3. Eritarbes otiosa Wism. Co. 
Antennae (—1), slightly serrate; basal joint with single pecten. Labial Palpi recurved, divergent, reaching 
the length of the head beyond it; both joints somewhat thickened with smoothly appressed scales. 
Maxillary Palpi minute, Haustellum moderate. Ocelli present. Head and Thora smooth. Porewings 
elongate-lanceolate, without tufts of raised scales: neuration 12 veins ; 7 and 8 stalked, to costa; 6 out, 
of 7 beyond 8; 5 out of stalk of (6+7+8); 9 connate with stalk of 8-5, rest separate; 1 basally 
furcate. Hindwings (~4), linear-lanceolate, cilia 5-8: neuration 8 veins; 6 and 7 stalked, rest 
separate, 4 closely approximate to 5. Abdomen moderate. Legs, hind tibiae rough-haired above. 
This genus agrees in neuration with the description of the Australian Haplochrots 
Meyr. { Pr. Lin, Soc. NSW. 22 310 (1898)], but the different palpi and narrower hind- 
wings easily separate Hritarbes from Meyrick’s genus, which would appear to contain 
two forms differing in the origin of vein 5 in the forewings, 
1, Eritarbes otiosa, sp. n. (Tab. I. fig. 11.) 
Antennae smoky fuscous, becoming silvery white on their terminal fourth. Palpi bronzy fuscous on their 
inner sides, blackish externally. Heud bronzy fuscous. Z'horax dark smoky fuscous, with a brownish 
tinge posteriorly. orewings dark olivaceous brownish, much suffused with smoky fuscous, especially 
along the costa and at the apex, including the apical cilia, the only indication of any marking being a 
minute blackish dot in the fold beyond its middle; dorsal cilia dark smoky grey. Hwp. al. 8-85 mm. 
Hindwings brongy fuscous; cilia dark smoky grey. Abdomen dull smoky fuscous. Legs smoky fuscous,
