308 Mr. Charles J. Gahan on new 



portion of the disk less densely punctured and without ridges. 

 Elytra thickly and strongly punctured, with the punctures gradually 

 becoming smaller and sparser posteriorly. Body underneath brassy 

 green, impixbescent, scarcely punctured ; abdomen with a golden 

 tinge. Legs black, with the clubs of the four anterior femora 

 reddish chestnut. The tarsi above with a greyish pubescence, 

 which on the posterior tarsi is silvery. Prosterual process feebly 

 obtusely tubercled and subvertical behind. Antennae black, shorter 

 than the body. 



A single female exami)le in the collection. The species 

 is easily distinguished by the peculiar punctuation of its 

 elytra. In no other species of the genus do we find the 

 punctures anteriorly so strong, and posteriorly so sparse. 

 The shortness of the antennie (in the female) is also a 

 very distinct character. 



Calliclwoma fidujineiim, n. s. 

 = Callichroma abyssiniciim, Chev. MS. 



Nigrum, subtus sub-seneum ; antennis chalybeatis, articulis 

 o — 6 interdum rufis ; pedibus rufis, chalybeato-tinctis ; capite 

 rugoso-punctato ; prothorace dorso regulariter et transversim stri- 

 goso ; elytris opacis, nigro-fusco tenuiter velutinis ; antennarum 

 articulo 4o quam 3o vix breviori. Long. 15 — 23 mm. 



Hab. Abyssinia and W. Africa ?. 



Prothorax regular, armed on each side with a sharp conical 

 spine, the disc nude, sub-nitid, crossed by fine ridges running into 

 each other, and all with a fairly regular transverse direction. 

 Elytra dull, with a brownish black faint pubescence. Antennte 

 steel-blue, with sometimes the joints o — 6 reddish ; with the 

 fourth joint as long as {3'), or scarcely shorter than ( J ), the third. 



A species easily recognised by the regular transverse 

 ridges on the whole of the upper side of the prothorax, 

 and the dull brownish black colour of the elytra. Its 

 structure brings it nearest, perhaps, to the North Indian 

 C. pcrhetiim, white. There are fourteen specimens in the 

 Brit. Museum collection. Two specimens in Mr. Bates's 

 collection are ticketed W, Africa, but Mr. Bates considers 

 the correctness of this locality open to question. 



Hexarrhopala {Cleomenince) , n. g. 



Head deeply enough concave between the antennal tubercles. 

 Front declivous. Muzzle short. Eyes finely facetted, emarginate.
