22 (21). Stigma covering four to se\en cells. Supplementar\- sectors not attached. 

 S[jines on legs medium in length. Genera of South America 23 



23 (24). Basal space often crossed. Sectors between Mia and M. do not arise before 

 the level of the inner end of the stigma. Mi-^ forks alxjut two cells beyond the 

 subnodus. Quadrangle with one cross-\ein. Brazil. (Fig. 30. ) 



Heliocharis Selys. 1853 



24 (23). Basal space free. M2 arises within a cell of the subnodus. Quadrangle 

 with one or two cross-veins 25 



25 (26). Some sectors between Mia and Mj arise far before the level of the stigma. 

 Quadrangle with one cross-\ein. Brazil. (Fig. 32.). . . .Dicterias Selys, 1S53 



26 (25). Xo sectors between Mi^and M.arise before the level of the stigma. Quad- 

 rangle with two cross- veins. British Guiana. (Fig. 31.) 



Neocharis Foerster. 1906 



27 (18). Antenodal cross-veins usually less than nine. Area posterior to Cu* of 

 more than one row of cells, but Cuj not s\mmetrically forked 28 



28 (29). Two cross-veins in the quadrangle; two or three often in the subquad- 

 rangle. Stigma about three times as long as wide. Fourth antenodal over the 

 arculus. M2 arising four to five cells beyond the subnodus. Straits Settle- 

 ments. (Fig. 33.) Devadatta Kirby, 1890 



(Tetraneura Selys, 1859) 



29 (28). Xo cross-veins in the quadrangle: usually none in the subquadrangle. 

 Stigma about five times as long as wide, fusiform in outline. Second or third 

 antenodal over the arculus • ■ .30 



30 (33). Genera of the Old World. M2*not arising more than one cell beyond the 

 subnodus. Sectors present between Mi and M^. Second antenodal over the 

 arculus 31 



31 (32). M2 arising at the subnodus. or within one-half cell of it: M^ arising three 

 to five cells beyond M2. Arculus less than one-half way from the base of the 

 wing to the nodus. Antenodals fi\'e to seven. Australia and Malaysia. (Fig. 

 34.) Diphlebia Selys, 1869 



32 (31). M2 arising one cell beyond the subnodus. Mi^ five cells beyond Mj. 

 Arculus at one-half the distance from the base of the wing to the nodus. An- 

 tenodals generally five. West Africa Pentaphlebia" Foerster, 1909 



33 (30). A genus of the Xew World. .M; arising two to four cells beyond the sub- 

 nodus. Often no sectors between Mi and M^. The third antenodal over the 

 arculus. Colombia. (Fig. 35.) Amphipteryx Selys. 1853 



34 (17)- Quadrangle about twice as long as wide. Wings widest before the level of 

 the nodus. Antenodals about fifteen. India to China. (Fig. 36.)
