INSECTA MADERENSIA. • 307 



describes eighteen species from Europe, four from Asia, six from Africa, and nine 

 from America. In the Madeira Islands I have liitherto detected but a single 

 species, namely the 



232. Rhyncolus tenax, wbll 



R. subcylindricus rufo-brunneus plus minusve subseneus, rostro in medio carinato, prothorace crebre 

 punctato latiusculo, elytris subcinerco-pubescentibus leviter punctato-striatis, aii.tennis pedibusque 

 ferrugineis. 



Long. Corp. lin. li-2. 



Habitat sub cortice arborum laxo et in ligno putrido Maderse, praesertim per regionem sylvaticam, toto 

 anno vulgaris. 



■'b" 



R. subcyliudrical and rather depressed, reddish-brown with more or less of an seneous tinge, especially 

 on the prothoras. Rostrum rather broad and linear, and keeled down the centre. Prothorax 

 thickly and rather finely punctured, and with very faint indications of a keel down the disk, 

 broadest just behind the middle (where it is almost as wide as the elytra), and a little constricted 

 at the anterior margin. Ehjtra parallel, and somewhat transversely-rugulose, lightly punctate- 

 striated, and more or less clothed with a fine decumbent yellowish pubescence. Anteima and 

 legs ferruginous. 



A most abundant insect throughout the sylvan districts of Madeira, occurring 

 beneath the bark of trees (especially that of the Vinhatico and Til), and in the 

 substance of the rotten wood, in nearly all the dense ravines of intermediate and 

 lofty altitudes. I have taken it at the Curral das Romeiras, near Funchal, during 

 the autumnal and vidnter months ; at Santa Anna, and the Ribeiro Erio in May ; 

 at Sao Vincente and the Lombo das Vacas in June ; and at the Cruziuhas, the 

 Eanal, and the Lombo dos Pecegueiros, in July. 



Genus 108. PHL(EOPHAGUS. 



Schonherr, Gen. et Spec. Cure. iv. 1047 (1838). 



Corpus parvum, subcylindrico-ovatum, plus minusve sculpturatum : rostro elongato teretiusculo sub- 

 arcuato deflexo : prothorace convexo ad latera sub?equaliter rotundato, antice vix coarctato : elytris 

 subovatis basi truncatis, supra (prajsertim posterius) convexis : alis (in specie nostra) obsoletis. 

 Antenna: breviusculae subtenues, in medio rostri insertse; funiculo 7-articulato, articulo prime 

 (tantum, in specie Maderensi) majore, reliquis brevioribus, ultimo clavse baud arete adpresso; 

 capitulo solido subovato, obscurissime annulato. Pedes fere ut in Rhyncolo, sed antici basi 

 plerumque approximate 



The JPhlceoiihagi are a good deal allied to the Rhyncoli, nevertheless they may 

 be known from them by tlieii" more ovate outUne, and by their longer, narrower, 

 and more deflexed rostrum. They are usually also more convex, especially behind, 

 their surface is more deeply sculptured, theu- prothorax is more regularly rounded
