Polydrusus. | RHYNCHOPHORA. 203 
respect to its capture near Portsmouth, Mr. Moncreaff writes, ‘‘abundant on 
wormwood at the north-western side of our island in May.” 
P. confluens, Steph. Black, more or less sparingly clothed with ashy- 
silvery scales which are arranged in denser lines op centre and sides of 
thorax, and on sides and at each side of suture of elytra, and are often 
more or less abraded; rostrum short; antenne slender, red, fuscous 
towards apex ; thorax with the sides rounded and somewhat dilated, 
contracted in front, closely sculptured; elytra oval, widened behind, 
scarcely narrower at base than elytra, with the humeral prominences not 
strongly marked, and with moderate punctured strie ; femora dark, 
tibie red or reddish, anterior femora plainly dentate. L. 5-53} mm. 
On the broom (Sarothamnus scoparius) and the furze (Ulex Europeus) ; very 
local, but not uncommon where it occurs; Plumstead, Charlton, Gravesend, Wey- 
bridge, Bearsted, Coombe Wood; Brandon, Suffolk ; Hastings; Brighton; Shirley 
Warren, Southampton; New Forest, Lyndhurst, &c.; Bournemouth; Glanvilles 
Wootton ; South Wales ; Scarborough ; Liverpool district. The species has very much 
the general appearance of Sifones regensteinensis. 
PHYLLOBIUWS, Schonherr, 
This genus contains more than a hundred species, of which more than 
half occur in Europe, and the remainder are chiefly found in Northern 
Asia; a few also have been deseribed from India, Ceylon, Abyssinia, 
Chili, &c., but they form an exceedingly small proportion ; P. calcaratus 
has occurred in Canada; they are very closely allied to Polydrusus in 
general appearance and habits, but may be distinguished by not having 
the serobes curved and deflexed, very short and nariform; the an- 
tenne are long or rather long, with the last joints of the funiculus 
usually round ; the thorax is transverse, or about as long as broad; the 
femora are usually, but not always, strongly toothed, and the tarsi have 
the first joint for the most part elongate ; in the males of many species, 
according to M. Bedel, the second ventral segment of the abdomen is 
raised in a transverse fold, which is contiguous to the posterior margin, 
and the female has sometimes a fovea on the last segment. 
The British species may be distinguished as follows :— 
I. Femora strongly toothed. 
i, Elytra without scales, but with distinct long pu- 
bescence ; colour of body black with brown elytra 
A ANEOIE By SOG) 5 6 ae cee emerald : 
ii. Elytra with scales. 
1. Elytra with narrow scales and no apparent 
additional raised pubescence. 
A. Posterior tibia not compressed and carinate 
on their external border; eyes moderately 
prominent, 
a. Legs reddish or reddish-testaceous; scales 
of elytra yellowish green, longer and 
thinner; last joints of funiculus of an- 
tenne considerably longer than broad . . P. CaLcaratus, F, 
b. Legs dark, more or less clothed with 
greenish scales ; scales of elytra bright green
