138 PHEMONE CORDIGER. 



negated on the elytra with numerous small dots of a 

 greyish white pubescence. 



The face and cheeks are covered with a yellowish grey 

 pubescence which gradually becomes blackish towards the 

 vertex and hides the sculpture with the exception of a fine 

 mesial line which is smooth and extends up to the front- 

 margin of the thorax. The antennae are about of the 

 length of the body ; the four basal joints are thicker than 

 the seven apical joints and contrast strongly with them ; 

 the thick joints have a fringe of black hairs on the under- 

 side and are densely covered with a pubescence which is 

 grey on the upper , black or blackish on the underside of 

 the three basal joints; on the fourth joint, the apical 

 half of which is slightly swollen , the pubescence is black 

 with the exception of a ring of grey pubescence at the 

 base; the seven apical joints are almost glabrous and of a 

 testaceous brown colour. The scape is as long as the second 

 and third joint taken together , the fourth joint is dis- 

 tinctly shorter than the third , the fifth about two-thirds 

 of the fourth , the succeeding joints almost inconspicuously 

 decreasing in length. 



The thorax shows irregular transverse wrinkles inter- 

 mixed with some deeply impressed punctures , and has just 

 within the origin of the two divergent white lines which 

 are the continuation of the white A-shaped figure on the 

 vertex of the head , two very fine nearly parallel white 

 lines along the middle not fully extending to the base 

 of the thorax. 



The straight divergent white thoracical lines are conti- 

 nued in slightly curved lines down to the middle of the 

 elytra where they end in a transverse angular white line 

 which makes part of a line that surrounds a broadly 

 heartshaped space occupying the total width of the 

 elytra but not extending to the apex ; the suture is 

 narrowly margined with white , and the elytra are varie- 

 gated with small dots of a greyish pubescence, more spar- 

 sely, however, on the heartshaped space. The elytra are
