510 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



pecten. Palpi moderate or long, second joint exceeding base of 

 antennse, densely scaled, almost smooth, terminal joint shorter than 

 second, slender, recurved. Thorax smooth. Forewings elongate, 

 moderate, hindmargin obliquely rounded. Hind wings rather 

 narrower than forewings, elongate-ovate, hindmargin rounded, 

 cilia p. Abdomen moderate. Middle tibiae much thickened with 

 dense rough hairs ; posterior tibiae clothed with dense long hairs. 

 Forewings with vein 7 to hindmargin, 2 from angle of cell. 

 Hindwings normal. 



Differs from Philobota principally by the dilated hairs of the 

 middle tibise ; the exact affinity of the genus is at present some- 

 what uncertain. The second species is only known in the Q, and 

 its position here is therefore not assured. Both recall some forms 

 of Peltophora.
