strange looking Porata with the central spots on both wings almost 
absent, such as I once bred from Wimbledon common, but these have 
all the appearance of a local race rather than a cross with Punctciria, 
and in like manner we have that dark form of Pendularia from Market 
Drayton, which, of course, is but a local form. I think I may be safe 
in saying that seldom do genera retain so many points of affinity 
as in this group. It occasionally happens that we see traits of 
character in species that have a somewhat wide separation; for 
instance the larvte of Smaragdaria have a peculiar habit of moving the 
head to and fro while holding on by the claspers and the same habit is 
to be seen in the larva; of Thy mi aria. I might mention incidentally 
that the habit just referred to is most useful to the collector when the 
larvae are in that frame of mind. I was once on the Essex marshes 
with the late J. A. Cooper when we went over some saltings to pick 
up a bird he had just shot, and we came upon a colony of Smaragdaria 
larvae with all their heads moving and showing up most conspicuously, 
and before we left the spot we had picked up over 100 larvae. I could 
never make out what induced the larvae to move, as I have been over 
the marshes many times since, but have always had to work hard to 
find them. Whilst touching on the affinity of species perhaps I may 
be permitted to criticise the severance of Bondii and Arcuosa, which is 
usually the case now in most lists. What could have induced the 
authorities to have placed Arcuosa with Strigilis, Literosa, and others, 
I certainly fail to see. The general appearance of Arcuosa and Bondii 
are similar, both possessing an unusually slender thorax, quite unlike 
Strigilis or even the more slender Furuncnla; the flight of Arcuosa is 
different, having more the weakly flight of a Geometer, whereas the 
former species absolutely dash about. And above all there is a strong 
tendency to grease in Arcuosa which none of the Miana are troubled 
with. This fact in itself goes a long way to my mind, for although 
there are several widely different genera that always grease, I cannot 
call to mind another case of one species in a genera possessing this 
most annoying tendency and the next of kin being entirely free from 
it. I confess I know nothing of the larvae of Arcuosa, but’ the fact of 
its being an internal feeder would not go for much one way or the 
other. It is a striking fact that insects whose larvte are internal 
feeders are generally most liable to grease, and some of those feeding 
underground are equally susceptible, as in the case of the genus 
Hepialus. But in the genera Miana and Aparnea, where many of them 
feed in the stems of grass, they are usually free from grease. Before 
concluding it now r only remains for me to heartily thank all the 
officers of the Society for the manner in which their several duties 
have been carried out. In some cases the work entailed is very- 
considerable, more particularly so with our Secretaries, Mr. S. J. Bell 
and Mr. E. Harris, and our Treasurer, Mr. C. P. Pickett, and I am 
sure I am not only r expressing my own feelings, but those of the 
members at large, when I tender our sincere thanks to those gentlemen, 
and at the same time I take the opportunity of congratulating the 
members on retaining the services of the whole of the Officers of the 
Society. 
In conclusion I have again to thank you, gentlemen, for once 
more electing me as your President, and although it might have been 
more beneficial to the Society if a new President had been elected, I
