NOTES ON BUTTERILIES FROM THE NAG A HILLS. 511 



Symbrenthia silana, de N. 



Seven males and two females of the w. s. f. were obtained at Kirbari 

 Naga Hills, at about 6000' in July, August, September and October. 

 Thirteen males of the d. s. f. were obtained near Sebong, Eastern Manipur 

 Hills, and on the Irang River, Western Manipur Hills, at low elevations in 

 February, March and April. This very distinct species can at once be 

 distinguished from S. nijjhanda on the up2)erside by the much broader yellow 

 markings and on the underside by (1) all the dark markings appearing very 

 much darker ; (2) the much broader band of the ground colour separating the 

 subterminal cones from the terminal markings ; (3) the very irregular 

 anterior edge of the terminal lunules in interspaces 2 and 3. 



S. silana is considered by some authors to be a race of 8. niplianda and by 

 others to be the d. s. f . of that species. L believe it is iindoubtedly a good 

 species. 1 have a single d. s. f. of S. niplianda taken at Phesima in the 

 Naga Hills in April which only differs from the w. s. f. in having the cones 

 •on the underside of the hindwing half the size and the pale discal band 

 rather broader. 



The d. s. f . of >S'. silana only differs from the w. s. f . in being rather smaller 

 and in having the rufous bands on the upperside if anything slightly 

 broader. On the underside the green of the subterminal cones on the 

 hindwing is carried on to the forewing, being distinct in interspaces 3 and 4, 

 less so in 2, 5 and 6. On the upperside hindwing there is also sometimes a 

 distinct fine reddish terminal line. 



The type which is in the de Niceville collection has the cones and lunules 

 •on the underside of the hindwing metallic blue, but it is aberrant in this 

 respect, the remainder of the specimens in the collection and all my 

 specimens have it very dark bluish-green. 



CiRRHOCHROA AORis, Doubleday. 



An hermaphrodite of this species was taken by Captain Porter on the 

 Dihang River, Abor Hills, in June, and kindly presented by him to me. 



The left pair of wings and left foreleg are male in character whilst the 

 right pair of wings and right foreleg are female. I have not examined the 

 genitalia very carefully but they appear to be male. 



Calinaga aborica, n. sp. (PL III, Fig. 21 J ). 



Male. Upperside black with pale cream coloured markings. Forewing: 

 two narrow pale streaks, irrorated with fuliginous scales, occupying basal 

 half of the cell and joined together towards the base ; the lower streak the 

 longer of the two ; two short contiguous similarly coloured streaks, placed 

 one above the other, towards the end of the cell, between which and the 

 bases of veins 3 and 5 are two more very indistinct pale spots ; a broad pale 

 streak, bifurcated at its outer half, in interspaces 1, commencing at the base 

 and extending well beyond the base of vein 2, the lower portion the longer ; 

 a long narrow pale streak at base of interspace 4 ; a discal row of narrow 

 pale streaks in interspaces 2 — 6 ; a subterminal row of pale cream spots in 

 interspaces 1 — 6, interspace 1 having two spots ; and lastly a terminal row of 

 very indistinct spots in interspaces 1 — 4. Hindwing : a broad pale streak in 

 cell, commencing at the base and not quite reaching the end, the outer two- 

 thirds bifurcated and dusted with fuliginous scales, the upper portion a little 

 longer than the lower ; two pale streaks dusted with fuliginous scales at base 

 of interspaces 4 and 5 ; a discal row of pale spots in interspaces 1 — 3 and 5—7, 

 the first very small and indistinct, those in interspaces 5 and 6 long and 

 linear ; a subterminal row of large pale spots in interspaces 1 — 6 ; basal half of 

 interspaces \-b and 1-a pale cream ; dorsal half of wing densely covered with
