TAJmiA DOMiNus, sp. 11. (Plate XXXIII. fig. 12 S •) 



cJ . Upperside brilliant shining cerulean blue, much Uke P. 

 cleobis, Godt., but more opalescent ; fore wing with the apex 

 broadly black and \^"ith a quadrate black " sexual mark " occupying 

 rather more than the outer half of the cell : hind wing — costal 

 margin greyish, darker towards the apex, which is black. Under- 

 side differs from P. cleobis by the ground-colour being darker, the 

 linear band being placed closer in, the black spots at the anal angle 

 being much larger, and the yellow being much more extensive and 

 confluent. The patch between the spots is dusted with metallic 

 scales.

T. dominus is allied to T. melasticjma \ de Nicev., but in that 

 species the " sexual mark "' is placed beyond the cell. It is also 

 much like T. cleoboides -, Elwes, which is described as possessing 

 only two subcostal nervules to the fore wing, whilst T. dominus 

 has three. Messrs. Godman and Salvin possess a specimen, which 

 I believe to be referable to T. dominus, \^hich differs only from 

 the type on the underside by the black spots being smaller and the 

 yellow less extensive : it is labelled " Biivmah."

(J . Allied to T. mantra, Pelder, but larger, and the outer 

 margin of fore wing convex. Upperside blue, sUghtly paler, 

 without the opalescence, and more extensive in both wings ; a 

 black spot in the lobe crowned with orange. Underside differs 

 from that of T. mantra <S by the ground being much paler, by the 

 linear band of the fore wing being narrower and indistinct, by the 

 • inner margin of the fore wing being broadly white for nearly its 

 whole length, and bv the orange patches at the anal angle of the 

 hind wing being of a deeper shade. 



5 . Differs from the male by the blue being of a slightly paler 

 shade and considerably more extensive in the fore wing ; the black

T. melastigma is described as having the " sexual mark " shining black, but in 

 the figure it is showTi as pale brown, much the colour of the underside. T. cleo- 

 boides is described as having " a large i-ound velvet patch free from blue scales 

 in the cell of the fore wing " — presumably a black patch ; but this does not 

 appear in the figure of the insect.
