edge of basal patch strongly angulated above middle, beneath connected 

 with a spot on inner margin before middle ; central fascia from before 

 middle of costa to inner margin at f, narrow above, strongly dilated on 

 lower half, margins very irregular ; a triangular patch on costa about f ; a 

 small spot before middle of hindmargin (sometimes conspicuously darker) : 

 cilia ochreous or ochreous-fuscous, with a darker basal line. Hindwings 

 whitish-grey or almost whitish, more or less spotted with darker grey, 

 towards apex sometimes ochreous-tinged ; cilia grey-whitish or ochreous- 

 whitish, with two darker lines. 



Var. a. Forewings with a small round whitish or whitish-ochreous spot 

 in disc between basal patch and central fascia. 



A very variable species, but always characterized by extreme indefinite- 

 ness of marking, and broader-winged than the following. The var. a 

 (described by Walker as distinct under the name of biguttana) I also sup- 

 posed at first to be a good species, but have since seen transitional forms, 

 which leave little doubt that it is merely a varietal development. The 

 purple variety is also very striking and handsome. 



Larva rather stout, cylindrical, somewhat tapering behind, with scat- 

 tered short whitish hairs ; whitish-green, spots hardly darker ; dorsal very 

 distinct, slender, dark green ; head very pale greenish-ochreous. Feeds 

 between joined leaves of Panax arboreum ( Araliaced) in April ; pupa free in 

 same position. This larva produced a specimen of the purple variety in 

 June (indoors). The larva is certainly not confined to this food-plant, and 

 is probably more or less polyphagous. 



Common at Auckland, Wellington, Nelson, Christchurch, and Dunedin, 

 and probably generally, from January to May, and even in July. 

 16. Cac. enoplana, n. sp. 



Media, alis ant. dilute fuscis, costa, linea antica transversa, fascia 

 obliqua lata superius coarctata, trianguloque costas saturate fuscis ; post, 

 albidis. 



Male. — 20 mm. Head, antenna?, thorax, abdomen, and legs whitish- 

 brown ; (palpi broken) ; anterior and middle tibiae and tarsi suffused with 

 dark fuscous except at apex of joints. Forewings moderate, posteriorly 

 dilated, costa moderately arched, hindmargin sinuate, hardly oblique ; light 

 dull brown ; costal edge and fold dark fuscous ; outer edge of basal patch 

 indicated by an irregular dark fuscous line from \ of costa to \ of inner 

 margin ; central fascia dark fuscous towards costa, towards inner margin 

 hardly darker than ground-colour, but margined by dark fuscous lines, 

 running from before middle of costa to before anal angle, very narrow on 

 costa, gradually dilating to middle, very broad on lower half, margins rather 

 irregular ; a fiattened-triangular dark fuscous spot on costa about f : cilia
