moderate, with strong pecten. Palpi moderately long, second joint exceed- 

 ing base of antennae, clothed with appressed scales, rough and somewhat 

 furrowed beneath, terminal joint shorter than second, slender, recurved. 

 Thorax smooth. Forewings elongate, apex rounded, hindmargiu very 

 obliquely rounded, surface with tufts of scales ; in female abbreviated, 

 broadly lanceolate, Hindwings as broad as forewings, elongate-ovate, hind- 

 margin rounded, cilia -| ; in female much abbreviated, lanceolate or almost 

 obsolete. Abdomen moderate. Posterior tibiae clothed with loose hairs 

 above. Forewings with vein 7 to apex, 2 from hardly before angle of cell. 

 Hindwings normal. 



Allied to Eulechria, differing in the long whorled ciliations of the 

 antennae, the tufts of scales on the surface of forewings, and the abbreviated 

 wings of the female. This and the following genus are closely allied, and 

 are apparently descendants of a single progenitor, both being confined to 

 New Zealand ; these two genera stand in exactly the same mutual relation 

 as Hoplitica and Proteodes.

Male. — 21-24 mm.; female. — 13-18 mm. Head, palpi, and thorax pale 

 fuscous, more or less suffused with dark fuscous. Antennae pale fuscous, 

 slenderly annulated with dark fuscous. Abdomen ochreous-whitish. Legs 

 ochreous-whitish, tarsal joints suffused with dark fuscous towards base. 

 Forewings elongate, somewhat dilated posteriorly, costa moderately arched, 

 apex round-pointed, hindmargin very obliquely rounded ; light fuscous, 

 irregularly or wholly suffused with dark fuscous ; a large tuft of raised 

 scales almost at base, and two or three much smaller in disc ; an obscurely 

 indicated pale dot in disc before %, partially surrounded by a dark ring, and 

 a similar one on fold obliquely beyond it ; a dark fuscous crescentic spot in 

 disc slightly beyond middle, extremities directed downwards, anteriorly and 

 posteriorly distinctly margined with paler ; a slender dark fuscous transverse 

 line from § of costa obliquely outwards, twice angulated above middle, 

 thence running to § of inner margin, often obsolete : cilia pale fuscous, 

 mixed with dark fuscous, with a row of cloudy dark fuscous spots. Hind- 

 wings whitish-grey or grey, with a darker grey discal spot ; cilia grey- 

 whitish, with one or two cloudy dark grey lines. 



Considerably broader - winged, and generally darker, than Brack, 

 sordida. 



An early spring species, occurring tolerably commonly at rest on tree- 

 trunks and fences round Christchurch, in August and September ; the 

 female is quite incapable of flight.
