PLATE LXXII, 
DESCRIPTIONS OF TWO NEW ASSAMESE SPECIES OF PAPILIO, RECEIVED 
FROM MAJOR JENKINS. 
Tue two interesting additions to the genus Papilio represented 
in the annexed Plate, form part of a collection of insects with which 
I have been favoured by Major Jenkins, and to whom I beg leave 
to present the best thanks} both of my subscribers and myself, 
feeling convinced that they will consider that every addition made 
to our knowledge of the beautiful productions of our distant territo- 
ries by the zeal of gentlemen resident in such districts, is a subject 
of congratulation.

This species is very nearly allied to P. Helenus *, but differs not 
only in the form of the pale patch on the dise of the hind wings, 
but also in the markings of the underside of the same wings. The 
upper surface of the wings is entirely black, a slightly brown 
appearance being produced by a few luteous seales arranged in 
rows in the discoidal cell, and beyond the middle of the fore 
wings. The hind ones have a large cream-white patch on the dise 
towards the outer angle, formed of four confluent spots (the outer 
one generally hidden by the hind margin of the fore wings); the 
one nearest the body being oval, the next oblong with the extremity 
obliquely emarginate, as it is also in the third spot, which is much 
smaller than the second, and the fourth is still smaller. The fore 
wings on the under side have a brown appearance, produced by a 
greater quantity of the luteous scales ; the incisures are slightly 
marked with white; the hind wings on this side are similarly 
marked with four white spots as above, but in addition to these, 
there extend three pale luteous lunules towards the anal margin ; 
and there is also a narrow row of the same coloured lunules parallel 
with the white incisions, which are here more distinct than above. 
® Tt is accordingly named after his unfortunate brother, Chaon.
