Phyllobius, Polydrosus and Metallites. 1 7 



2. Polydrosus micans, Y&h., Herbst, GylL, Germ., Steph., Schonb. 



— Pt/ri, 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 in 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 in being clothed with fuscous 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.pterygomalisj 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 Schonherr 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. S. Stevens, by brushing amongst grass 

 the beginning of June : rather local and not frequently met with. 



4. P. pterygomalisy 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, 

 scarcely half the length of the head and nearly as broad, the 

 apex testaceous and emarginated. Antennse 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.
