Meyrick. — On Neiv Zealand Micro-Lepidoptera. 137 



margins paler ; a narrow white streak almost along costa from base to apex, 

 leaving extreme costal edge of ground-colour, more widely posteriorly, 

 posterior extremity suffused ; a moderate straight white central streak from 

 base to middle of hindmargin, narrowed anteriorly; inner margin suffusedly 

 white from base to beyond middle ; cilia snow-white. Hindwings ochreous- 

 grey-whitish, becoming greyer posteriorly ; cilia white. 



Very similar to G. dicrenellus, but with the apex of the forewings less 

 pointed and the hindmargin less sinuate ; readily distinguishable by the 

 uppermost white streak being subcostal instead of costal. 



Lake Wakatipu, taken commonly on the dry mountain slopes at from 

 2,000 to 5,000 feet, in December. 



27. Cr. pedias, n. sp. 



Male, female. — 24-27 mm. Head white, behind eyes pale greyish- 

 ochreous. Palpi very long, pale ochreous, above and internally white. 

 Antennae whitish, in male serrate, shortly ciliated. Thorax pale greyish- 

 ochreous, with a central longitudinal white stripe. Abdomen grey-whitish. 

 Legs whitish-ochreous, posterior pair whitish. Forewings very elongate- 

 triangular, narrow, not much dilated, costa slightly arched, apex almost 

 acute, hindmargin sinuate, oblique; very pale dull greyish-ochreous ; costal 

 edge except towards base, and all veins narrowly and suffusedly white, 

 obscurely margined with fuscous ; a whitish obscure suffusion towards 

 inner margin ; a narrow nearly straight white central streak from base to 

 hindmargin somewhat above middle, slightly bent beyond middle, obscurely 

 fuscous-margined ; a row of small blackish dots along hindmargin : cilia 

 shining greyish-white, with a shining whitish-grey basal line. Hindwings 

 ochreous-grey-whitish, towards apex greyer ; cilia white. 



Most like C. callirrhous, but much duller and greyer, not brassy-tinged, 

 and without the sharply defined white lines of that species ; the antennas 

 are whitish, not distinctly dentate in male, and the hindmargin of forewings 

 is somewhat more sinuate, distinctly dotted with black. 



Masterton and Wanganui, on the grassy river-banks; common in March. 



28. Cr. parascenus, n. sp. 



Male, female. — 28-31 mm. Head white, on centre of face and behind 

 eyes ochreous. Palpi very long, ochreous, above and internally white. 

 Antennas dark fuscous, in male serrate, moderately ciliated. Thorax pale 

 ochreous, with a suffused white central longitudinal stripe. Abdomen 

 whitish. Legs ochreous-fuscous, posterior pair whitish. Forewings very 

 elongate-triangular, narrow at base, moderately dilated, costa gently arched, 

 apex round-pointed, hindmargin almost straight, rather strongly oblique ; 

 light yellowish-ochreous, slightly brassy-tinged, sometimes fuscous-tinged 

 in disc ; extreme costal edge white from about middle to apex ; a moderate
