Neuration : SC- and R' of hindwing on a very short stalk ; D'- almost four 

 times as long as D^, very oblique, sliglitly angiilate ; D'' a little shorter than D^ ; 

 lower angle of cell acnte. 



(Jenitalia : tenth tergite very different from that of the other sjiecies of 

 Pohjptychm in being completely divided into two very slender, pointed processes, 

 whicli stand widely separate; tenth sternite broken, apparently broad, rounded-

Libyoclanis gen. nov.

 nearly equal in length, the joint between them not open. Antenna cylindrical. 

 Tibiae spinose at apex ; si)nrs much shorter than in allied genera mentioned ; two 

 jiairs to hindtibia, the short spur a little shorter than tlie tibia is broad, half the 

 length of the long one ; cell of hindwing trnncate, both the upper and lower angles 

 being about 90' ; SC- and R' on a short stalk. 



Antevaginal ridge asymmetrical, produced into a process on each side, the 

 processes being unequal in size. 



Type : L. bainbridgei gen. nov.
