lead us to believe that they may live in galls (possibly as inquilines). 
The larvae of certain species are extremely interesting biologically, 
since they reproduce by pedogenesis and are, moreover, very amen- 
able to laboratory conditions.

“Messrs Kunstler and Chaine in Comptes Rendus Hebdomadaires des 
Séances et Mémoires de la Sociéte de Biologie, 1902, v. 54, p. 535, give 
the characters of a form reared from bananas as follows: Tarsi biarticu- 
late, the first segment longer than the second; wings with two or three 
long veins, the two first 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 Necrophlebia Skuse and Chastomera Skuse are appar- 
ently closely related to this American genus and are provisionally associated 
therewith.
