MARMAROGLYPHA SUMATRANA. 205 



yellowish, tinted with black towards the tips. The head 

 with the three basal joints of the antennae and the basal 

 half of the 4th , the thorax , scutellum , under surface of 

 the body and the legs covered with a pale ashy pubes- 

 cence ; on the apical half of the 4th joint of the antennae 

 the pubescence is black; the elytra glabrous but varied 

 with pale ashy spots and white lines. The head with an 

 oblique line of a paler pubescence below the eyes. The 

 thorax with large naked points, and provided on each 

 side with a line of white pubescence , commencing at the 

 front margin and continuing over the elytra at the sides 

 to the middle of their length , where it curves inwards , 

 and joins, though indistinctly in consequence of its being 

 repeatedly interrupted, the scutellum; a narrow line of 

 more closely set ashy hairs is present along the middle of 

 the disk. The scutellum densely covered with ashy hairs, 

 leaving however a mesial line free. The elytra covered with 

 small spots of an ashy pubescence; these spots are elon- 

 gate, even linear, at the base, but rounded towards the 

 end ; besides the continuation of the white prothoracic lines , 

 a slightly curved similar transverse line is present across 

 the middle of the apical half. 



The head shows a few dispersed punctures , and a me- 

 sial line which is deeply impressed between the antennary 

 tubers. The antennae reach beyond the apex of the elytra; 

 the scape is sub-cylindrical , the 3rd joint twice as long 

 as the scape , the 4th shorter than the 3rd , slightly si- 

 nuate, enlarged towards the tip, the 5th and following 

 joints slender, gradually decreasing in length, the 11th 

 however longer than the 10th. 



The thorax slightly narrowing towards the front margin , 

 covered with large but shallow naked punctures. The scu- 

 tellum transverse. 



The elytra covered on the basal half with slightly trans- 

 verse glossy granules, which are gradually replaced by 

 punctures becoming less and less marked towards the api- 

 ces which are sub-truncate.
