202 RHYNCHOPHORA. [Polydrusus. 
scales, the upper surface without hairs ; head rather large, subquadrate, 
closely punctured, forehead with a fovea in middle; rostrum a little 
shorter and narrower than the head, the apex triangularly emarginate ; 
antenne slender, the joints rufous or testaceous, with their apices pitehy 
and the club fuscous; thorax short, transverse, a little narrowed and 
slightly constricted anteriorly, with the sides moderately rounded and 
dilated ; elytra subconvex, with the shoulders marked, and with punc- 
tured strie, interstices broad and flat ; legs rather stout, femora and 
tibiee black, the former toothed, tarsi rufous. L. 5-6 mm. 
On young oaks; very rare ; Llandudno, May, 1865 (Sidebotham) ; Silverdale, May, 
1866 (Power); Lydiate, near Liverpool, August, 1887 (Ellis); a specimen in Dr. 
Power’s collection standing under this name proved to be Phyllobius maculicornis : 
Walton records one specimen as in the British Museum, but without locality. 
P.cervinus, L. Black, clothed throughout with golden or silvery 
green, sometimes ashy scales, the colour being very variable; elytra 
nearly unicolorous or with more or less distinct denuded spots; head 
with a small fovea, antenne long and slender, red, fuscous towards 
apex ; thorax nearly as long as broad, with the sides very slightly 
rounded ; elytra with the shoulders prominent and square, with com- 
paratively deep punctured striz ; legs black, with ashy pubescence, tarsi 
fuscous, all the femora with a small acute tooth; the species is often 
very much abraded ; the specimens with green scales are sometimes con- 
fused with allied insects; the shape of the scrobes will separate it from 
any of the Phyllobii, and the toothed femora and dark legs from P, ptery- 
gomalis and P. flavipes ; size very variable. L. 45-63 mm. 
On young trees, in woods, hedges, &e. (especially on oak, birch and fir) ; generally 
distributed and more or less common throughout England and Scotland, and 
probably Ireland. Dr. Sharp records it as common in Scotland on Scotch fir. 
P. chrysomela, Ol. (sericeus, Steph. nee Schall.; pulchellus, Steph.). 
A beautiful and conspicuous species, which is, however, very often 
more or less abraded, black, with shining green, golden-yellow, coppery 
red or silvery grey scales, which are scanty on the head and thorax, and 
on the elytra are arranged very thickly at the sides and on two lines 
on the elytra, which in consequence present a longitudinally banded 
appearance ; rostrum short, head broad ; thorax with the sides strongly 
rounded and dilated, with short hairs mixed with the scales ; elytra oval 
with the humeral prominences slightly marked, only a little broader at 
base than thorax ; antenne and legs reddish testaceous, club of former 
often dusky, femora sometimes pitchy in ‘old abraded specimens, 
anterior pair evidently dentate. L. 5-53 mm. 
On Artemisia maritima; according to Bedel on maritime Chenopodiacee ; appa- 
rently a littoral or submaritime insect ; Walton records having 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 Bristul Channel at the beginning of June”? ;
