attenuated, terminal joint long, exposed. Posterior tibi?o fringed 

 with hairs above. Forewings elongate, narrow, costa in male 

 simple, moderately arched, apex acute, hmdmargin oblique ; 

 surface with raised scales. Hind wings rounded, elongate-ovate, 

 broader than forewings. Forewings with veins 7 and 8 separate, 

 7 running to hindrnargin, secondary cell absent, upper fork of 

 vein 1 obsolete. Hindwings with 6 veins, 3 and 4 stalked from 

 posterior angle of cell, 5 from upper angle of cell to apex, 6 free. 



This genus has a peculiar facies from the remarkably narrow 

 and elongate forewings ; in the structure of the palpi it resembles 

 ffeliocosma, but the singular neuration of the hindwings causes it 

 to be classed with Oistophora and Coscinoptycha as forming a 

 peculiar and abnormal group, probably confined to the Australian 

 region. 



The two species (one Australian, the other from New Zealand) 

 may be easily distinguished ; 



a. Forewings faint whitish-grey . . . . . . 1 . aquilana. 



b. Forewings densely irrorated with dark grey ..2. adreptella. 



1. Par. aquilana n. sp. 



$ ? . 5"-6". Head, antennae, thorax, and abdomen white. 

 Palpi white, beneath sharply dark fuscous. Legs whitish, 

 anterior tibia) and tarsi greyish- tinged. Forewings very narrow, 

 costa gently arched, hindmargin nearly straight, very oblique ; 

 white, almost wholly suffused with faint pale grey except 

 towards anterior half of costa, and with very fine scattered dark 

 grey scales; five sharply defined very oblique short black 

 strigulro on costa between middle and apex, and one shorter 

 (sometimes absent) on costa before middle; a large sharply 

 defined black dot in disc at two-thirds from base, followed by 

 some raised scales; a small tuft of raised scales before this, 

 another below it, two others in a straight line between this lower 

 one and the base at equal distances, and sometimes another 

 obliquely above and beyond the anterior of these, each of these
