Exhibitions. 
Mr. Edward Saunders exhibited a series of species of Australian 
Buprestide, illustrating the sexual differences existing in these insects, the 
male in all cases being much smaller than the female. 
Mr. F. Smith exhibited a large collection of Hymenoptera, chiefly 
Aculeata, sent from Japan by Mr. G. Lewis. The collection was strikingly 
European in its aspect, and, with the exception of one genus of ants, all 
the genera were European. The genera represented were Camponotus, 
Tapinoma, Polyrhachis, Ponera, Formica, Tiphia (four species), Mutilla 
(one species only), Scolia, Pompilus (allied to a North-American form), 
Ammophila, Sphex, Bembex, Vespa, Sphecodes, Nomada, Ccelioxys and 
Halictus. Some of the species appeared to be identical with European 
forms, such as Camponotus pubescens and ligniperdus and Sphex argentata. 
Among the Tenthredinide the genus Hylotoma was represented by six 
species, all probably new; and there was also a species of Sirex extremely 
like S. gigas, but differimg from it in the constricted base of the abdomen. 
The collection was sent from Hiogo. 
Mr. Verrall exhibited a specimen of Syrphus lasiophthalmus with a 
peculiar malformation of two of the tibize, those members appearing as if 
they had been broken and badly united afterwards. He considered it was 
due to an injury received just after the insect had emerged from the 
puparium, when the parts were soft. 
- Mr. M‘Lachlan remarked that he had.observed an analogous malformation 
in a sawfly (Hylotoma fasciata). See Proc. Ent. Soc. 1867, p. xcix. 
Mr. Stainton exhibited an aspen-leaf sent by Lord Walsingham from 
Fort Klamath, Oregon, pierced by a multitude of small oval holes, each 
indicating the place where a small mining Micro-Lepidopterous larva of the 
genus Aspidisca had cut out its case when full fed. He had figured a smaller 
leaf so attacked on the cover of the ‘ Entomologist’s Annual’ for 1872. He 
also exhibited living and dead examples of the perfect insect bred from 
cases sent to him by post by Lord Walsingham. 
Papers read. 
Mr. Edward Saunders read “ Descriptions of twenty new species of 
Buprestide.” 
Mr. H. W. Bates read a memoir “On the Longicorn Coleoptera of 
Chontales, Nicaragua,” chiefly drawn up from materials collected by Mr. 
Thomas Belt near the mining village of Santo Domingo, in lat. 12° 16’ N., 
long. 84° 59’ W., nearly midway between the Atlantic and Pacific Oceans, 
in the forest region of the lower levels. Of the 242 species enumerated 
133 were peculiar to Chontales, 38 were found also in Mexico, 5 also in the 
West Indian Islands, 5 also in the United States, 24 also in New Granada 
and Venezuela, 22 also in the Amazon Region, 10 also in South Brazil, and
