grey, tending to form transverse strigulte ; costa very shortly spotted with 

 fuscous ; a blackish spot at base beneath costa, with a very strong posterior 

 projection, and a shorter one beneath ; a brown fascia near base, parallel to 

 hindinargm, posteriorly black-margined, anterior edge straight, posterior 

 edge twice sinuate-concave ; a small blackish mark on inner margin beyond 

 middle ; an irregular brown partially black-margined fascia from costa 

 before middle to anal angle, anterior edge with a short median projection 

 ending in a transverse blackish mark, posterior edge emitting from middle 

 an irregular moderately broad branch to costa before apex. Hindwings 

 moderate, hindmargin rounded, crenate ; grey, paler towards base ; three 

 faint discal dots and a sinuate line beyond middle indistinctly darker. 



Appears to vary very little. 



From the female of a pair taken in coj). Mr. Fereday obtained eggs which 

 hatched out in February, but the young larva3 refused all kinds of food- 

 plants offered, and died. At this stage they were 10-legged, very slender, 

 dark purplish-brown, almost black ; spiracular creamy-white, wrinkled ; 

 head shining pale brown.

 (Mr. E. W. Fereday) ; four specimens. Felder gives it from Australia ; 

 this certainly requires confirmation.

Face rough. Palpi rather long, second ascending, roughly scaled, with 

 long hairs beneath, terminal joint long, slender, clavate, porrected. An- 

 tenna? in male bipectinated (2^-5). Femora and under-side of thorax 

 clothed with very dense long hairs. Forewings with rough scales. Fore- 

 wings with vein 6 from below 9, 7 from angle of areole, 10 rising out 

 of 9 and anastomosing again moderately with 9, 11 anastomosing mode- 

 rately with 10, 12 free. Hindwings normal, veins 3 and 4 sometimes 

 stalked. 



D. floccosa has veins 3 and 4 of the hindwings stalked, D. crassitibia 

 separate.
