Ti/pe in Ur. Ohaus' collection. 



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 being divided by 

 a sharp notch and more widely separated than 



Adoretuhirratipcs. ^'^e first and second ; above the uppermost 

 tooth the outer edge is nnely serrated, 1 he 



longer claw of the front and middle feet is cleft, and the shorter 



claw of the hind foot is more than half the length of the longer ; 



the hind tarsi are short and thick. The antennae are 10-jointed, 



joints 2 to 5 progressively diminishing. 



The sexes scarcely differ superficially, but the eyes are rather 



larger in the male. 



Length, 10-5-12 mm. ; breadth, 5-6 mm.
