of the thorax and that of the elytra will at once 

 assist in the recognition of this species, of which I have seen two 

 specimens, which were formerly contained in the collection of the 

 late A. Duvivier. The species seems closely allied in coloration to 

 G. foveiceps Lac, but is of more narrowly elongate shape, and the 

 thorax is not fulvous but black. 



CoptocephaI/A 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^:. 

 Cryptocephalus ornaticollis, sp. n. 



Flavous, terminal joints of the antennas black, the head and 

 thorax dark fulvous, the latter with the 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, finely and closely punctured ; antennas 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 margins 

 rounded at the middle, the surface very minutely punctured, the 

 disc piceous or dark fulvous, the anterior margin narrowly, the 

 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 knpunctate, the
