ther from the angle of the brachial areolet, but in the others form 

 a petiolated fork, the anterior branch being very short, and nearly 

 transverse, in Vlatyura, Ashuhdnm, and Ceroplatus. 



"In the second group most of the genera have the petiolate 

 forked vein, which represents the subapical vein, and a second 

 forked vein, the pobrachial with the subanal (the latter wanting 

 in Mycetojjhila nitida and its affinities). Scio2)Jula and Tetrago- 

 nenra have a small areolet, closed by a transverse vein (wanting 

 in the rest), which, though changed in position, appears analogous 

 to the anterior branch of the cubital in Flatyura, etc. Lestremia 

 and the allied genera differ from Seiara chiefly by the origin of 

 the subapical vein ; the spurless tibiae, shorter coxa3, and vacillat- 

 ing number of the joints of the antennae, and evidently four-jointed 

 palpi, approaching, as I think, to Campylomyza, in which the 

 short coxae of the fore pair do not touch the second pair, the 

 subapical vein is simple, and the subanal springs from the pobra- 

 chial, very near the end, forming a short fork. Catocha is allied 

 to Lestremia, but the difference of the veins is evident. "VYith 

 respect to Epidajms, the disappearance of the ocelli, with the 

 wings and halteres, leaves fewer marks by which to collocate it, 

 but the form of the abdomen, with the sixteen- jointed antennae, 

 place it near Seiara j the spurless tibiae show an approach to 

 Lestremia.
