ever seen. He added that he had made many attempts to 
cross Zygena meliloti with jfilipendula, lonicere, and trifolii, 
and the hybrids between the last two, with the result of 
obtaining two pairings between 7. meliloti and filipendule, 
and one between the former and a hybrid male. In all cases 
the eggs failed to hatch. 
Mr. Barrett said that this seemed to suggest that Zygena 
lonicera, Z. trifolii, and Z. filipendule were one species. 
Mr. Tutt remarked that in a certain field in Kent, some ten 
years ago, what is known as the small form of Zygena trifolit 
was taken very abundantly during the first week in June. 
These specimens were very characteristic, many of them being 
strikingly blotched; but occasionally an odd specimen was 
taken with six instead of five spots on the fore wings. 
The species afterwards got very rare, and of the specimens 
captured, at least 50 per cent. had six spots, although still 
retaining the small size and general characters of the old 
five-spotted form. Two of the five-spotted specimens captured 
in 1892 had their fore wings taken off and their bodies 
forwarded to Mr. Pierce, of Liverpool, who examined the 
genital organs and returned them as undoubted /ilipendule. 
Knowing their history completely, Mr. Tutt felt satisfied that 
these represented the development of a race of six-spotted 
trifolii. There were, he said, two suggestions open : first, 
that we have a separate species occurring in late May and 
early June, distinct from both jitlipendule and trifolit, which 
(like some of the continental species) may be either five- or 
six-spotted ; secondly, that Zygena filipendule and Z. trifolii, 
although distinct enough in most localities, are in others in 
such a transition state that they have the inherent ability to 
change from one form to the other under certain conditions. 
The ease with which Mr. Fletcher has hybridised the species 
seemed to point to the latter as a more probable conclusion. 
He added that both typical lonicere and jilipendule occur in 
the immediate neighbourhood, but that the former rarely 
appears until the form described above is well over, whilst the 
latter is always a week or two behind lonicere.
