﻿NEW SPECIES OF LEPIDOPTERA FROM CHINA. 39 



lOLAUS CONTRACTUS, Sp. 11. 



$ . Black, ornamented with bright dark blue, which on the primaries 

 forms a patch extending from the base to the middle °of the disc between the 

 median and submedian nerves, slightly encroaching beyond each boundary. 

 On the secondaries the blue forms a broad oblique abbreviated band, its an- 

 terior limit being the second subcostal nervule, and its posterior the first 

 median, but there is a small triangular mark beyond this latter boundary, 

 extending to the orange spot at anal angle ; there are some black spots 

 towards the outer edge of the blue band ; the abdominal margin is paler, 

 becoming whitish at the base. There are two tails of equal length, both 

 black with white tips. Under surface of primaries whitish grey ; discoidal 

 spot linear white ; central transverse line blackish, terminating at the sub- 

 median nervure ; submarginal line indistinct ; on the middle of inner margin 

 is a fan-like arrangement of long dai'k grey hairs ; central transverse line of 

 secondaries wavy, turning off at a right angle to abdominal margin when 

 opposite anal angle ; outer margin bordered with dark grey, intersected by a 

 band of ground colour ; a large black spot on the outer edge of a round orange 

 patch before the first tail, and one at angle preceded by an orange streak. 



5 . Greyish black, with a patch of pale lilac-blue on the disc of 

 primaries, and some scales of the same colour towards outer margin of 

 secondaries ; fringes grey. On the under surface the lines are more distinct, 

 and the spots larger. In one female specimen the lilac-blue is only shown on 

 the primaries as a discal suffusion. Expanse, $ 38 mm., $ 40 — 42 mm. 



Allied to I. iapyx, Hew. 



Thecla elwesi, sp. n. 



$ . Fuscous brown, the discal area of primaries tinged with reddish 

 orange, especially behind the black bar which closes the discoidal cell. 

 Secondaries with some black spots and orange marks on outer margin at 

 anal angle; tail reddish orange, edged with black and tipped with white. 

 Under surface sandy brown, dusky discoidal bar edged with white, followed 

 by an oblique triangular streak darker than the ground colour and bordered 

 on each side by a white-edged dark line ; a dusky line, edged externally with 

 paler parallel with outer margin ; secondaries with two white central trans- 

 verse lines, the first edged externally with dusky and not extending beyond 

 the median nerve, the second slightly wavy, bordered internally with dusky, 

 and curved inwards beyond the second median nervule ; outer margin 

 bordered with reddish orange, edged internally with pale ochreous, wider 

 towards anal angle, the orange colour extending halfway along the ab- 

 dominal margin ; a black spot at anal angle and one in the second median 

 interspace ; fringes white, preceded by a black line which traverses the tail 

 to the white tip. 



$ . Orange-brown, clouded with greyish brown towards the base of all 

 the wings, apex and outer margin black; a black spot on secondaries iii 

 second median interspace ; fringes whitish, grey at the base and extremities 

 of nervules. Under surface of primaries reddish orange, secondaries rather 

 browner ; markings as in the male, except that the first transverse line of 

 secondaries extends farther across the wing. Expanse 50 mm. 



One female taken in July, and two males captured in August, 

 at Chang Yang. Also two female specimens taken in the latter 

 month, at Ichang ; these have the basal half of all the wings 

 suffused with greyish brown, and the marginal border of primaries 

 is broader. 



The male bears a superficial resemblance to the same sex of 

 T. betulce from Europe, but it is much larger and the tails are 

 longer and more slender.
