Comps. bifaciella, Walk. 

 (Geleckia bifaciella, Walk., 657.) 



Male, female. — 10-12 mm. Head and thorax shining 

 bronze. Palpi white, terminal joint dark fuscous. Antennas 

 black, with a white subapical band. Abdomen dark fuscous, 

 beneath white. Legs blackish, banded with white. Fore wings 

 elongate, narrow, posteriorly slightly dilated, costa almost 

 straight, apex obtuse, hindmargin obliquely rounded ; basal third 

 dark fuscous, with brassy reflections, towards costa purplish, 

 posterior two-thirds ferruginous-orange, witb a few dark fuscous 

 scales ; a shining violet-white black-margined oblique transverse 

 spot from costa at f , reaching nearly half across wing ; a strongly 

 inwards-curved pale violet-golden-metallic fascia from § of costa 

 to anal angle, sometimes obsolete on costa ; an outwards-curved 

 pale violet-golden-metallic fascia from a small snow-white spot 

 on costa at J to anal angle, where it meets first fascia ; both these 

 fasciae are broadest in disc, narrowed towards extremities : cilia 

 white, with a fine black median line, above apex black, towards 

 anal angle grey. Hindwings and cilia dark fuscous-grey. 



Whangarei, Auckland, and Wellington, in December and 

 January ; common amongst forest. 



MICBOPTEKYGIDjE. 



The four additional species here recorded are exceedingly 

 interesting, and the two species of Palceomicra extremely hand- 

 some. All are most difficult to see on the wing, in fact almost 

 invisible ; much more difficult than the European species of 

 Micropteryx. 



Mnesarch^a, Meyr. 



In the two following species the tongue is well-developed, and 

 vein 6 of the forewings is separate ; in all other respects the 

 structure is identical w T ith that of M. paracosma. The antenna? 

 in all the species are clothed with loose hair-scales, arranged in 

 whorls at the joints ; the spurs of the middle tibia? are well- 

 developed. 



Mnes. loxoscia, n. sp. 



Male, female. — 11-1 2 mm. Head white. Palpi dark fuscous, 

 apex broadly white. Antenna? whitish-ochreous, annulated with 

 fuscous. Thorax white, patagia dark fuscous. Abdomen dark 

 fuscous. Legs dark fuscous, apex of joints ochreous-whitish. 

 Forewings lanceolate; white, more or less partially suffused with 

 pale whitish-yellowish ; a dark fuscous blotch occupying costal 

 half of wing from base to f, its posterior edge inwardly oblique ; 

 a dark fuscous streak along inner margin from base, gradually 

 narrowed, terminating in an outwardly oblique triangular dark 

 fuscous spot, the apex of which toucbes lower posterior angle of
