 thorax fuscous. Abdomen dark fuscous, base of segments and two 

 whole apical segments ochreous-orange. Legs rather dark fus-

Duaringa and Brisbane, Queensland, in November ; rather 

 common in the larval state, but apparently less frequent as imago. 

 Larva 1 6-legged, stout, cylindrical, head large ; dull slaty-grey, 

 spots small, blackish ; head blackish ; it feeds on the bark of 

 Eucalyptus, gnawing it externally beneath a broad shelter of silk 

 and refuse. Pupa in a chamber excavated in solid bark. I 

 found the larva nearly full grown in September.
