t)y fellow-collectors, that P. Kliuji, P. spinicoxis, and P. ruber are 

 found among them, hut of course I can only speak at present of 

 those species which have come under my personal observation. 



" Pentaplatarthrus paussoides lives, as stated above, in the 

 large nests of Aphanogaster barbara, var. capensis, Mayr, and in 

 such numbers that close to the sea-side Mr. R. Trimen has 

 captured no less than 76 specimens in one nest. 



" In spite of all my attempts I have not been able to rear the 

 Paussi. They copulate freely in captivity, but their eggs, if laid, 

 have not been hatched." 



Mr. J. B. Bridgman communicated "Additions to the Rev. T. A. 

 Marshall's Catalogue of British Ichncumonidcc." 



Professor Riley read "Notes on the Phytophagic Habit, and on 

 Alternation of Generation, in the genus Isosoyna." In this paper 

 Professor Riley described, from direct observation, the phyto- 

 phagic habit in two species, and, from other evidence, in three 

 other species of the genus. He also established the existence of 

 alternation of generation, which was believed to be the first 

 recorded instance in the Chalcldklce.
