INSECTS 



while there are other species, of which no male has ever been detected, 

 though perhaps the females abound. Thus we have more or less perfect 

 parthenogenesis. Yet here again there is a difference ; the offspring of 

 some of these parthenogenetic females are almost all males, while in others, 

 such as those in which no male is known, the offspring are all or nearly 

 all females. 



No one in Sussex has, I think, systematically collected the Tenthre- 

 dinidas, but through the occasional collecting by Messrs. E. A. Butler, 

 E. W. Andrews, W. Bennett, etc., I am able to give a very fair list of 

 the species of the Hastings district. Those from the neighbourhood of 

 Lewes are on the authority of Mr. J. H. A. Jenner, while for the west of 

 the county I have a short list of species met with by Miss Ethel 

 Chawner at Storrington and another from Mr. Guermonprez of Bognor. 

 Of those met with by him in that district almost all have been deter- 

 mined or confirmed by the Rev. F. Morice, who has also helped in many 

 ways. 



I have employed as far as possible the nomenclature of Konow, 

 but as this seems in a very unsettled state I have generally given as 

 synonyms the names under which these insects are described in Cameron's 

 British Phytophagous Hymenoptera.
