II.— THE NOTODONTINA. 51 



transverse line near the base, and a very broad central hand with a prominent projection somewhat 

 below the middle, almost touching the termen ; there is a brown dot above the middle of the wing and 

 numerous fine brown wavy lines in the central band ; the veins are marked in white near the termen. 

 The hind-wings are pale ochreous, with a few very faint transverse marks near the dorsum. The 

 termen of the fore-wings is slightly bowed in the middle. 



The perfect insect appears in January and February, and frequents forest, some- 

 times being found as high as 2,600 feet above the sea-level. Described and figured 

 from a specimen in Mr. Fereday's collection. 



HYDKIOMENA SIEIA, Meyr. 

 (Cephalissa siria, Meyr., Trans. N. Z. Inst. xvi. 93.) 

 (Plate VI., fig. 48.) 

 This odd little species was discovered by Professor Hutton at Dunedin. 

 The expansion of the wings is jj inch. The fore-wings are rich brown with two transverse hands 

 of darker brown ; the first near the base, rather narrow; the second near the middle, considerably 

 broader, especially on the costa. The hind-wings are bright orange. The termen of the fore-wings 

 is slightly excavated below the apex, and considerably bowed a little below the middle. 

 Described and figured from a specimen in Mr. Fereday's collection. 



Genus 7.— EUCHCECA, Hb. 



" Pace smooth, fiat. Antenna' in 3 shortly ciliated. Palpi short, slender, loosely scaled, 

 Fore-wings with areole simple. Hind-wings with vein 8 anastomosing with cell to beyond middle. 



"A small genus containing a, few species distributed throughout the northern 

 hemisphere and one Australian." — (Meyrick.) 



We have one species.

 Gn., E. M. M. v. 12. Asthena pulchraria, Butl., Cat. pi. iii. 18. Hippolyte rubropunctaria, Meyr., Trans.

(Plate VI., fig. 35.) 



This little species is common and generally distributed throughout both the North 

 and South Islands, and has also occurred at Stewart Island. 



The expansion of the wings is about § inch. AH the wings are pah- ochreous, with numerous 

 obscure reddish transverse lines. On the fore-wings there are four transverse series of black dots ; the 

 first near the base, the second a little before the middle, the third a little beyond the middle, and the 

 fourth on the termen ; between the second and third series of dots there is very frequently an elongate 

 blackish patch, especially towards the dorsum. The hind-wings have three series of black dots; the 

 first near the base, the second near the middle, and the third on the termen. The termen of both 

 fore- and hind-wings slightly projects near the middle. 



This species varies considerably in the extent of the blackish marking near the 

 middle of the fore-wings, as well as in the colour and intensity of the reddish transverse 

 lines. 



The larva is thus described by Mr. Fereday : * "The caterpillar has ten less, is cylindrical, rather 

 stout, with the segmental divisions incised ; its colour is pale dull green, sometimes suffused with 

 pink, brown, purple, or dark green; the dorsal line is purplish-brown, suffused, the central line 

 whitish; the spiracular line is whitish, broadly margined with purplish-brown; the segmental 

 divisions are pale yellowish-brown." 



The food is Haloragis alata, a common herbaceous plant growing in swampy 

 situations. The pupa is enclosed in a slight earth-covered cocoon.
