XII. Description of the Larva and Pupa of Papilio 
homerus, Fab. By Cuarues B. Taytor, F.E.S. 
[Read February 28th, 1894.] 
Axsout two or three years ago, a lady residing in the Bath 
district of the Parish of Saint Thomas, and a diligent 
collector of insects, discovered seven examples of a large 
Caterpillar of a beautiful green colour, on a tree bearing 
large subovate glossy green leaves (botanical name un- 
known) growing near a certain locality known as the 
“Fountain Road.” Of these she was good ‘enough to 
send me four specimens, which unfortunately, however, 
never reached my hands, as they were lost in transit, 
while I shortly afterwards heard that the other three 
examples had died before assuming the pupal state, as a 
result of confinement and want of proper attention. 
Towards the middle of last year Mrs. Swainson found 
another of these Caterpillars, which she sent down to the 
Museum of the Jamaica Institute for identification. It 
arrived at a time when there was no experienced 
Entomologist in charge (the post of Curator being then 
temporarily vacant), but on seeing it I ventured to express 
the belief that it was the larva of P. homerus. This 
individual also died during the process of casting the 
larval skin. Through the kindness of Lady Blake I was 
enabled to make a special expedition to Bath during 
November last, in search of this larva, and the day after 
my arrival (the 27th) had the good fortune to find an 
almost full-fed specimen, which developed a male 
homerus on the 29th of December following. It is 
worthy of note that all these Caterpillars were obtained 
from the same tree, notwithstanding that there were many 
others of the same species in the immediate neighbour- 
hood. 
Larva. Length about 2} inches, general appearance incrassated, 
the body being thickest from the 3rd to the 5th segments, from
