PAPILIO. 17 



margin as in cerberus, but there is always a large yellow spot at 

 base of interspace 7 ; interspace 1 black, with a pale patch in the 

 middle ; the black terminal border broader, the inwardly extended 

 cone-shaped markings prominent, those in interspaces 2 and 3 with 

 piie buff lateral edgings, extended inwards to the postdiscal spots. 

 In both c? and the hind wing on the upperside is clothed with 

 soft, silky, long brownish-black hairs from base along the dorsal 

 area. 



Exp. cJ $ 140-180 mm. (S-53-7'15"). 



Hob. Southern India : Bombay to Travancore. 



Larva. Boughly cylindrical, tapers a little to each end, with two 

 rows of fleshy processes somewhat curved forwards and a double 

 row on each side that are much shorter. On the 2nd, 3rd and 

 4th segments an additional long pair between the dorsal and lateral 

 rows. Head smooth and black ; body of a uniform dark madder- 

 brown, prettily lighted with a tinge of pink at the points of some 

 of the fleshy processes ; dorsal process on the 8th segment and a 

 lateral pair on the 7th pinkish- white, with a band of the same 

 colour uniting them. 



Pupa. Suspended by the tail and a band that encircles it much 

 nearer the head than is usual with Papilio pupa?. In form stout, 

 flattened, dilated in the middle, with head and thorax thrown back. 

 Head somewhat angular and tuberculated ; two of the abdominal 

 segments each with a prominent dorsal pair of pointed tubercles. 

 Colour usually light brown, with a strongly contrasting saddle of 

 old gold. (After Davidson $ AitJcen.} Mr. T. A. Sealy (Proc. Ent. 

 Soc. 1875, p. ix) states : " The pupa possesses the power of 

 making a curious noise like ' pha-pha' !, and makes it very loudly 

 when touched ; the noise is accompanied (perhaps produced) by a 

 .short contraction of the abdominal segments. I thought at first 

 it was merely produced by the rubbing of one ring of the pupa- 

 case against the next, but the sound did not resemble a mere 

 fractional sound, it was more like the sound of a rush of air 

 through small holes ' pha-pha.' I tried to produce it with a 

 dead chrysalis but failed : the pupa sometimes contracted on being 

 touched without making the noise, and appeared unable to make 

 the noise until some time was given to allow it to recover its 

 vigour." Messrs. Davidson and Aitken have also noticed this power 

 in the pupa, but they speak of it " as a husky squeaking noise, 

 produced apparently by friction of the abdominal rings."
