Mr. Briggs exhibited bred specimens of Zygena Meliloti, accompanying 
them with the following remarks :— 
“Tn 1872 and 1873 I reared young larve of Z. Meliloti from the New 
Forest, up to and through hybernation, but they died in the following 
springs; and these larve, from the minuteness of the markings on the 
ground colour, showed a great distinction from the young larve of Z. Tri- 
folii of the same age. 
« Last year (1874) I found small specimens of Z. Trifolii in company 
with Z. Meliloti. I therefore took especial care that the eggs I reared were 
from four typical pairs of (the New Forest) Z. Meliloti, found in copula; 
the eggs were (in all four cases) larger than the eggs of Z. Trifolii—a 
peculiarity I had remarked in previous years. 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 pups ; the major portion of the 
twenty-one others fed and grew with their companions for a while and then 
hybernated again. Of the nine pup@ six have now hatched and produced 
full coloured specimens of the small Z. Trifolii that I 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?
