82 SEEEICOENIA. 



rugulose, with a few minute shining granules ; the sculpture of the clypeus is rather 

 coarser ; in the female the front is slightly coppery, less dull and with the shining 

 granules more distinct ; the top of the head is finely longitudinally strigose. The 

 thorax has the extreme lateral margins coppery ; in the middle of the base there is a 

 slight triangular impression ; the surface is transversely strigose ; the striae are closer 

 together at the base than in front, where they are curved ; the posterior ridge is 

 strongly marked, nearly straight (viewed from above), and terminates abruptly rather 

 before the middle. The elytra have the subcosta distinct to near the apex ; the 

 surface is almost uniformly asperate ; the sutural impression has some very short 

 inconspicuous golden pubescence ; before the middle the pubescence is thicker and 

 forms a not very conspicuous elongate spot. The underside of the insect is clothed 

 with pale grey pubescence, except the abdomen. The prosternum is closely and finely 

 rugulose in the male, rather coarsely rugose and less pubescent in the female. The 

 metathoracic episterna are closely and finely punctured ; and pubescent, except the 

 inner border. The abdomen is shining, with the punctuation very fine and not close.

The head is densely and finely rugose in the male, with numerous shining points ; in 

 the female it is more coarsely rugose. The thorax is convex, nearly parallel at the 

 sides, but suddenly narrowed at the base ; rugose, with curved rugse on the disc ; there 

 is a very slight impression in the middle of the base ; the posterior ridge is very 

 well marked, shining, nearly straight when viewed from above. The elytra are rather 

 strongly rugose, except near the apex where the sculpture is finer, becoming coarse 

 again at the extreme apex ; the subcosta is well marked ; the sutural region is sparsely 

 pubescent, the basal half suffused with green ; the apex is very slightly dilated, each 

 elytron being obliquely truncate on the inner side and on the outer side so that the 

 apex is angular. The prosternal chin-piece is much rounded in front, and, with all the 

 sterna and base of the abdomen, densely and finely punctured and clothed with pale 

 grey pubescence. The inner half of the metathoracic episterna is less densely punc- 

 tured and less pubescent. The apical portion of the abdomen is shining, very delicately 

 and not closely punctured. The posterior tibia? are linear, with a very fine even fringe 

 of short hair on the apical half of the upper edge.
