 NEW ZEALAND. 



BT G. T. HUDSON, T.E.S., F. X.Z.INST. 



Ichneutica nervosa, sp. n. 



This verv striking insect was discovered by Mr. F. S. Oliver on 

 Bold Peak, Lake Wakatipu, in December 1910. 



The expansion of the -wings of the male is almost IJ inches. The fore- 

 wings have the costa almost straight, the apex rather acute and the termen 

 obliquely rounded ; briffht ochreons xcith the veins heavily marhed in clear white 

 and icith black marJcings between the veins ; a small black spot at the base ; an 

 elongate blotch between vein 1 and the dorsum ; two elongate marks between 

 veins 1 and 2; wedge-shaped marks at the origins of veins 2, 3, 4, and 5; a 

 large blotch between veins 5 and 6 ; a much smaller blotch between veins 

 6 and 7; two obscure elongate marks in disc immediately below middle of 

 costa and two obscure blackish lines between the costal and subcostal veins ; 

 a curved series of subterminal spots and a series of elongate terminal marks. 

 The hind-wings are greyish-brown. The cilia of all the wings are whitish- 

 ochreous. The head is pale brownish-ochreous. The thorax is densely 

 clothed with brownish-ochreous hair with a brown horseshoe-like mark in the 

 middle. The abdomen is pale ochreous. The antennae, which are heavily 

 bipectinated throughout, are reddish-ochreoiis. 



Mr. Oliver very kindly submitted his unique specimen to me for 

 description. It was captured on the mountain, at niglit. 



Tatosoma nigra, sp. n. 

 A single specimen of this insect was captured in forest at Whaka- 

 papa, on the lower slopes of Mount Euapehu, at an elevation of about 

 4000 feet above the sea-level. 



The expansion of the wings of the female is 1|- inches. The palpi are 

 blackish, scarcely longer than the xcidth of the head. The antennae are blackish 

 with the apical portions dull ochreous. The head and thorax are dull 

 greenish-ochreous. The fore-wings are rather broad with the termen oblique, 

 bowed outwards near the middle; there is a small dull greenish-ochreous 

 basal patch, bisected by a broken black transverse line ; the sub-basal area is 

 black with a very few scattered white and dull reddish scales ; the inner edge of 

 the median band is bounded by a strongly dentate white line with a very deep 

 dentation just before the doi'sum ; its outer edge by a less dentate white line 

 with a decided projection below the costa; within the median band there are 

 three distinct wavy black transverse lines, the intervening spaces being dark 

 grey, the costal, discal, and dorsal portions of the median baud have a few 

 scattered dull green and reddish scales ; the termiiial and subteinninal areas are 

 almost black with scattered dull green, whitish, and dull reddish scales, these 

 are thickest on the terminal area ; there is a series of black terminal dots 

 arranged in pairs ; on the dorsum the spaces between all the black transverse 

 lines are stronglv marked in white and the main veins are more or less strongly
