Hab. N. W. Australia—Port Darwin, Adelaide River. 
Many specimens of both sexes. In the male of this 
insect the anterior femora are subangularly dilated on the 
inner side towards the base; of this no mention is made 
by Mr. Blackburn. I have examined the types of 7. 
punctipenne, Pasc.; the length given 24 millim.” is 
evidently a misprint for “54 milim.” Mr. Blackburn’s 
specimens of ‘1’. addendwm were from the northern 
territory of South Australia. Found under logs and 
loose bark (Walker).
