The paper of which the following is an abstract, will be published in

The remarkable distribution of this genus of Mantodea is exactly 

 paralleled by that of another genus of Orthoptera, namely Mastax, species 

 of which from the southern slopes of the Peruvian Andes have recently been 

 described by Dr. S. H. Scudder. 



The nearest allies of Chosradodis are the Australian Orthoderas, which 

 its young ' larvte' resemble in the form of the pronotum.
