A REVISION OF THE CHIROMYZINI (DIPTERA).

(Plates xxix.-xxx.) 



INIiss Inviu Smith's paper on the hirva uf Mtin/joiiia rKhrirepf Macfiiiart, has 

 made it necessary to study the genus and its allies in a more comprehensive 

 manner than has been done hitherto, so that the position of the species may be 

 adequately determined and the genus may be disting-uished from the allied genera 

 of the World . 



The literature on the group of StrntioniijiiiUie, here placed in the tribe Chiro- 

 myzini, shows considerable disagreement of ideas concerning the relative value 

 of characters hitherto used for grouping the species into genera, so the system 

 independently adopted here was based on the study of Australian forms only. 



Attention is drawn to the fact tliat various genera hitherto proposed were 

 founded uj^on venation characters, in accordance with the usual custom of 

 grouping the StratiomyiirJae, but such a treatment is not only impossible with the 

 species under discussion, as shown in this study, but also will have to be aban- 

 doned as a main factor in grrouping other species of Stratiovu/iidae before a 

 natural classification of the family can be attained . 



It is scarcely to be expected that any alteration will l)e made upon the prin- 

 ciples underlying the present scheme of treating the genera under the tribe Chiro- 

 myzini, but it is possible that the genus Chiromyza is divisible into two groups, 

 formed according to whether the eyes of the male are contiguous or separated, but 

 this development, for obvious reasons, cannot be undertaken in this paper.
