Zepliyrus coelistis. (Plate XXVII. fig. 9, 6 .) 



Thec/a coelistis, Leech, Entomologist, xxiii. p. 191 (1890). 



Male. Eriglit bhic ; primaries -with broad black band on outer margins, the apical portion 

 extending nearly to middle of the costa, from this point to the base the costa is edged with 

 black. Secondaries: two black spots just above anal angle (one on each side of submedian 

 nervure) ; the submarginal band is black and faiiiy broad at apex, and this colour is con- 

 tinued halfway up the whitish abdominal margin. Fringes greyish, preceded by a black line 

 on the secondaries ; tail black, tipped with white. Under surface russet-brown : on the 

 primaries there is an indistinct discal spot, and beyond it an obliciue silvery-white line 

 extending from costa to first median branch; submarginal line bluish white, ill defined 

 towards apex, and edged internally with black towards the inner margin, which is broadly 

 grey : secondaries have a silvery-white central transverse line and a bluish-white sinuous 

 submarginal line; the latter is edged internally with blackish, and the former is twice angu- 

 lated above the anal angle and terminates about the middle of abdominal margin; anal angle 

 is black, and above it is a broad orange-red patch extending from first median nervule to 

 end of central line on abdominal margin ; the black spots are reproduced, but that nearest 

 the anal angle has a blue centre : fringes as above, but the black line at their base is preceded 

 by a bluish one towards anal angle. 



Female. Similar to the male, but the black band of primaries is much broader and contains an 

 orange patch, which is bisected by the second median nervule ; the costa and fringes are 

 tinged with fulvous ; the marginal band of secondaries is also broader. 



Expanse 42 millim. 



Tar. nigricans. All the wings have a slight blackish suffusion, the apex and outer margin of 

 primaries are very broadly bordered with black ; the outer margin of secondaries is also broadly 

 black, and this colour projects from the inner edge of the marginal band along the nervules. 



Both forms occur at Ta-chien-lu, Omei-shan, and Moiipin, in June and July, 

 up to 8000 feet. The type has only been received from Wa-shan, Pu-tsu-fong, 

 and Ni-tou.

"Expands 1-25 to I'oO inch. The ground-colour of the wings in both sexes is dark brown; all 

 the wings have the fringes whitish brown. The head, thorax, and abdomen are black above, 

 but the legs and palpi are white beneath ; the antennfe are black, ringed with white. The 

 male has a faintly black oblong discoidal spot on the fore wings, and external to it a light 

 but inconspicuous patch ; the hiud wings have the tail orange, and a small orange patch at 

 the anal angle. The female differs from the male in having a large and bright orange patch 

 on the fore wings external to the discoidal spot, crossed by two or three black veins, and 

 occupying nearly a fourth of the area of the wings. The underside is nearly the same
