Basal cephalic carina distinct, anterior part 

 of prothorax with closely set punctures 

 divided by scabrose intervals ; posterior with 

 remotely set foveate punctures and smooth, 

 raised transverse intervals, a raised line in 



the centre f saga. 



I perplexabilis. 



No raised line in the centre durbana. 



Punctures on the prothorax equal, equi- 

 distant, intervals slightly plicate transversely, 

 especially on the sides. 



Basal cephalic carina sharp, last abdominal 



segment narrow, slightly convex dissimilis. 



Basal carina not sharp, grooved ; last 

 abdominal segment somewhat broad and 

 convex constrata. 



Punctures on the prothorax sub-foveate, 

 equi-distant, intervals smooth, not raised ; 

 basal cephalic carina indistinct rurigena. 



Punctures on the prothorax small, contiguous, 

 very scabrose in the anterior part, a little less 

 closely set in the posterior, a narrow longitu- 

 dinal smooth line in the centre neglecta. 



Punctures on the prothorax not contiguous, 

 but somewhat closely set and with the inter- 

 vals slightly scabrose in the anterior part only plausibilis. 



Punctures on the prothorax sub-foveate, cica- 

 tricose in the anterior part, with the intervals 

 plainly raised there as well as on the posterior, 

 a longitudinal smooth patch in the centre . . ntrina. 



Prothorax with small, somewhat cicatricose 

 punctures, separated by an interval equal to 

 or a little less than their diameter, and with 



a faint median smooth space I citima. 



i valida.

D\ Prothorax either very slightly or not at all ampliated 

 laterally in the middle, and nearly straight thence to 

 the sharp basal angle.-
