52 LIFE-HISTORIES OF EUCOSMIDAS 
Larva about 8 mm. long, cylindrical, tapering very slightly posteriorly ; 
head flattened, yellow ; prothoracic shield large, yellow ; body soft, uniformly 
greyish-yellow, segments moderately distinct, with longish white hairs arising 
from shiny chitinized plates concolorous with body ; prolegs equally developed, 
Pupa about 5 mm. long, cylindrical, tapering posteriorly, anal segment 
with yellowish cremastral hooks ; abdominal segments anteriorly with a 
transverse row of small spinous processes across dorsal area. (Pusa Insectary 
Cage-slips 880, 910.) 
EUCOSMA MELANONEURA, MEYR. ee 
Eucosma melanoneura, Meyr., B. J., XXI, 866 (1912)('). 
Only known from the Khasi Hills('). 
The larvee of this species are abundant at Shillong in September, spinning 
up the flowers of Rhus semialata into little knots and feeding on the flowers 
under cover of a silken tube covered with fragments of the flowers. The 
attacked flower-heads are quite conspicuous and in many cases practically 
every flower is destroyed. Pupation takes place within the larval galleries, 
the moths emerging towards the end of September and in October.

This species is widely distributed around the Mediterranean Region(": * *), 
St. Helena(2), West Indies(?), Central and South America(?), Australia(?) 
and Hawaii(2), and has also been recorded from Pundaluoya in Ceylon(?) 
and is doubtless of common occurrence throughout India. 
Larva on Althea, Lavatera, Malva and allies(*). 
Willcocks(*) gives the following description of the early stages :— 
‘“‘ Egg. The eggs are laid singly on the seed capsules or fruits and flower- 
buds of the ornamental! hollyhock (Althea sp.) ...... ihe eo Facer ce is 
Me eae 0°6 mm. long by 0°36 mm. wide ; it is oval in form, convex, and the 
shell is very rugose in appearance. The colour is pale at first and then a 
horse-shoe-shaped irregular line of scarlet becomes visible and this may gradu- 
ally spread until the whole egg becomes red or orange-red in colour. Before 
hatching the egg again becomes pale with dark spot at one end formed by the 
head of the young larva and a pinkish or reddish line along one side.
