distributed in Asia, IVoiu West and Central China throughout the Himalayas to Kashmir and North-West 

 India, as far the country is mountainous. The species appears to be absent from the plains, but closely 

 allied forms occur on the mountains in the Malayan subregion. The butterflies are local according to 

 DE NiCEViLLE, but not rare, their habits being as described above. The specimens from the northern districts 

 have sometimes no trace of yellow on the anal lobe, differing therein from Kashmir specimens. A further 

 aberration is characterized by the appearance of a distinct orange or brick-red spot beyond the cell of the 

 forewing: this spot may occur among specimens from all parts of the area of distribution. This form, which 

 was already figured by Kkwifsox, may be named ab. nirftulata ab. mi: (72 a). In China «/s.srt flies in June maculata.

 broad and pointed, the blue sheen less extended in the cf and nearly absent in the ?. On the underside the 

 band situated in the outer third is paler outwardl}-, being here almost whitish and on the hindwing of the 

 cT double; the abbreviated discocellular are indistinct or absent, the anal lobe on the other hand more 

 brightly and conspicuously coloured and marked. Also in this species there occur specimens which have a 

 reddish yellow cloud on the forewing beyond the apex of the cell, but this patch is as a rule less large 

 and bright than in many nhsa, and there occur all intergradations between the spotted and non-spotted form. 

 This aberration may be called ab. nebulifer ah. nor. On the iipjier and middle Yang-tse-kiang, on \he nehnlifer.

 bright blue gloss above, especially in the o''. The underside more yellowish grey, the dark discal lines 

 blackish: the anal lobe of the hindwing usually less produced. Common throughout China, except the south; 

 also in the plains. — ab. betuloides LeecJi (72 a) is the form with a large red discal patch on the forewing. betulaides. 

 already mentioned by Blanchard; the anal area of the hindwing, moreover, bears a red halfhand. Tran- 

 sitions from ab. betuloides to micans are plentiful.

 of the forewing blackish. This form has a superficial i-esemblance only to Deudorix epijarbas, the underside, 

 however, is uniformly brownish grey, not bearing numerous white curved lines as in D. epijarbes. Specimens 

 with the veins of the forewing black are considered by Blitlior to be ab. jarbas /''. According to Mooke Jorhas. 

 both forms occur together in the north-western Himalaya, which statement dk Niceville was apparently 

 justified in doubting, Jarhas being probably the eastern (Sikkimese) race. — Nymotypical iiieldinpiis occur 

 in Kashmir and possibly also in Afghanistan, the eastern form being widely distributed in India and ex- 

 tending southward to Malacca and Java. Larva flat, yellowish brown, marked with black, a subdorsal and 

 a lateral row of small warts bearing a tuft of small black hairs. Pupa small, of the ordinary T^ycaenid 

 shape, yellowish brown, spotted with black, anteriorly rounded, abdomen pointed. The butterflies are on 

 the wing from July until October, in India probably all through the year, being plentiful where they occur. 



• 2. (Tenus: Hysilflra Moore. 



Close to the preceding genus, but the head smaller, the forewing less pointed, and the o^ without 



the tuft of hairs at the hindmargin of the forewing beneath. — The genus contains but a single species, 



which appears to be restricted to Kashmir and the neighbouring districts of the western Himalayas. It 

 was formerly considered to be the ? of Rap. nissa.

 blue gloss; the forewing with a large, anteriorly straight, orange-yellow patch, above which there is often 

 an additional spot; a halfl)and of the same 'colour at the outer margin of the hindwing. Underside brownish 

 ash-grey, orange in the anal area of the hindwing, with a small black spot before the tail and a larger one 

 on the anal lobe on a reddish yellow ground. On the whole resembling Rnpala micans ab. bitidoides above 

 and beneath, but recognizable by the lesser size, the shape of the wings, the anteriorly straight patch on 

 the forewing and the absence of the scent-tuft on the hindmargin of the forewing in the o"", there being in 

 Hijsudra only an indistinct scent-spot in the middle of the costal margin of the hindwing. The insect can 

 be distinguished from the specimens of Rap. nissa with a large reddish yellow patch (ab. maculata) by the 

 hindwing being larger and having the outer margin more strongly con\ex. Larva presumably on wild Indigo 

 (Indigofera atropurpurea). on which Mackinxon saw a ? lay its eggs. — In Kashmir and the adjacent Hima- 

 layan countries, in Tibet and i)rohabl\- extending into China. In Kashmir the species hibernates as imago, 

 ovipositing in the spring. 



3. Geniis: Deudorix Hew. 



Essentially the same as the preceding genera, with a large head, broad whitish frons and short 

 ])alpi. But the antennae are much longer and reach in many cf cf beyond -/s of the costal margin. Shape 

 of wings as in Hysudra. the hindwing with a small rounded anal lobe and a rather long but hair-like tail.
