fimbriana, 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 splendidulana, and that 

 argyrana did not appear till a mouth later.

ADDITIONAL NOTICE EESPECTING THE MAPLE-MINING SAW-FLY 

 (PEYLLOTOMA AUERISJ. 



BT 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 Hymenoftera. 

 However, on looking over Kaltenbaeh's paper on the plant-feeding 

 G-erman insects ("Die deutschen Phytophagen aus der Klasse der 

 Insecten") published in the " Verhandlungen des naturforsclienden 

 Vereins des preussichen Blieinlandes" 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 — Phyllotojna 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 antennae 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 just 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- 

 baeh's paper in a separate form m the well-known library of a colleague.
