r84 Mr. P. Cameron on 



type of a new genus. Otherwise the species compares fairly 

 well with Aphelinus. 



Bred from the tea scale insect Aspidiotus thecB from 

 Janygo, where it was bred by Mr. F. W. H. Mills. The 

 group of Aphelinince are parasitic in those destructive pests, 

 the Coccidce. 



Pteromalus oryz^, sp. nov, (PL I. f 2 & 2d). 



Coppery-green, the scape and legs yellow, the femora 

 with a more testaceous tinge ; the mandibles rufo-testa- 

 ceous. Head and thorax closely, and somewhat strongly, 

 punctured ; the antennal groove transversely striated ; the 

 mesopleurae more strongly punctured than the mesonotum ; 

 the metapleurae shining, impunctate ; median segment 

 finely punctured, except at the apex, and with a stout keel 

 down the centre. Abdomen shining, as long as the thorax ; 

 the apical segment conical. Wings hyaline, with a very 

 faint fulvous tinge ; the nervures yellowish. In some 

 examples the femora are infuscated ; the coxse punctured, 

 green ; the flagellum of the antennae may be blackish to 

 testaceous. 



Length nearly 3 mm. 



This species belongs to the sub-tribe Pteromalides of 

 Thomson (Hymenoptera Scandinavia, IV.) ; but to what 

 particular genus, as defined either by the learned Swede or 

 to the more numerous genera of Foerster, it passes my wit 

 to determine ; and in this my valued correspondent. Prof 

 G. L. Mayr, of Vienna, agrees with me. I have, therefore, 

 referred it to the old genus Pteromalus. The ringlet is 

 2-jointed ; the succeeding joint is as long as it united ; the 

 club is 3-jointed (but the joints can only be with difficulty 

 seen); the antennae have thus 13 joints. The parapsidal 

 furrows are obsolete.
