 R; R2+3 less than one-half R2, in alignment with the basai section 

 of R2; r on i?2 about one and one-half its length beyond the fork and 

 on Ri about two and one-half times its length from the tip ; cell M\ 

 lacking; in the maie the veins issuing from cell ist M-> tend strongly 

 to atrophy; m three to four times the outer deflection of M3, cell 

 znd M-2 being very wide; in the female the veins are stronger and more 

 nearly equidistant; basai deflection of Cu\ about one-third its length
