Exhibitions, Sc. 



Mr. McLachlan (on behalf of Mr. W. Denison Roebuck, of Leeds) ex- 

 hibited some locusts, a swarm of which had been observed to pass over 

 Yorkshire during last autumn. He had examined the specimens carefully, 

 and had compared them with the descriptions of the two species which 

 occasionally visited this country, viz., Pachytylus migratorius and P. cine- 

 rascens ; and he had come to the conclusion that the specimens belonged to 

 P. cinerascens, which he remarked was supposed to breed in some parts of 

 the north of Europe, and therefore might be expected more frequently in 

 this country. 



Mr. W. C. Boyd exhibited living larvse of Brachycentrus subnubilus, in 

 their quadrilateral cases, reared from the eggs. They were of much larger 

 size than those previously exhibited by him at the November meeting in 

 1873, being more than half an inch long. 



Mr. S. Stevens (on behalf of Mr. Edwin Birchall) exhibited a specimen 

 of Cirrhcedia xerampelina, var. unicolor, Agrotis lucernea, var. latens, and 

 what appeared to be a small var. of Zygaena filipendulae, with the pupa-case 

 and cocoon. They were all taken by Mr. Birchall in the Isle of Man, 



Mr. Meldola referred to a request made by Mr. Riley at the meeting in 

 July, 1875, that entomologists would supply him with the cocoons of the 

 parasite, Microgaster glomeratus, which were much wanted in America to 

 destroy the numerous specimens of Pieris rapse which had been imported 

 into that country. Mr. McLachlan had at a subsequent meeting stated 

 that M. glomeratus was parasitic on P. brassicae, but doubted if it ever 

 attacked P. rapse, and Mr. Meldola now exhibited the insects he had found 

 parasitic on these two species — that on P. rapoe being Pteromalus imbutus, 

 Waltl. (one of the Chalcididse), while on P. Brassicse he had observed 

 Microgaster glomeratus and a Dipterous species, Tachina augusta. Speci- 

 mens of all of them were exhibited. INIr. E. A. Fitch remarked that Van 

 Vollenhoven had obtained Pimpla examinator from P. Napi. 



Mr. Smith stated that he had received a nest of Osmia muraria, sent 

 to him from Switzerland. The cells were empty, the Osmise having taken
