somewhat, diffuse postmedian, paler outside it. New Zealand, local and rarely common: Wellington (type), 
Arthur’s Pass, Mount. Cleughearn, Queenstown, etc. According to Philpott very abundant in the Hunter 
Mountains. 
E. canescens Philpott (28 i). Ciliation of the $ antenna 1. Philpott considers it near hemizona but 
with “the ground-colour wholly different and many other distinctions”. Actually it is much more Horisme- like, 
especially in the well-marked upperside of the hindwing, and though the body is not appreciably crested it is 
quite possible that it may, like the Palaearctic desiderata Stgr. (see Suppl.-Vol. 4, p. 251), have to be trans¬ 
ferred to that genus or its vicinity; veins interruptedly blackish. $ smaller and still more marked with finer 
lines than the <$. Queenstown, New' Zealand. 
E. arida Btlr. (28 k). Very striking in its typical form, in which the fore wing is very broadly dark cin¬ 
namon (“sayal-brown” of Bidgway) medially, very dark slate-violet proximally and terminally; costa outside, 
the postmedian with 2 thick curved pale lines, outside the proximal with a similar pair sometimes less distinct. 
ah. chaetica Meyr. has the median area also blackish, but retains the costal marks. Meyrick mentions this 
form first, so I select it as his type and utilize the name. — Distributed in South Island and to Stewart Island; 
type from Otago. 
E. harmonica Clarke (28 k). Only known to me from the description and Hudson's figure; perhaps a 
colour-form of the following, but. Clarke claims it for a species because the “cyanism” suggests a tropical line 
of ancestry and the coloration, which in callichlora is strongly cryptic, is here aposematic. “Pale cerulean blue” 
with the principal light markings changed to bright, orange. A $ from Waitati Bush, near Dunedin. 
E. callichlora Bull. (28 k). This species and the tw'o which follow' are sufficiently characterized by the 
bright green scaling of the forewing. The thorax is rather well crested posteriorly and the $ abdomen tufted 
laterally. In callichlora the forewing is not very strongly variegated, the median band rarely much darkened 
except at its edges, of which the proximal is strongly indented at both folds (the anterior indentation deep), 
the distal moderately bilobed in the middle. Ground-colour of hindwing and underside predominantly whitish, 
suffused and marked with grey. Distributed in New Zealand at least from Cape Egmont to Invercargill. Larva 
on Coprosma rotundifolia; moderately slender, slightly flattened, very bright green dorsally, with a conspicuous 
crimson lateral line, sometimes edged with white. Pupa in a. fragile cocoon among leaves. 
E. praerupta Philpott (28 k) “may be regarded as the mountain representative of callichlora” , but its 
author has demonstrated a difference in the genitalia. On the whole more strongly marked; the antemedian of 
the forewing in my only specimen (here figured) is less oblique at the costa, the postmedian bidentate prominence 
is stronger and suffuses distally with a w e 11 - d e v e 1 o p e d presubterminal band: oblique 
apical dash strong and cutting off a pale subtriangular apical patch. Underside also rather 
sharply marked, the apical region (at. least in my example) with a rusty tinge. Hunter Mountains: Mount 
Cleughearn, type; also from Lake Howden. 
E. similata Walk. (= timarata Feld.) (28 k). Very distinct in its red-brown suffusion on both surfaces 
(including most of the hindwing above, except costally), the posteriorly curved antemedian and the sharply 
white subterminal near the tornus. Widely distributed from Napier southward to Stewart Island; also on the 
Chatham Islands. — Philpott mentions occasional aberrations in the Invercargill district with the median 
area wholly black: ab. nigrofasciata nov. — Larva on Coprosma , much less gay than that of callichlora, darker 
and with mossy green dorsal ridges, so as to mimic mossy twigs of the foodplant. 
E. rixata Feld. (28 k). Glossy, typically with nearly the coloration and aspect, of Ecliptopera or Lam- 
propteryx; quite unmistakable among New Zealand Euphyia, notwithstanding its variability. As Philpott 
says, it appears to become more dull and suffused towards the souther limits of its distributional area. Fel¬ 
der’s type, not exactly localized, is only moderately dark, the subterminal spots of the forewing well developed. 
Distributed in South Island, often abundant. — ab. loc. squalida Butl. Very weakly marked, the distal area 
of the forewing showing little or no marking excepting the apical dash. Type from Otago Peninsula; commoner 
at Invercargill. — iiara subsp. nov. (28 1). Colouring much brighter, the band with more tinge of purple, the 
ground-colour paler and (especially on hindwing and underside) considerably more ochreous-tinted, sometimes 
recalling purpurifera. North Island: Auckland to Wellington; type from Titahi, in my collection. 
E. purpurifera Fereday (28 1). Probably related to rixata, but still more striking in the shape of the 
markings and more brightly and contrastingly coloured. Founded on specimens from Mount Hutt, where it 
is said to he common in wooded gullies; widely distributed in South Island, up to about 3000 feet; also found 
on Mount Egmont and at Ohakune. ochreifera subsp. nov., from the lower altitudes, at least about Dunedin, 
has the hindwing above and the forewing beneath much more deeply suffused with ochreous than the typical 
forms. Type in my collection.
