‘‘This appears to be a good species allied to X. came- 
lias, but with the costa of fore-wings less arched posteriorly, 
and posterior edge of median band practically straight, 
not bent near costa; also much darker in general colouring. 
I have not yet seen any specimen except the original type.’’ 
Mr. Prout considers that the specimen referred to is 
nothing but a large dark form of Asaphodes rufescens. 
XANTHORHOE CAMELIAS. 
(Larentia camelias, Meyr., Trans. N.Z. Inst. xx., 58.) 
(Plate XIII., fig. 12 @, 18 @.) 
This very local species was discovered by Mr. Mey- 
rick in the North Island at Whangarei, and has since been 
found at Waimarino and Taihape. In the South Island 
it has occurred at Otira and at Wallacetown, near Inver- 
eargill. 
The expansion of the wings of the male is 14 inches; of the 
female about 1 inch, The fore-wings, which have the costa 
strongly arched before the apex and the termen deeply indented 
below the apex, are rather dark ochreous-grey, strongly tinged 
with reddish-brown in the female; the basal patch and median 
band are margined with very broken wavy whitish lines; the 
apical portion of the outermost line forming two conspicuous 
crescentic marks; inside the median band there are several 
wavy brownish lines and a conspicuous discal dot; outside a 
series of brownish subterminal spots. The hind-wings are pale 
ochreous, with several grey transverse lines, darker on the 
dorsum, and a rather conspicuous discal dot. 
The perfect insect appears in December and January, 
and frequents forest. It is evidently extremely local, 
although fairly common where found. 
XANTHORHOE CHIONOGRAMMA. 
(Larentia chionogramma, Meyr., Trans. N.Z. Inst. xvi., 82.) 
(Plate XIII., fig. 44 @, 43 9.) 
This very dull-looking species has occurred on Mount 
Egmont in the North Island. In the South Island it has 
been found on Mount Arthur, Mount Hutt, at Otira and 
Lake Wakatipu. 
The expansion of the wings of the male is 14 inches; of 
the female 14 inches. The fore-wings are rather dark greyish- 
brown; there are numerous indistinct wavy paler and darker 
transverse lines near the base; a broad dark brown median band 
paler in the middle, containing a minute blackish discal dot, 
and edged with an interrupted jagged white line towards the 
termen; there are several broken darker and paler lines on the 
subterminal area. The hind-wings are very pale greyish- 
ochreous, clouded with grey near the base, and with several 
rows of small cloudy grey spots near the termen. The female is 
paler than the male and the markings are less distinct. 
The perfect insect appears in December and January, 
and frequents wooded valleys on the lower slopes of the 
mountains, at elevations of from 2,000 to 3,000 feet. 
XANTHORHOE CHLOROCAPNA. 
(Xanthorhoe chlorocapna, Meyr., Records of Canterbury Museum, 
di, (D215) 
(Plate XIV., fig. 11 4.) 
This very striking species was discovered by Mr. C. 
Lindsay, at Mangere, Chatham Islands, 

X.—THE GEOMETRIDAE. 
The expansion of the wings is slightly under 1 inch. The 
fore-wings, which have the costa strongly arched before apex, 
and the termen slightly outwards-bowed near middle, are deep 
sooty-brown; the costal region is clouded with brownish-ochreous 
towards base, where there are traces of several transverse lines; 
a conspicuous brownish-ochreous mark on costa at 3, continued 
as a broken line almost across the wing, and indicating the 
outer edge of the median band. The hind-wings are deep sooty- 
brown, without markings. All the cilia are warm brownish- 
ochreous. 
The perfect insect appears in January. 
Described and figured from specimens kindly given to 
me by Professor Speight, Canterbury Museum. 
XANTHORHOE CEDRINODES. 
(Xanthorhoe cedrinodes, Meyr., Trans. N.Z. Inst. xliii., 72; X. 
undulata, Philp., Trans. N.Z. Inst. xlv., 76.) 
(Plate XIII., figs. 27, 28 @, varieties.) 
This rather large and conspicuous insect was dis- 
covered on the Mount Arthur Tableland, at an altitude of 
about 4,000 feet above the sea-level. It has also occurred 
on Mount Ruapehu and at Dunedin, Invereargill and 
Stewart Island. 
The expansion of the wings is from 1} to almost 14 inches. 
The fore-wings, which have the costa almost straight, the apex 
rather acute and the termen strongly scalloped, are dull pinkish- 
ochreous with the basal patch and median band dull pinkish- 
brown; the inner edge of the median band is concave and 
strongly waved, the outer edge has a curved indentation above 
the middle and two rounded projections below the middle, in 
addition there are other slighter irregularities; the basal patch 
and median band are both traversed by numerous fine wavy 
blackish transverse lines and the intervening spaces with fine 
whitish-ochreous lines; all the veins are strongly marked with 
black and white dots. The hind-wings are pale dull pinkish- 
ochreous, with numerous fine wavy grey transverse lines strong- 
est near the dorsum, but obsolescent beyond the middle; the 
termen is strongly scalloped. All the wings have a terminal 
series of black marks and the cilia are dull pinkish-grey. In 
the female the median band is very faint, and the general colour- 
ing duller and much more uniform than in the male. 
Both sexes vary considerably in the intensity of the 
markings and in the general brightness of the colouring. 
A rather smaller and much brighter form (fig. 27) 
occurs around Dunedin, in which the ground colour of the 
fore-wings is yellowish-brown and the basal patch and 
median band rich chocolate brown. Another form (X. 
undulata, Philp.) has the principal veins on the outer por- 
tions of the median band sharply marked in black, the 
rest of the markings being more indistinct than usual. As 
already stated, this insect has often been confused with 
Hydriomena prionota from which, however, it may be 
immediately distinguished by its larger size and the pecti- 
nated antennae of the male. 
The perfect insect appears from September till Feb- 
ruary, and is attracted by blossoms. It is usually found 
amongst open scrub composed of Manuka, Dracophyllum 
and other shrubs,
