Some venational characters of the $ and 9 of franklini and the 5 $ 

 and 2? of macrotona have been noted. The subtriangle in hind wing 

 is present in all. In both species M4 and Cm in front wing are strongly 

 convergent, never more than 2 rows of cells between these veins beyond 

 the first row of post trigonal cells, excepting occasionally at the extreme 

 wing margin where there may be from i to 3 small cells. This character 

 is valuable in defining groups within this genus. There is considerable 

 variation in the distal end of the anal loop, due to the weakness of the 

 enclosing veins, and the width at the extreme apex may vary from 2 to 4 

 cells. Other venational characters may be tabulated for clearness. 

 These characters are given without any implication that specific vena- 

 tional differences exist between the two species. In the two the size 

 of the wings is nearly the same, franklini being possibly I shorter. 

 Macrotona has the longest abdomen, relative to alar expanse, of any 

 species of Somatochlora.
