Jtmhriana, but it is in reality far more closely allied to Coccyx argyrana, 
so much so, indeed, that at first I rather inclined to consider it a small 
dark narrow-winged variety of it. 
My friend Mr. Bond, however, has all along asserted it to be a 
distinct species, and now that his opinion has been confirmed by that 
of Dr. Staudinger, with whom I have had some correspondence on the 
subject, my doubts have given way, and I am induced to furnish it 
with a name. 
It may be distinguished from argyrana, which is the only insect 
with which it can possibly be confounded, firstly, by the fore-wings 
being narrower and darker, the dorsal patch being inconspicuous ; and 
secondly, by the hind- wings of the male being pretty uniformly dark 
and without the pale base, such as is noticed in argyrana. 
Mr. Meek informs me that he captured these- three examples by 
beating undergrowth at West Wickham, towards the end of March, 1866, 
that its habits were similar to those of Coccyx sijlendidulana, and that 
argyrana did not appear till a month later.

ADDITIONAL NOTICE EESPECTING THE MAPLE-MINING SAW-FLY 
(PHYLLOTOMA AUERISJ. 
BY R. m'lACHLAN, F.L.S. 
At page 104 of this volume I was induced to describe the above- 
mentioned saw-fly as new, not having been able to find anything like 
it mentioned in any work or papers devoted to European Hymenojjtera. 
However, on looking over Kaltenbach's paper on the plant-feeding 
German insects ("Die deutschen Phytophagen aus der Klasse der 
Insecten") published in the " VerJia7uUungen des naturforschenden 
Vereins des preussichen HJieinlandes,^' vol. 13, I find, at page 257, No. 
40, what is undoubtedly the same species, described by Herr Kaltenbach 
under the same name as that which I applied to it — Phyllotoma aceris. 
Hence this is one of those rare instances in which ignorance of a pre- 
vious description has not created a synonym. Herr Kaltenbach describes 
the antennas as " 12- jointed," whereas I can only find 11 in my few 
specimens, but the number of joints is variable in other species of the 
genus. Also, from his description of the habits of the larva, he would 
seem to have observed it jiist before it detached the circular case, which 
latter he describes as a cocoon. The " Verhandlungen'" referred to is 
difiicult to obtain access to in England, but I fortunately found Kalten- 
bach's paper in a separate form in the well-known library of a colleague.
