shortly described thus : ground colour, browu ; a series of imperfect 
outlines of lozenges, longer or shorter according to the length of the 
segments, in very dark brown ; the sub-dorsal lines, and some spots 
within the lozenges, of pale ochreous ; the fifth segment is distinguished 
by a long, dm-k doi-sal patch ; one or two of the larvas had a reddish 
tinge. 
Tlliaria : seeing that I was so unlucky with this species, I cannot 
give measurements with much certainty ; still I cannot think that any 
deficiency in growth would cause such great difference in the arrange- 
ment of the humps as appears between that given (after Treitschke) 
in the Manual, and the one that now follows, made from my own care- 
ful observation. Length 1| inches, figure slender ; on sixth segment a 
narrow transverse hump, formed of two lobes ; the seventh slightly 
swollen at the sides, and having on the belly a pair of warts, enclosing 
an inner pair much smaller ; on the ninth segment a small narrow 
hump ; on twelfth a very slight pair of warts ; the skin is glossy ; the 
ground colour in front is pale brown, brown on the intermediate seg- 
ments, and darker again behind ; the lozenge outlines darker brown, 
longer in form than in alniaria ; the sides covered with a delicate 
mottling of grey and pink ; the fifth segment has a long mark, paler 
than in alniaria. 
All the species draw together the leaves of their food to make a 
covering for the pupa, perhaps angularia and fuscantaria use the least 
amount of silk, whilst alniaria seems to make a strong, though open 
and irregular, web, to protect the openings between the leaves. 
The pupa of alniaria is of course the largest in the genus ; but in 
form it is much like angularia, being rather elongated, and tapering off 
to a flattened point at the tail, the wing cases short, the antennae 
well-defined ; colour pale brownish, with a slight tinge of green : the 
whole surface is granulated, except the segmental folds, which are 
glossy, and paler than the ground ; the wing cases are minutely freckled 
with brown, the abdomen blotched with brown. Erosaria and fus- 
cantaria are paler in colour than the other pupae, are not spotted, and 
the latter is of a stouter form than the rest. Tiliaria is distinguished 
by a little projection from the head-piece ; its colour is a pale brown 
with a reddish tinge, all (except the wing cases) freckled with darker 
brown ; the segmental folds glossy and paler. 
I will only add that the specimens of alniaria, which I bred, were 
very fine, and far exceeded the parent moth (which Mr. Lacy kindly 
allowed me to inspect) in richness of colour and beauty of their 
markings.
