This is a variable species as regards the tinting of the tegmina, 

 which are sometimes clear and not shaded on the basal lialves ; it 

 is even apparently more unusually variable in the position of the 

 opercnla, which in some specimens examined, probably owing to a 

 shrinkage of the abdomen, reach its apex ; in other examples the 

 apices of the opercula are much less angularly produced than in 

 typical specimens. 



Miss Dendy, who collected specimens of this species at Darjiling, 

 which she presented to the British Museum, wrote : " These 

 creatures make a noise like a watchmau's rattle in the trees at 

 night." 



Opercula in male medially lobate on each side, reaching ^^osterior
