Thinopteryx neltulosa. (Plate CXIII. fig. 8.) 
Thinopteryx nebulosa, Butler, Jouni. Linn. Soc, Zool. vol. xvii. p. 203. d. 4 (1883). 
Near to T. delectans o£ Jajian, but larger; the markings, and especially the external 
borders, mottled with orange ; the yellow spots on the primaries forming a less distinct band 
and less central ; there are also two blackish lines across these wings as in T. crocopteratu, 
but less strongly defined, and the discocellulars are dark; the disk of the secondaries is 
always crossed by a more or less defined curved series of orange spots, and the border is 
interrupted by a blackish patch extending into the tail. Expanse of wings 69-71 millim. 
East India, Silhet. 
This species evidently represents T. delectans in India. It was regarded by Kollar as a 
variety of T. crocopterata; it is, however, more nearly allied to T. pndoraria. Although it 
is possible that all three may eventually be proved by breeding to be forms of one species, 
there is at present no reason for assuming that such is the case ; all are represented in both 
sexes, and can readily be distinguished, 
ENNOMIDiE. 
Under this family members of several quite distinct groups were associated by Messrs. 
Guenee and Walker. The family is typically represented by genera having the outer margins 
of all the wings more or less angulated — by which character alone can the Ennomidfe be 
distinguished from the Urapterygidaj. Up to the present time, however, a number of genera 
of Oxydiidte and CEnochronjiidte have been referred indiscriminately to either family, some 
to the Urapterygidfe and others to the Ennomidse. 
EPIONE, Blip. 
Epione gynopteridia. (Plate CXIV. fig. 1.) 
Epione gynopteridia, Butler, Ann. Sf Mag. Nat. Hist. ser. iS, vol. vi. p. 123. n. 23 (1880). 
Sandy yellow : primaries sparsely striated with ferruginous, and crossed by a slightly 
darker central belt bounded by angulated ferruginous lines, which diverge towards the costa ; 
apex (not including the frmge) ferruginous : secondaries with the basal area sparsely mottled 
with grey ; a central triangular band of testaceous, partly edged with grey and partly with 
ferruginous ; apical border and one or two streaks at the anal angle testaceous ; a small 
black dot on the centre of the second median interspace : head and sides of abdomen golden 
yellow ; collar testaceous ; antennse brown. Under surface golden yellow : wings mottled 
with ferr^^ginous, and crossed near the middle by a dark ferruginous line bounding internally 
a diffused and irregular copper-red belt ; fringe testaceous : primaries crossed near the base
