four thickly papillose underneath in both sexes, the fifth long, very 

 slender, claws also long, slender and simple. 



The genus is also represented in the West Coast of Africa (Sierra 

 Leone, Guinea, Eio Grande), and in India (Pondichery) , Ceylon, 

 and Java.

Chestnut brown, shining ; elytra with a U-shaped flavescent band 

 on each side of the apical part ; head plane on the vertex, frontal 

 part punctured, each puncture bearing a long seta, no impression on 

 the vertex ; basal joint of antennae deeply punctured, densely pubes- 

 cent, transverse joints pilose on both sides but more densely on the 

 upper ; prothorax twice as broad as long, a little rounded laterally, 

 with the edges densely ciliate all round, smooth on the upper part, 

 finely grooved longitudinally in the middle, the groove interrupted 

 at an equal distance from base and apex, and rather plane than 

 convex ; elytra elongato-quadrate, smooth with a few short, seriated 

 flavescent hairs on the discoidal part, denser and longer laterally ; 

 pygidium not very declivous, moderately punctured and very briefly 

 pubescent ; legs with moderately dense punctures bearing a long 

 flavescent bristle. Length 13-15^- mm. ; width 6J-7 mm.

Cerapterus concolor, Westw., 

 Proc. Linn. Soc, ii., 1849, p. 55. 



Closely allied to the preceding species, but differentiated by the 

 shape of the antennae, which are not quite so long, not curved out- 

 wardly at all, and the transverse joints of which are more separated 

 from one another than in C. Smithi ; the head and prothorax are 

 alike, and the elytra also, but the U-shaped apical patch is sometimes 

 hardly distinguishable or entirely absent. 



G. concolor, Sch., given in the Munich Catalogue, as well as in 

 Raffray's list, as a variety of C. Smithi, might prove to be identical
