244 SUMATRAN COLEOPTERA. 



Length, from the top of the aiitermary tubers to the 

 end of the elytra , 20 mm. ; breadth at the shoulders 7 mm. 

 — Black, with the antennae (the scape excepted) dark 

 brown. Head , thorax , under surface of body , and legs 

 (with the exception of the tarsi which show a bluish grey 

 pile) densely covered with a pale ochreous pubescence , va- 

 riegated with bare dots which are irregularly confluent on 

 the sides of the abdomen; the antennae are likewise co- 

 vered with a pubescence which is pale ochreous on the 

 scape and 3rd joint , but more greyish on the basal- , brown 

 on the apical half of the succeeding joints. The elytra are 

 variegated with irregular spots of a very dense pale ochre- 

 ous pubescence, which spots are more or less confluent 

 in a transverse direction, so as to form three very irregu- 

 lar bands, one across the base including the densely pu- 

 bescent scutellum , the 2nd before , the 3rd behind the 

 middle ; moreover the elytra are sprinkled all over with 

 small dots of a looser but similarly coloured pubescence. 



The sculpture of the head is concealed by the pubes- 

 cence, with the exception of an impressed mesial line ex- 

 tending from the front margin up to the front margin of the 

 thorax. The head is triangularly concave between the an- 

 tennary tubers which are prominent and, at their base, 

 only separated by the smooth mesial line. The cheeks are 

 as high as the inner orbit of the lower lobe of the eyes, 

 the face subquadrate, broad but not transverse. The an- 

 tennae twice as long as the body ; the scape as long as 

 the 6th joint and gradually thickened on the outside be- 

 hind the middle , which conformation gives it a somewhat cur- 

 ved appearance ; the cicatrix rather large, pubescent, not com- 

 pletely margined at the inside; the 3rd joint the longest, 

 the 4th slightly longer than the 5th, this latter slightly 

 longer than the 6th which is equal in length to each of 

 the succeeding joints, the apical one excepted which is 

 nearly as long as the 3rd. 



The thorax has one frontal and two basal grooves pa- 

 rallel with the margins; the disk is somewhat uneven and
