The one in Italy is a different species to that in India. 

 These flies are developed from larvae in ponds and pools of 

 stagnant water, and they can be destroyed by pouring paraffin 

 oil over the surface of the water. The best plan whenever 

 practicable is, of course, to fill in and drain off these ponds. 



Before leaving the subject, I may mention that a 

 malarial expedition has telegraphed home from Bonny, in 

 Nigeria, news of the discovery of another parasite found in 

 the proboscis of mosquitoes, which causes Elephantiasis. 

 You are aware what a terrible scourge this disease is to 

 millions of natives in tropical countries, and that it is due to 

 a minute worm which lives in the lymphatic vessels. 



It is stated in Science Gossip that the discovery has 

 been simultaneously made in England by Dr. Low and in 

 India by Captain James. 



The late Edward Newman wrote in the Zoologist for 

 1872, that "We seem to have ignored these islands in 

 everything but plants and mollusks." 



In 1896 Mr. Tutt stated in the Entomologists' 1 Record, 

 that " The Entomology of Guernsey was better known than 

 that of many an English county.' 1 



Mr. Malcolm Burr states that the Channel Islands 

 species will be included in his forthcoming work on the 

 British Orthoptera. Mr. Claude Morley will also include the 

 Guernsey and Alderney species in his British Ichneumonidce. 



Mr. Lucas has mentioned the names of those species 

 found in Guernsey and Sark in his recently published work 

 on the British Dragon Flies. Mr. Tutt, in his work on the 

 British Lepidoptera has also included Guernsey and Sark in 

 the list of localities given for many of the species, and Mr. 

 A. Fauvel, of Caen, an eminent French Entomologist, has 

 written to me asking for the names of the Coleoptera found 

 in Guernsey and the other islands, as he is writing a catalogue 

 of the species found in Normandy, and wishes to include 

 those found in these islands also. All this serves to show 

 that the work done by our Society is appreciated by 

 naturalists both in England and France. 



I will now conclude by expressing a hope that each 

 member will take up some particular branch of Natural 

 Science, and will enjoy the study as much as I have done 

 during the intervals of a busy life.
