 One spécimen, maie, in the South African Muséum, Cape Town. 

 I take the libertv to name the species after the Director of the 

 Muséum, Dr L. Péringuey. 



It is a fine looking and verv distinct species, \vhicli at first sight 

 has some likeness to B. nebulosus Klug; but the subtriangular 

 pterostigma, the stronglv rounded tips of the -wings, the absence 

 of dark shadow along the cross veins and the other characters 

 mentioned in the table make it easelv recoa;nizable.
