3. H, Polygoni, Linn. sec. ej. Mus., Fab., Gyll., Steph., Schonh, 



— arator var., Linn. sec. ej. Mus,, Marsh., Steph. 111., Kirb. MSS. 



— canescens var. et VicieewTiY., Steph. sec. ej. Mus. 



— picicornis var., Steph. sec. ej. Man. 



The male has the anterior tibia acutely dentate in the middle 

 within. Of Rhxjnch. Vicim of Gyll. I have never seen an indi- 

 genous specimen agreeing with the two foreign insects in the col- 

 lection of Mr. Kirby. 



Rather common ; found in damp meadows near Lyndhurst, 

 Battersea Fields, Arundel, Yorkshire, &c. in June. 



4. H. Polluxy Fab., Xxyll., Germ., Schonh. 



— alternans var., Steph. III. 



— Kunzii var., Steph. Man., non Schonh. 



— pcdustris (Leach MSS.), Steph. 



— Julinii (Sahib.), Schonh., var. sec. Germ. 



— biteeniatus, Kirb. MSS. 



I sent many specimens of this insect to Germar, who has sub- 

 divided the varieties as follows : — 



a. " With gray scales upon the elytra, and with small square 

 spots arranged in rows — the true Phyt. Pollux, auctor. 



b. " With brown scales ; the elytra checkered with black, and 

 with two broad, gray, black checkered longitudinal lines — 

 Hypera palustris of Steph. 



c. " Brown or black, with three gray unspotted longitudinal lines 

 upon each elytron — Hypera alternans of Steph. ; Kunzii, Steph. 

 (but not Schonh.) ; Julinii, Sahib.* " 



Identified as Rh, Pollux of Gyll. by a foreign specimen in the 

 collection of Mr. Kirby. I possess foreign specimens from Ger- 

 mar of Hy. Kunzii, which is undoubtedly a very distinct insect, 

 and unknown as British. There is a fine series of varieties of 

 Rh. palustris of Leach in the British Museum ; also Mr. S. Ste- 

 vens and myself have a long series of this insect. 



Occasionally found on grassy banks, at the sides of ponds and 

 ditches, in marshy placesj but not plentifully, in June, 



5. H. Rumicis, Linn. sec. ej. Mus., et auct. alior. 

 Procas pyrrhodactylus var., Marsh., Steph. 



H. albicans, griseolus et elongatus, Kirb. MSS. 



This insect in general habit and sculpture very much resembles 

 the preceding ; it may however be distinguished by having the 

 rostrum gradually dilated from the middle to the apex. 



Extremely common on docks in marshy situations.
