 or but slightly metallic pfasinus, Bob., p. 102. 



10 (9) Humeral fold not forming a pro-

13 (10) Elytra without erect setae. 



14 (15) Elytra with a whitish sutural 



stripe and a broad yellow discal 

 stripe on each, the outline of the 

 posterior declivity straight or 

 slightly convex perroteti, Boh., p. 104. 



15 (14) Elytra with grey scaling which 



is paler laterally, the outline of 

 tlie posterior declivity distinctly 



sinuate acutipennis, Boh., p. 105. 



10 (13) Elytra with short erect setse hispidus, sp. n., p. JGO. 



17 (12) Elytra not impressed on the de- 



clivity. 



18 (19) Elytra Avith the basal margin only 



v-ery slightly raised, the external 

 angle (as seen from above) form- 

 ing an obtuse angle ; rostrum 

 with a broad dorsal impression 

 in addition to the furrow lividus, sp. n., p. 100.

 stripe ; the seta3 as sparse on in- 

 terval as on the disk ; male

 the middle and gradually sloping 

 behind ; setae on the first two 

 ventral segments short and flat- 

 tened ; male organ with marked 

 coriaceous sculpturing, the ape.x 

 sharply pointed cretaceus, Est., p. 107. 



22 (21) Elytra with the longitudinal cur- 



vature less convex, deepest near 

 the base and becoming abruptly 

 steeper on the posterior declivity ; 

 setae on the first two ventral seg-
