182 Mr. E. D. Jones on two species of Molippa. 
Museum I found the wneus easily visible and agreeing 
with Fig. 2a. The other species I propose to name JM. 
smallima. The description of the new species may be left 
as that of JZ. sabina, Walker, Cat. Lep. Het. B. M. vi, p. 
1345 (1855), for though the specimens vary considerably 
from the type of Jf. sabina, they do not do so more than 
the individuals of sabina do among themselves. The 
genitalia must be consulted for identifying the species. 
It is interesting to find both species of larva feeding on 
the same food plant at the same season of the year. Both 
species are gregarious. 
The coloration of the larvee in relation to their habits is 
worthy of note. J. sabina is in the last stage of a dull grey 
or slightly drab colour with black markings, the spines 
being grey (Fig. 20), and this larva rests during the day- 
time near the ground on the trunk of the tree on which it 
feeds, a cluster of them having a wonderful resemblance to 
a patch of a mossy lichen that is very common in the 
woods about Castro. JL simzilima, on the other hand, rests 
during the day on the twigs amongst the leaves and 
flowers of the A/imosa, and the colour is yellow with black 
marblings, the spines being yellow (Fig. 10). This colora- 
tion combines so well with the surroundings that the 
caterpillar, though a brilliant object, is well concealed 
from its enemies.
