202 RHYNCnopnoRA. \Polyd?usus. 



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 ; 

 antennae slender, the joints rufous or testaceous, with their apices pitchy 

 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 striae, interstices broad and flat ; legs rather stout, femora and 

 tibiae 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. 

 Tower'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, antennae long and slender, red, fuscoxis 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 striae ; 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. 4|-6| mm. 



On young trees, in woods, hedges, &c. (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, 01. (gericeus, 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 ; antennae and legs reddish testaceous, club of former 

 often dusky, femora sometimes pitchy in old abraded specimens, 

 anterior pair evidently dentate. L. 5-5f mm. 



On Artemisia maritima; according to Bedel on maritime Chenopodiacece ; 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, 

 :md at Burnham, on the coast of the Bristol Channel at the beginuing of June" ;
