II.— THE NOTODONTINA. 57 



This interesting genus is relatively far more numerous in New Zealand than 

 elsewhere, its place in other regions being largely taken by Hydriomena. We have 

 no less than thirty-one known species, and many others will no doubt be ultimately 

 discovered, especially in the mountainous districts of the west coast of the South 

 Island. 



XANTHORHOE LIMONODES, Me.yr. 



(Epyaxa limonodes, Meyr., Trans. N. Z. Inst. xx. 5-i.) 



(Plate VII., fig. 46 $ .) 



This species has occurred at Wellington and at Cape Terawhiti in the North 

 Island. 



The expansion of the wings is about 1 inch. The fore-wings of the male are dull olive- 

 green with numerous, rather obscure, wavy brownish transverse lines; these lines are all more 

 distinct near the casta : there are two transverse rows of white dots near tlie base, a very broken 

 line of white dots at about three-fourths, one of the dots forming a crescentie marl,- above the 

 middle; beyond this line the colour is often paler, especially towards the apex, but inside this 

 line there is often a considerably darker patch ; there is a very distinct blackish patch just 

 below the apex. The apex of the wing slightly projects, and the termen is arched. The hind- 

 wings are very pale greenish-ochreous ; there is an obscure dusky transverse line in the middle. 

 The female has the fore-wings much browner; there arc several additional rows of white dots 

 and two conspicuous white spots above the middle. 



The species is rather variable. In many specimens the dorsal half of the fore- 

 wing is much paler than the costal half. 



The perfect insect appears from November till March, and frequents dense forest. 

 It is not a common species. 



XANTHORHOE SUBDUCTATA, Walk. 

 (Larentia subductata, Walk. 1198. Epyaxa subductata, Meyr., Trans. N. Z. Inst. xx. 55.) 

 This species has occurred at Auckland. 



" The expansion of the w'ings of the female is 26 mm. (about 1 inch). Head, palpi, and 

 thorax pale greyish-ochreous, somewhat mixed with yellow-greenish, and densely irrorated with 

 fuscous. Antennae whitish-ochreous annulated with fuscous. Abdomen grey-whitish, densely 

 irrorated with fuscous. Legs dark fuscous, apex of joints ochreous- whitish, middle and posterior 

 pair irrorated with grey-whitish. Fore-wings with costa gently arched, termen waved, slightly 

 rounded, oblique; pale greyish-ochreous, mixed with yellow-greenish, and thinly sprinkled with 

 fuscous, tending to form faint waved lines ; three light fuscous fasciae, each marked with three 

 dark fuscous lines ; first near base, outer edge sharply angulated above middle ; second from two- 

 fifths of costa to before middle of dorsum, slightly curved; third from two-thirds of costa to two- 

 thirds of dorsum, outer edge somewhat prominent in middle, rather sinuate above it ; a crescentie 

 black obscurely whitish-margined discal spot; a short oblique cloudy fuscous streak from ape> ; 

 cilia light fuscous, somewhat sprinkled with whitish. Hind-wings light grey ; a grey discal 

 dot before middle; a median band of three darker lines, outer rather prominent in middle; faint 

 indications of other darker lines, most distinct posteriorly; cilia grey- whitish, with two cloudy 

 grey lines." — (Meyrick.) 



The perfect insect appears in December. 



XANTHORHOE ROSEARIA, Dbld. 



{Cidaria rosearia, Dbld., Dieff. N. Z. ii. '285, Butl., Cat. pi. iii. 13. Corcmia ardularia, Gn., E. M. M. v. 63. 



Coremia inamanaria, Gn., E. M. M. v. 63. Epyaxa rosearia, Meyr., Trans. N. Z. Inst. xvi. 71.) 



(Plate AIT., fig. 22 $, 23?.) 

 This species has occurred at Wellington in the North Island; and in the South 

 Island at Akaroa, Christchurcb, and Dunedin.
