Phyllobius, Polydrosus and Metallites. 17 
2. Polydrosus micans, Fab., Herbst, Gyll., Germ., Steph., Schonh. 
~ — Pyri, Linn., Mus. Linn., Kirb. MSS. ? 
The general colour of the scales of this insect are of a coppery 
fiery-red. 
Not frequently met with. I have taken it im Swanscombe 
Wood, near Gravesend, on the oak underwood in June. 
3. P. flavipes, DeGeer, Gyll., Steph., Schonh. 
Major Gyllenhal has described this insect with his accustomed 
accuracy and precision, and Mr. Stephens has given shorter de- 
scriptions in his ‘ Illustrations’ and in his ‘ Manual of British 
Coleoptera’; but from its near affinity to P. pterygomalis, it has 
hitherto been confounded by British entomologists with that spe- 
cies ; it differs principally im being clothed with fuscons hairs, 
the abdomen with scales, and: in being distinctly different in the 
form of the head. I have specimens of P. impressifrons from 
Chevrolat, which is decidedly more closely allied to this species 
than P. pterygomalis, and with much difficulty distinguished from 
P. flavipes ; yet I am satisfied it is sufficiently distinct ; it differs 
chiefly in having the head narrower, the vertex less convex and 
slightly dilated behind the eyes, the frons very deeply impressed, 
_ the eyes less prominent, the rostrum elevated at the sides and 
much depressed above ; the thorax flat above, with a deep oblong 
impression on each side behind the middle, and very sparingly 
clothed with shorter hairs. 
Of P. impressifrons and P. flavovirens of Schoénherr and of 
Stephens’s ‘ Manual,’ I have never seen indigenous specimens. 
In the cabinets of Mr. Waterhouse, Mr. S. Stevens and myself. 
Taken in Windsor and Henhault Forests, and also near Ham- 
mersmith Bridge, by Mr. 8. Stevens, by brushing amongst grass 
the beginning of June: rather local and not frequently met with. 
4. P. pterygomalis, Schonh. Supp. 
— flavipes, Marsh., Kirb. MSS. 
Oblong, black, clothed with brilliant green scales sometimes 
of a shining golden colour, and with erect pallid hairs. Head 
broad, the vertex transversely elevated and very distinctly cari- 
nated on both sides, narrowed at the base and thickly punctu- 
lated ; eyes round and prominent, black; rostrum very short, 
searcely half the length of the head and nearly as broad, the 
apex testaceous and emarginated. Antennz reaching beyond the 
base of the thorax pallid testaceous, pubescent ; clava oblong, 
acuminated. Thorax rather broader than long, narrowed and 
constricted anteriorly, moderately rounded at the sides, trans- 
versely convex in the middle, closely and thickly but not deeply 
punctulated, the punctures confluent. Scutellum triangular.
