Epichorista emphanes Meyr., Trans. Ent. Soc. Lond. (1901), p. 571. E. theatralis Philp., Trans. N.Z. Inst., vol. 50, p. 128, 1918.
The acquirement of abundant material from the Mount Arthur tableland has shown me that the above correction is necessary. The female of emphanes is very variable, and the handsome theatralis is but one of the extreme forms.
Tortrix spatiosa n. sp.
♂ 27 mm. Head, palpi, and thorax purplish-brown tinged with grey, Antennae ochreous-brown, ciliations 1. Abdomen ochreous. Legs ochreous, anterior tarsi brown. Forewings moderate, fold extending to near middle of costa, costa oblique to middle, moderately arched, apex rectangular, termen subsinuate, rounded beneath, hardly oblique; purplish-brown, with ochreous suffusion; median band slightly darker, very obscure, broadly dilated on lower portion, anterior margin indented beneath costa; some whitish scales on costal edge at ½; a triangular area on costa before apex darker; terminal area ochreous: cilia bright ochreous. Hindwings whitish-grey obscurely mottled with darker: cilia whitish, tinged with ochreous round apex and termen.
♀ 28 mm. Head, palpi, and thorax pale purplish-brown tinged with pink. Abdomen pale ochreous. Legs ochreous. Forewings extremely strongly arched basally, slightly sinuate before apex, apex round-pointed, termen sinuate, not oblique, rounded beneath; ochreous, crossed with
numerous fine waved brownish lines; costa obscurely margined with silvery metallic scales; median fascia faintly indicated, running obliquely from costa before middle to before tornus, anterior margin indented beneath costa; a triangular purplish-brown blotch, thickly strewn with silvery metallic scales, on costa before apex: cilia ochreous, brownish at apex. Hindwings whitish, ochreous on apical ⅓: cilia whitish-ochreous, brownish round apex.
A very fine species. The male is very similar to some forms of T. excessana (Walk.), but is easily separated by the different costal contour of the forewing. The female is remarkable for the unusually strong basal arching of the forewing.
Mr. G. V. Hudson has examples of both sexes taken at Routeburn, Wakatipu, in February, 1911. I secured a very fine ♀ on the Dun Mountain in January, at an elevation of 2,500 ft. Holotype (♀) in coll. A. Philpott; allotype (♂) in coll. G. V. Hudson.
