observed to make three cones before wandering to pupate in the 
tightly rolled-over edge of leaf.” I think it probable that the 
species of the scarlet and yellow group of this genus all feed on 
Myrtacece. 
Gracilaria tetratypa Meyr. 
According to information received from Mr. T. B. Fletcher, it 
appears that the foodplant ascribed to 0. cirrhocrotala Meyr. was 
erroneously identified through a confused use of Indian vernacular 
names, and that the species was actually reared from the same tree 
(, Sapium ) as tetratypa ; that the differences in the imago are 
individual, not specific; and that therefore cirrhocrotala must be 
merged in tetratypa. 
Gracilaria rhaptocrossa, n. sp. 
J . 8 mm. Head, thorax whitish-ochreous. Fore wings rather 
narrow, moderately pointed ; pale reddish-ochreous, speckled grey 
except on dorsal area, dorsal edge suffused whitish : cilia whitish- 
ochreous, round apex three dark grey lines on outer half. Hind- 
wings dark grey ; cilia grey.

EPERMENIADZE. 
LASIOSTEGA, n. g. 
Head rough-scaled on crown, with tuft of long rough scales 
projecting over forehead, face smooth; ocelli posterior; tongue 
slender, developed. Antennae serrulate, moderately and 
evenly ciliated (1), scape moderate, with short close pecten. Labial 
palpi moderate, curved, subascending, second joint somewhat 
thickened with appressed scales, slightly rough at apex beneath, 
terminal joint about half second, cylindrical, obtuse. Maxillary 
palpi obsolete. Fore tibiae very short, tarsi nearly 4 times as long; 
hind tibiae and basal joint of tarsi with roughly projecting bristles 
above, other tarsal joints with short apical bristles, upper spurs of 
tibiae at |. Forewings (apparently) 2-4 very short, 5 absent, 
7 absent, 8 from middle, a few fine scattered slender scales in 
dorsal cilia. Hindwings linear-lanceolate, cilia 6; (apparently) 
2-4 very short, 5-7 approximated basally, 6 to termen. 
Apparently (especially by reason of palpi and hind legs) a curious 
specialised form of this family. 
Lasiostega siderina, n. sp. 
6 $ . 7-8 mm. Head, thorax glossy leaden-grey. Palpi dark 
grey. Antennae grey. Forewings narrow, parallel-sided, short- 
pointed ; glossy grey, with faint lilac tinge, bases of scales with 
pale reflections : cilia light grey, scattered scales darker, round 
apex scattered pale points. Hindwings grey ; cilia light grey.
