166 Mr. J. Walton on the British species of 



In P. elatior (J acq.) the capsule is linear-oblong, as long as, 

 or even slightly longer than, the calyx, the seeds forming round 

 flattened discs, their surface rotundo-papillose, the style glabrous, 

 the ovato-lanceolate teeth of the calyx curved outwards.

XVII. — Notes, fyc. on the genera of Insects Erirhinus, Notaris, 

 and Procas ; with descriptions of two new species. By John 

 Walton, F.L.S. 



Fam. CURCULIONnm 



Genus Erirhinus, Schonh., Steph., Curt. 



It will be useful to remark, that the females of this genus have 

 the rostrum long, slender, somewhat smooth, shining, minutely 

 punctured in rows, and indistinctly striated ; the males have it 

 shorter, rather thicker, less shining, rugose-punctate, distinctly 

 striated, and the antennae placed nearer the apex. 



1. Erirhinus Festucce, Herbst, Gyll., Steph., Schonh. 



There are two foreign specimens of this insect labelled ( Fes- 

 tucce * in the collection of Mr. Kirby from Gyllenhal, and I pos- 

 sess a British specimen returned to me by Schonherr with the 

 same name ; it is accurately described by Gyllenhal and Stephens, 

 and chiefly differs from Er. Nereis in being much larger (length 

 2^ — 3 lines) ; specimens however sometimes occur of the same 

 size as that species, which are consequently extremely difficult to 

 distinguish. It is recorded to be rare in England, but its rarity 

 appears to arise from its habitat being strictly local ; I believe a 

 British specimen did not exist in any collection until I discovered 

 its e metropolis. 3 



I have found it plentifully by brushing the salt-marsh club- 

 rush (Scirpus maritimus) on both sides of the Thames, about low- 

 water mark, between Blackwall and Woolwich, in July ; and also 

 near Lyndhurst on aquatic plants. " Ditches below Gravesend,"

2. E. Nereis, Payk., Gyll., Steph., Schonh. 



— inquisitor, Steph. Illustr. 



— lunula et Arundineti, Kirb. MSS. 



I have British specimens returned to me from Schonherr as 

 Er. Nereis. It is generally about half the size of the preceding 

 insect (length 1- — 2^ lines), and also differs in having the 

 rostrum and antennse shorter, with the articulations of the 

 latter also shorter, rather stouter, and somewhat different in
