Taranga. 



Under this name Mr. W. F. Kirby ( Trans. Entom. Soc. 

 1883, p. 201, fig. ) describes a genus Taranga " apparently 

 allied to Pemphredon " but which is really related to Pison. 

 Kohl {Ann. K. K, Natter. Hofmns. Wzen, XI. p. 458) 

 regards it as a division of Pison. Bingham {Fauna of 

 India^ Hym. i. p. 218) says that he has "taken specimens of 

 Pzsojz with three cubital cells in one fore wing, only two 

 in the other. Such seems to be the case with the allied 

 genus Taranga Kirby. Kohl unites Taranga to Pison ; 

 but from a careful examination of the type, I have come 

 to the conclusion that they are distinct." I have noticed 

 myself that the outer nervure of the pendicular cellule 

 tends to become obliterated in species where it is normally 

 present. The neu ration in Taranga appears to be normal, 

 and not merely an individual aberration ; but still I cannot 

 regard it in any other light than as a division of Pison. 

 Otherwise the species with neuration differing from the 

 type, e.g.^ Pisonites, would also have to be treated as distinct 

 genera.
