ON SOME RIIYNCHOTA , PRINCIPALLY FROM NEW GUINEA 



( AMPHIBICORISAE AND NOTONECTIDAE ). 



by G. YY. KIRKALDY. 



Among the interesting Rhynchota lately entrusted to me for 

 determination by D. r Gestro , is a macropterous example from 

 New Guinea of the remarkable and little -studied Notonectid 

 genus Nychia Stài [= Anlipalocoris Marshall], of which, up 

 to the present, only brachypterous individuals were known and 

 the original example of which was incorrectly assigned to the 

 Corixidae (Sigarida) by the illustrious Swede. The genus is now 

 known from Corsica, Belgian Kongo, Ceylon, New Guinea and 

 China.
