median fascia parallel to this, connected by a bar with costa 

 at f , and a narrow fascia from costa before apex to anal angle, 

 but these are sometimes incomplete or partially suffused ; in one 

 specimen, traces of a longitudinal white median streak: cilia 

 brownish-ochreous, with a dark fuscous spot at apex. Hind- 

 wing ovate-lanceolate, apex acute, hindmargin sinuate ; grey, 

 towards apex darker ; cilia grey. 



Larva 16-legged, moderate, cylindrical, rather tapering at 

 both ends ; dull light greenish - ochreous ; dorsal narrow, 

 ochreous-whitish, bordered on each side by a slender dull 

 reddish-fuscous streak, coalescing towards extremities ; head 

 brownish-ochreous. Feeds amongst loosely spun-together leaves 

 of Podocarpus totara (Conifera). Pupa in a thin cocoon. 



Otira Eiver, Dunedin, and Invercargill, in September, 

 December, and January ; five specimens ; larvae found in Decem- 

 ber produced an imago in January. 



10. Plutella, Schrk. 



Head with loosely appressed hairs ; ocelli present ; tongue 

 well developed. Antennas f , towards base somewhat thickened, 

 serrate, in male simple, basal joint moderate, with a dense 

 anterior flap of scales. Labial palpi moderately long, recurved, 

 second joint beneath with long dense projecting tuft of scales 

 towards apex, terminal joint as long as second, slender or 

 somewhat rough anteriorly, acute. Maxillary palpi very short, 

 filiform. Posterior tibiaa shortly haired beneath. Forewings 

 with vein 1 furcate, 2 from rather near angle, 7 to hindmargin, 

 11 from or before middle of cell, secondary cell more or less 

 well-defined, all veins separate. Hindwings as broad as fore- 

 wings or somewhat broader, elongate-ovate or ovate-lanceolate, 

 cilia f-lj ; veins 3 and 4 more or less remote, 5 and 6 stalked 

 or separate, 7 remote. 



The known larvae are 16-legged, somewhat tapering to both 



ends, and all feed on Crucifera. Probably none of the three 



following species is indigenous : —
