Densely covered all over with fawn-coloured scales, except on 

 the rostrum in Q, apex of rostrum in <£, and a small space 

 between the front coxae in both sexes; apical segments of 

 abdomen with darker scales. Prothorax with the sides, apex 

 and middle fasciculate, the fascicles consisting of masses of small 

 scales in which numerous stout ones are placed. Each elytron 

 with a fasciculate crest on 3rd interstice, commencing near base, 

 interrupted at its middle and terminated at summit of posterior 

 declivity, 5th interstice with a small fascicle near base and 

 another near apex, sides with small subfasciculate masses of 

 scales; suture between crests at summit of posterior declivity 

 with a small darker velvety patch, the patch terminated by a 

 feeble (but distinct) v-shaped ridge. Undersurface with a few, 

 the legs with numerous suberect scales. 



Broad, depressed. Rostrum rather feebly curved and coarsely 

 punctate in £, more strongly curved and feebly punctate in Q. 

 Antennae thin; scape the length of funicle, inserted one-third 

 from apex of rostrum in ^, two-fifths in £; 2nd joint of funicle 

 thinner and slightly longer than 1st; club elliptic. Prothorax 

 strongly transverse, sides dilated and slightly elevated, apex pro- 

 duced and scarcely half the width of base, base bisinuate, disc 

 uneven; densely punctate. Scutellum feebly raised, subquadrate. 

 Elytra wider than and raised above prothorax, base trisinuate, 

 shoulders feebly rounded, sides parallel to near apex; striate- 

 punctate, punctures concealed, striae feebly traceable. Femoral
