o/ Australian Pyralidina. 69 



Balanotis, n. g. 

 Clypeus with a slight transverse ridge, or flat. Ocelli present. 

 Tongue well developed. Antennse in male stout, dentate, mode- 

 rately cihated with tufts of hairs (| to 1). Labial palpi rather 

 long, curved, ascending, second joint smooth, terminal joint 

 short. Maxillary palpi short, fihform. Fore wings with vein 1 

 furcate, 4 and 5 separate. Hind wings with veins 4 and 5 separate 

 or from a point, 6 and 7 short-stalked, 8 fi-ee. Fore wings in male 

 with a thickened glandular sweUing beneath costa beyond middle. 



Specially characterised by the glandular swelling of 

 the male, which is circular, and appears solid when cut 

 through ; the veins which should pass through the space 

 occupied by this are bent so as to pass round it. In 

 B. reciirralis the upper margin of the cell is unusually 

 short. B. didymalis is only known to me in the female 

 sex, and is conjecturally referred here ; it agrees in non- 

 sexual characters. The larva of one species is known ; 

 it feeds in stiff silken tubes amongst the leaves of a 

 Myrtaceous shrub. The genus has evident relationship 

 with the Epipaschiadce.
