 close together, connected near base by a veinlet; cubitus straight, not curving 

 toward post-cubitus, the connecting veinlets each way of nearly equal length, a 

 veinlet connecting cubitus and first sector; three sectors, the third forked twice 

 before the outer series of gradate veinlets; five gradate veinlets of the inner
