474 SPHINGIDiE. 



c£. Penis-sheath (fig. 120 D) differing from that of aurifera 

 in being more asymmetrical, and in the right process being 

 broader and having teeth along the proximal and apical 

 edges. 



Hab. W. and E. Himalayas (Mussooree ; Sikkim ; Assam). 

 We have bred the species in Mussooree in the W. Himalayas at 

 an elevation of 7,000 feet, and in the Khasi Hills at 5,000 feet. 

 The larvae are rather rare, and are found only in densely 

 wooded areas with a heavy rainfall. 



Larva : — 



Final instar. Very similar to that of aurifera ; horn tapering 

 evenly to a point, sides not flattened. Surface as in aurifera. 



Coloration. — Head and segments 2 to 5 green with a yellowish 

 tinge on dorsum, rest of body very pale bluish, nearly white ; 

 a narrow green dorsal stripe from 2 to base of horn ; a broader 

 white dorso-lateral stripe from 3 to base of horn, broken by 

 the ocellus on 5, and on 6 to 10 broken before the hind margin 

 of each segment, curved convexedly dorsad and edged above 

 with green, from 11 running straight across 12 to base of horn ; 

 ocellus on 5 longitudinally elongate-oval, pupil elongate -oval, 

 deep blue in front, sap-green behind, the green part bearing 

 two or three large white dots placed longitudinally ; the pupil 

 edged broadly above, less broadly elsewhere, with white, 

 the whole edged narrowly with sap-green ; front edge of 

 ocellus encroaching on to 4 ; broad, pale blue oblique stripes 

 on 6 to 10 running into the dorso-lateral stripe above. Horn 

 purple ; legs pink. Spiracles whitish with a brown patch 

 on each side of the central slit, and a narrow dark green rim. 

 Length 90 mm. ; breadth 11 mm. ; horn 7 mm. 



Pupa. — Very similar to that of aurifera. 



Habits. — Food-plants : Vitis Linn., family Ampelideae.

Rhagastis lunata sikhimensis, Roths. & Jord., 1903, p. 797 (Sik- 

 kim) ; Seitz, 1929, p. 569. 



Imago. — $. Differs from R. I. lunata in the following respects : 

 metanotum without reddish -tawny spot ; lateral stripe 

 of abdomen less red. Wings broader ; pale band of hind wing 

 with six brown dots, the last upon M 2 distinct, fringe without 

 white scales between R 1 and M 2 . Underside of wings more 

 distinctly ochreous distally, the brownish -black basal area 

 of fore wing just entering cell, continuous with the black discal 

 dash situated between R 2 and R 3 . 



Left process of penis-sheath longer and more hand-shaped 

 than in J?. I. lunata. 



Hab. E. Himalayas (Sikkim). One $ in Tring Museum, 

 $ and early stages unknown.
