66 THE ZOOLOGIST. 
Election of Members. 
M. Eduard Gruhe, Director of the Zoological Collection in the University 
of Breslau, and Dr. Katter, of Putbus, in the Island of Riigen, were balloted 
for and elected Foreign Members. Lord Dormer, formerly a Subscriber to 
the Society, was re-elected a Subscriber. 
Exhibitions, &c. 
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 larvee 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 Cirrheedia xerampelina, var. unicolor, Agrotis Lucernea, var. latens, and 
what appeared to be a small var. of Zygwna filipendule, 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 rapee which had been imported 
into that country. Mr. McLachlan had at a subsequent meeting stated 
that M. glomeratus was parasitic on P. brassicew, but doubted if it ever 
attacked P. rape, and Mr. Meldola now exhibited the insects he had found 
parasitic on these two species—that on P. rape being Pteromalus imbutus, 
Waltl. (one of the Chalcidide), while on P. Brassice he had observed 
Microgaster glomeratus and a Dipterous species, 'Tachina angusta. Speci- 
mens of all of them were exhibited. Mr. 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 Osmie having taken 
their departure, but one closed cell was observed to contain a yellow larva, 
which ultimately proved to be that of a beetle belonging to the Cleride, 
Trichodes alvearius.
