BUTTERFIAES COLLECTED IN THE TAVOY DISTRICT. 131 
on forewing; three black anal spots, the two outer crowned inwardly with 
metallic blue scales, the middle spot entirely covered with similar scales. 
This is evidently a new species but I hesitate to name it as I have not 
succeeded in taking a male. It probably belongs to the group anunda, Hew., 
auxesia, B.B., auxea, DeN., and is near auxesia, B.B., but differs from it in 
the obsolescence of the discal band on the underside of the forewings. It 
agrees fairly well with A. agesia, Hew., the spots on the undersides of both 
wings being much alike, but it differs from that species in being pale purple 
on the upperside while A. agesia is violet-blue. 
299, Arhopala tunguva, Gr. 8. 
Many specimens of both sexes taken on Pagaye hill, during December 1919. 
This species varies much in size and in the colour of the uppersides. 
300. Arhopala perissa, Doh. 
An uncommon species of which I secured only a few specimens. I took it 
on Pagaye hill at 600’ and also on Kalataung, 1,700’, in December . 
801. Arhopala perimuta, Moore. 
Plentiful on hill tops throughout the district during January and February, 
and less so at other times. 
302. Arhopala duessa, Doh. 
Found sparingly from November to March. I have a few specimens of 
both sexes, of which some were taken at Kalachaung in March and others 
on Kalataung, 1,500’, during December 1919. 
303. Arhopala ammonides, Doh. 
Several specimens of both sexes of this beautiful little butterfly were caught 
at Kalachaung in March and Myekhanbaw in April 1920, 
304. Arhopala arvina, Hew. 
Two males and one female taken on Kalataung,1,700’,on 21st December 1919. 
305. Arhopala adala, DeN. 
A single male taken on Pagaye hill, 600’, during December 1919. 
306. Arhopala fulla, Hew. 
A single female caught on Kambauk hill, 300’, on 14th January 1920, This 
species has previously been described from the Andaman Islands. 
Subfamily—DrvuporicIn#, 
307. Deudoryx epijarbas, Moore. 
Common throughout the district. 
308. Hysudra hades, DeN. @ No. XII in plate. 
A single female taken about two miles from Kambauk, on the road to Paeha- 
ung, on 16th January 1920. De Niceville, J.A.S.B., 1897, p. 500, described this 
butterfly as ‘hair brown above, paler on the disc,” which is not the case in 
the specimen I possess which has a distinct cupreous tint on the area below 
the cell of the forewings, from the base to about three-fourths the length of 
the wing. There is also a large dark spot in the cell, covering half the area 
of the same. The hindwings are less cupreous, but this colour is spread over 
the entire surface. 
309. Rapala sphinx intermedia, nov. & No. XIII in plate. 
Three males and two females were taken on Kalataung, 1,500’, on 22nd and 
23rd December 1919. The males on the upperside are exactly as in Rapala 
rhoecus, DeN., but on the underside they agree with Rapala sphinx, Fab. My 
male specimens have the discal band on the forewings, as in R. rhecus 
and though Swinhoe in Lep. Indica sinks rhecus to sphinx, he makes no 
mention of the discal band, On the underside my specimens differ from 
rhecus in having the ground colour dark brown and not olive green, This 
is no doubt an undescribed form between sphinx and rhecus.
