cliaractor with that of the rat tribe, and if any member could, 

 on inspection, say what it was the finder would be glad of the 

 information. The three nests referred to were handed round 

 for inspection. 



Mr. Michael said he was not at all a specialist on the subject 

 of bees, but he had some experience in the matter of the nests 

 made by humble-bees, and it appeared to him that they did not 

 confine themselves invariably to one kind or particular class of 

 fibre or hair, so that it was frequently possible to find in the 

 nest of the same bee layers of different kinds of hairs ; they 

 did not seem to be particular as to the material they used, but 

 probably took what was nearest to hand. 



Mr. Rousselet read a paper by Mr. Hood, " On FloscnJaria 

 cucullata,'^ sp. nov., Hood. 



Mr. Western said he had an opportunity of seeing this 

 Floscule, and regarded it as a very interesting addition to the 

 number already described. 



Mr. Rousselet drew the attention of the members to a speci- 

 men of the male of Stephmioceros, which, he believed, was 

 exhibited in the room that evening for the first time. 



Mr. T. B. R/Osseter's paper on Cysticercus quadricurvatus was 

 read by Mr. Yezey. 



Mr. Karop said it was hardly possible to expect much dis- 

 cussion on a paper of that kind, because, unfortunately, no one 

 but Mr. Rosseter seemed to have worked at it, although there 

 were undoubtedly a large number of these forms which it 

 certainly was desirable to know something about. The cysti- 

 cercus would be swallowed with the entomostraca, and would 

 ultimately reach its final host, in the interior of which it would 

 become changed into a tape-worm as usual, but that remained 

 to be discovered, as in so many other cases. 



The Chairman said they were very much obliged to Mr. 

 Rosseter for his very careful observations upon the subject, 

 which was one well worthy of the attention of microscopists, 

 especially in regard to the important part which these organisms 

 might play in their ultimate state. 



The thanks of the Club were unanimously given to the 

 authors of the papers read, and the proceedings terminated 

 with the usual conversazione, at which the following objects 

 were exhibited : —
