with two pairs of spurs, the first, pair being situated in the second third ot the tibia. Abdomen of cf with hairy 
tail. The 1 st radial of the hindwings wanting, the 1 st median far from the tip of cell. From India to the Amur. 
bipars. T. bipars Walk. (8f). cf and ? similarly colored. Rody above with a more or less faint metallic 
green sheen, especially the abdomen. Tongue yellow red. The narrow forewings purple brown, faintly bluish: 
2 nd median indicated. The triangular hindwings are transparent, the borders and portions of the veins brown 
black. North India: Simla, Kangra, Khasia and Naga Hills in Assam. 
longipennis. T. longipenrsis IIamps. Very similar to the former species, somewhat smaller, tongue yellow; the 2. 
median of the forewings completely developed up to the border; the hindwings with considerably more scaling 
in the centre of the wing, only half transparent, and the thinly scaled portion is not sharply defined. Bernardmyo, 
Burmah, 6 —7000 ft. in May; one cf in the Elwes collection. 
7. Genus: Araeocera Ramps. 
Forehead slightly arched. Antennae in the ? simple. Palpi very short. Rear tibia with one pair of 
short spurs. Forewings long and eliptical, all the veins in both wings arising from the cell; the 1 st radial of 
the hindwings wanting. Indo-Malayan. The cfcf not known. 
cyanescens. A. cyanescens Ramps. (81). Black. Forewings black with bluish tinge very faintly metallic; hindwings 
blackish brown. Undersides of both wings brown, the costal vein, the fringes and the border faintly greyish 
blue. 1 ? in the Elwes collection from Momeit Burmah. 
compia. A. compta spec. nov. (8f). Brownish black; Antennae, head, collar, a few spots on the thorax and the 
whole upperside of the abdomen shining greenish blue. Abdomen beneath purple, here and there shining 
greenish blue. Uppersides of the forewings with four small greenish blue spots, one is situated on the cross 
vein, a second smaller outwards from it, and two before the hind border, moreover the costal border and the 
cell are dusted with greyish blue scales for about one third of the length of the wing. Both wings beneath 
have blue scales in the neighbourhood of the costal margin. Length of wings 10 mm. A ? from South 
Flores, November (S)ry season), in the Tring Museum. 
8 . Genus : Ill i foeris Walk. 
Like Phacusa but the 1 st radial of the hindwings present. Chiefly eastern palaearctic, only two species 
up to the present having been found south of the Himilayas. Larva resembles that of Procris, with low broad 
tubercles, which bear short hairs. In the Japanese I. pruni ( 1905) the upperside is pale, the underside reddish, 
a dorsal stripe and a subdorsal row of spots are black; head with black markings. Coccoon white, fastened 
amongst leaves. Food plant: Pirus communis. 
diaphana. I. diaphana Ramps. Black, antennae faintly blue; wings transparent with thin black scales, hind border 
of forewings and costal border of hindwings more thickly scaled both above and below. Forewings pointed, 
the border very oblique, the scaling is not increased on the oblique end of cell, all veins arise from the cell, 
the 1 st median from the lower corner, the 2 nd subcostal nearer to the 3 rd than the 1 st . Hindwings triangular, 
border faintly but distinctly hollowed, the upper corner of cell situated somewhat more distally than the lowrnr. 
Benardmyo, Burmah 6000—7000 ft., in May; 1 a 71 in the Elwes collection. 
fuliginosa. I. fuliginosa Moore. Greybrown, without markings. Forehead not arched; tongue pale yellow; palpi 
and legs short, dirty yellow gtey, the latter not ringed with brown. Hind tibia with one pair of spurs. 
Antennae of the ? slightly pectinated. In the forewings all veins arise from the cell, in the, hindwings the 
1 st radial is present, the 3 rd radial and the 1 st median arising together. Fringes not paler than the rest of the 
wings Darjeeling, one ? from the Moore collection in the British Museum. 
9. Genus: Phat’usa Walk. 
Antennae of both cT and ? pectinated to the tips, palpi very short. Forehead not protruding. Spurs 
of the middle and rear tibia short, the latter with only one pair. Forewings long, generally the 2 nd and 3 rd or 
the 3 rd and 4 th subcostal nervures are stalked together, sometimes all arise from the cell. In the hindwings the 
1 st radial is wanting. It chiefly differs from Illiberis through the absence of the 1 st radial of the hindwings. 
China, India and known eastwards to New Guinea. 
P. nigrigemma. ?: antennae shining blue, pectinations longest between the centre and the tip. Head 
and a few spots on the thorax also brightly metallic. Abdomen behind and on the sides green; anal ring 
folded, clay yellow. Forewings transparent, the base, borders and a streak on the cross vein black. Hindwings 
rounded at the apex, black, with transparent spots. All the veins arising from the cell. In the Chinese form
