paler and sometimes greyish towards tips. Hindwings grey, somewhat 

 darker towards apex ; cilia ochreous-whitish or grey- whitish, sometimes 

 with a cloudy grey line. 



Very variable, but hardly to be confused with any other ; immediately 

 known from the two preceding species by the grey hindwings and smaller 

 size. 



Wellington, Christchurch, Lake Wakatipu, in December and January ; 

 generally common on bare grassy hills ; at Lake Wakatipu it occurred 

 sparingly up to an elevation of 4,000 feet. 



29. Gymn. tholoclella, n. sp. 



Minor, alis ant. fuscis, ochreo-conspersis, punctis disci tribus saturatio- 

 ribus ; post, griseis. 



Male, female. — 12-13 mm. Head, palpi, and thorax light brownish- 

 ochreous, more or less mixed and suffused with dark fuscous. Antennas 

 brownish-ochreous, annulated or suffused with dark fuscous. Abdomen 

 grey-whitish, anal tuft whitish-ochreous. Legs dark fuscous, central ring 

 of anterior and middle tibias and apex of all joints whitish, posterior tibiae 

 with whitish hairs. Forewings moderate, somewhat dilated, costa moder- 

 ately arched, apex obtuse, hindmargin oblique, hardly rounded ; light 

 brownish-ochreous, densely mixed and irregularly suffused with dark 

 fuscous ; generally a clear pale spot on costa before middle ; a cloudy 

 round dark fuscous dot in disc before middle, a second, oblique and some- 

 times obscurely double, in disc beyond middle, and a third on fold obliquely 

 beyond first : cilia pale ochreous, with a cloudy dark fuscous line near base. 

 Hindwings grey ; cilia pale ochreous, with a faint fuscous line. 



Not nearly resembling any other ; the pale ochreous cilia contrast 

 noticeably with the ground-colour on both wings. 



Hamilton, Palmerston, Christchurch, Dunedin, from January to March ; 

 common, and sometimes very abundant, in forest ; probably of general 

 occurrence.

 quinque posticis serieque marginis postici saturate fuscis ; post, dilute 

 griseis. 



Male. — 17 mm. Head, palpi, antennas, thorax, abdomen, and legs pale 

 whitish-ochreous ; second joint of palpi externally, and anterior margin of 

 thorax suffused with dark fuscous ; anterior and middle tibias dark fuscous 

 with pale central and apical rings, tarsi banded with dark fuscous. Fore- 

 wings moderate, costa moderately arched, apex obtuse, hindmargin straight, 

 oblique ; pale whitish-ochreous, finely and scantily irrorated with fuscous
