Westw., Hobarton ; an apparently nondescript species of Lissotes from Victoria, to 
which Dr. Howitt applied the trivial name ‘ furcicornis”; anew species of Cera- 
tognathus, from Hobarton, for which Dr. Howitt proposed the specific title 
“ setiger’’; and Dorcadida bilocularis, White, from Hobarton. 
Mr. Stainton exhibited the specimen of Stathmopoda? Guerinii, which he had 
received from M. Guérin-Meéneville in 1857, with the intimation that it was “ éclose 
dune grande galle sur le pistacier,” and which till last month had remained unique. 
Towards the end of September Dr, Staudinger, who had gone on a collecting expedi- 
tion to Celles-les- Bains (Department of Ardéche) sent over some Nepticulized leaves of 
Pistacia terebinthus, and on the 28th of September Mr. Stainton wrote suggesting a 
search for the gall-feeding Stathmopoda. On the 2nd October Dr. Staudinger wrote 
in reply :—“ Many thanks for the notice respecting Stathmopoda ? Guerinii, of which 
I herewith send you five larve. I had long noticed the galls on the Pistacia (often 
very large), and had opened some, but there were thousands of Aphides within and a 
quantity of white dust, so that it seemed an unprofitable occupation. To-day, 
however, I have renewed my search with fresh energy, though it is very dirty work, as 
there is besides a resinous secretion. I found, however, two sorts of larvye in them, 
generally living amongst hundreds of Aphides, on which they probably feed, since I 
did not find the inner parts of the galls eaten; the larger larva belongs to the 
Phycidez, and the smaller white larva is that of Stathmopoda? Guerinii; of this 
latter I also found pupe, and in one firmly closed gall a fresh specimen of the perfect 
insect. There are three kinds of galls on the Pistacia ; the largest is at the ends of the 
shoots, elongate and curved, but they vary much in form and size; one which I found 
was nearly a foot in length. It was only in this kind of gall that I found the larve of 
the S. Guerinii, generally in the smaller speciinens. The larva makes a firm case of 
grains of excrement, which is attached to the inside of the gall; generally there is an 
opening made, through which the perfect insect may escape, yet I found some galls in 
which this was not the case, and in which the moth would only come out in the 
interior of the gall. I imagine that the Aphides are the originators of the galls, in 
which subsequently the moths lay their eggs ; but on what do the larve feed?” Ten 
days later Dr. Staudinger had been able to add some further details :—‘“* The Aphides 
originate the galls, then the moths deposit their eggs on them: the larve feed on the 
inner walls of the galls: the larve of Stathmopoda Guerinii sometimes leave the open 
galls and creep to some distance to undergo their change to the pupa state; but more 
frequently they remain in the galls. The pupe stick sometimes half out of the, galls, 
and then retreat back again; they do this especially when there has been heavy rain, 
and the water has penetratad the galls.” A beautifully coloured drawing, by Miss 
Wing, of the gall and larva was also exhibited. 
Mr. Stainton also stated that he had lately received from Herr Hofmann, of 
Ratisbon, a larva in the berries of the alder, which was presumed to be that of Stath- 
mopoda pedella; of this he exhibited a figure, and remarked that it was with the 
greatest difficulty that this larva could be got out of the alder-berries alive, for it was 
often in a burrow close to the central core, and owing to the hardness of the berry it 
was almost impossible to avoid the destruction of the larva. 
Mr. Stainton exhibited a collection of Tineina from Syria and Asia Minor, which, 
Heir Lederer, of Vienna, had liberally sent over to enable him to work out the 
collection of insects made by Mr, Pickard-Cambridge in Palestine. Several of these
