DESCRIPTION OF THE LARVA OF ARGYRESTHIA ATMORIELLA, 



Bankes. 

 BY THE RIGHT HON. LORD WALSINGHAM, M.A., LL.D., F.R.S., &c. 



Smooth, shining, pale greenish yellow ; head black ; prothoracic plates trian - 

 gular, with the apex pointing outwards, the anterior half pale chitinous brownish, 

 the posterior half blackish ; tlioracic legs Tery short, with three black annulations, 

 abdominal and anal legs concolorous with the body ; anal plate very small, blackish. 

 Long., 5 mm. (23.11), fi mm. (3 IV). Merton, excl. 19.V.1899. 



Mining the terminal twigs of the branches of Pinus larix. In 

 the spring when the leaf-buds of the larch begin to expand the leading 

 twig for about three inches develops no leaves, and on examination 

 will be found to be hollowed out and filled with frass from the tip 

 downwards as far aa the last well-developed bud. The larva is ex- 

 ceptionally found in one of the side shoots, but almost invariably 

 attacks the leading shoot. The presence of empty pupa-cases in old 

 mines, where a hole is always found at the side of the shoot (which 

 is often broken off at this weakened point), seems to indicate that 

 the habit of the larva is to pupate in the mined shoot ; a specimen 

 now bred confirms this impression. Pupa pale ochreous brown. 



Long., 45 mm.

CEUTHORRHYNCHUS QUERCETI, aTLL. : AN ADDITION TO THE 

 LIST OF BRITISH RHYNCHOPHORA. 



BY G. C. CHAMPION, F.Z.S. 



Mr. J. Edwards has recently called my attention to the fact that 

 there were in Norfolk two distinct species passing under the name 

 CeutJwrrhynchidius terminatus, Herbst — one with a 7-jointed funiculus, 

 living in marshy places, the other with a 6-jointed funiculus, living 

 in dry places. The marsh insect proves on examination to be referable 

 to CeutliorrJiynclius querceti., Gryll., not hitherto recorded as British ; 

 the other is CeiUhorrliynchidius terminatus., Herbst. 



Of C. querceti I have now seen several specimens, all from Horning 

 Fen : two in the collection of Mr. E. Saunders, captured about thirty 

 years ago by the late J. A. Brewer, and others taken a few years back 

 by Mr, Edwards and Mr. Elliman. Mr. Elliman's examples (4) were 

 found on July 4th, 1895, upon a solitary cruciferous plant, ? Raphanus 

 raphanistrum. 



Thomson (Skand. Col., vii, p. 270) describes the species as follows : 



" Breviter ovatus, leviter convexus, supra subopacus, griseo-pubescens, suturse
