punctures scattered or fine and remote. 



(6) 3. Large or medium-sized species, 4 to 5 lines. 

 Tliorax very closely punctured. 



(5) 4. Larger ; metathorax, looked at from above, pos- 

 teriorly sharply truncate, its angles prominent 

 and with theii- margins considerably raised ; 

 5 with the abdomen more shining ; 2nd and 

 following segments scarcely punctured ; ^ with 

 the, thorax more hairy, and the legs darker . . cylindricus. 



(4) 5. Smaller ; metathorax not so sharply truncate ; 

 angles not prominent and scarcely margined ; 

 2 with the abdomen very closely and finely 

 ijunctured on the 2nd and following segments ; 

 (J with the thorax less hairy, and the legs 

 lighter albipes.

(8) 9. Smaller ; in J metathorax bounded by a very 



indefinite ridge ; basal segment of abdomen in
