Mr. Kirhy (Cat. Odon. p. 22, 1890) has placed hcvmatodes under 

 Crocothemis, but the prothorax, with the neuration, indicates it to 

 be a Sympetrum Newm. (^Diplax Charp.). To the same genus belong 

 also Diplax pacificus Kirby, later placed by him in Trithemis, and 

 Tri. rubra Kirby, and these two may perhaps be nothing more than 

 small individuals of ha'inatodes.
