PIERID^E. 31 



coidal cell ; some dark-grey, ill-defined spots near base, 

 arranged transversely ; beyond middle, parallel to hind- 

 margin, a band of about seven darker spots, commencing on 

 costa with a rather conspicuous, larger mark ; hind-marginal 

 dots larger than those in fore-wing. The grey irrorations of 

 the under-side are often very thinly sprinkled, and are fre- 

 quently altogether wanting in the central portion of hind-wing. 

 ? . Rather more yellowish than $ , but with the same 

 pearly lustre. Fore-wing : a more or less distinct disco- 

 cellular dot ; beyond middle a row of brownish spots parallel 

 to hind-margin, consisting of three small spots forming a 

 streak from costa, and a rounded, larger spot between first 

 and second median nervules ; occasionally a fifth indistinct 

 spot between third median nervule and inner-margin ; spots 

 on hind-margin very much larger than in $ , contiguous, 

 somewhat rhomboidal in form (in some instances almost 

 forming a marginal stripe), the last spot on submedian nervure. 

 Hind-wing : dots on hind-margin larger than in $ , but not 

 one-fourth the size of those in fore-wing ; occasionally a row 

 of spots beyond middle, similar to that on under-side of $ , 

 but not so distinct. UNDER-SIDE. Similar to $ . Fore- 

 wing : the spots beyond middle faintly marked ; hind-mar- 

 ginal dots barely larger than in $ ; base tinged with very 

 pale greenish-yellow. 



Woods and copses. Not unfrequenfc in gardens.

Abundant where it occurs. At the Knysna this pretty little Pieris was 

 the first of the Genus that I captured. It is a brisk flier, and may com- 

 monly be seen in the open spots of the woods congregated around a 

 flowering bush. The brood of this Butterfly that appears later in the 

 season consists of larger specimens than those perfected in the spring and 

 early summer ; it is also those of the late brood that are so little irrorated 

 on the under-surface of the wings.
