The tlircc species of Gonomyia described by de Meijere as 

 Atarbce (Tijd. xvov Entbmol.; vol. 44, 1911) are all members of the 

 subgenus Leiponeura Skusc. These species are Gonomyia nebiilosa 

 (I.e., p. 42, fig. 2,i); pilifera (I.e.; p. 43, fig. 26) and diffusa (I.e.; 

 p. 43, 44). They have nothing in common with Atarba and are 

 quite distinct from any members of the Leiponeura group, that I 

 know of, in tlieir clouded wings. G. insiilensis differs from all of 

 the at:o\e species in its inimarketl wings. 



Genus Erioplera Meigen., 

 Subgenus Acyphona Osten-Sacken. 

 Of this subgenus, two species were included, both of which are 

 herein characterized as new. The only described Pakearctic 

 species, Acyphona maculata Meigen, of Euroi)e, tliffers from the 

 Japanese species, as follows: Wing pattern, in maculata large, 

 rounded brown markings mostly with grey centers; the l;od\-sha<le 

 is much lighter in maculata and there are se\eral imiiorlant dilTer- 

 ences in hvpopvgial characters, ihcse being sf.own b\ the following
