OLIGOEXOPLUS. 301 



Hind femora extending by nearly a third of their length past the 

 apex of the elvtra. 



Variation. Elvtra sometimes devoid of the posterior black spot. 

 This condition has been met with in only one specimen, the largest, 

 out of four which I have seen. In this specimen also the antennae, 

 elytra and legs are darker ; the first antennal joint only is ferru- 

 ginous, the rest dark brown. 



Length 5J-9 ; breadth 1-2 mm.

Head, prothorax and greater part of the elytra testaceous ; head 

 covered in front with ashy-white pubescence ; prothorax with a 

 border of ashy-white pubescence at the base, along the lower part 

 of each side, and the lateral part of the front margin ; elytra 

 marked each with two spots and two oblique bands of ashy-white 

 pubescence ; the spots discal, one at the base, the other at rather 

 less than one-third from the base ; the bands placed one at about 

 one-third, the other at one-sixth from the apex, both extend from 

 the outer margin to the suture the first produced anteriorly as a 

 narrow band along the suture, the second a little widened at the 

 suture ; the elytra dark brown between the bands and also from 

 the posterior band up to the apex. Body beneath dark brown, 

 entirely or nearly covered with dense ashy-white pubescence ; 

 antennae and legs testaceous, the clavate portion of the hind 

 femora brown. Head and prothorax densely and finely, the elytra 

 more strongly punctured. Third antennal joint subequal in length 

 to the fourth. Hind femora extend by nearly a third of their 

 length past the apex of the elytra in the d" .

Head slightly raised on each side between the antennae ; front 

 vertical, subquadrate. Antennae somewhat distant at base, as long 

 or nearly as long as the body in the c? , a little shorter than the 

 body in the $ ; third and fourth joints spined at the apex, 

 the spines sometimes almost obsolete ; third joint much longer 

 than the fourth. Prothorax not longer than broad, narrowed at 

 "base, very slightly narrowed in front. Elytra feebly sloped behind, 

 either truncate or somewhat rounded at the apex, each with a 

 feeble, obtuse, dorsal elevation at the base ; the shoulders some-
