being at all times constant. It was noted that these two 

 species were accustomed to roost in holes in banks and walls, 

 which they carefully investigated previous to occupation. 



JUNE gih, 1904. 



The President in the Chair. 



Dr. Chapman exhibited ova of Coleophora laricclla, laid by 

 a female bred by Mr. Turner from the Isle of Purbeck. He 

 stated that they were upright eggs with the micropyle at the 

 top, which was composed of 5 to 7 large " cells," from which 

 thirteen or fourteen very bold ribs sprang and ran down to 

 the base. They were laid on the lower sides of the needles 

 of larch. He also showed the cocoon of Thais polyxena, which 

 consisted of a few strands of silk attached to twigs. 



Mr. Lucas exhibited a fungus, Epichloe thypina, very 

 commonly parasitical on grasses, upon which the larva of a 

 fly was feeding. He showed photographs of the ova, the 

 larva, and the channels of the larva in the fungus. The in- 

 cipient spore-bearing under-layer was the portion consumed. 

 (The resulting imagines bred from these larvae were afterwards 

 determined by Mr. G. H. Verrall to be a dipterous species — 

 Anthomyia spreta, Giraud). 



Mr. Lucas also exhibited ova of the large ladybird, Halyzia 

 occllata, and specimens of parasites (Mymaridai) on the ova 

 of Orgyia antiqna. 



Mr. West exhibited specimens of the Capsid Harpocera 

 thoracica, the females of which he had taken, at dusk, on 

 Ranmore Common ; he called attention to their curiously 

 knotted antenna. 



Mr. Carr exhibited ova oi Acidaliarcunitaria. 



Mr. Turner exhibited cases and larvae oiC oleophorabicolorella, 

 a very local species, which he had met with in some numbers 

 at Chatham feeding upon nut. He stated that unlike most 

 species of the genus the larvae fed upon the most exposed 

 part of the bushes, three and four cases being frequently 

 found on one leaf at the top of the highest shoot. 



An interesting discussion took place on the Season. 

 Mr. Harrison said that in the early spring insects were 

 fairly common, but at Whitsun in the New Forest collect- 

 ing was practically a failure. Nothing could be obtained by 

 beating, and what insects he met with were late in appear- 

 ance. Larvae on heath were plentiful, especially Agyotis 

 agathina, and earlier in the year Scodiona bclgiaria larvae had
