CAMPYLOMYZARIAE 

 Members of this group are easily distinguished from the Lestre- 

 miinariae by the simple character of the fourth vein [pi. 33, fig. 

 4' 5' 7]- ^^ recognize at present the two genera Joanissia and 

 Campylomyza, though the latter comprises a number of divergent 

 forms which should probably be referred to different genera.
