the Avings, and by the white markings and blackish ground-colour of 

 under surfocc of secondaries. 



Occurs sparingly in June and July at Ichang and Chang-yang in Central 

 China and at Chia-kou-ho in Western China. 



Satsuma chalybeia. (Plate XXX. figs. 7 $ , 8 var. j .) 



Saisuma chalybeia, Leecli, Entomologist, xxiii. p. 43 (1890). 



Male. Pale blue ; costa, apical third, and outer margin of primaries black, as also are the fringes ; 

 secondaries with an interrupted black submarginal band ; a broad black line before the black 

 and grey fringes. Under surface grej"^ dusted with black atoms, basal half of primaries 

 blackish; discoidal spot, central and submarginal wavy lines black; transverse band of second- 

 aries occupying the central third of wing, blackish, limited by black wavy lines ; submarginal 

 line black, undulating, followed by some obscure dusky spots. Eringes as above. 



Female. Similar to the male, but the black margins are more clearly defined. 



Expanse 32-33 millim. 



Differs from Sntsiima {Thecia) frivaldszkyi, Ld., in having two distinct 

 transverse lines on under surface of primaries, and in the absence of white 

 markings on under surface of all the wings. 



The above description of the male refers only to specimens from Chang- 

 yang, Central China, from which place I first received this species. I now 

 have male examples of *S'. chalyheia from several localities in Western China, 

 and as these differ from the type I describe the form as var. ylufo (Plate XXX. 

 fig. 8) : — All the wings blackish, the basal area tinged Avith blue in one speci- 

 men ; there is a pale blue submarginal line towards anal angle, and the anal 

 lobe is brownish ; under surface brownish. The female is similar to the same 

 sex from Central China. 



Occurs at Chang-yang, Central China, and at Wa-ssu-kow, Pu-tsu-fong, and 

 Chow-pin-sa, AVestern China. It flies in June and July. 



Satsuma nicevillei, sp. nov. (Plate XXX. fig. 9, .) 



Male. Black, with a dark bluish sheen in certain lights ; the basal area of all the wings greyish 

 blue, this colour extending in some specimens into the outer marginal area of secondaries ; 

 the glandular patch is large, elongate, dark ; the anal lobe is tinged with brownish, and the 

 abdominal margin above it is hollowed out; there are indications of a bluish line on the outer 

 margin. Fringe dark greyish. 



Female. Greyish blue ; the costa and outer margin of primaries broadly, and the outer margin of 

 secondaries narrowly, bordered with black ; anal lobe and excavation above as in the male. 



Under surface of both sexes : primaries oohreous brown, broadly streaked with grey along the inner 

 margin ; a narrow black transverse line from the costa, just beyond the middle of the wing,
