met wiih a peculiar odour in Cyuips lignicola, as well as in an undetermined species 

 of Cynips bred from a pea-gall on llie under side of oak-leaves. When the meeting 

 was over Mr. Boyd kindly handed me some galls of Biorhiza aplcra, Fab., from 

 which I have since bred a number of females, all of which on being handled alive 

 emiiled a powerful scent, like that of a very ripe pear. I have also detected a similar 

 but fainter odour in Cynips folii, Linn. If we turn to other groups of Hyniciu.ptcra, 

 the pungent quality of many of the Formicida? will of course occur to every reader; 

 and as regards Crabronidae, Mr. T. J. Bold has long ago recorded, in the ' Zoologist,' 

 of Crabro cetratus of Shiukard, that when he pinned the latter they "emitted a 

 powerful perfume, somewh^it resembling that of roses." Professed hymenopterists will 

 no doubt be able to add numerous instances in other groups, particularly in the

Exhibitions, ^-c. 



Prof Westwood exhibited drawings and dissections of some Hymenoptera pos- 

 sessing extraordinary structural peculiarities: they were principally Chalcididse, of the 

 genera Prionopelma and Metapdma (see Proc. Zool. Soc. 1835). 



Mr. F. Smith exhibited a mass of earth-cells formed by a species of Halictus, 

 found by Mr. J. K. Lord near Cairo. The bee burrowed into the ground to a depth 

 of about twelve inches, and the cells were then formed, close together, and all round 

 the shaft or tunnel, the entrance to each cell being from the central shaft. Mr. Lord 

 described the bee as making a tubular entrance to the nest, probably of the material 

 which was thrown out in the excavation of the vertical shaft, but the construction was 

 too biitlle or fragile for transport. Mr. Smitii remarked tliat this tubular entrance was
