lata. We are indebted to Mr. Philpott for apprehending 
the differences between this species and 7. tipulata. 
TATOSOMA MONOVIRIDISATA. 
(Tatosoma monoviridisata, Clarke, Trans. N.Z. Inst., lii., 35.) 
(Plate XLIX., figs. 6 @,7 9.) 
This very beautiful species was discovered by Mr. C. 
E. Clarke at Waitati, near Dunedin. 
The expansion of the wings of the male is 14 inches; of 
the female slightly over 12% inches. It differs from Tatosoma 
tipulata in having the ground colour of a much deeper and 
richer green; the transverse markings very nwuch less distinct 
and very deep green in place of black; the palpi distinctly 
longer in the male; the hind-wings greyish-ochreous strongly 
tinged with green especially on the termen and the anal lobe of 
the male smaller. 
The perfect insect appears in November, 
beaten from Coriaria. 
I am indebted to Mr. Clarke for the opportunity of 
figuring both sexes of this fine insect.

TATOSOMA TRANSITARIA. 
(Tatosoma transitaria, Walk., Cat., xxv., 1419; Meyr., Trans. N.Z. 
INSts Satie ok.) 
This species is stated to be somewhat smaller than 
either 7. tipulata or T. agrionata with the fore-wings 
duller, more grey-green, striae more obscure, with a charac- 
teristic distinct cloudy small whitish spot at lower 
extremity of transverse vein, hind-wings smaller, rather 
dark grey, lobe in male hardic larger than in 7. BE 
I am unacquainted with this insect. 
TATOSOMA ALTA. 
(Tatosoma alta Philp., Trans. N.Z. Inst., xlv., 76.) 
(Plater eS iss Alar dao) 
This very pretty little species has occurred in the 
South Island at Otira, on Bold Peak, Lake Wakatipu, and 
on The Hump, Southland. 
The expansion of the wings of the male is slightly over 1 
inch, of the female fully 14 inches The fore-wings, which have 
the termen slightly bowed near the middle, are whitish with 
numerous very faint wavy greenish transverse lines; there are 
several interrupted blackish transverse lines near the base; a 
distinct median band, furcate on costa and dorsum, composed of 
fine wavy blackish transverse lines and sprinkled with reddish 
scales; a subterminal Series of small blackish blotches and a 
terminal series of minute double dots. The hind-wings are 
greyish-ochreous, darker towards the termen, with a large 
elongate lobe in the male. 
Appears to vary considerably in the general intensity 
of the markings and in the extent of the reddish irroration. 
In some specimens the discal and terminal areas of the 
fore-wings have purplish reflections. 
The perfect insect appears in November and Decem- 
ber, and inhabits sub-alpine forests, from about 1,500 to 
4,000 feet above the sea-level. It is attracted by light. 
This species is somewhat similar to T'atosoma fasciata 
from which, however, it may be easily separated by its 
much shorter palpi, straighter termen and larger lobe in 
the male. 
TATOSOMA APICIPALLIDA. 
(Tatosoma apicipallida, Prout., Trans. N.Z. Inst., xlvi., 122.) 
(Plate XLIV., figs. 28 @, 29 9.) 
This species was discovered by Mr. W. G. Howes on 
Ben Lomond, Lake Wakatipu. It has also occurred on 
the Humboldt Range in the same district and more recently 
on Mount Ruapehu, in the North Island. 
The expansion of the wings is 1} inches. Very closely allied 
to T. alta from which it differs in its slightly larger size, darker 
colouring, greyer hind-wings, shorter abdomen of the male and 
distinct pale apical patch. The fore-wings in both sexes are 
suffused with iridescent pinkish reflections not present in T. 
alta and the fine wavy transverse lines are less confined to the 
sub-basal, median and subterminal areas of the fore-wings. 
The perfect insect appears in November and Decem- 
ber, and may be looked for in sub-alpine forests. 
TATOSOMA FASCIATA. : 
(Tatosoma fasciata, Philp., Trans. N.Z. Inst., xlvi., 118.) 
(Plate XLIV; fig: 31 47 Plate X11, fig: 1) 9") 
This very interesting species was discovered by Mr. 
M. O. Pasco at Lake McKenzie. It has also occurred on 
Mount Arthur and the Hunter Mountains, at elevations of 
3,500 feet. 
The expansion of the wings is about lfinches. The palpi are 
very long; in the female nearly half the length of the antennae, 
in the male one-third shorter than in the female. The fore-wings 
are rather broad, with the costa strongly arched at the base and 
the termen bent outwards below the apex, greyish-green in the 
male, white in the female, with blackish and _ orange-yellow 
markings; there is a fine irregular black line near the base, its 
extremity produced shortly along the dorsum; a rather broad 
sub-basal band thickly strewn with orange-yellow and blackish 
scales; a broad doubly curved blackish median band, fainter near 
the middle, especially on the costa, with its edges obscurely 
marked with broken orange-yellow lines; there are two inter- 
rupted subterminal lines composed of orange-yellow and greyish 
scales; a terminal shading: of the same and a terminal series of 
double blackish dots; the veins are marked with orange-yellow. 
The hind-wings are white with two very faint greyish transverse 
bands. The cilia of all the wings are grey-whitish. 
The perfect insect appears in November and Decem- 
ber. It seems to be an extremely rare and local species, 
confined to mountainous districts in the South Island. 
Deseribed and figured from specimens kindly fur- 
nished by the late Mr. Pasco.
