 32. Elach. melanura, n. sp. 



S. 13mm. Head, palpi, antennae, and thorax whitish- 

 grey. Abdomen ochreous-whitish, with a dense black apical 

 exsertible tuft. Legs dark fuscous, posterior pair ochreous- 

 whitish. Forewings lanceolate ; whitish-grey, somewhat irro- 

 rated with darker ; an elongate black dot on fold before 

 middle, a second in disc above middle, and a thhd in disc at 

 f : cilia grey-whitish, with a spot of black scales at base round 

 apex, and tips sprinkled with black. Hindwings and cilia pale 

 whitish-grey. 



Hamilton ; one specimen in January. I have two speci- 

 mens from Australia which closely resemble this, and which 

 agree in possessing the characteristic and highly peculiar 

 black anal tuft; but, as they differ considerably from the New 

 Zealand specimen, and also from one another, in the position 

 of the black dots on the forewings, I have not felt justified at 

 present in uniting them, although I think it very probable 

 that a longer series of specimens may prove this character to 

 be variable. 



33. Elach. gerasmia, n. sp. 



<? ? . 9-14mm. Head whitish. Palpi grey, terminal 

 joint and apex of second white. Antennae grey. Thorax 

 whitish-grey. Abdomen grey-whitish, anal tuft in male more 

 or less ochreous-tinged. Legs dark grey, posterior pair grey- 

 whitish. Forewings lanceolate ; light grey or rarely gi'ey- 

 whitish ; a black dot on fold in middle, and an elongate black 

 dot in disc at f : cilia grey, with indications of two black 

 lines for a short distance below apex. Hindwings and cilia 

 gi-ey. 



Hamilton, Makatoku, and Invercargill ; common in 

 swampy places, in December, January, and March.
