Expanse, c? 3J to 4J, ¥ 4J inclies. 
Habitat. —Eastern Himalayas, Upper Assam, Cacliar, Khasia Hills, Burma. 
Our illustration on plate 48, fig. 1, represents a male from Darjiling ; fig. la 
is from the Burmese male type of Irawada , fig. lb of a female from Bassein, and 
the variety of the male, figured on plate 48, fig. 1c, is from Bangoon (taken in 
October, and now in the collection of Col. C. Swinhoe). On the upperside of the 
forewings this latter specimen has the usual costal, cell, and discal spots incipiently 
indicated by a few blue scales only, no submarginal or marginal spots are visible, 
and the sexual mark is narrower and shorter than in other Burmese specimens of 
T. splendens under examination. 
Distribution. —According to Mr„ L. De Niceville (Butt. Ind. 61) “ it is found, but 
not very commonly, in Assam, extending through the Eastern Himalayas as far as 
the valley of the Sardah, which separates Kumaon from Nepal. To the westward of 
this range it is much rarer than to the eastward. Mr. Wood Mason took both sexes 
in Cachar from April to June.” Mr. Otto Muller obtained it in Sikkim in June. 
Mr. L. De Nicdville ( J. A. S. Beng. 1881, 55) took “a single male in Sikkim in 
October.” In Burma it has been taken at Bassein in October. It occurs also in 
Rangoon and at Toungkoo. Major C. H. E. Adamson (Notes on the Danainae of 
Burma, p. 6) says, u I caught two specimens of this insect in March, 1883, on the 
edge of the Htaroony Choung, in Arrakan. In the same year I caught one male 
and one female soon afterwards near Akyab. Daring April, in the Arrakan Hill 
tracts, I found it flying abundantly in certain places. I also caught some 
specimens at Booseedoung, on the Mayoo river, in April, one male at Akyab on the 
15th May, and one on 26th June. The brilliant blue gloss is very apparent when 
on the wing, and so are the bright yellow caudal appendages of the male. As found 
in Arrakan this is a very constant species, both in colour and in the number and 
extent of spots. I have only taken one female.”
