Meybick. — On New Zealand Geometrina. 57 



2. Acidalia, Tr. 

 Palpi moderate, triangularly scaled, porrected. Antennae in male bicili- 

 ated with long tufts of cilia (4-5). Forewings with vein 6 from below 9, 

 7 from above areole, 10 out of 9 above 7, 11 anastomosing shortly with 9, 

 12 free. Hindwings with veins 6 and 7 separate, 8 very shortly anastomos- 

 ing with 7 near base. 



A very large genus, almost cosmopolitan, but only represented in New 

 Zealand by one species, which must be regarded as an established immi- 

 grant from Australia. 



2. Acid, rubraria, Dbld. 

 (Ptycliopoda (?) rubraria, Dbld., Dieff. N.Z., ii., '286, Walk., 781 ; Fidonia (?) acidaliaria, 

 Walk., 1037 ; Acidalia jiglinaria, Gn., ix., 454, pi. xii., 8.) 

 Male, female.— 17-21 mm. Forewings moderate, hindmargin rounded ; 

 light ochreous, reddish-tinged, irrorated with blackish ; a cloudy dark 

 fuscous irregular dentate slightly curved line about J, a second in middle, 

 and a third more blackish and followed by a narrow fuscous band at f ; a 

 subterminal row of cloudy fuscous spots ; a small black discal spot on second 

 line ; a hindmarginal row of black dots, sometimes confluent. Hindwings 

 moderate, hindmargin somewhat projecting in middle ; rather more reddish 

 than forewings ; a cloudy dark fuscous line before middle ; a small black 

 discal spot ; three irregular dentate cloudy dark fuscous lines between 

 middle and hindmargin, last two often forming rows of spots ; a hindmar- 

 ginal row of blackish clots, often confluent. 



Somewhat variable in intensity of colouring, but not otherwise ; no 

 difference between Australian and New Zealand specimens. 



Napier, Wellington, Nelson, Christchurch, Mount Hutt, and probably 

 everywhere, except perhaps in the extreme south ; also common to New 

 South Wales, Victoria, and Tasmania ; in very dry grassy places, in Sep- 

 tember, January, February, and March, very common ; thirty specimens. 



2. LABENTIDyE. 

 Forewings with areole single or double, vein 11 anastomosing with or 

 rising out of 10, 12 free, rarely receiving 11. Hindwings with 8 veins, 8 

 anastomosing with 7 from near base to near transverse vein, rarely con- 

 nected only by a bar near transverse vein, 6 and 7 almost always stalked. 



The genera represented from five natural groups or sections, 

 la. Areole single.
