PAPILIONID.Ti;. PIERIN.'E. — PINACOPTERYX. 



Miilr. Upperside glaucous wliite, dusted with grey at the base. Anterior 

 wings with the costa and hind margin edged with a narrow black line ; costa 

 irrorated below this with grey ; apical region and hind margin to below the 

 lowest discoeelhdar nerviile ashy, the colour running inwards along the nervures 

 to two large l)ut ill-defined ashy spots, one confluent with the dark markings on 

 the costa, and another extending over and beyond the two upper median nervules, 

 and connected liy a series of dusky atoms with an indistinct spot l)elow the last 

 median nervule ; a conspicuous black spot on the second discocellular nervule, 

 and the extremity of the submedian nervure is also slightly marked with black. 

 Posterior wings white, with the region of the anal angle slightly shaded with 

 yellow ; fringes with traces of a dusky line towards the anal angle. 



Both sexes show considerable resemblance to the female of /'. L'diaua, 

 from which they may at once be distinguished by the absence of the row of spots 

 on the disk of the posterior wings. The male has considerable resemblance 

 to that of P. Mahoho, but is larger, with the hind margin of the anterior wings 

 slightly but distinctly emarginate, and the extremity of the submedian nervure 

 on the same wings is marked with Idack. 



UNDERSir>E nearly as in B. Maliaho, but ratlier more brightly coloured. 



Female. Upperside yellowish white. Anterior wings nearly as in the 

 male, but with the dark spots and markings more clearly defined, larger, and 

 rather more extended, the border reaching the hinder angle ; there is a well- 

 marked oblong spot between the lowest median nervule and the submedian 

 nervure. Posterior wings with rather large blackish spots at the extremities of 

 all the )narginal nervures. 



Underside. Anterior wings white, slightly greenish towards the base, 

 and shading into buff towards the costa, apex and hind margin. Three con- 

 spicuous black spots, of nearly equal size ; one discocellular, one between the 

 two upper median nervules, and the third above the submedian nervure. 

 Posterior wings Iniff, with the base of the costa marked with saffron.
