Metrick. — Description* of New Zealand Lepidoptera. 247 



I originally described the species, from a series taken by myself at Hamilton. 

 I treated a widely different female specimen with reddish-ochreous forewings 

 and whitish hind wings as being the other sex of the species ; after recon- 

 sideration of the specimens, all taken together in the same locality, this 

 still seems to me to be probably correct. I desire to direct the attention 

 of collectors to this peculiar case ; it ought not to be difficult to determine 

 whether the species has a dimorphic female (which would be unprecedented 

 in this group), or whether there is some error. 



EUCOSMIDAE. 



Spilonota dolopaea Meyr. 



Additional specimens sent by Mr. Hudson show that the male has a 

 long expansible blackish hair pencil from base lying in a dorsal fold of hind- 

 wings ; in the original example this was completely concealed and therefore 

 unfortunately overlooked, but in those now sent it is exposed and conspicuous, 

 constituting a very distinctive character. 



COSMOPTERYGIDAE . 



Recent study has led me to conclude that Batrachedra should properly 

 be included in this family instead of the Coleophoridae, which latter group 

 is therefore unrepresented in New Zealand. 



Batrachedra filicicola n. sp. 



o. 8 mm. Head and thorax bronzy-whitish. Palpi with appressed 

 scales, whitish, with faint greyish marks at apex of second joint, and base 

 and apex of terminal joint. Abdomen grey. Forewings narrow-lanceolate, 

 apex narrowly produced ; violet-grey, becoming darker posteriorly, produced 

 apex blackish : cilia grey, base round apical third of wing paler and 

 sprinkled with blackish, sometimes forming indistinct dots, at apex with a 

 short black subbasal bar. Hindwings violet-grey ; cilia grey. 



Karori, on tree-ferns, in November (Hudson) ; five specimens. Probably 

 the larva would feed on vegetable refuse accumulated on the stems. 



NEPTICULIDAE. 



Nepticula oriastra n. sp. 



?. 6 mm. Head, antennae, thorax, and abdomen ochreous- white. Fore- 

 wings lanceolate ; ochreous-white ; a small black dot on fold before -J of 

 wing ; apical third of wing blackish : cilia ochreous-white, base dark grey. 

 Hindwings and cilia whitish. 



Otira River, on scree east side of gorge at 3,000 ft., on underside °f 

 leaves of Celmisia, in January (Miss Stella Hudson) ; two specimens. A 

 very remarkable and interesting species : the minute insects of this genus 

 are difficult of observation, and the circumstances of discovery reflect great 

 credit on the entomological acumen of the fair captor. The larva probablv 

 mines in the leaves of the Celmisia.
