form ; the elytra linear-elongate ; these differences however are 

 very slight when compared with specimens of equal magnitude, 

 and require a practised eye to catch them. 



Frequently found upon aquatic plants, in ponds and ditches, 

 in June.

Gyllenhal was undoubtedly correct in the subsequent change 

 of his opinion as to the specific identity of this insect, by elabo- 

 rately describing it under the first name*; it evidently differs in 

 its general form from Er. Nereis, and the rostrum is decidedly 

 stouter and more distinctly rugose ; the thorax more deeply and 

 closely punctured, with the punctures confluent ; the elytra pro- 

 foundly crenate-striate, especially on the interior towards the 

 suture, clouded with testaceous and piceous black ; and clothed 

 with flavescent scales variegated with fuscous. 



British specimens were identified by Schonherr as Er. scir- 

 rhosus. 



I purchased five specimens from a dealer at York of the name 

 of Chapman, who obtained them with a collection of British in- 

 sects taken in the neighbourhood of Cambridge. Mr. S. Stevens 

 has a specimen taken by Mr. Bond near Kingsbury ; these are 

 all that I have seen of this insect.

1. Notaris acridulits, Linn., et auct. alior. 

 A very common and well-known species. 



2. N. jEthiops, Fab., Gyll., Steph. Man., Curt., Schonh. 



Foreign specimens in the collection of Mr. Kirby from Gyl- 

 lenhal, and others in my possession from Schonherr, confirm the 

 name of this very distinct insect. 



First discovered in Yorkshire by the late Rev. G. T. Rudd, 

 who kindly furnished my cabinet with specimens. 



3. N. himaculatus, Fab., Gyll., Steph., Schonh. 

 A rare and very distinct insect.

Elongate-ovate, piceous, sparingly clothed with elliptical-lan- 

 ceolate pale scales. Head small, punctulated ; eyes subdepressed ; 

 rostrum rather longer than the head and thorax, moderately 

 curved, black, shining, carinated above, distinctly striated and
