 I lin. 



$ White, with white -spotted black hind-onairjiiis. Fore-unng : costa 

 with a linear black edging ; a black border on hind-margin, broad at 

 apex, and narrowing to a point at anal angle, — its inner edge irregu- 

 larly dentate and excavate ; a row of elongate white spots, from four 

 to seven, in this border, lessening in size towards posterior angle, but 

 not extending below first median nervule ; a small sublinear black 

 spot at extremity of discoidal cell. Hind-ioing : a black border of 

 moderate width on hind-margin, enclosing four rather large white 

 spots, — of which rarely all are indistinct except the first; in some 

 specimens an irregular black transverse mark on costa before apex ; 

 very rarely a thin blackish line at extremity of discoidal cell. Under 

 SIDE. — Main markings like those of upper side, hut hind-mwgi7ial borders 

 not so black, tinged with broiun ; hind-wing and marginal spots in fore- 

 luing lemon-yellow or greyish-yellow., — the former with neuration almost 

 always more or less clouded with black. Fore-wing : base with a faint 

 yellow tinge ; rarely a projection from costal black edging towards 

 terminal disco-cellular spot ; hind-marginal spots larger and more 

 sharply defined. Hind-vjlng : costa near base edged with chrome- 

 yellow ; pre-apical costal black mark conspicuous ; a similar but dif- 

 fused transverse black mark from about origin of second median 

 nervule to about middle of submedian nervure, crossed by a longi- 

 tudinal black streak from near base of median nervure to near anal 

 angle ; hind-marginal border containing five spots of the ground-colour, 

 the additional spot being close to anal angle ; near base, a short longi- 

 tudinal chrome-yellow streak between median and submedian nervures, 

 and another close to inner margin. Cilia black, interrupted with 

 white between nervules. 



$ Varying from- very pale whitish-yelloiv to pale ochrcous-yclloiv ; 

 hind-marginal black borders very broad. Fore-iuing : only two or three 



^ This reference was confirmed by a figure in the rough drawings of some of Wallengren's 

 type specimens shown to me by Mr. W. F. Kii'by, which, under the name of ^' Pinacopteryx
