170 Transactions. — Zoology. 



an angulated fascia-like spot towards apex : cilia whitish-grey. 

 Hindwings and ciHa whitish-grey. 



Auckland, Wellington, and the Otira Eiver (1,500ft.) ; six 

 specimens amongst forest, in December and January. A dis- 

 tinct but inconspicuous species. 



Calicotis, n. g. 



Head smooth ; ocelli present ; tongue rudimentary. An- 

 tennge f, in male rather stout, filiform, basal joint broadly 

 dilated, excavated beneath to form an eyecap, rough-scaled 

 on posterior edge, without pecten. Labial palpi long, curved, 

 ascending, smooth-scaled, terminal joint shorter than second, 

 acute. Maxillary palpi obsolete. Middle tarsi with long pro- 

 jecting spines at apex of two basal joints ; posterior tibiae clothed 

 with dense long rough hairs above and beneath, posterior 

 tarsi with whorls of long projecting spines at apex of all joints. 

 Forewings with vein 1 simple, 2 and 3 absent, 4 from angle of 

 cell, 7 and 8 stalked, 7 to costa, 11 from | of cell. Hind- 

 wings -|, linear, cilia 7 ; vein 4 absent, cell open between 3 

 and 6, 5 free rising from base, 6 and 7 from a point. 



Allied to Stathmopoda, but differing especially by the 

 greatly dilated and excavated basal joint of antennae, and by 

 the entire absence of the long antennal ciliations. In repose 

 the imago bends the posterior legs to form an angular arch, 

 and extends them horizontally at right angles to the body. 

 The habits of the larva are known, and interesting. 



24. C'al. crucifera, n. sp. 



<? ? . 9-12mm. Head, palpi, antennae, thorax, abdomen, 

 and legs very pale whitish-ochreous ; terminal joint of palpi 

 with a dark fuscous line on outer edge ; anterior legs sufiused 

 with blackish in front, posterior legs spotted with black on 

 apex of joints. Forewings elongate, very narrow, broadest 

 near base, long-pointed ; ochreous- whitish, more or less irre- 

 gularly suffused or blotched with ochreous ; a small cloudy 

 dark fuscous spot on inner margin near base, and another on 

 costa slightly before middle, both in female sometimes almost 

 obsolete ; an apical black dot : cilia grey-whitish. Hindwings 

 whitish-grey ; cilia gi'ey-whitish. 



Larva 16-legged, moderately stout, cylindrical, active ; 

 whitish flesh-colour, or whitish; head pale whitish-brown. 

 Feeds on Platyccrium grande (a large parasitic fern, gi'owing 

 on tree-trunks), burrowing amongst the ripe fructification 

 beneath the fronds, forming galleries of loose refuse ; found in 

 March.. 



Taranaki and Palmerston, in February and March ; com- 

 mon amongst its food. The species occurs also plentifully in 

 the Botanical Gardens at Sydney, but I have not yet met
