Phyllobius, Polydrosus and Metallites. 19 
7. Polydrosus Chrysomela, Oliv., Schénh. Supp. vi. p. 447, Germ. 
— sericeus, Steph., Curt., non Schaller. 
— pulchellus, Steph. Manual, p. 249. 
In my long series of varieties of this insect I have recent spe- 
cimens clothed with shining green scales, some golden-yellow gr 
coppery-red, and-others of a silvery-gray ; older specimens are 
found with the scales more or less abraded, and the colour of the 
legs obscure testaceous, and sometimes the femora are piceous : 
the form of the elytra varies very remarkably ; some are consi- 
derably narrowed, and the sides nearly straight, whilst others are 
much broader, having the sides regularly dilated and rounded 
from the shoulders to the apices, and very convex above; the 
second and sixth interstices from the suture on each elytron are 
more or less distinctly lineated, in consequence of being more 
densely clothed with paler scales than the others. 
Specimens which I sent to Germar were referred to “ P. 
Chrysomela, Oliv., Schénh.” P. sericeus of Stephens and Curtis 
(according to the insects in their cabinets) is beyond all doubt 
identical with this species, and it is my opinion that P. pulchellus 
of Stephens (represented in his cabinet by one insect) is but a 
narrow variety with “ golden griseous scales.” 
Apparently a littoral or submaritime insect: I have taken it on 
grassy banks, just above high-water mark, on the shores of the 
Thames below Gravesend, and at Burnham, on the coast of the 
_ Bristol Channel, the beginning of June. 
8. P. confluens (Kirb. MSS.), Steph. Illust. (1831). 
— amaurus, Steph. 
— Chrysomela, Schinh. ii. (1834), Steph. Manual (1839). 
— perplexus (Dej. Cat.), Schénh. Supp. vi. (1840). 
Mr. Stephens appears to be the first author who described this 
insect, since which he refers it in his ‘ Manual of British Coleo- 
ptera’ to Chrysomela of Olivier after Schénherr ; subsequently 
Schénherr, in his Supplement, changed the name for perplexus of 
Dejean Catal., and upon the authority of Schuppel, applies Chry- 
somela to the preceding species. 
I possess two foreign imsects from Chevrolat, with the name 
— of Dejean, which are identical with the confluens of 
irby. 
I have taken this insect rather plentifully near Lyndhurst, 
Hants, and also on the south side of Windmill Hill near Graves- 
end, and in other places, always on the furze (Ulex europaeus), in 
July: on broom at Plumstead, Charlton and Weybridge from 
June to September, Mr. S. Stevens.
