no trace of a humeral angle ; rostrum 

 continuous with the forehead ; scutelluui 

 invisible. 



3 (6). Elytra with the alternate intervals higher 



at the base and the margin itself elevated, 

 the apices separately niucronate ; the 

 scaling of the elytra fused so as to form 

 an apparently calcareous indumentum in 

 which the individual scales are not dis- 

 tinguishable ; the setae minute. 



4 (5). Prothorax subcylindrical, about as long 



as broad ; interval 9 on the elytra not 

 carinate at the base ; rostrum with dense 

 confluent punctation at the sides, which 

 is entirely hidden by scaling lembunculus, Boh. 



5 (4). Prothorax transverse, with sides rounded, 



and much narrower at the apex than at 

 the base ; interval 9 on the elytra strongly 

 carinate near the base; rostrum bare at 

 the sides and there impunctate, except 

 for two shallow punctate striee scapha, Boh, 



6 (3). Elytra with neither the base nor the alter- 



nate intervals elevated, the apices jointly 

 rounded ; the scales on the elytra distinct 

 and overlapping, the setae well-developed 

 and erect on the apical half. 



7 (10). Rostrum much deeper than wide, as broad 



at the base as the forehead, without dorsal 

 furrows in front of the antennte, and 

 with the sides below the scrobes partly 

 squamose ; 4th tarsal joint at least twice 

 as long as 3rd; elytra without a white 

 sutural stripe. 



8 (9). Prosternum with a broad longitudinal im- 



pression in front of the coxiB ; the suture 

 between ventrites 3 and 4 (1st and 2nd 

 visible) entirely obliterated in the middle ; 

 length (without rostrum) 4-4-5 mm. ; 

 elytra with very long erect setae on the 

 apical third longipilia, sp. n. 



9 (8). Prosternum not impressed ; the suture be- 



tween ventrites 3 and 4 distinct through- 

 out and strongly sinuate in the midtlle; 

 length 2'5-3 mm. ; elytra with fewer and 

 much shorter setae on the declivity only. . bevimi, sp. u. 

 10 (7). Rostrum subcylindrical, much narrower 

 at the base than the forehead, with two 

 dorsal furrows from the antennae to the 

 apex, and with the sides below the 

 scrobes entirely bare ; 4th tarsal joint 

 half as long again as 3rd; elytra with a 

 white sutural stripe albosuturalis, sp. n.
