T' Apices of elytra not prolonged in the 9 • • centralis Rits. 



S' Outer half of elytra rugose in consequence of

R' The two innermost striae only rather regular. 



U Raised thoracical patches impunctate or nearly 

 so. (Large or moderately large species: 18 l / 2

V Middle of metasternum in the (ƒ glabrous, 

 without a pubescent spot. — Apices of elytra 

 in the 2 rounded. 



W Metasternum pitchy black. Femora and tibiae 



more or less dark pitchy . • fulviventris Kolbe.

X Apices of elytra in the Ç rather bluntly pro-

U' Raised thoracical patches strongly punctured.

V Prothorax broad, raised patches (especially the 

 central one) very distinct, their punctuation 

 being much sparser than that on the surround-

 Y'. Prothorax narrower, raised patches (especially 

 the central one) less obvious, owing to their
