of depositing eggs in their tissues, or that the victims were 

 unnoticed by those who turned up the soil. Mr. Priske said 

 that Mr. Claude Morley had contributed a paper on the 

 Hymenoptera parasitic upon Coleoptera to the " Proceedings 

 of the Entomological Society of London." 



Mr. Robert Adkin exhibited a series of Endromh versicolor, 

 reared from Aviemore ova ; the larvae were fed up during 

 the summer of igo8, and the imagines shown represented 

 about half the brood ; the remainder were still in pupae, and 

 no doubt would not emerge until the spring of 1910. 



He also exhibited full-fed larvae of Nyssia zonaria, reared 

 from Wallasey ova, and stated that during their earlier 

 stages they fed indiscriminately on leaves of rose, birch, and 

 sallow, but as soon as knotgrass was obtainable they 

 appeared to prefer it, and, indeed, to thrive upon it. They 

 had now, with the exception of some half-dozen individuals, 

 all pupated. Referring to the ova, he said that he received 

 two batches from Mr. T. A. Clarke, of Liverpool, who called 

 his attention to their variation in colour. One batch was 

 found wild, and was deposited under the sheath of a dead 

 grass stem ; these eggs were of a deep green colour, which 

 hue they retained until the change to a lead colour just 

 before hatching. The other batch was deposited in con- 

 finement, in a split sweet-pea stem ; the eggs when re- 

 ceived had been only recently deposited, and were of a 

 pale yellow colour, but gradually became darker yellow, and 

 until they had become almost orange, just before the final 

 change to lead-colour, at no time did they assume a green 

 coloration like those of the other batch. In neither case 

 did they appear to harmonize with the substance on which 

 they were deposited ; indeed, being so completely hidden 

 from sight it did not appear that harmonizing with their 

 surroundings would be of any advantage to the species. 



Butterflies Attacked by Birds. — Mr. R. Adkin related 

 the following incident : " While at breakfast this morning 

 my attention was attracted by a continuous tapping on the 

 roof of a small conservatory that adjoins my breakfast -room, 

 and on looking out to ascertain the cause I discovered a 

 white butterfiy {Pieris hrassicce) fluttering along the inside of 

 the roof, and on the outside three sparrows were fluttering 

 about just over it, the noise being caused by their beaks 

 beating upon the glass in a frantic but ineffectual attempt to 

 reach their prey. They continued to follow and strike at 

 the butterfly so long as it fluttered under the glass, but so 

 soon as it passed under the wooden sill of the roof, and was
