verse cubitus interstitial with the transverse radius or joining the 



radius a little beyond it Cephaleia, Panzer. 



Basal nervure uniting with the subcostal vein in the angle formed by 

 the cubitus ; second transverse cubitus uniting with the radius 

 before the transverse radius Ccenolyda, Konow. 



3. Intercostal vein forked at apex, the outer branch attaining the costal 



vein, the inner branch joining the subcostal vein and thus forming 



two closed basal cells 4. 



Intercostal vein with only the outer branch of the fork, therefore only
