I have examined all of the Javanese species described by Doctoi^ 

 de Meijere, but only one of them has been received from the Philip- 

 pines. The only other Philippine species known to me are the two 

 described below. 



Xenosapromyza, new subgenus 



This subgenus is distinguished from Saproniysa by the presence of 

 one or two strong bristles near middle of mesopleura much like those 

 in the genus Trypaneoides. but other respects it agrees closely with 

 Safrom.ijza. 



Subgenotype. — Lauxania cinctipes de Meijere. 



SAPROMYZA (XENOSAPROMYZA) CINCTIPES (de Meijere) 



Lauxaiiia cinclipoi de Meijeue, Tijdschr v. Ent., vol. 53, p. i2'). 1910. 



I have seen only tlte type specimen of this s])ecies. from Java. 

 Doctor Frey records the species as a Homonevni from Los Banos, 

 but I think erroneously.
