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 à large yel. 
lowish-white patch, commeneing close to the anterior margin, widening in the middle so 
as to eross 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 oceur next the anal angle; and the outer margin is rather broadly 
white-edged between the dentations. 
Under side: the anterior wings have distinct greyish lines of scales between the ner- 
vures in the apical region; posterior wings not dotted with scales as in P. Severus, but 
with two or three single rows of scales in the cell only; the yellowish band consisting of 
& lunule next the upper margin, 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 33-32 inches.

Local form a. Has more falcate wings and longer tail; the red marks at the anal | 
angle beneath are divided by a violet-white mark. 
Hab. North India. 
Local form 4. Same form of wings as the last, but smaller; the third and fourth — 
lunules from the anal angle beneath very small or quite absent. s.

57. PAPILIO Hecusa, n. s. Tab. V. fig. 3(¢). 
Upper wings faleate, and their outer margin much hollowed out, as in many of the | 
Celebes butterflies. 
4. Upper 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 a8 — 
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 ocellus 5 
bordered with blue above, and adjoining it is a blue lunule in the place of the red one - 
P. Helenus.
