NOTES ON BUTTERFLIES FROM THE NAG A HILLS. 599 



The male differs from /. epicles in having on the upperaide the purple 

 coloration more extended, covering nearly the whole of both wings, and of 

 a duller shade ; on the underside the yellow is purer. The female only 

 differs on the upperside in having the red discal patch larger but as I 

 secured only a single specimen of this sex this may not be constant ; on 

 the underside it is paler and duller. Mr. Bethune-Baker who kindly 

 examined the genitalia for me writes : — 



'' I do not think they are the same (i.e., /. epicles and /. kohimensis). 

 The harpagines (clasps) are practically similar but the other parts have 

 distinct differences. The tegumen of yours has its lateral lobes quite twice 

 as broad and they are somewhat curved and have conspicuous tubercles 

 from which the hairs arise ; whilst the /a/ces (hooks) are angled about the 

 middle ; in epicleft the hookg are narrow and straight and the tubercles quite 

 inconspicuous, whilst the falces are evenly curved exactly like a sickle. 

 In yows the oedoeagus (penis sheath) is much longer and much more slender 

 than in epicles ; and again the cingula (girdle) is inclined strongly forward 

 whilst in epicles it is nearly erect." 



Fifteen males and one female were captured at 5,000 — 7,000 ft. from 

 September to December. It is not nearly so common as I. epicles and 

 ■flies at a much higher altitude. 



I was at first inclined to think that this might only be a well marked 

 local race of /. epicles but the differences in the genitalia point to it being 

 quite distinct from that species. 



326. Ilerda androcles, DouUeday and Hetoitson. — Taken commonly at 

 4,600 — 7,000 ft. from August to November. This is the commonest Ilerda 

 in these hills. 



327. Ilerda viridiPuaCtata, de i\^— Race Mia, n. PI. ii., fig. 4. Under 

 the above name I separate the form of /. mridipunctata found 

 in these hiUs from the typical form found in Sikhim and the N.-W. 

 Himalayas. On the upperside it differs in having the green powdery patch, 

 which is so conspicuous in the typical form, reduced to a mere 

 sprinkling of scales, hardly discernable in some specimens, giving the 

 insect a verj'^ black appearance ; these scales are also greener than in the 

 typical form. 



Mr. Elwes records it as being common in the Naga Hills at 6,000 ft. and 

 above. I only obtained it in November at 5,000 — 6,000 ft. when it was 

 rare owing probably to the lateness of the season. 



328. Ilerda brahma. Moore.— Very common at 5,000—7,000 ft. from 

 August to November ; a few specimens which are somewhat smaller were 

 taken in March at 4,000 ft. 



Aberration hybrida, n. 



Very similar to typical /. brahina but differs in the colour being brassy 

 green and the terminal red band on the hindwing narrower.
