In describing and generically locating this species, I relied on 

 the character given by Stal in his generic diagnosis " tihiis com- 

 pressis,''' and had not then noticed that in a second species he had 

 described the tibiae as " ant/ustce.''' Breddin states tliat he has 

 compared the Ceylonese f(irn) with A. corniculata and is satisfied 

 with their identity. He appears to have been unaware that Ber- 

 groth (1906) had proposed a new genns for its reception, which 

 is certainly, at least, of subgeneric rank. 



Add : IJab. To Ceylon must now be added Java ; Philippines.
