Lythria siris, n. sp. Plate XV, fig. 1. 



This very neatly marked little species was discovered by 

 Mr. J. H. Lewis on the Old Man Range, Central Otago, at an 

 elevation of about 4,000 ft. 



The expansion of the wings is a little over § in. The fore- 

 wings are slaty-grey, with light reddish-brown, black, and pale- 

 yellowish markings ; there is a very small grey area at the base, 

 followed by a wavy transverse reddish-brown band ; next two 

 yellowish- white bands enclosing a very narrow yellowish-brown 

 area ; then a strongly waved whitish line, followed by a narrow 

 black line and a broad reddish-brown line ; the central area is 

 broad, slaty - grey, with a reddish-brown discal dot ; this is 

 followed by an extremely sharply angulated series of lines, 

 consisting of a narrow reddish-brown line, a narrow black line, 

 a narrow yellowish-white line, and a shaded orange-brown line ; 

 the termen is shaded with dark-brown with a very fine, wavy, 

 whitish line and a series of small reddish-brown spots. The 

 hindwings are golden-yellow, the basal and terminal portions 

 broadly clouded with black, and a very wavy central black 

 line. The cilia of all the wings are brownish-grey. The female 

 is paler, and much less distinctly marked than the male. 



The perfect insect appears in February.

In January, 1905, I captured two specimens of this very 

 distinct species on the Humboldt Range, at the head of Lake 

 Wakatipu, at an elevation of about 4,500 ft. above the sea- 

 level. 



The expansion of the wings of the male is nearly If in. ; of 

 the female, 1^ in. The fore wings of the male are very dark 

 greyish-black, speckled with paler grey ; there are several small 

 black marks on the veins, and an obscure yellowish-brown 

 transverse line at about § ; the hindwings are dark-grey, 

 speckled with paler grey ; the cilia of all the wings are pale 

 greyish-white, strongly barred with blackish-grey. The body is 

 black ; the head and thorax are densely clothed with long black 

 hair ; the antennae are heavily bipectinated. The female is 

 much paler, with numerous obscure blackish transverse lines on 

 both fore and hind wings ; the forewings are faintly clouded 

 with yellowish-brown towards the base and termen, and all the 

 wings have a terminal row of small but conspicuous oblong 

 black marks. The antenna- arc simple, and the head and 

 thorax are moderately clothed with short black hairs. 



This species may be at once distinguished from any of the 

 varieties of Dasyuris hectori by the hairy clothing of the head 

 and thorax, and the strongly bipectinated antenna' of the male.
