A. nigrolabris Smith, is, in my opinion, only a broader variety, in which the light 

 band below the suture is wider : in a box of specimens from Halemano forms are found 

 showing a graduation from it to the typical form. It is possible that A. rudis may be 

 a distinct species, but I fancy it is only a paler colour variety. Mr Perkins notes that 

 he found the species "mostly on dead branches of trees, covering itself with mucus to 

 which debris of bark and wood stick, and therefore very well concealed."
