394: Mr. 0. G. Lamb on Exotic Chloropidse. 



OSCINIS, Macq. 

 (ruodo, OscineUa, Becker.) 



The number of examples in this genus is not very large, 

 and several of the very obscure black species are represented 

 by single specimens ; further, a good many were damaged, 

 so that there are only the following that can be made out 

 with fair certainty : — 



0. maura, Fin. 



Several specimens which cannot be separated from forms 

 of tills widely spread species. 



Natal: Durban {F. Mair, Camb. Coll.). 



0. complicata, Beck. 



Specimens from Durban (F. Mair) are quite indistin- 

 guishable from the specimens from the Seychelles on which 

 the species was founded by the author under the name 

 0. oculata (Trans. Linn. Soc. xv. part 3, 1912, p. 340 ; see 

 same, xvi. part 4, 1914 7 p. 370). 



0. maculata, Beck. ? 



There is a single specimen from Africa which is either a 

 bright form of 0. maculata described by Becker (III. p. 158) 

 from New Guinea or a closely allied species of that group, 

 which is characterized by a very undulated 4th vein running 

 just up to the vein-tip. It is unstriped, as are some forms of 

 Becker's species, but is apparently more shining and a little 

 larger. The sternopleural spot is only just visible, owing to 

 the position of the pin.

S. Rhodesia : Salisbury (G. A. K. Marshall). 



0. ornatifrons, Meij.? 



There are two specimens, both rather worn, which accord 

 with fair exactness with the description. The d.-c. bristles 

 are very small, but all the colour-characters of head &c. 

 hold if one allows for the dilapidated state. The only real 

 difference is a slight one in the colour of the legs, these being
