Rhyparochromus leucoceras. Walker, Cat. Het. Hemipt., Brit. Mus., 



pt. v., p. 101. 



One of the specimens from Murray Island seems to me to 

 be identical with Walker's type from Ceylon, in the British 

 Museum. 



Dieucbes otescairipes (Wlk.). 



Rhyparochromus obscuripes. Walker, Cat. Het. Hemipt., Brit. Mus,, 



pt. v., p. 104. 



There is a single example of this species from Murray Island. 

 Walker's type in the British Museum is from New Guinea. 



I am strongly of opinion that these two will prove mere colour 

 varieties of a single scarce but widely-spread species.
