(also having a basal black band) ; the colour of the antennae is not 

 given, but only the last joint is mentioned as being black ; other 

 detailed particulars in regard to structure are absent. Of the 

 present insect I have seen three or four specimens kindly sent by 

 Mr. Marshall. ^ 



MONOLEPTA NIGEO-OENATA, sp. n. (Plate XXI. fig. 12.) 



Rufous; the antennae (the last two joints excepted) and the 

 tibiae and tarsi flavous ; thorax finely and closely punctured ; elytra 

 of similar sculpture, rufous, a broad transverse band at the base 

 and another below the middle black. 



Length 5 millim. 



Of similar shape and size as the preceding species, also of nearly 

 similar coloration ; the head with a few minute punctures, rufous*; 

 the antennae long and slender, flavous, the apical two joiuts black, 

 the second and third joints small, equal, the fourth as long as the 

 basal one ; thorax twice as broad as long, of usual shape, finely 

 and closely punctured, rufous, shining ; scutellum rufous ; elytra 

 punctured like the thorax, the base wkh a transverse black band, 

 similar to the preceding species, and another baud below the middle 

 of the same width but of rather rounded shape near the suture ; 

 below and the femora fulvous, the tibiae and tarsi flavous. 



Hab. Malvern, Natal (G. Marshall). 



I have received several exactly similarly coloured specimens of this 

 species, which differs, besides the coloration, in the less transversely 

 shaped and rufous, not flavous, thorax. 



MONOLEPTA OCTOMACrLATA Jac. 



Of this Monolepta several specimens obtained at Frere, Natal, 

 have been sent by Mr. Marshall, in which the elytra are entirely 

 without spots ; they differ in no other way whatever from the type, 

 but may be known by the black vertex of the head and the similarly 

 coloured tarsi and breast. 



Monolepta citeinella, sp. n. 



Elongate, convex, pale greenish flavous ; the head and the breast 

 pale fulvous ; antennae long and slender ; thorax and elytra ex- 

 tremely minutely punctured ; legs slender. 



Length 4-4| miUim. 



Head broad, obscure pale fulvous, scarcely perceptibly punctured, 

 the frontal elevations indistinct, the clypeus rather strongly raised 

 between the antennae ; the eyes large and round ; antennae nearly 

 extending to the apex of the elytra, flavous, the terminal two or 

 three joints fuscous at the apex, second and third joiuts small, 

 equal, the basal and the other joiuts very elongate and slender ; 

 thorax nearly twice as broad as long, the lateral margins perfectly 

 straight, the posterior margin rounded, anterior angles slightly 

 obliquely truucate, the disc microscopically punctured ; scutellum 

 pale fulvous; elytra very closely and slightly more distinctly 

 punctured than the thorax, convex, the sutural margin rather
