212 THE ENTOMOLOGIST. 
Several of the moths I found difficult to refer with any 
degree of certainty to either(?) species. In the autumn 
many of the young larve had developed markings like those 
of Z. Trifolii. This spring (having failed in my two previous 
attempts) I put the Z. Meliloti, of which about thirty out of 
three hundred survived the winter, into a greenhouse, and in 
the result got nine pupez; the major portion of the twenty- 
one others fed and grew with their companions for a while, 
and then hybernated again. Of the nine pupe six have now 
hatched, and produced full-coloured specimens of the small 
Z. Trifolii that 1 found in company with Z. Meliloti last year. 
The following questions suggest themselves:—(1) Is the 
Z. Meliloti of the New Forest a separate species or a dwarfed 
form of Z. Trifolii? (2) If a dwarfed form, did the additional 
greenhouse heat aid in developing it? (3) If a separate 
species, can the specimens I bred from have paired with 
Z. Trifolii previously? I may add that 1 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 speci- 
mens 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, in a 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.
