TEINOPALPUS. 9 



replaced by a very much larger dark grey patch, below which com- 

 paratively narrow markings of yellow extend up to the dorsum ; a 

 postdiscal sinuous lunular narrow black band and a subterminal 

 .series of green lunules as in the J, but the apical lunule dark grey, 

 not yellow ; the tail-like extensions of the termen at the apices of 

 veins 3 to 6 are black shaded with green, those at the apices of 

 veins 4 and 6 tipped, the former with yellow the latter with greenish- 

 white. Underside similar to the underside in the c? , but on both fore 

 and hind wing the areas coloured with rich ochraceous and yellow 

 are grey, with the exception of a well-marked moderately broad 

 subterminal band on the fore wing which is of a dull ochraceous 

 colour; on the hind wing the grey discal area extends right up to 

 the apical lunule of the subterminal series. Antennae, head, 

 thorax and abdomen as in the J .

The larva of this magnificent butterfly, according to Mr. Knyvett, 

 feeds on Daphne nipalensis, but so far as I know, no description of 

 it has been published. 



I am quite unable to separate the Sikhim form of this insect, 

 even as a race. The points of difference between it and the Assam 

 form are extremely variable, and the most prominent of these, 

 viz. the paler tint of the grey area on the upperside of the hind 

 wing in the 5 , is perhaps the most variable of all the characters. 



An Assam specimen of the $ in the collection of the British 

 Museum is far and away paler than any Sikhim specimen I have 

 seen. 



Mr. Elwes says that in Sikhim this insect is only found in the 

 forest region from about 6000 to 10,000 feet elevation, and that 

 " it is most difficult to capture on account of its remarkably strong, 

 rapid and dashing flight, and its habit of resting on high trees, 

 from which it flies only during a few hours of the morning " 

 (Elwes, Trans. Ent. Soc. 1888, p. 421). 



The females are much scarcer than the males. I once saw a 

 $ on the wing and rather low down, in a clearing on the hill 

 above the Eungarun Porest bungalow near Darjiling. According 

 to Col. Swinhoe, T. imperialis is common in the Khasia Hills in 

 Assam.
