1899.] PHYTOPHAGOUS COLEOPTERA OP AFRICA. 343 



joint piceous above ; thorax twice as broad as long, the sides nearly 

 straight, obliquely narrowed, with a narrow reflexed and thickened 

 margin, posterior margin oblique near the angles, rounded at the 

 middle, the sui'face very strongly and irregularly rugose and deeply 

 punctured, flavous, the sides with a transverse piceous spot ; 

 scutellum smooth, piceous ; elytra com-ex, extremely closely and 

 deeply punctured throughout, flavous, the suture narrowly dark 

 green, a broad longitudinal band of the same colour extends from 

 the middle of the base nearly to the apex and is rather more 

 distantly placed from the suture than from the lateral margin ; 

 breast and legs more or less piceous, the abdomen and the posterior 

 femora fulvous, the latter very strongly incrassate, their upper and 

 basal portion piceous. 



Hah. jN'iger-Benue Expedition. 



I received a single specimen of this vei'y distinct species from 

 Herr Bang-Haas. 



CEdionychis sulcicollis, sp. n. 



Testaceous, the labrum and the intermediate joints of the 

 antennse black ; head and thorax impunctate, the latter with a 

 distinct transverse sulcus ; elytra obscure fuscous, strongly and 

 closely punctured. 



Length 6 millim. 



Head impuuctate, the vertex swollen, frontal elevations broad, 

 strongly raised as well as the clypeus, labrum black, palpi sv^'ollen ; 

 antenute slender, the lower and the apical two joints testaceous, 

 the third and the following joints equal, nearly twice the length of 

 the second joint ; thorax more than twice as broad as long, the 

 sides strongly rounded, with a very broad flattened margin, the 

 angles in shape of a small tooth, the surface with a deep transverse 

 sulcus near the base, impunctate or with a few very flne punctures ; 

 elytra slightly widened towards the middle, with a rather broad 

 reflexed margin, darker in colour than the thorax, strongly and 

 closely punctured throughout, the interstices more or less wrinkled, 

 especially so at the sides ; below and the legs testaceous ; posterior 

 tibiae with a strong spur, the metatarsus short, claw-joiat strongly 

 inflated. 



Hah. Cameroous {Conrad). 



This species is well distinguished by the deep thoracic sulcus and 

 the strong elytral punctation. I have received a single specimen 

 from Dr. Kraatz, another is contained in that gentleman's 

 collection. 



CEdiontchis apricana Jac. 



Of this species, a most variable one in regard to coloration, I 

 have received specimens from Mashonaland and Natal, obtained by 

 Mr. Guy Marshall. They vary much in size and have the elytral 

 humeral spot sometimes connected with the black suture beloAv 

 the base, so as to include a flavous round spot of the ground- 

 colour ; the antennae and legs are either entirely black or more or
