DIURUS ERYTHROPUS. 211 



gles; the narrowed portion of the rostrum is short (so- 

 mewhat more than half as long as the basal portion), 

 glossy and finely punctured. The antennae, which are con- 

 sequently more approximate to the apex of the rostrum 

 than to the front margin of the eyes , are more slender 

 than those of furciUatus and about as long as the head 

 and rostrum taken together; the 4th joint is a little lon- 

 ger than the 3rd, the 3rd a little longer than the 5th, 

 the 6th to 8th subequal , the club but little shorter than 

 the 5th to 8th joints taken together; the eight basal joints 

 are not densely covered with pale yellow setae; the three 

 apical joints or club slightly thickened and finely pubescent. 



The prothorax is similarly shaped as in furciUatus ; its 

 uppersurface is irregularly covered with large punctures or 

 pits and marked on each side with a longitudinal line of 

 large white scales ; moreover a few small scales . are scat- 

 tered over the surface. 



The elytra are decidedly narrowed at and slope rapidly 

 to the apex ; they show narrow longitudinal costae , the 

 interstices between which are foveate; on the 5th and 6th 

 interstices these foveae are very large and strongly trans- 

 verse ; those of the 3rd and 4th interstices bear large white 

 scales which forpi two longitudinal lines ; on the streak 

 between these lines a few similar scales may be observed 

 about the middle, between the middle and the base and 

 on the apical declivity ; moreover a line of white scales is 

 present along the lateral margins. The tails are about 

 as long as those of furciUatus but much more approximate ; 

 moreover their inner margins are straight and parallel; 

 the tails are provided with white scales and dirty yel- 

 low setae. 



The undersurface of the body is marked on each side 

 with a narrow band of large white scales extending from 

 the anterior margin of the prothorax to the apex of the 

 abdomen , whereas broad and narrow scales are scattered 

 over the middle. The legs are sparingly covered with white 

 scale-like setae.
