elytra, leaving very minute bare intervals, and there are a very 

 few longer erect setae near the sides. 



The body is moderately elongate and parallel-sided, and rather 

 depressed, with the head broad, the clypeus semicircular and 

 finely granulated, and the forehead coarsely punctate-rugose. 

 The pronotum is short, coarsely and closely punctured, with the 

 sides rounded, the front angles nearly right angles and the hind 

 angles very obtuse. The scutellum is strongly punctured, the 

 elytra densely and conflueutly, and the eostae are rather indistinct. 

 The pygidium is finely coriaceous and clothed with rather long 

 erect hair. The antennae are 10-jointed, joints 3 to 7 regularly 

 decreasing in size. The legs are rather slender, but the hind 

 tarsi a little shortened and thickened ; the front tibise bear three 

 sharp teeth, the uppermost not reaching the middle, minute and 

 separated by a sharp notch from the preceding one ; the longer 

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

 the hind foot more than half as long as the other. 



c? . The front tibia is much more slender than that of the 

 female and the teeth shorter and sharper, the eyes are larger, the 

 abdomen rather long and distinctly arched, and the pygidium 

 very prominent and convex. 



$ . The form is shorter and less parallel-sided, the eyes are 

 smaller, the abdomen is short and very convex, and the pygidium 

 almost concealed.

A. birmanus, var. flavescens, Arrow. 



The elytra are yellow, except a vaguely defined dark sutural 

 stripe of varying size, and the clypeus and the middle, as well as 

 the sides, of the pronotum are generally pale also. 



The specimens of this variety, of which I have seen a con- 

 siderable series taken by Comotto at Minhla, are all of rather 

 smaller size than the typical form. It has also been found at 

 Pakokku, Upper Burma,' 180 feet (iWiss Molesivorih, Sept., Oct.).

332. Adoretus lacustris, sp. nov. (Plate V, fig. 45.) 



Pale testaceous, with the clypeus and tarsi reddish, and the 

 forehead, vertex, two indefinite spots at the front margin of 

 the pronotum, the extreme edges of the elytra, and sometimes 

 the abdomen, black. 



It is a rather large species, moderately elongate, not very 

 convex, and evenly and rather closely clothed with fine uniform 

 decumbent grey hair. The head is not large, the surface granu- 

 lated (not very closely) and the clypeus almost semicircular. 

 The pronotum is moderately finely and closely punctured (but 

 less closely in the middle), with the sides strongly rounded,
