Section 3. 



Anteniice of the male shorter than the thorax. Wings cinated, and 

 almost angular on the hind border; mediastinal vein ending rather 

 before two-thirds of the length of the wing, joined to the subcostal by 

 a veinlet very near its tip ; subcostal ending at about four-fifths of the 

 length ; radial and cubital springing from a common petiole, which they 

 rather exceed in length, and which proceeds from the subcostal at some 

 distance before half the length of the wing ; radial forked before one- 

 fourth of its length ; cubital joined near its base to tlie third externo- 

 medial by a veinlet, whose angle emits the first externo-medial ; the 

 latter is forked at half its length, and is connected with the third ex- 

 terno-medial by a veinlet whose angle emits the second externo-medial ; 

 third externo-medial connected wdth the subanal by tvvo veinlets, one 

 at a little before half the length of the wing, the other opposite the 

 middle of the discal areolet; axillary vein undulating; discal areolet 

 pentagonal, hardly twice longer than broad.

d d. Oue veinlet between the subanal and the third externo-medial. 

 e. Radial vein united to the subcostal at its fork. 



Mediastinal vein ending at a little before three-fourths of the length 

 of the wdng ; subcostal ending at a little beyond the mediastinal ; ra- 

 dial and cubital springing from a common petiole, w hich exceeds them 

 in length, and Avhich proceeds from the subcostal at much before half 

 the length of the wang ; radial forked before one-third of its length ; 

 its fore fork connected near the base by a transverse veinlet with the 

 subcostal ; cubital forming an angle near its base, and there connected 

 with the third externo-medial by an oblique transverse veinlet, whose 

 angle emits the first externo-medial ; the latter is forked beyond half its 

 length and is connected with the third externo-medial by a transverse 

 veinlet, whose angle emits the second externo-medial; subanal curved 

 abruptly to the hind border, coimected with the third externo-medial
