Uale (micans, B. & G.). " Alis supra : can-iileo-iuicantibus ; posticis caudatis ; subtus cinereis, 

 linea nigra submarginali, externe albo-inarginata, angiilo imi maciilis duabus nigris, supra 

 cxtcrnam lunula fulva.

"Tlie upper surface of the wings is shining blue, and the hind wings are tailed. Under surface is 

 ashy grey merging into yellowish ; towards the middle of all the wings there is a short 

 indistinct line, which is bordered inwardly on the primaries, and outwardly on the secondaries, 

 with darker. A wavy black line runs from the costa of primaries towards the inner angle, 

 and from the costa of secondaries towards anal angle, before which it ends in a W-shaped 

 mark as in 2'. lu-ulhum, but the angles of the W are rounded ; there are two round black spots 

 at the anal angle and above the outer one is a yellowish luuular spot ; between these black 

 spots the ground-colour is darker and dusted with whitish." {Bremer Grey, I. c.) 



Female (ccerulea, B. & G.). " Alis supra : cajruleo-micantibus, posticis caudatis, duabus maculis 

 fulvis ante caudam ; subtus : fulvesceutibus, fasciis obscurioribus, stringis luteis interne 

 marginatis ; posticis fascia aurantiaca, ante caudam maculis tribus nigriS; media cinereo- 

 caerulco pruinosa.

" The upper surface of the wings is shining blue, with a fulvous spot at anal angle of secondaries, 

 and a similar spot is placed before the slender tail, which is an eighth of an inch in length 

 and is tipped with white. Under snrface of the wings ochreous yellow, discoidal bar of 

 primaries bordered with paler and transversely bisected by a pale line ; beyond the cell is a 

 dark baud, bordered with paler, which runs obliquely from the costa towards inner angle. 

 Parallel with the fringes is a broad dark band which is traversed throughout by a paler line. 

 The secondaries are marked similar to the primaries, only the inner band terminates towards 

 anal angle in a black zigzag line bordered with white as in T. lu-alhum; the submarginal 

 band terminates in a longitudinal orange patch bordered outwardly with white and enclosing 

 three black spots, the first and third of these spots are round, and the second lunular and 

 sprinkled with blue." {Bremer 6," Grey, I. c.) 



Var. betuloides, Butler. (Plato XXVII. fig. 13, d' .) " Above chocolate-brown, shot with purple, 

 excepting on the outer border ; primaries with a large patch of bright orange on the disk imme- 

 diately beyond the cell : secondaries with an orange patch at the anal angle. Under surface 

 grey ; the cells closed by a short brownish fascicle with darker marginal lines edged externally 

 with white ; an oblique discal band and a second band nearer and parallel to the outer margin 

 of the same colours ; a submarginal dusky stripe, followed in the secondaries by a white mar- 

 ginal line ; base of fringe occupied by a black line : secondaries with an orange anal patch 

 enclosing a black dot on the first median interspace ; a subanal W-shaped blackish line joining 

 the inferior extremity of the inner discal baud, its inner edge bordered with orange and its 

 outer edge with white ; anal lobe and tail black : pectus white, venter testaceous. Expanse 

 of wings 1 inch 4-6 lines. 3 sp. Kiukiang, China." {Maries.)

 simply remarks : ' In the neighbourhood of Pekin an allied species exists which
