PLATE LXXX. 
ILLUSTRATIONS OF TWO ADDITIONAL SPECIES OF PAPILIO, SENT 
FROM ASSAM BY MAJOR JENKINS. 
Since the publication of the 19th number of this work, in 
which two new species of Papilio, kindly communicated from Assam 
by Major F. Jenkins, were figured, I have received two cases of 
insects from the same gentleman, in which were contained speci- 
mens of the two species represented, for the first time, in the 
accompanying plate. They had previously, however, been described 
by myself in the Annals of Natural History, from specimens 
received from Sylhet by the Rev. J. Stainforth, now in the col- 
lection of H. Doubleday, Esq. In respect, therefore, to their 
geographical range, this circumstance becomes of importance. It 
is also rather remarkable, that all these new Assamese species 
should be so little striking in their colours.

aree discoidalis, serie submarginali et marginali punctorum ad apicem extensis, albidis

The under side of a fine light coloured specimen is here repre- 
sented, the upper side differing in having the cream-white colour 
rather less diffused, especially towards the inner angle of the fore 
wings ; sometimes, also, the marginal spots of the fore wings are 
entirely, and the submarginal ones nearly, obliterated towards the 
tip of the wings, except the large one next the tip; the large 
discoidal spots near the inner angle of the fore wings on the upper 
side are more or less obsolete, and occasionally confluent with the 
adjacent submarginal patches. 
PAPILIO CASTOR. Westw. 
(Plate 80, fig. 2 and 2*.) 
P. alis latis anticis apice subacutis, posticis sinuatis ecaudatis, omnibus supra fuscis, anticis 
venis strigisque intermediis nigris, margine punctis minutis albis; posticis macula magna 
discoidali (versus angulum externum extensa) alba in 4 vel 5 partes irregulares venis 
divisa ; sinubus albo marginatis, anticis subtus macula parva ad apicem are: discoidalis,
