Meykick.— On New Zealand Geometrina. 97 



28. Hybeenia, Latr. 



Face smooth. Palpi short, roughly scaled, porrected. Antennae in 

 male bipectinated (5-6). Female semiapterous. Forewings with vein 6 

 from below 9, 7 out of 9, 10 separate, 11 obsolete (probably coincident 

 with 10), 12 free. Hindwings normal. 



A small genus, occurring also in Europe ; the only one in New Zealand 

 in which the female is semiapterous, or vein 11 of the forewings absent. 

 72. Hyb. indocilis, Walk. 

 (Zermizinga indocilisaria, Walk., 1530 ; Hybernia boreophilaria, Gn., E.M.M., v., 61.) 



Male. — 25-34 mm. Forewings moderate, hindmargin rounded, crenu- 

 late ; pale fuscous-grey, closely irrorated with dark fuscous ; a somewhat 

 irregular curved cloudy dark fuscous line at J ; an irregular median line ; 

 a third beyond middle, twice sinuate ; a fourth towards hindmargin, some- 

 times followed by a very obscure whitish dentate subterminal line ; a 

 blackish hindmarginal line. Hindwings moderate, hindmargin somewhat 

 obtusely projecting in middle, crenulate ; colour as in forewings; a curved 

 obscure line before middle ; a dark fuscous discal dot ; a distinct hardly 

 sinuate dark fuscous line beyond middle ; an obscure darker subterminal 

 shade ; a blackish hindmarginal line. 



Female. — 12-14 mm. Wings exceedingly narrow, apex suddenly dilated, 

 angles acute, hindmargin dentate ; colour and markings as in male, but 

 lines black and sharply marked. 



Tolerably constant. 



Christchurch and the plains near, from July to January. Mr. E. W. 

 Fereday states that the male is found plentifully amongst Leptospermum, at 

 rest on the bare ground, and the female on the stems ; thirty-five specimens. 

 I have corrected Walker's inadmissibly barbarous name. 



29. Zylobaea, Butl. 



Face with somewhat projecting scales. Palpi moderate, roughly scaled, 

 porrected. Antennas in male bipectinated (9-12). Forewings with vein 6 

 from below 9, 7 out of 9, 10 and 11 separate, 12 anastomosing shortly with 

 11. Hindwings normal ; 1 a distinct. 



73. Zyl. fenerata, Feld. 

 (Rhyparia fenerata, Feld., cxxxi., 7; Zylobara fenerata, Butl., Cist. Ent., h\, 498.) 

 Male. — 33-35 mm. Forewings moderate, hindmargin unevenly rounded, 

 crenulate ; very pale whitish-grey, slightly ochreous-tinged, irrorated with 

 dark fuscous ; scattered dark fuscous marks indicating several fragmentary 

 dentate lines and a discal spot ; a double cloudy dark fuscous dentate sub- 

 terminal line, distinct throughout ; a row of large black dots on hind- 

 margin. Hindwings oblong, inner margin extremely short, lower margin
