BY S. A. NEAVE, M.A., B.Sc, F.E.S. 



The following striliiug new Nymplialine butterfly occurs among my 

 collection of Lepidoptera made during a recent tour in Nyasaland: — 



Pseudacrasa deludens, sp. nov. 



Primaries. — Upper side dusky with the following white spots : one beneath 

 the costa near the distal end of the cell ; one immediately beyond the cell end 

 in area 4 ; a row of 3 spots forming part of a broken siibapical bar midway 

 between end of cell and apex ; of these the second from the costa is more 

 distally placed than the others, the third being the largest. A small discal 

 spot occurs in area 3, and immediately below it in area 2 is a large spot, the 

 largest in the wing. A svibmarginal row of 8 small spots from apex to hind 

 margin, that in area 4 being somewhat fiirther from the margin than the 

 remainder. 



Secondaries. — Ujyperside : a small dusky triangular area at the base ; a broad 

 marginal band of the same dusky colour ; the intervening discal area pale 

 ochreous, extending from the inner margin to the costa, but not to the actual 

 costal margin which is dusky. A marginal row of white spots, one at least in 

 each area (two above costa) becoming smaller toward the anal angle. 



Underside as above, with a few additional spots. In the Primaries, a small 

 spot in area lb immediately below the large spot in area 2. In the Secondaries 

 some small additional internervular, submarginal, somewhat evanescent spots. 

 Also in each wing a small white spot at the base above tlie costa (in the 

 Secondaries before the precostal). I'alpi black, with an external lateral white
