1881.] PHYTOPHAGOUS COLEOPTERA. 443 



Head very distantly, clypeus closely punctured, aureous ; mau- 

 dibulsB robust and rather long. Antennae of half the length of the 

 body, fulvous, the joints elongate, but slightly thickened. Thorax 

 convex, rather long, about twice as broad as long, the sides very 

 rounded, surface finely and rather closely punctured, metallic green, 

 vpith a faint cupreous tint near the posterior angles. Scutellum as 

 broad as long. Elytra elongate, convex, slightly narrovred at the apex, 

 the base distinctly swollen ; surface much more strongly punctured 

 than the thorax, the punctures arranged in almost regular rows, 

 interstices at the sides slightly transversely wrinkled. Anterior 

 legs very elongate. 



One specimen, contained in my collection. 



The elongate anterior legs, very remote and fine punctuation of 

 the head, and the nearly regular rows of punctures of the elytra 

 will make this species recognizable amongst its allies ; it is distin- 

 guished from G. thoracicum, Lefev., by the rufous tarsi, and the basal 

 elevation of its elytra. 



10. COLASPOSOMA MELANCHOLICUM, Sp. nOV. 



Oblong-ovate. Dark seneous ; antennae black ; above closely 

 punctate, rugose, covered with whitish pubescence, each elytron with 

 four or five longitudinal obsolete costae. 



Length 3 lines. 



Hab. Transvaal. 



Head closely rugose-punctate, with a smooth central line. An- 

 tennae black, extending to one third the length of the body, third 

 and following joints of nearly equal length. Thorax narrowly 

 transverse, nearly three times as broad as long, convex, and its 

 sides deflexed ; surface very closely rugose and punctate, and 

 covered with thin white pubescence. Scutellum not covered with 

 hairs, punctured. Elytra convex, rounded posteriorly, rugose and 

 punctured like the thorax, and pubescent like *he latter, each elytron 

 with four or five longitudinal costae from the base to the apex, at 

 which place they closely approach each other. Underside and legs 

 of the same colour, and pubescent like the upper surface. 

 One specimen is contained in my collection. 



There seem to be several species closely allied to the present one 

 — C. vestitum, Thoms., C. pubescens, Lefev., and C. subcostatum, 

 Gerst. From the first it is distinguished by the transverse thorax 

 and by the colour of its antennae and legs, from the second by the 

 elytral costae and greater size, while the pubescence separates it from 

 the third species. 



11. COLASPOSOMA VARIABILE, sp. nOV. 



Oblong. iEneous below ; above metallic green ; head with two, 

 thorax and elytra with four longitudinal dark purplish bands. 

 Var. Entirely greenish or brownish £eneous. 

 Length 4-41 lines. 

 Hab. Zanzibar. 



Head deeply and closely punctured, dark purplish, a central lon-
