1890.] COLLECTED BY MR. BONNY. 643 



larly punctured ; scutellum with a few fine punctures ; elytra about 

 one third broader than and fully four times as long as the prothorax, 

 parallel, a little flattened on the disc, coarsely striate-punctate from 

 the base to the apex, the punctures oblong in shape and becoming 

 finer towards the suture and larger and deeper towards the sides, the 

 interstices very minutely and very sparsely punctured, flat on the 

 disc, moderately convex towards the sides, the shoulders very little 

 swollen and not prominent ; beneath very shining, bright metallic 

 green, with golden and cupreous tints, the propleurse, the sides of 

 the meso- and metasternum, and the metasternal episterna very 

 coarsely punctured, the rest of the surface (the fifth ventral segment 

 excepted) sparsely and minutely punctured, the ventral segments 

 also longitudinally aciculate, the fifth thickly and rather coarsely 

 punctured ; prosternum horizontally produced behind, its posterior 

 face vertical ; legs moderately long, golden-cupreous, with greenish 

 tints in certain lights. 



Length 15, breadth 4| millim. ( 2 .) 



One example. Apparently closely allied to S. quadraticolle and 

 S. puncticolle, Thorns., from the Gaboon, but not agreeing satis- 

 factorily with the brief and very imperfect descriptions of either of 

 these species. 



Xanthothopeia, Makl. 



Xanthothopeia aruwimensis, sp. n. (Plate LVI. figg. 7; 

 7 a, antenna.) 



Elongate, rather convex, subparallel ; bronze-black, the head 

 violaceous in front and greenish in the middle and at the sides 

 anteriorly, the elytra greenish-seneous and opaque, the head, pro- 

 thorax, and scutellum shining. Head distinctly foveate in the 

 middle between the eyes, finely and sparsely punctured, a longitu- 

 dinal space down the middle smooth ; the eyes comparatively very 

 large, not prominent ; palpi bronze-black ; antennae dark violaceous, 

 short, extending a little beyond the base of the prothorax, the joints 

 from the fourth greatly dilated and flattened and becoming very 

 much wider outwardly, 4-7 subtriangular, 6-10 strongly transverse, 

 9 and 10 each about twice as broad as long, 11 narrower and 

 scarcely longer than 10 ; prothorax convex, transverse, the sides 

 converging from the middle and slightly rounded anteriorly, feebly 

 sinuate before the base, with the lateral carina very fine and 

 extending only from the apex to about the middle and thence to 

 the base replaced by a finely impressed line, the apex finely margined 

 on either side, immarginate in the middle, the base sharply grooved 

 within, the hind angles acute and outwardly directed, the anterior 

 angles declivous, the disc very feebly transversely depressed on 

 either side at the middle and with a deeper transverse impression 

 lower down nearer the lateral margin, the surface finely, deeply, and 

 closely punctured ; scutellum very finely and sparsely punctured ; 

 elytra about one third wider than and fully four times as long as the 

 prothorax, parallel to about the middle, crenate-striate from the base
