51. Genus: Xenoclilaena Lower. 
Face smooth, projecting somewhat. Palpus twice diameter of eye, terminal joint in $ % of second 
joint. Antenna of $ bipectinate to about 4 / 5 . Thorax and abdomen not crested; thorax hairy beneath. Hind- 
tibia of d without median spurs. Hindwing without rounded costal expansion at base, frenulum well developed 
in d- Fore wing with discocellulars strongly incurved, strongly oblique posteriorly; 1st subcostal from cell, 
free, 2nd —5th stalked, 1st radial shortly stalked with them, 1st median separate. Hindwing with costal 
approximated to cell near base, gradually diverging, 1st radial long-stalked with subcostal. 1st median 
separate. These particulars are given in a recent revision by Goldfinch; I have never seen the only known 
species, porphyropa. 
X. porphyropa Lower (= porphyropis Lower). “Pectinations about 1 y 2 . Forewing pale lilac mixed 
with purple; a broad ferruginous-red fascia, edged on both sides throughout by a line of ochreous; proximal edge 
nearly straight, from 2 / 5 costa to middle of inner margin; distal edge from beyond 3 / 5 costa to beyond middle 
of inner margin, angulated outwards in middle; ground-colour on either side of the fascia darker; a fuscous 
lunate discal spot; fringes deep purplish, terminal third sharply whitish. Hindwing rounded; lighter towards 
base; a faint darker lilac median fascia. Forewing beneath pale lilac, becoming ferruginous towards apex. 
Hindwing as forewing but median fascia becoming ochreous-ferruginous on costal half.“ Broken Hill, New 
South Wales. 
52. Genus: TTliociiemis Warr. 
This beautiful genus, the parent of the well-known Gomibaena, resembles it in shape, coloration and 
pattern, in the structure of the palpus and the antenna, the hairy breast and femora, tufted tibiae, etc. 
Differs in the better developed $ frenulum, crested metathorax and abdomen and sometimes in the absence 
of the proximal spurs of the hindtibia, which, moreover, is not dilated in the <$. Antenna of the $ pectinated, 
which is only rarely the case in Gomibaena. Larval habits as in Gomibaena and Euchloris. Distributed through 
a great part of the Indo-Australian Region, but not rich in species. 
A. Hindtibia with 4 spurs. 
U. biplagiata Moore. Except in the tibial armature remarkably close to castalaria Oberth. (Suppl. 4, 
Taf. 1 c), with which it was formerly united. Hindwing with postmedian slender and slightly incurved between 
the 3rd radial and 2nd median (in castalaria here thick and quite straight), apical spot of hindwing brighter, 
predominantly reddish or orange. Ceylon (type), the Greater Sunda Islands and Celebes. —- subornataria Rothsch. 
( = ceramicaria Obertli.) is a larger form from Ceram. - elegans Warr. (lib). Generally not larger than biplagiata ; 
antemedian line of forewing less acutely angled; apical patch of hindwing often reduced and coloured more 
nearly as in castalaria. New Guinea, Louisiades and N. Queensland. unidentata Prout, (= rookaria Oberth., 
cassidara Pagenst., nec Guen.) differs from elegans in having the blotches generally larger, the postmedian line 
of the hindwing with a pronounced tooth outward on the 2nd median. Described from Rook Island, but distri¬ 
buted in the Bismarck Archipelago. — negligens Prout, from St. Matthias Island, has all the white markings 
extremely slender, the subterminal in particular almost obsolete. Hindwing with the apical patch slightly 
shortened. — The larva of biplagiata has been found in Ceylon feeding after the manner of Gomibaena pustulata; 
it is yellowish drab, rather stout, the segments provided with paired fleshy processes, to which it attaches small 
pieces of withered leaves and flowers; it rests with the body much bent. 
B. Hindtibia with 2 spurs. 
U. castalaria Oberth. ( = cassidara auctt., nec Guen.) (Suppl. 4, pi. 1 c). This well-known Khasi species 
was long misidentified as cassidara, notwithstanding its disagreement with Guen el’s description in several 
particulars; see Gomibaena. Besides N. India, castalaria is known from the Malay Peninsula, Tonkin and W. 
China. 
U. woodfordi Warr. Very similar to castalaria (Suppl. 4, Taf. 1 c), forewing with the postmedian line 
straighter and the blotch at anal angle wanting. Solomon Islands. 
U. partita Walk. (= felicitata Walk., concisiplaga Walk., calliptera Meyr., doddaria Oberth.) (11 b). 
Distinguishable from all other Uliocnemis by its angled hindwing, with large white patch at anal angle. Variable 
and widely distributed — Ceylon, India, Tonkin, Malaysia, SambaWa, Philippines, Buru, Queensland, New 
Guinea, etc. If races prove separable, the name partita will apply to the Indian, concisiplaga to the Malayan, 
felicitata (= doddaria) to the Australian and calliptera to the New Guinea.
