I originally described this sp 'cies from the Transvaal 

 founded on three small specimens which each onlv measured 

 10 mm. 1 have since received other examples from the same 

 locality vvbich are lo mm. in length. Bergroth's type of his 

 JJ. confusa (of which he gives no dimensions in Jiis descrip- 

 tion) also has a length of 13 mm. 



Bergroth's differential characters of D. plana and D. con- 

 fusa (as regards the colour of the antennse, the comparative 

 lengths of the second and third joints of same, and the 

 length of the hemelytra) are unreliable characters^ and he 

 confesses that in some specimens these ^'' are less obvious ^^ ; 

 but I quite agree with him that the species can be " always 

 easily distinguished by the quite ditt'erent structure of the 

 genital segment," and he is to be congratulated on having 

 observed that character. It is, however, much more pro- 

 nounced in some specimens than in others. The Biit. Mus. 

 now possesses specimens from Transvaal; Lydenburg Disti., 

 Zuutpansberg, Biet iietief; iS. Africa {Dr, Smithes Coll.), 

 Livingstonia {Simon) ; Mashonaland, Salisbury {Marshall) ; 

 ^yasaland {Coiterell). 



Halyomorpha viridescens. Walk. I^A(elocera). 



Bergroth (Rev. Zool. Afr. iii. p. 450, 1914) has redescribed 

 this species, but at the same time only a peculiar form of it, 

 for it 16 of a very variable nature, as 1 pointed out iu 1880
