The present genus is characteristic of tropical America and occurs 

 from southern Mexico to Paraguay and Bolivia. It has been mono- 

 graphed by Redtenbacher, Pictet and Saussure, and Karny. All of 

 these authors have added new forms. In the present paper two 

 additional species are likewise characterized for the first time. Un- 

 doubtedly further collecting in the tropical regions of South America 

 will bring to light still other species. 



The annexed synopsis of the species is modified from H. Karny's 

 table published in his Revisio ConocepJialidarum, pp. 6-7, and includes 

 the two insects described beyond.
