This species varies iu the degree of smoothness or opacity of its surface, which is sometimes microscopically rugulose or shagreened, but except in this respect I have found no difference between specimens from localities so far apart as the Andaman Islands and the Punjab. Wliether this variation is local, I have not seen a sufficient number of specimens to determine ; but in the shape of the aedeagus there is remarkable variation, wliich is almost certainly geographical. I have figured those of three specimens, show^ing a progression from the slightly-cleft typical form occurring in the Eastern region to a very deeply-cleft form in the Western. Fig. 32 is from an Andaman Island specimen, fig. 31 from one from the Chittagoug Hills, and fig. 30' from the United Provinces (Dehra Dun). 338. Adoretus serratipes. (Plate V, fig. 18.) Adoretus serratipes, Arrow, Ann, Mag. Nat. Hist. (8) xiii, 1914, p. 595. Uniformly dark brown, evenly clothed all over with minute grey setae, the vertex of the head and the prouotnm faintly metallic. It is moderately elongate, parallel-sided and rather convex. The head is closely rugose, the clypeus large,, with its margin semicii'cular and strongly reflexed. The pronotum is closely but very coarsely punctured, the front angles nearly right angles, and the hind angles almost rounded off. The scutellum and elytra are strongly, densely and confluently punctured, and the costae of the latter almost obsolete. The front tibiae are armed with three sharp teeth, the second and third
