TRANSACTIONS OF THE SOCIETY. 



Monthly Meeting held on January 18th, 1899, Mr. W. A. Luff, 

 President, in the chair. 



Mr. W. A. Luff exhibited a photo of the animal recently 

 caught at Moulin Huet Bay and stated in the newspapers to 

 be a young whale. Mr. Collenette stated that the animal 

 was, however, a dolphin, known as Risso's Dolphin, three 

 specimens of which have been caught near the island in recent 

 years. 



Mr. W. A. Luff also exhibited incrustations on poplar 

 twigs found in his garden, consisting of the dead bodies of 

 aphides closely adjoining (probably Aphis salicis), and Mr. 

 Buckton, F.Z.S., says that these incrustations are very 

 remarkable, and the more so as every individual aphis has 

 been tenanted by the grub and imago of an aphidous hymen- 

 opt erous insect which has cut its exit out of the back of the 

 aphis. These exits were clearly visible as perfectly circular 

 holes, the pieces cut out in some cases remaining unbroken on 

 the twigs. Mr. Luff also exhibited a mass of silk containing 

 cocoons of a species of Braconidce, a hymenopterous parasite, 

 on larvas of various butterflies and moths. As many as 1,200 

 specimens have been reared from a single lepidopterous larva. 



Mr. A. Collenette read his papers on Rain and Sunshine 

 in Guernsey in 1898, and a discussion thereon took place.
