 Sc long, ending a short distance before the fork of Rs, Sc 2 

 at the tip of Sc x ; Rs slightly angulated at origin ; r at the 

 extreme tip of i? x and more than twice the length of this tip ; 

 basal deflection of R i+5 about two-fifths the length of Rs ; 

 cell 1st M 2 long and comparatively narrow, longer than any 

 of the veins issuing from it, its inner end arcuated, lying 

 proximad of r-m ; basal deflection of Cu x and short distance 

 beyond the fork of M.
