30 Transactions. — Zoology. 



oblique ; white, closely and finely in-orated with dark grey ; generally a 

 slight brownish or ochreous tinge along basal two-thirds of costa, some- 

 times extending over whole wing ; sometimes a dark grey suffusion on 

 middle of costa ; a small dark fuscous elongate mark on inner margin close 

 to base ; a double indistinct dentate dark grey line from costa before middle 

 to inner margin at ■§- , often wholly absent or obsolete ; a dark grey circular 

 ring in disc slightly beyond middle, in centre of which is a dark grey 

 elongate dot, both often absent, or the dot only visible ; a double often well- 

 defined dentate dark grey line from costa at |- to inner margin before anal 

 angle, shortly angulated inwards immediately beneath costa, and outwards 

 above middle, often wholly absent ; a dark fuscous hindmarginal line ; a 

 row of from six to eight small black dots on hindmargin : cilia light shining- 

 grey, more or less distinctly narrowly barred with white, with a darker grey 

 line near base, and extreme base white. Hindwings ochreous-grey- whitish, 

 hindmargin narrowly suffused with light fuscous-grey ; cilia ochreous- 

 whitish. 



Very variable, but very distinct by the narrow wings, grey colouring, 

 and entire absence of white markings or longitudinal streak. 



Abundant on the hills round Christchurch in March ; I have also seen 

 specimens from Lake Guyon, which were somewhat larger, with the dark 

 markings more intense. 



15. Cr, harpojyliorus, n. sp. 



Male. — 26-27 mm. Head whitish, with a faint ochreous spot in middle 

 of face, and posterior margin of eyes greyish-ochreous. Maxillary palpi 

 white, towards base externally dark fuscous mixed with ochreous. Labial 

 palpi moderate, fuscous-grey, internally and at base beneath snow-white. 

 Antennae dark fuscous. Thorax grey, with a whitish spot in middle of 

 anterior margin. Abdomen grey-whitish, posteriorly suffused with pale 

 ochreous. Legs light fuscous- grey, posterior pair more whitish. Fore- 

 wings rather narrow, posteriorly dilated, costa slightly sinuate in middle, 

 gently arched posteriorly, apex rounded, hindmargin moderately oblique, 

 rounded ; grey, very slightly brownish-tinged ; a slender ill-defined central 

 streak of white scales from base to beyond middle of disc, its extremity bent 

 downwards and then sharply turned inwards to form a strong hook ; upper 

 edge of this streak margined by a very slender dark grey line, forming an 

 abrupt spot on extremity, lower edge margined by a dark fuscous-grey 

 streak, filling up the hook ; a slender ill-defined sinuate longitudinal streak 

 of white scales in disc from ^ to § , its anterior extremity resting on upper 

 margin of basal streak, its lower edge broadly and suffusedly margined with 

 dark fuscous-grey until it touches basal streak, its upper edge marked with 

 a dark fuscous dot before extremity, surrounded with a few whitish scales ;
