INSECTA MADERENSIA. 301 



227. PMoeophtliorus perfoliatus, W'^oll. (Tab. VI. fig. l.) 



P. brevi-subcylindricus niger rugulosus et pilis rigidis vestitus, prothorace parce subpunctato, elytris 

 obscure striato-puuctatis, antennis pedibusque piceis, tarsis pallidioribuSj articulo ultimo testaceo. 

 Long. Corp. lin. |. 



Habitat in sylvaticis locorum editiorura Maderae, rarissimus : ad Lombo das Vacas solstitio sestivo 

 A.D. 1850 duo specimina inveni. 



P. short and subcylindrical, almost opake, black, and clothed with a short, thick, rigid, cinereous and 

 somewhat scaly pubescence. Prothorax convex and rounded, rugulose, beset with rather large 

 but somewhat obscure and irregular punctures ; very slightly produced in front, where there are 

 no indications of any additional asperity. Elytra likewise rugulose, and with both the punctures 

 and setse arranged in rows ; rounded and entire at their e.xtremity. Antenna and kffs slightly 

 piceous; the latter with their tarsi paler, — especially the apical joint, which is testaceous. 



Apparently exceedingly rare, and confined to remote sylvan spots more or less 

 difficult of access. The only two specimens which have come beneath my observa- 

 tion were captured by myself, June the 21st, 1850, on the extreme summit of the 

 lofty mountain-preciiiice which forms the eastern barrier of the Ribeira de Sao 

 Vincente, — immediately before entering the almost inaccessible district of the 

 Lombo das Vacas. 



Genus 105. HYLURGUS. 



Latreille, Gen. Oriist. et Lis. ii. 274 (1807). 



Corpus sat parvum, subovato-cylindricum : capita leviter producto : prothorace antice subacuminato, 

 vix producto et baud scabroso : elytris apice rotundatis, fere integris : alis amplis. Antenna 

 breves capitatse; scapo elongato subclavato, basi fle.xuoso ; funiculo 6-articulato, articulo prnuo 

 robusto apice truncato ad basin constricto sinuato, reliquis longitudine decrescentibus, a basi 

 angusta latitudine paulatim crescentibus ; capitulo solido ovato quadri-annulato. Labrum 

 obsoletum. Mandibula cornese validse triangulares subacutse, infra apicem dente robusto obtuso 

 instructfe, ad basin integrse. Maxilla lobo singulo lato brevi setoso instructee (interno obsoleto). 

 Palpi subsetoso-conici ; maxillares minuti, articulis prime, secundo et tertio brevibus trans- 

 versis, ultimo graciliore subconico ; labiates longiores, articulo primo crasso, secundo paulo bre- 

 viore crassiusciUo, ultimo graciliore subconico. Ligula membranacea elongata, basi angustata, 

 apice truucata. Pedes parum breves, validi : tibiis compressis, apicem versus extus denticulati.s 

 et dilatatis, ad apicem internum spina (in anterioribus subcurvata robust^ sed in posticis subreeta 

 acutiuscula) armatis : tarsis pseudotetrameris, articulo primo longiusculo, quinto elongato vix 

 subclavato unguiculis simplicibus munito. 



With the exception of Scolytus (which however has its tibiae not only entire, 

 but likewise produced into a curved claw, as in many of the Curcwlioiiiclce, at 

 their outer apical angle), Hylurgas is the only Em-opean genus, in either the 

 present family or the previous one, in which the funiciilus is composed of six 

 joints. In the structm-e of their oral organs and feet the members of the Bhyn- 

 cophora are for the most part nearly coincident ; and hence, in that section, we
