Species of African Halticinie and Galerucinss. 15 



indistinctly punctured ; thorax below and the anterior and inter- 

 mediate legs fulvous, rest of the under-side and the posterior femora 

 black, breast and abdomen nearly smooth. 



Hal. Grahamstown, South Africa {Rev. O'Mil). 



Much smaller than C. ijeringueyi, apterous, the elytra 

 pointed, the antennas with tlie terminal four joints dark 

 only. 



Grepidodera mahernensis, sp. n. (Plate III, fig. 1.) 



Below black, above dark metallic-blue, the basal joints of the 

 antennae and the legs fulvous, thorax strongly punctured, with oblique 

 projecting anterior angles, deeply sulcate ; elytra closely and strongly 

 geminate punctate-striate. Length 3 millim. 



Head impunctate, the vertex black, frontal elevations strongly 

 raised, rounded, fulvous like the clypeus and the labrum, antennae 

 long and slender, black, the lower three joints fulvous, basal joint 

 robust, second, one-half shorter than the third joint, fourth and 

 following joints elongate ; thorax transversely subquadrate, the 

 lateral margins rounded at the middle, the anterior angles strongly 

 produced outwards and pointed, the base with a deep sinuate sulcus 

 bounded at the sides by an equally deep perpendicular groove, the 

 surface very strongly but irregularly punctured, tlie space below the 

 sulcus nearly impunctate, scutellum impunctate ; elytra with a 

 rather deep depression below the base, closely and stiongly punctured 

 in double rows, the interstices at the sides longitudinally costate ; 

 breast and abdomen purplish-black, legs fulvous. 



Hal). Malvei^, Natal (C. Barker); also Upper Ton- 

 ga at (C. Barker). 



A well-distinguished species on account of the metallic- 

 blue upper surface, the produced anterior angles of the 

 thorax, and the geminate punctuation of the elytra. The 

 species differs from Deivcrejns, Weise, in its non-narrowed 

 anterior and posterior shape of the elytra, and in having 

 the thoracic sulcus placed at some distance from the base, 

 which is not narrowly raised as in the last-named genus. 



Crepidodera usamharica, Weise (Deutsche Ent. Zeitg. 

 1902). 



A comparison of this species of which Weise kindly has 

 sent me some specimens proves its identity with my C. 

 peringueyi (Tran;^. Ent. Soc, 1905), the insect seems to 

 vary enormously in size, some specimens being twice as
