DIURUS TA.RSATUS. 213 



pubescent; the 2nd to 8th joints have the outer apical 

 angle produced , the 9th is obtusely pointed at the tip and 

 rather strongly curved ; the first joint is somewhat longer 

 than the 2nd which is half as long as the 3rd; the 3rd 

 to 7th gradually decrease in length ; the 8th is equal in 

 length to the 7tli , the 9th twice and a half as long as 

 the 8th. 



The sides of the prothorax are very convex; it is wi- 

 dest about the middle , slightly narrowed towards the base 

 and strongly contracted anteriorly ; the uppersurface is den- 

 sely covered with large punctures and provided along the 

 middle with a shallow furrow which disappears near the 

 contracted front portion ; moreover the pronotum shows 

 three longitudinal lines of dirty white scales , whereas a 

 few smaller scales are scattered over the surface. 



The elytra are slightly narrowed in straight lines from 

 the shoulders to the apex; they are regularly foveate (the 

 foveae on the sides are considerably larger than those on 

 the disk), and provided along the suture with a broad 

 band of dirty white scales; this band is strongly contracted 

 between the base and the middle and between the middle 

 aad the apex, and incloses just at the middle a rounded 

 scaleless space; moreover a line of white scales is present 

 along the lateral margins. The tails are rather straight 

 and parallel and as long as the head and rostrum taken 

 together. 



The undersurface is covered with broad and narrow 

 white scales, which are very densely set along the sides. 

 The two basal segments of the abdomen are shallowly im- 

 pressed along the middle ; the 4th segment is very short 

 and contracted. The legs are covered with narrow scales 

 and scale-like setae. The anterior tarsi are dilated; the 

 basal joint is equal in length to , if not longer than the 

 succeeding joints taken together , and as well as the se- 

 cond joint densely fringed with long black hairs.
