from thence into the spirit, and this time dry it with its back 
upwards on the glass slide. It may then be removed quite stiff 
and well-set, and mounted on a piece of thin card with only 
a slight dot of gum under the thorax. 
Though apparently troublesome, the process comes easy 
enough after a little practice. I have often mounted thirty or 
forty specimens in a couple of hours, and have succeeded in the 
smallest Chalcids, and even the most difficult and unruly 
Cynipide. The reason of adding the sugar to the gum is to 
make it more quickly soluble in water, and it also dries quicker 
and firmer. Great care should be taken to wash off the gum 
thoroughly in the last washing, as otherwise the wings might 
stick to the glass slide. I have tried the same plan most success- 
fully with the Tenthridinide, and also with Coleoptera, and even 
kill bees in the same manner. It is certainly the best way 
of obtaining perfect relaxation after death.

THE TORTRICES OF SURREY, KENT, AND SUSSEX. 
By Wa.rer P. Wesron. 
(Continued from p. 9.) 
Antithesia salicana, Gn.— Common among the larger kinds of 
sallow, and occasionally to be met with on the trunks of poplars. 
It flies boldly and quickly at dusk in June and the early part of 
July, but is one of the species that does not travel quietly when 
boxed. It may also be taken plentifully in the daytime at rest 
on the stems of pollard sallows, and willows. 
Spilonota ocellana, Fab.—Common everywhere, and particu- 
larly so among whitethorn hedges. The larva appears an ubiquitous 
feeder, for, besides apple and whitethorn, it affects shoots of alder 
(Alnus glutinosa), and occasionally sea-spurge (Huphorbia paralias), 
and the common dock (Rumex obtusifolius). S. hippophaana, 
which derived its name from the larva feeding in united shoots of 
sea-buckthorn (Hippophaé rhamnoides), though ranking for a 
time as a species, must be considered but a form of this insect. 
When alive the whitish portions of the wing certainly appear 
lighter and clearer than in S. ocellana ; but on rearing a long series 
no difference can be perceived in the two forms, both of which
