This genus is composed of moderately large, elongate, duskily 

 colored insects, the majority of the species of which have their ab- 

 domens more or less conspicuously ornamented with orange or red 

 maculations. They are distributed throughout South America from 

 the Isthmus of Panama to northern Argentina. Up to the present 

 time nine, or possibly ten, supposed species have been recognized and 

 described. Two others are now added. These may be separated by 

 the annexed key:
