and stouter legs, it differs in the smoother and more even surface 

 of the elytra and the fine simple punctuation of the striee ; the 

 shape of the prothorax is also different owing to its much more 

 strongly rounded sides and the presence of the shallow, but dis- 

 tinct, apical constriction.

Long. 14-16, lat. 5^-7 mm. 



Head convex, closely and finely punctured and with denser 

 whitish scaling ; forehead rather flattened and with a faint central 

 carina ; anteocular furrows absent. Rostrum not incised at base, 

 as long as prothorax, scarcely curved. Upper surface with five 

 narrow carina?, the central one bare and a good deal higher than 

 the others, which are more or less concealed by the denser scaling ; 

 lateral sulci not very deep, subequal, the upper pair meeting at 

 base, which is distinctly higher than the plane of forehead ; scrobes 

 shallow, entii-ely lateral and scarcely oblique ; inferior basal furrow 

 absent. Antennce very long,. with dense white pubescence; scape 

 extending beyond posterior margin of eye ; first joint of funicle 

 longer than second. Prothorax transverse, apex naiTOwer than 

 base, sides strongly rounded, bi^oadest behind middle, apical mai'gin 

 truncate ; ocular lobes almost obsolete. UpiDer surface convex, 

 closely set with low rounded tubercles, leaving a central furrow 

 (without carina) and an ill-defined smooth line on each side ; 

 tubercles bare, without set?e, interstices with dense white scaling. 

 Elytra elliptical in (S , ovate in 5 and acuminate at apex, shoulders 

 sloping, sides rounded, much more so in 5 , broadest about middle, 

 apical processes absent. Upper surface convex, with finely 

 punctured striae which disappear before apex ; the stria? all bare 

 except the 6th, which is faintly visible throvigh the scaling ; 

 all intervals quite plane and with stripes of white scaling ; the 

 stripes on intervals 4 and 6 broadest and most dense ; those on 

 1 and 2 equally dense, but narrower ; those on 3, 5, and 7 still 

 narrower, less dense and less well defined ; the dorsal intervals 

 have each a row of minute dark dots in the white scales, taking 

 towards the sides the form of small and very depressed granules ; 

 inflexed margins of elytra and undei'side of body densely clothed 

 with white scaling. Legs much longer and thicker in S > in 

 which sex the posterior tibiae exceed the apex of elytra by more 

 than I their length, whereas in § they do so by less than | ; 

 scaling dense, uniform white ; posterior tarsi spongy beneath, 

 longer and thicker in S , 2nd joint rather narrower than the 

 others, 2nd and 3rd subequal in length, 1st rather longer.
