(2) If a dwarfed form, did the additional greenhouse heat aid in de- 
veloping it ? 
(3). If a separate species, can the specimens I bred from have paired 
with Z. Trifolii previously ? 
*‘T may add that I have compared M. Boisduval’s description of the 
continental Z. Meliloti with the New Forest insect, and they do not agree 
in several particulars ; and I have inspected the British Museum specimens 
of continental Z. Meliloti, and they also differ from the New Forest insect— 
especially in the form of the wings. The fact of the hybernation of the 
larva for a second year seems common. I have found it with Z. Trifolii 
and Z. Meliloti during the last three years, and it has been recorded of 
Z. Lonicere. Out of one hundred larve of Z. Trifolii that survived last 
winter I obtained twenty-five pupz (most of which are out); about twenty 
died, and the rest resumed hybernation, in the first week in June, ina 
greenhouse, the average daily temperature of which is 75°, and are now 
hybernating and apparently healthy.” 
Mr. M‘Lachlan remarked that the insects of the genus hybridized very 
freely, and alluded to the possibility of their pairing more than once. 
Mr. W. A. Lewis had noticed that Z. Meliloti was by far the commonest 
insect in the part of the New Forest which forms its head quarters, and that, 
as it appeared to have been only discovered there of late years, it might be 
a stunted form which had been developed recently. Mr. Weir said that he 
had taken the insect twenty years ago in Tilgate Forest. 
The Rey. A. E. Eaton exhibited the insects recently taken by him in 
Kerguelen’s Island. There were about a dozen belonging to the Cole- 
optera, Lepidoptera and Diptera, besides some specimens of bird-lice and 
fleas. 
Mr. Briggs exhibited a specimen of Halias prasinana, which when taken 
was heard to squeak very distinctly, and at the same time a slender filament 
issuing from beneath the abdomen was observed to be in rapid motion, and 
two small spiracles close to the filament were distinctly dilated. 
The President called attention to a living larva which he had that morning 
extracted from the body of a stylopized female of Andrena Trimmerana, taken 
at Reigate on the 4th of June,—this larva having a long attenuated telescopic 
process at the anterior extremity, and two piceous reniform appendages 
behind, like that of Conops, which he had frequently reared from Pompilus, 
Sphex and Odynerus, as described by him in our ‘ Transactions’ (vol. iv., 
ser. 2, 1858, pl. 28). These larvee had also been met with in Bombus by 
Latreille, Dufour and others, as well as in Osmia, but not in Andrena, which 
moreover had been doubly victimized in the present instance, having the 
greater portion of the abdomen preoccupied by. another invader, and 
thriving in spite of this and of the Conops larva subsequently lodged at 
the base.
