" Alar. exp. 1" 7'". Bab. Japouiam." 
Female. " Very closely allied to B. taxUa, Brem. The fore wings are brown, darker at the apex 
and along the hind margin, and possess in the male [female] a yellowish square patch at the 
end of the cell, which is continued obliquely iu 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 B. iaxila, 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 iu the allied 
species." {Murray, 1. c.) 
The male of oriental is is referred to by Janson (/. c.) as follows: — 
" Although Mr. Mui-ray 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. japonica, being of a brilliant green above, paler than in that species, and 
without the black external margin to primaries, the underside agrees perfectly 
Avith the female. 
" This is a much rarer species than japonica, and the male was not 
discovered until last year [1876], when Messrs. Fryer 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. Fryer 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 Wa-ssu-kow^, Moupin, and 
Ta-chien-lu in AVestern China, and from Chang-yang, Central China. 
Var. SUfifusa, var. nov. (Plate XXYII. fig. 14, cj.) 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 
submarginal 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 discoidal spot on primaries, and 
the inner white line of the submarginal pair on secondaries is placed near the central baud 
consequently it is farther removed from its companion than in the type.
