Maskeliya and Madulosima, Ceylon (Pole, Green); in December and 
March, two specimens. 
Chelaria, Haw. 
Labial palpi with second joint clothed beneath with single or double 
tuft of scales, rarely with scales appressed beneath but rough above, 
terminal joint longer than second, thickened with scales usually forming 
a_more or less distinct projection posteriorly, acute. Forewings often 
with tufts of scales, 2 and 3 remote, 6 to apex or termen, 7 and 8 stalked, 
or 7 and 8 out of 6, or rarely 7 absent. Hindwings elongate-trapezoidal, | 
termen beneath apex more or less bisinuate, oblique; 3-5 more or less. 
approximated at base, 6 and 7 stalked. 
T have extended the essential characters of this genus as above ; from 
a careful study of considerable material I am convinced it is justifiable. 
It is exceptional to find the origination of veins 7 and 8 of forewings 
out of 6 an insuflicient character for generic distinction from forms 
with 6 separate (though the origination of 6 from the stalk of 7 
and 8 is seldom if ever of generic value), but in this instance the 
transition is practically complete, vein 6 in certain forms being very 
closely approximated to 7; the reason seems to be due to the frequently 
apical termination of 6 (an unusual structure). By this extension of 
characters the Australian and African genera Allocota, Deuteroptila, Semo- 
dictis, and Cymatomorpha become synonyms of Chelaria, ‘The species are 
often very similar in general appearance, and the structural distinctions 
must therefore be carefully noticed; a tabulation into groups. based on 
these is given below, which may assist determination. Besides the 
seventeen species described here there is another, indica, Wals., which E 
have not yet been able to identify. 
Tuft double, 7 and 8 out of 6 — anguinea. 
Tuft double, 6 separate, 7 and 3 stalked—soptila, ericta, corynetis, 
tophana, lactifera. 
Tuft single, 7 absent—scriniata. 
No tuft, 6 separate, 7 and 8 stalked—tonsa. 
Tuft single, 7 and 8 out of 6—caryodora, silvestris. 
Tuft single, 6 separate, 7 and 8 stalked—scopulosa, spathota, vertieosa, 
phacelota, tortuosa, paroctas, particulata, 
Chelaria anguinea, n. sp. 
g. 16mm. Head and thorax whitish, irrorated with grey and fuscous. 
Palpi whitish irrorated with grey and dark fuscous, second joint with two 
moderate rounded tufts beneath tinged with ochreous, terminal joint 
with median band of dark fuscous suffusion and strong median projection 
of scales posteriorly. Abdomen whitish irrorated with grey and dark grey. 
Forewings elongate, very narrow, costa gently arched, with scales rather 
prominent at 2, apex round-pointed, termen extremely obliquely rounded; 
7 and 8 out of 6; scattered tufts of scales, and a large tuft on fold at ¢ 
of wing ; light brownish irrorated with white, and irregularly sprinkled 
with dark fuscous; a short black dash beneath costa near base; a narrow 
dark fuscous patch extending along costa from % to 3, cut by two oblique 
white strigule ; some indications of irregularly scattered small undefined 
dark fuscous marks; two or three black dashes towards apex: cilia grey 
irrorated with whitish. Hindwings pale grey, paler and thinly scaled 
anteriorly ; cilia whitish-ochreous. 
Khasis ; in May, one specimen. 
Chelaria lactifera, n. sp. 
3.14mm. Head and thorax ochreous-whitish, patagia brown. Palpi 
whitish, second joint with long rough projecting basal and apical tufts
