N0T:ES on butterflies from the nag a hills. 601 



of A. syama which 1 took commonly and from which it can be at once dis- 

 tinguished by the deeper colour of the blue on the upperside and on the 

 underside by the hook shaped streak in the cell. The forewing is also of 

 a different shape and more pointed. The two insects when placed side 

 by side look totally different. 



336. AplUXaeuS ru^ZUini, de N. — A single male taken at the foot of the 

 hills in April. 



337. HyPOlySBCaa erylUS, Godart. — Males very common at the foot 

 of the hills from March to November. Females rather rare. 



338. ClXliairiai OtllOUai, Hetoitson. — Three males obtained at the foot of 

 the hills from March to August. 



339. Cllliairia Ssiuai, Heioitson. — Three males taken at Kohima in 

 October, also four males and two females bred from larvse. I give the 

 transformations from larva to imago. 



At Kohima on 2oth September 1909 an orchid, Vanda coevulea, was brought 

 to me. On it feeding on the flowers were seven larvse. On 27th and 28th 

 four larvse left the flowers and descended to the leaves of the orchid where 

 they lay quietly on the upper surface of the leaves, three on one leaf and 

 one on another ; here they lay without moving till they pupated which 

 two did on morning of 29th, one on the evening of the same date and one 

 on the morning of the 30th. Two more left the flowers on 30th Septem- 

 ber and 1st October and pupated on the flower stem at its base close to the 

 leaves. The seventh died. 



The positions chosen seemed to be immaterial as some had their heads 

 downwards and some up. 



Larvse when full grown were about "Gl inches in length and of the usual 

 onisciform shape. Colour pale green with dorsal spiracular, super-spiracular 

 and sub-spiracular reddish mauve bands, all with the exception of super- 

 spiracular coalescing near 11th and 12th segments ; the dorsal band could 

 be distinctly seen to expand and contract with the breathing. 11th to 

 14th segments entirely reddish mauve. Head pale greenish yellow with 

 black eyes and when at rest drawn in under 2nd segment. Spiracles 

 black ringed faintly with yellowish ; prolegs tinged with reddish mauve ; 

 four dark dorsal dots on 2nd segment ; a gland on dorsum between 11th 

 and 12th segments exuding a crystal liquid eagerly sought after by at- 

 tendant ants ; the ant tickles the larva until it exudes a drop of liquid 

 which it immediately drinks up. The whole of the upper body covered 

 with short dark hairs. 



Whilst preparing for transformation to the pupal stage the reddish 

 mauve colour of the larva diminishes in intensity and when the larval skin 

 is cast oft' the colour of the pupa is pale green with the mauve stripes 

 showing faintly. The pupa lies flat on the upper surface of the leaf or on 

 the side of the raceme to which it is attached by the cremaster to a
