290 EUPHYIA. By L. B. Prout. 



somewhat diffuse iJostmedian. paler outside it. New Zealand, local and rarely common: Wellington (type), 

 Artliur's Pass. Mount Cleughearn, Queenstown, etc. Aceording to Philpott very abundant in the Hunter 

 Mountains. 



canescens. E. canescens PhiJpott (2Si). Ciliation of the ^ antenna 1. Philpott considers it near hemizona but 



with "the giound-colour wliolly different and niany other distinction.s". Actually it is much more Horisme-like, 

 especially in the well-marked upperside of the hindwing, and though the body is not ajjpreciably crested it is 

 quite iJossible 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. 9 smaller and still nioie niarked with finer 

 lines than the ^. Queenstown. New Zealand. 



arida. E. arida Btlr. (28 k). Very striking in its typical form, in which the forewing is very broadly dark cin- 



namon ("sayal-brown" of Ridgway) 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. 

 chaelka. — ab. chaetica Mtijr. has the median area also blackish, Init retains the costal marks. Meyhick mentions this 

 form first, so I select it as his type and utilize the name. — Distributed in 8outh Island and to Stewart Island; 

 type from Otago. 



harmonica. E. harmotlica CJrtrkr (28 k). Only known to nie from the description and Hüd.son's figure; perhaps a 



colour-form of the following, Init Clarke claims it for a species because the "eyanism" suggests a tropical line 

 of ance.strv and the coloration. which in rnUkhlora is strongly cryptic, is here apo.sematic. "Pale cerulean blue" 

 with the i3rinci])al light markings changed to bright orange. A ,^ from Waitati Bush, near Dunedin. 



callichlora. E. callichlora Biitl. (28 k). This .species and tlie two whicli follow are sufficiently characterized by the 



bright green scaling of the forewing. The thorax is rather well crested posteriorly and the J abdomen tufted 

 laterally. In caHicMora the foreA\dng is not very strongly variegated, the median band rarely much darkened 

 except at its edges, of wJiicli 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. 



praerupki. E. praerupta Philpott (28 k) "may be regarded as the mountain representative of callichlora", but its 



author has denionstrated 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 i^ostmedian bidentate prominence 

 is stronger and suffuses distally with a w e 1 1 - d e v e 1 o p e d p r e s u b t e r m i n a 1 b a n d; oblique 

 apical dash strong and cutting off a pale s u b t r i a n g u 1 a r a p i c a 1 p a t c h. Underside also rather 

 sharply marked, tiie apical region (at least in my example) \dth a rusty finge. Hunter Mountains: Mount 

 Cleughearn, type; also from Lake Howden. 



similala. E. siiTlilata Walk. (= timarata Feld.) (28 k). Very distinct in its red-brown suffusion on both surfaces 



(including most of the hindwing above, except costally), the po.steriorly 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 



nigrofascia- area wholly black: ab. nigrofasciata nov. — Larva on Coprosma, much less gay than that oi callichlora. darker 



'"■ and with mossy green dorsal ridges, so as to mimic mossy twigs of the foodplant. 



rixaia. E. rixata Feld. (28 k). Glossy, typically wdth nearly the coloration and aspect of Ecliptopera or L<nn- 



jiropteryx: quite unmistakable among New Zealand Euphyia. notAvithstanding its variability. As Philpott 

 says, it appears to beconie more duU 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. 

 squalUlü. Distributed in South Island, offen abundant. — ab. loc. squalida Bull . Very weakly nuxrked. tlie distal area 

 of the forewing sliowing little or no marking excepting the ajjical dash. Type from Otago Peninsula: commoner 

 Uara. at Invercargill. — liara subsp. nov. (28 1). Colouring much brighter, the band with more finge of purple, the 

 ground-coloin- paler and (especially on hindwing and underside) consideialily more ochreous-tinted. sometimes 

 recalling piirpnrifera. North Island: Auckland to Wellington; type from Titahi. in my collection. 



purpurifem. E. purpurifera Fereday (28 1). Probably related to ri.vata. 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 be common in wooded gullies; widely distributed in South Island, up to about 3000 feet ; also found 

 ochreifera. on Mount Egmont and at Ohakune. - ochreiiera suhsp. nov.. from the lower altitudes, at least about Dunedin. 

 has the hindwing above and the forewing beneath much more deeply suffused with ochreous than tlie typical 

 forms. Type in my collection.
