The total number of species thus known to me is twenty, and 

 these can be readily divided into two groups. 



i. Those having the sides of prothoraK crenulate or dentate, 

 and with the disc of pronotum more or less vermiculate-punctate 

 without larger punctures. 



ii. Those having the sides of prothorax entire, and the disc of 

 pronotum with larger punctures irregularly placed among smaller. 



To this arrangement S. master si Pasc, is a solitary exception, 

 since by its crenulate-sided prothorax it belongs to group i.; while 

 in its having larger punctures on its pronotum it should be in 

 group ii. Its close affinity to *S. major, noticed above, makes it 

 more naturally belong to group i. 



The following tabulation will be of assistance in determining 

 the species. 



Oroup i. Sides of prothorax crenulate or dentate. 



Aj_. Disc of pronotum more or less vermiculate-punctate, with- 

 out larger punctures (except in S. mastersi Pasc). 

 B^ Elytra with alternate intervals catenulate.

1. D 1 . Pronotum strigose without larger punctures... maj or Blackb. 



2. D, 2 . Pronotum punctulate with larger punctures ...mastersi Pasc.
