Female. " Very closely allied to D. taxila, Brem. The fore wings are brown, darker at the apex 

 aud along the hind margin, and possess in the male [female] a yellowish square patch at the 

 end of the cell, which is continued obliquely in the direction of a point on the hiud margin a 

 little above the anal angle. This portion is ill defined. On the underside the pattern of 

 the wings much resembles that of D. taxila, but the transverse streak of fore wing is longer 

 than in that species (judging from Bremer's figure), and the streak on the hind wing is 

 distinctly angulated in the form of a W, which does not appear to be the case in the allied 

 species." {Murray, I. c.) 



The male of orientalis is referred to by Janson (/. c.) as follows: — 

 " Although Mr. Murray states his description is of the male of this species, 

 it is evident he had never seen that sex, as several individuals recently 

 received from Japan exhibit a similar sexual dissimilarity to that extant in 

 T. jajjom'ca, being of a brilliant green above, paler than in that species, and 

 without the black external margin to primaries, the underside agrees perfectly 

 with the female. 



" This is a much rarer species than japonica, and the male was not 

 discovered until last year [1876], when Messrs. Pryer and Jonas took several 

 in company with the females near Yokohama." {Janson, I. c.) 



The larva, according to Dorries, is ash-coloured, and feeds on oak. 



Occurs plentifully all over Japan and at Gensan, Corea, from the end of 

 June to the beginning of August. Pryer gives Yokohama, Asama-Yama, 

 Nikko, and Yesso as localities, and says that it appears at the same time as 

 T. japonica. I have received the species from AVa-ssu-kow, Moupin, and 

 Ta-chien-lu in Western China, and from Chang-yang, Central China. 



Var. SUfFusa, var. nov. (Plate XXVII. fig. 14, S .) Male. Bluish-green, with a strong 

 purplish- grey suffusion, in certain lights the green colour is only apparent on the costa and 

 outer margin of primaries. Primaries have a moderately broad black border, suddenly 

 increasing in width from below first median nervule to inner margin. Secondaries are 

 broadly bordered with black, but the inner edge is not clearly defined ; there is no blue 

 submargiual line as in the type, the tail is also broader and rather shorter. Under surface 

 pale drab ; the markings very similar to those of the type, but the white ones are broader 

 and the dark ones less conspicuous ; there is no trace of a discoidai spot on primaries, and 

 the inner white line of the submargiual pair on secondaries is placed near the central band, 

 consequently it is farther removed from its companion than in the type.
