Geoit a. 



In this group the malps have a pubescent space of greater or 

 less extent near tlie tip of the middle tibiae. This is usually on the 

 outer edge, but sometimes in front of the tibit^. The liasal line and 

 side margin of the elytra unite at the humerus to form either a dis- 

 tinct angle or a regular curve ; and ' " l)asal line anguLate at hu- 

 merus '' and "basal line curved at humertus" are temis used to 

 ilesignate the two modes of union.
