Sjjmpliaeâ/ra perdix Butl. Î. 



Extremely close to S. dirtea S, but seems to difler by some 

 constant though slight peculiarities. The whitish subapical spot on 

 the anterior wing is always absent; the spots in and around cell 

 are darker and less distinct, whilst the two spots placed one on 

 each side of the upper discoidal nervule are generally emitting to- 

 wards the apex streaks of sprinkled golden bronzy atoms; the 

 innermargin of the bluish marginal fascia is less dentate and not 

 quite so broad at external angle. 



Below the wings are more concolorous, the pale spots being 

 almost of the same tint as the ground-colour and therefore very 

 obsolete , except in the cells where they are black-contoured , more- 

 over the anterior wings have the following clear blue markings: 

 viz , on the disk a narrow stripe between S^'^l and 2ii<i and a 

 wedge-shaped spot between 2^*1 and 1st median nervule; a sub- 

 marginal blotch between l^t median nervule and submedian ner- 

 vure and a small point near apex; the posterior wings with a 

 distinct row of strigiform blackish submarginal spots. 



The discovery of the male sex of S. perdix shows that Honraths 

 suggestion ^), S. perdix should be a varietal form of S. Pardalina 

 Staud. , is quite erroneous.
