with the first joint brown. Prothorax with four very small 

 tubercles on the disc, two before and two behind, the latter more 



widely separated ; marked 

 with a median impressed line ; 

 covered faintly with a very 

 short grevish pubescence. 

 Elytra faintly pubescent, sub- 

 nitid, distinctly and rather 

 closely punctured ; narrowed 

 gradually from the base to 

 within a short distance of the 

 apex, then slightly dilated ; 

 each sharply rounded at 

 the apex. Body beneath 

 brown, with a faint covering 

 of silvery-grey pubescence. 

 Legs brownish, the peduncles 

 of the femora and the base 

 of the tibiae pale testaceous. 



2 . Antennae less than twice 

 the length of the body, entirely testaceous red ; almost the 

 whole of the head and a broad median band along the pronotum 

 testaceous ; the pale sutural band of the elytra extending almost 

 to the apex ; the legs entirely testaceous. 

 Length 10-12 ; breadth 2|"mm. 

 Hob. Ceylon. 



The difference in colour that marks the female specimen here 

 described is probably not altogether sexual, but due in part to 

 individual variation. In the male specimens seen, there is an 

 evident tendency to variation in the extent of the darker brown 

 colour.

Head nearly flat between the antenniferous tubercles, the latter 

 depressed transverse, with the margin entire; eyes divided each 

 into two widely separated parts, the upper much smaller than the 

 lower. Antennae slender, sparsely setose, nearly twice as long as 

 the body in the S . Third and following joints subequal, or very 

 gradually decreasing in length. Prothorax oblong-ovate or some- 

 times almost cylindrical in form, constricted at the base, armed with 

 a small inconspicuous spine at the middle of each side, which is 

 sometimes absent ; somewhat flattened or depressed on the disc. 

 Elytra longer than head and prothorax combined, narrowed poste- 

 riorly and rounded at the apex. Intercoxal part of prosternum
