with the Professor's own experiences during an expedition undertaken to dis- 

 cover the breeding habits of the Glossinidse, was most interesting, especially 

 the account of the finding of the first pupa of Glossina morsitans, and of the 

 connection between this fly and sleeping sickness and " ingana." A capital 

 photograph shown on the screen recorded this historic event. 



Mr. A. W. Hughes exhibited Phigalia pilosaria, including a pale olive 

 unicolorous variety, from Eastham, also Hybernia leucophearia and var. rnarmo-

 Liverpool. The President in the Chair. 



Mr. A. W. Boyd, M.A., F.E.S., gave an address entitled "The Natural 

 History of Rostherne Mere." Having described the physical characters of the 

 Mere and the probable causes of its formation, the nature of the surrounding 

 land and its flora, both arboreal and herbaceous, he dealt exhaustively with the 

 birds known to frequent the Mere and finally the insects of the locality were 

 discussed. Several very interesting records have been made, viz., Acidalia 

 circellata, a fine female specimen in 1913 ; Ornix avellanella, Laverna raschkiella, 

 this species being an addition to the Lancashire and Cheshire county list, and 

 Nepticula argentipedella. Mr. Boyd exhibited the Lepidoptera catalogue for 

 the locality, and was congratulated upon having made such good use of the 

 opportunity of collecting upon the private ground surrounding the Mere. At 

 the close of the address, Mr. Boyd was heartily thanked for his kindness in 

 coming from Manchester to give his experiences. 



Mr. W. Mansbridge exhibited several xanthic varieties of Fidonia atomaria 

 bred among a large number of the species from Burnley females. The xanthism 

 was confined to the hind-wings, and in most of the specimens it affected only 

 one of the hind-wings ; in two instances, however, both the secondaries were 

 nearly white all over. Mr. F. N. Pierce, generic types of the British Geome- 

 tridse, arranged according to their affinities as indicated by the genitalia. —

 attack of a mite on lime at Mickleham. Mr. B. Adkin, aberrations of Colias
