II. THE NOTODONTINA. 41 



PAEADETIS POEPHYEIAS, Meyr. 



(Parysatis porphyria-s, Meyr., Trans. N. Z. Inst. xvi. 58. Paradctis porphyrias, Meyr., ib. xviii. 184.) 



(Plate VI., fig. 36 f .) 



This interesting little insect has occurred in the South Island at Mount Arthur, 

 Castle Hill, the Otira Gorge, and Lake Wakatipu. 



The expansion of the wings is about f inch. The fore-wings of the male are deep purplish- 

 brown ; there is a wavy, reddish, transverse line at about one-third and another at about two- 

 thirds ; between these two lines near the dorsum there are often four, more or less distinct, yellow 

 dots ; there is an obscure orange mark at the origin of the first line and a conspicuous mark at the 

 origin of the second. The hind-wings are deep purplish-brown. The cilia of all the wings are white. 

 The fore-wing has the apex hooked and the termen deeply excavated above and below the middle. The 

 female is very much paler ; the lines are more distinct and the veins are marked in brown. 



The perfect insect appears in January. It frequents rather open spots in the 

 forest, and flies in a very busy manner close to the ground amongst the numerous 

 ferns and other plants, which are always abundant in such situations. It is con- 

 sequently very inconspicuous and sometimes difficult to capture. Thus, no doubt, it 

 is often overlooked, and perhaps is much commoner than at present appears probable. 



Genus 3. CHLOEOCLYSTIS, Hb. 



" Face with short cone of scales. Palpi rough-scaled. Antennae in male shortly ciliated. 

 Abdomen crested. Fore-wings with areole simple, vein 11 running into or anastomosing with 12. 

 Hind-wings with vein 8 anastomosing with cell from near base to beyond middle." (Plate II., 

 figs. 19 and 20.) 



" This genus is especially characteristic of New Zealand, and is also found in 

 South Asia, a few stragglers occurring in Europe and elsewhere." (Meyrick.) 



We have twelve species, several of which are very beautiful. 



CHLOEOCLYSTIS PLINTHINA, Meyr. 



(Pasiphila plinthina, Meyr., Trans. N. Z. Inst. xx. 49.) 



(Plate VI., fig. 8.) 



This pretty species has occurred at Wellington. 



The expansion of the wings is about inch. All the wings are traversed by numerous obscure, 

 wavy, reddish-yellow lines ; the fore-wings have a dark shading near the base, a very large ichite 

 blotch in the middle, and a dark chocolate-brown patch near the apex. The hind-wings have 

 a large shaded white patch in the middle, a blackish dot near the base, and a series of brownish 

 crescentic marks on the termen ; the cilia of all the wings are pale brown barred with brownish- 

 black. The termen of the fore-wings is very oblique, of the hind-wings rather irregular. 



Many specimens of this insect are strongly tinged with green, and the shape and 

 size of the white patches on the fore- and hind-wings are subject to slight variations. 



The perfect insect appears in November and December. It frequents brushwood, 

 where it may be occasionally taken at rest on tree-trunks but more often dislodged 

 from the foliage. It is not a very common species. 



CHLOEOCLYSTIS BILINEOLATA, Walk. 



(Eupithecia bilineolata, Walk. 1246. E. muscosata, ib. 1246. Scotosia humerata, ib. 1362. Eupithecia

(Plate VI., fig. 9 type, fig. 10 variety.) 



This beautiful little species is common, and generally distributed throughout the 

 country.
