has been pointed out by several writers. De Meijere was 

 the first to remove the genus from the Eriopterini to the 

 Limnophilini, to where it runs by means of the existing 

 keys, but it seems very possible that a new tribe may be 

 required for it when the immature stages are made known. 

 The chief venational peculiarities of Lechria are the 

 apparent fusion of ^2 with By near the tip of the latter, a 

 condition that is quite comparable with that found in the 

 tribe Pediciini as discussed by the writer in another paper, 

 (Entomological News, vol. 29, pp. 201-205, pi. 12; 1918), 

 and the union of r-m dii*ectly with the sector before its fork. 

 Some features of structure are suggestive of Dicranoptycha, 

 and more evidence may show these two genera to be closer 

 than their present arrangement would indicate.
