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

 medial ; the latter is forked at three-fourths of its length, and is con- 

 nected with the third externo-medial by a veinlet, whose angle emits 

 the second externo-medial ; subanal connected with the third externo- 

 medial by a veinlet, which is nearly opposite the middle of the penta- 

 gonal discal areolet.

SECTION 9. 



g g g y. Petiole of the first externo-medial vein about six times the length of its fork. 

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

 wing, connected by a transverse veinlet near its tip with the subcostal, 

 which ends at beyond three-fourths of the length ; radial and cubital 

 springing from a common petiole, which proceeds from the subcostal at 

 a little before half the length of the wing ; radial forked very near its 

 base ; first externo-medial springing from the cubital near the base of 

 the latter, forked towards its tip, connected by two transverse veinlet s 

 with the third externo-medial; second externo-medial springing from 

 the angle of the outer of the above veinlet, and rather nearer to the 

 inner than to the outer one there is another transverse veinlet, which 

 connects the third externo-medial with the subanal. Limnopldla p., Mcq.
