50 MR. A. R. WALLACE ON THE PAPILIONID.E 



scales in the cell ; apical portion of the wing more thickly powdered between the nervures, 

 the powdering fading away towards the outer angle. Posterior wings with a kyt-ge yel- 

 lowish-Avhite patch, commencing close to the anterior margin, ■nddening in the middle so 

 as to cross the end of the cell, and ending in a triangle with prolonged apex at the abdo- 

 minal margin ; the outer edge of this spot is regularly angulated and scalloped ; two very 

 faint brown lunules occur next the anal angle ; and the outer margin is rather broadly 

 white-edged between the dentations. 



Vncler side : the anterior wings have distinct grevish lines of scales between the ner- 

 vures in the apical region ; posterior wings not dotted Avith scales as in P. Secerns, but 

 with two or thi-ee single rows of scales in the ccU only; the yellowish band consisting of 

 a lunule next the upper margui, followed by three rhomboidal spots notched below, of 

 which the middle one is the largest, then a roundish spot and a small horizontal mark ; 

 a row of seven submarginal lunules, of which the three middle ones are smallest and 

 nearly obsolete, and that at the anal angle much the largest and, with the whitish mar- 

 ginal spot below it, forming an incomplete ocellus. 



Expanse of wings 3i-3f inches.

Local form a. Has more falcate wings and longer tail ; the red marks at the anal 

 angle beneath are divided by a \dolet-white mark. 

 Hab. North India. 



Local form b. Same form of wings as the last, but smaller ; the third and fourth 

 lunules from the anal angle beneath very small or quite absent. 

 Hab. Java, Sumatra [Wall.). 



57. Papilio Hecuba, n. s. Tab. V. fig. 3 (d). 



Upper wings falcate, and then* outer margin much hollowed out, as in, many of the 

 Celebes butterflies. 



6 . Tipper side : the outer half of the anterior wings of a fine cottony texture, as in 

 P. Helenus, but more marked ; the red lunule at the anal angle wanting ; the rest as in 

 P. Helenus. 



Under side : the lunules and ocelli are ochre-yellow instead of deep red, the two outer 

 ones very small, the third almost obsolete, and the next two absent ; the anal oceUus is 

 bordered with blue above, and adjoining it is a blue lunule in the place of the red one in 

 P. Helemis.
