re-discovery is therefore very interesting. A large series of males and 

 females w^ere taken by my native collectors in the Naga Hills at Phesima 

 and Kirbasi in July and August and a few in September and October. Two 

 males and a single female were taken at Suroifui, Manipur, at 7,000-8,000 

 feet in June and July. 



The $ 2 of the syla-khasia group are all very much alike on the upperside, 

 but fortunately the markings on the underside are constant and distinctive 

 and so there is no difhculty whatever in separating them. 



Thecla saittta, n. sp. (PI. Ill, Fig. 25, $ ). 



Female. Upperside : dull brown. Forewing : unmarked. Hindwing : a 

 black submarginal spot in interspace 2 irrorated with a few pale scales ; anal 

 lobe black irrorated with bluish-white scales and crowned with white ; a dark 

 anteciliary line inwardly margined with white towards the tornus. Two 

 narrow tails, the upper one short, the lower one long, black tipped with 

 white. Underside : ground colour pale buff'. Forewing : discocellulars indis- 

 tinctly marked with white ; a very narrow white postdiscal line margined 

 with brown and broken at veins 2 and 4, a submarginal row of black spots in 

 interspaces 1-5 ; the one in interspace 2 the largest, its outer half 

 orange ; an anteciliary black line inwardly bordered narrowly with 

 white. Hindwing : a white streak closing the cell bordered on both sides 

 witli darker colour ; a postdiscal narrow white band as on forewing broken at 

 v^ein 4 and forming a " W " and ending on the tornus ; a submarginal row of 

 lunular orange spots inwardly crowned with black and bordered inwardly 

 and outwardly with white, a large black spot in interspace 2 contiguous to 

 the orange lunule; anal lobe black ; apex of interspace 1 irrorated with bluish- 

 white scales ; an anteciliary dark line inwardly margined with white. Cilia : 

 basal half white, outer half biown. Eyes hairy. 



Expanse: $ 1- 3". 



A single female was taken at Saitu village, 4,000 feet at the Northern end 

 of the Manipur Valley, in May. In general appearance it is very like to 

 T. sassanides but can at once be distinguished by the two tails on the 

 hindwing. 



Ilerda mookei, Hewitson. 



Amongst numerous specimens of Ilerda androcles taken by my native 

 collectors at Suroifui, Manipur, were two specimens very near /. moorei. 

 They are slightly paler than typical specimens from Sikkim but 

 are pure bkie and never green in any light. They may possibly 

 be an aberration of androcles but are probably an eastern race of 

 moorei. My collectors *vere collecting near Suroi village from 5,000 

 feet to 9,000 feet and these two specimens may have been taken at 

 the summit of Suroifui at about 9,000 feet which would be too high for 

 androcles but not for moorei which flies at high altitudes in Sikkim. 



Aphn^us sani bvansii, n. sub sp. 



In my " Notes on Butterflies from the Naga Hills," published in the J.,B. 

 N. H. Soc, Vol. XXI, page 600, and pi. ii., fig. 5, No. 335, I recorded and 

 figured a form of Ai^hnceus near to A. sani. I have since compared this form 

 with specimens of A. sani in the DeNiceville collection and find that they 

 agree in every respect except that they lack the red spot on upper forewing 

 which is present in all DeNiceville's specimens from Sikkim. I have since 

 taken eight more J c? in the Naga Hills in June, September and October and 

 a dry-season S at Sebong, Manipur, in April. They all lack the red spot 

 completely and I have therefore under the above name separated the Assam 

 and Burma race from the Sikkim form.
