tendency ; also from Burnley, the melanie variation of Ematurga atomaria ; 

 Hyria muricata, purple form, and Camovympha typhon var. rothliebii, from 

 Witherslaek ; Nyssia zonaria from the Crosby Sandhills, and the insects captured 

 on the occasion of the Society's field meeting at Mold on June 7th, 1913, 

 including- Lobophora viretata, Cnephasia musculana, Capua favillaceana, Argyro- 

 lepia hartmanniana and Agriopis aprilina (larva). Mr. B. Tait showed a long 

 and variable series of the beautiful melanie form of Boarmia repandata from 

 Penmaenmawr, also bred Agrotis lucemea from the same district ; varieties of 

 Abraxas grossulariata, including- ab. varleyata, bred from various localities in 

 1913 ; Aplecta nebulosa var. robsoni and Geometra papilionaria from Delamere ; 

 Hecatera serena and Calligenia miniata from Sussex. Mr. Tait also gave an 

 account of his collecting holiday in Sussex, from which it appeared that 

 Lepidoptera had been as difficult to obtain in the south of England as in the 

 north during the past summer. Mr. Johnson exhibited a long and fine series of 

 C. typhon, including some very dark forms, from Witherslaek ; also Acidalia 

 fumata, Nisoniades tages, and Lycsena astrarche from the same place. 

 Dr P. F. Tinne, various species of autumn Lepidoptera from the North of 

 Ireland, including a nicely varied series of Cidaria tmncata, several being the 

 var. centumnotata. All the members present reported a very poor season from 

 a collector's point of view. 



Monday, November 17th, 1913.— The President in the Chair. 



Mr. W. Bowater, B.D.S., F.E.S., Brandon Lodge, Bussell Eoad, Moseley, 

 Birmingham, and Arnold W. Hughes, 33, Lacy Eoad, Everton, Liverpool, were 

 elected Members of the Society. 



Br. P. F. Tinne read a paper entitled " Insects concerned in the Pollination 

 of Plants," in which he dealt very thoroughly with the part played by insects 

 in this important process. Dr. Tinne gave many interesting examples, chiefly 

 drawn from the Hymenoptera and Lepidoptera, as to the methods of the various 

 species ; he described the structure of the floral organs of plants which facilitated 

 the operations of the insect principally concerned in the pollination, and also 

 indicated how unwelcome or inefficient visitors were repelled and imprisoned or 

 otherwise prevented from interfering with the process. 



The following exhibits were made .—by Mr. W. A. Tyerman, a fine bred 

 series of Notodonta dromedarius var. perfusc.a, Dianthcecia nana, D. cucubali, and 

 Phibalapteryx vittata from the Southport district: also Sphinx convolvuli, 

 NemeopMla plantaginis, and Callimorpha dominula. A specimen of Chcerocampa 

 nerii captured by a farmer near Ainsdale on September 14th, 1913 ; it was in a 

 very dilapidated condition but easily recognisable, and it forms a very interest- 

 ing addition to our county list. Mr. W. Mansbridge showed a short series of 

 Thera variata and pale forms of T. obeliscata for comparison. — Wm. Mansbridge, 

 Hon. Secretary.
