% Kunstler and Chaine [Coinpt. Rend Soc. Biol. (1902), 54, 535], give the 

 characters of a form reared from bananas as follows: Tarsi biarticulate, 

 the first segment longer than the second; wings with two or three long 

 veins, the first two branched; palpi quadriarticulate. It was referred to 

 the Heteropezinae though no name was proposed and is presumably related 

 to Heteropeza Winn, and Monodicrana H. Lw. 



§ The Australian Necrophlehia Skuse and Chastomera Skuse are ap- 

 parently closely related to this American genus and are provisionally as- 

 sociated therewith.
