The male has the anterior tibia acutely dentate in the middle 
within. Of Rhynch. Vicice 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.

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 PJmjt. 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 places, 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.
