XANTHORHOE BEATA, Butl. 

 (Ciclana beata, Butl., Proc. Zool. Soc. Lond., 1877, 397, pi. xliii. 6. Larentia beata, Meyr., Trans. 



N. Z. Inst. xvi. 79.) 

 (Date VII., fig. 35 3 , 36 2 .) 



This very beautiful species has occurred at Wellington in the North Island, is 

 common and generally distributed throughout the South Island, and has also been found 

 at Stewart Island. 



The expansion of the wings is about 1 inch. The fore-wings are bright green ; there is a darker 

 area at the base edged with a jagged white line; then a paler band followed by a very broad darker 

 green central band edged with very jagged white line*, and containing several white patches in the 

 middle, one of which is situated close to the costa and encloses a Hack dot; beyond this central band 

 there is a paler area, then an interrupted darker green band edged with white ton-arch the termen. 

 There is an oblique pale mark from the apex of the wing. The hind-wings are very pale oehreous, 

 sometimes slightly tinged with green ; there are several obscure rows of dusky spots. 



The white markings included in the central baud are rather variable. 



The egg is smooth, oval, and pale green in colour. 



The young larva is orange-brown, becoming greenish-brown soon after emergence. The full- 

 grown larva is dark brown above and pale brown beneath, the two colours being sharply separated on 

 the sides by a broken white line. A series of V-shaped markings is situated on the back, each mark 

 enclosing a paler area. Several fine black wavy lines traverse the darker portions of the larva, ami a 

 dark mark, edged with black beneath, is situated on each segment just above the ventral surface. 



The food-plant is watercress. 



The pupa is enclosed in a frail cocoon on the surface of the ground. 



The perfect insect appears from October till March, and frequents forest. It is often 

 dislodged from dense undergrowth during the daytime, and may be found in the evening 

 on the blossoms of the white rata. It is very much commoner in some years than in 

 others; hut occasionally several seasons will pass without our noticing a single specimen 

 of this attractive insect. The colouring is extremely protective when the moth is resting 

 on moss-covered tree trunks. 



XANTHOEHOE ADONIS, n. sp. 

 (Plate VII., fig. 49 3 .) 



This extremely beautiful insect has occurred in the South Island at Castle Hill, and 

 at Lake Wakatipu. 



The expansion of the wings is 1 inch. The fore-wings are vivid green : there is a broad, wavy, 

 black transverse line near the base ; a somewhat broken line at about one-third, much broader on the 

 costa and edged with white towards the base; a very conspicuous lima// black line at two-thirds, shaded 

 towards the base, and sharply edged with white towards flic termen ; between this line and the termen 

 there are several black marks, forming another extremely broken transverse line. The hind-wings arc 

 pale orange-brown, with a faint grey central band. 



The perfect insect appears in January. It frequents forests at elevations of from 

 1,000 to 2,000 feet above the sea-level, but it is not common. 



Mr. Meyrick regards this insect as identical with Xaiithorliue beata. 



XANTHORHOE CHLOIOAS, Meyr. 



(Larentia chlorias, Meyr., Trans. N. Z. Inst. xvi. 80.) 



This species was discovered in the South Island at Castle Hill, by Mr. Meyrick. 



"The expansion of the wings of the male is :!() mm. (about 1} inches). Fore-wings moderate, termen 



hardly rounded; bright yellow; base of costa dark fuscous-purple ; a curved row of three very small 



dark purple-fuscous spots about one-fourth, and another of four spots before middle, costal spots larger; a
