Tlie promising nature of the field developed by Silvestri led 

 tlie Board to dispatch a second expedition to West Africa which 

 left in June of last year. The writer and J. C, Bridwell went out 

 this time, Prof. Silvestri being unable to obtain a leave of absence 

 from the government school where he is employed. The main 

 object of the second expedition was to get as many as possible of 

 the parasites observed by Silvestri on the previous excursion and 

 any others which might be discovered by us. The expedition

 it extremely doubtful whether we could secure a colony of the 

 Mediterranean fruit fly in TsTigeria a good supply was obtained in 

 Teneriffe and taken with us. On arrival at Lagos we went immed- 

 iately to the office of the Colonial Secretary, who promised us 

 all the assistance the Government could give, and wired immedi-
