NOTES ON BUTTERFLIES FROM THE NAGA HILLS. 513 



A. angulata, Moore, which occurs abundantly in the Manipur Valley is a 

 very different looking insect and will prove to be a good species and not a 

 race of echerius. 



Family— PAPILIONID^ . 



Papilio doubledayi cacharensis, Butler. 



Not uncommon on the Barak and Irang Rivers in the Western Manipur 

 Hills. Dry-season forms were taken from February to April and wet- 

 season forms from July to October. P. cachare?isis appears to have been 

 described from the wet-season form ; the dry-season form which has all the 

 white markings much larger is almost identical with P. doubledayi. 



Papilio kabrua, n. sp. 



Very close to P. polla^ de N. and P. latreillei, Don., from the former it 

 differs in the following respects : — 



Male. Fore wing : proportionately broader, in this respect resembling P. 

 latreillei. Hindwing : white spot in interspace 5 on both sides much smaller ; 

 cilia between tornus and apex of vein 3, at apex of tail and at apex of 

 vein 5 black and not vermilion red, in this respect again resembling P. 

 latreillei. The outer edges of the white spots on the hindwing almost 

 straight and not deeply excavated as in P. polla. 



Female. Forewing : similar in shape to that of P. polla 5 • White spots 

 on hindwing as in male but outer edges even straighter ; cilia black as in 

 male. 



From P. latreillei S it differs on the hindwing in having an additional 

 large white spot in interspace 6 and the spot in interspace 4 completely 

 filling the base of that interspace. On the upperside there is no trace of a 

 subterminal white spot in interspace 6 ; this spot is also generally wanting 

 on the underside but is sometimes present. 



Expanse: ^4-64"; $ $ 4-5— 5-36". 



A single male taken at Yakama, Naga Hills, at about 7,000 ft. in June and 

 nine females taken in Manipur at 5,000 — 8,400 ft. in May and June. 



Papilio polla, de N. 



Two males taken at Saitu, Manipur, in May and a female at Poona, 

 Naga Hills, at 8,000 ft. in June. Both this species and P. kabrua appear to 

 be single brooded and are only on the wing in May and June. 



Expanse : S S 5-28— 5-7" ; $ 5-36." 



Papilio crassipes, Oberthur, 



Seven males and one female were obtained in the Western Manipur 

 Hills at about 3,000 ft. in March and June and two males at the head of the 

 Manipur valley at 3,300 ft. in July and September, also two males at 

 Nichuguard, Naga Hills, in April. 



Expanse : S 6 4-46— 4-94" ; $5-3" . 



Papilio alcinous iMPEDiEi^s, Rothschild. 



Many males and several females of a form of P. alcinous which agree 

 fairly well in the Seitz's figure of P. impediens, Rothsch., were taken by my 

 Native collectors near Kohima in the Naga Hills during May and the 

 beginning of June at 7,000' ; and three males in the ZuUa Valley in June. 

 Many of the specimens were unfortunately badly damaged and probably 

 fresh specimens will be found flying at the beginning of May. 



I am unable to say without comparison with the type whether the present 

 form is typical P. impediens or is another race of the variable P. alcinous..
