2 French quercus, differ very slightly, if at all, from typical English 
quercus. My $ sicula with 2 French quercus have adult colora¬ 
tion and fur, but are not fully grown. They are very similar to 
spartii. Last year, Mr. Warburg crossed French quercus with 
spartii, and the larvie of this cross, instead of showing transitional 
forms, divided into two batches, one being exactly similar to 
typical larvas of spartii and the other to typical French quercus. I 
am quite unable to give any explanation of this fact. None of the 
other crosses have shown the slightest tendency in this direction. 
The pupae resulting from these different forms of hybrid spartii- 
quercus larvae were kept separate, and I crossed and paired the moths 
in all possible ways. Unfortunately, there is a large amount of 
disease among the larvae this year, and I have lost most of the larvae 
of these pairings, but the tendency of the few larvae which reached 
adult coloration, was to follow the parental form, where the parents 
had the same coloured larvae. When crossed again with the species 
the results were different. A moth bred from the white-haired hybrid 
larvae, crossed with spartii, produced larvae of spartii form ; but I 
only have four or five larvae living of this cross, the bulk dying 
before obtaining adult colours. On the other hand, a moth from 
brown-haired hybrid larvae, crossed with French quercus , produced part 
brown-haired and part white-haired larvae. I have six living larvae 
of this cross, three of each colour. The only living larva that I 
have of .a pairing between the brown-haired hybrid larvae with the 
white-haired hybrid larvae, is white-haired. These last results are 
based on far too meagre data to he of any scientific importance; 
but they are, I think, not without interest, as showing what uncer¬ 
tain results attend the crossing of varieties or sub-species. Enodia 
hyperanthus, with pale undersides. —Mr. Prout: A long series of 
undersides of Enoclia hyperanthus, sent by Mr. G. B. Routledge, 
from the Carlisle district, considerably paler than the southern form, 
and a few specimens approaching the extreme ab. arete. Rare 
Diptera and Coleoptera. —Mr. Claude Morley, exhibiting as a 
visitor, A emoraea quadraticornis, Meade, unique, taken at Ips¬ 
wich in 1893, described in Ent. Mo. Mag., July, 1894 ; two Phorocera 
incerta, Meade, new to science, taken not uncommonly on oak 
trunks near Ipswich in 1897, described in Ent. Mo. Mag., Oct., 1897; 
two Xysta ( Phasia ) cana, Mgr., new to Britain—a doubtful specimen 
taken in 1893, and an authentic one in May, 1896, both at Ipswich; 
two Microdon mutabilis, L., very rare indeed — two specimens in the 
New Forest in May, 1895; these are described in Mr. Verrall’s forth¬ 
coming work on the British Syrphidae ; one Nomada guttulata, Schk., 
the second British specimen (the first in Mr. Saunders’ collection 
having no locality attached), taken at Ipswich, May, 1897; one
