1904.] AFRICAN PHYTOPHAGOUS COLEOPTERA. 251 



large; antennae long and slender, flavous, the seventh joint 

 genei'ally piceous ; thorax scarcely one half broader than long, 

 slightly narrowed anteriorly, the sides feebly rounded, anterior 

 angles slightly produced outwards, the disc rather closely and 

 strongly punctui-ed, fulvous, with two longitudinal large black 

 patches ; scutellum impunctate ; elytra scarcely perceptibly de- 

 pressed below the base, strongly punctate-striate, the punctures 

 distinct to the apex, the suture narrowly and a broader discoidal 

 stripe, occupying tire third to the sixth row, black, this stripe is 

 abbreviated at some distance from the apex ; femora robust, 

 armed with a strong tooth. 



Hub. Beira, E. Africa (^1. ShepjKird). 



Evidently closely allied to E. nuhiensis Har. and of nearly 

 simiilar coloration, but the underside black, the elytra withoiit 

 black margins, the thorax equally strongly punctured. In some 

 specimens the discoidal stripe is separated anterioi-ly into two 

 spots or only indicated ; these specimens are very pale in coloration 

 and probably immature. JJJ. semivittatus Jac. has a greenish and 

 very closely and finely punctured thorax and entii-ely fulvous 

 legs. E. vittatus Gestro has differently coloui-ed antennae, an 

 unspotted thorax and black legs, the base of the femoi-a rufous. 



Mexius brevicornis, sp. n. (Plate XYII. fig. 11.) 



Dark fulvous ; the apical joints of the antennae black, the latter 

 short ; thorax transverse, rather remotely punctiired ; elytra 

 oblong, strongly punctate-striate, the interstices more or less 

 convex ; femora dentate. 



Length 4 millini. 



Head very sparingly and finely punctured, with a short central 

 groove, eyes surrounded by a deep sulcus, clypeus separated from 

 the face by a shallow groove, palpi flavous ; antennae short, the 

 lower seven joints flavous, the rest black, the second joint as long 

 as but thicker than the third joint, terminal joints slightly 

 thickened ; thorax nearly twice as broad as long, of equal width, 

 the sides rounded, the angles acute, the disc convex, strongly and 

 i-emotely punctured ; scutellum smooth ; elytra oblong, subcylin- 

 drical, deeply punctate-striate, the interstices longitudinally 

 convex ; femora dentate ; pi-osternum broad, without sulcus. 



Hah. Beira, E. Africa. 



Of more oblong shape than is the case with most other species 

 of the genus ; the thorax not narrowed or deflexed anteriorly to 

 any extent, and the antenna? shorter than usual. 



Stagrus pulvimanus, sp. n. 



Subc^dindrical, dark greenish aeneous ; the basal joints of the 

 antennae, the knees, tibiae, and the tarsi (partly) fulvous ; head 

 remotely, thoi-ax finely punctured ; elytra very strongly punctate- 

 striate, the intei-stices at the sides costate. 



Length 4 millim. 



Head strongly and remotely punctured, with a short central
