by mo under the name of agrionata. These are now characterized below as 

 follows ; besides these, lestevata Walk., fimora Meyr., and topia Philp. are 

 good species, making six altogether. 



Tatosoma agrionata Walk. 



Cidaria agrionata Walk., Cat., p. 1417. C. indinataria, ih., p. 1418. 

 Sauris mistata Feld,, Reis. Nov., pi. 131, p. 12. 



This and the next species are extremely similar in colour and markings, 

 but in agrionata, the black markings on the striae of forewings are more 

 strongly developed, especially on the subterminal line, where they form 

 strong dashes, and above dorsum towards base ; the forewings are also 

 somewhat less elongate ; an immediate distinction is furnished by the 

 lobe of the hindwings in ,^, which is nearly twice as large as in tipulata, 

 reaching from the base to nearly the middle of the wing in length. 



I have this species from Christchurch, and Mr. Philpott sends it from 

 Wallacetown. 



Tatosoma tipulata Walk. 



Cidaria tipulata Walk., Cat., p. 1417. C. collectaria, ih., p. 1419. 

 Tatosoma agrionata. Huds., N.Z. Moths, 40, pi. 6, pp. 26, 27. 



Forewings more elongate than in agrionata, less marked with black ; 

 hindwings in cj with lobe not exceeding ^ of hindwings in length ; abdo- 

 men of cJ more elongate than in agrionata, but less so than in timora. 



I have examples from Wellington and Nelson, and Mr. Philpott sends it 

 also from Wallacetown. 



Tatosoma transitaria Walk. 



Cidaria transitaria Walk., Cat., p. 1419. 



This is a distinct species, of which both sexes are represented in the 

 British Museum collection, but otherwise not known to me ; somewhat 

 smaller than the two preceding, forewings duller, more grey-green, striae 

 more obscure, with a characteristic distinct cloudy small whitish spot at 

 lower extremity of transverse vein, hindwings smaller, rather dark grey, 

 lobe in 5* hardly larger than in tipulata. 



Hydriomena lithurga n. sp. 



cJ. 25 mm. Head and thorax pale greyish-ochreous mixed with whitish, 

 transversely barred with blackish-grey suffusion. Palpi 1^, blackish-grey, 

 lower longitudinal half whitish. Antennae somewhat stout, shortly 

 ciliated {\). Abdomen pale greyish-ochreous, mixed on sides with dark grey 

 and whitish, segmental margins white preceded by a black mark on each 

 side of back. Forewings triangular, costa rather strongly arched towards 

 apex, apex obtuse, termen rather obliquely rounded, crenate ; pale greyish- 

 ochreous, marked with indistinct waved striae of grey irroration becoming 

 blackish on costa ; margin of a small basal patch indicated on lower half 

 by a blackish stria edged with white posteriorly ; median band formed by 

 two fasciae of several rather irregular suffused grey striae each, well marked 

 except beneath costa, margins marked with black edged exteriorly with 

 white except near costa, anterior margin twice sinuate, posterior with median 

 third forming a rather strong subtriangular obliquely bilobate prominence ; 

 a transverse-linear black slightly whitish-edged diseal dot on anterior of 

 these fasciae ; subterminal line of ground-colour, slender, strongly waved,
