ERIGORGUS, Forster.

This is one of the most easily recognised genera of the present group, 

 on account of the submarginal nervure being emitted irom the cubital at 

 the same or almost the same point as the second recurrent, and the two 

 thus forming a continuous line through the cubital. In all other respects 

 it is hardly to be distinguished from Anomalon. Forster further divided 

 it iiitt) Barylypa, whose species differed from typical Erigorgus in having 

 the parallel (or anal) nervure emitted above the centre of the brachial 

 cell, and these were further subdivided into species with {Laphycles) or 

 without the clypeus centrally a little produced ; Schmiedeknecht has sunk 

 the former genus and I do not consider so slight a distinction as the 

 position of an anal nervure constitutes generic rank, tliough that of the 

 submarginal may be placed upon a different footing, since it exhibits dis- 

 tinct transition to the Ophionides and shows the present group allied 

 therewith.
