 Four of these Thomas recognises as distinct, viz: — jpaliari, famu- 

 lus^ coohii and nitidulus (differentiating a subspecies of nitidulus) 

 from Mt. Popa. The rest he lumps together, as a group, under 

 the name hooduga, pending further study. These forms may be 

 arranged in a key as follows : —
