Palpi moderately long, porrect; second joint with very long hairs beneath; 

 terminal joint long. Antennae of d" bipectinate to apex, pectinations very long. 

 Posterior tibiae without middle spurs. Forewings witii 4 and 5 separate, all 

 veins from areole separate, subapical cross-bar from 10 to 9 beyond their bifur- 

 cation. Hindwing-s with 3, 4, 5 separate, 6 and 7 connate or approximated, 12 

 somewhat approximated to cell about middle, not connected. 



? apterous with simple antennae and rudimentary tibial spurs. 



1. Pterolocera amplicoenis.

 signis H-Sch., Lep. Exot., 1858, f. 459. 



d". 35 — 54 mm. Head and thorax densely hairy; pale ochreous-brown, 

 brown, or reddish-brown. Palpi li to 2; brownish or fuscous. Antennae 

 whitish or gTey; pectinations fuscous. Abdomen brownish, reddish-brown, or 

 pale ochreous-brown ; in pale examples the dorsum of basal segments may be 

 darker brown. Legs reddish-brown or brown; tarsi usually fuscous. Forewings 

 broadly or narrowly triangular; costa straight or slightly sinuate, apex pointed, 

 termen bowed, slightly oblique; pale ochreous-brown, brown, reddish-brown, or 

 fuscous-brown; veins sometimes more or less outlined with fuscous; sometimes 

 a faint postmedian fuscous line, or this may be represented by dots on veins; 

 sometimes two, fuscous, antemedian dots in middle and above dorsum; cilia con- 

 colorous. Hindwings with termen only slightly rounded; as forewings. Under- 

 side similar. 



^'ery variable both in shape and colour of forewings, with some t-endency 

 to form local races, but these again are variable. Western Australian examples 

 are usually redder, and in some of them the dots on the forewings are ex- 

 aggerated. 



?. Apterous ; dark- fuscous ; nearly smooth abo\-e, rather hairy beneath ; 

 antennae simple ; tibial spurs rudimentary. A very im-moth-like insect.
