254 Mr. T. V. Wollastou on Additions to Madeiran Coleoptera. 



Aglenus brunneus, Gyll. 



A. fusiformi-cylindricus, rufo-castaneus, nitidus, glaber ; capite pro- 



thoraceque distincte, elytris leviter et minus crebre punctatis. 

 Long. corp. lin. |-^. 



Habitat in locis inferioribus Maderse, a Dom. E. Leacock prope 

 urbem Fuuchalensem repertus. 



Hypophloeus? brunneus, Gyll., Ins. Suec. iii. 711 (1813). 

 Cerylon obsoletum, Steph., 111., Brit. Ent. iii. 98(1830). 

 Anommatus obsoletum, Shuck., Brit. Col. Del. 27, pi. 33. f. 2 (1840). 

 Aglenus brunneus, Ericlis., Nat. der Ins. Deiitschl. iii. 285 (1848). 



A. fusiform-cylindric, being a little constricted at the junction 

 of the prothorax and elytra, reddish-chestnut, bright, and gla- 

 brous. Head and prothorax closely and distinctly punctured, 

 the punctures having a tendency to become confluent. Elytra 

 much emarginated at their base, causing the shoulders to appear 

 advanced; less deeply, and not quite so closely, punctured as 

 the head and prothorax, — the punctures with scarcely any 

 tendency to be disposed in rows. Limbs a shade paler than the 

 rest of the surface. 



The European A. brunneus was first detected in Madeira by 

 Mr. Edmund Leacock (and subsequently by myself in the same 

 locality), beneath some bones and logs of wood in a small out- 

 house, in his garden at the Quinta de Sao Joao, near Funchal ; 

 and it was shortly afterwards ca])tured by Mr. Bewicke amongst 

 vegetable refuse at the Palmeira. 



Genus Prostheca, nov. gen. 



Corpus parvum, angustum, lineare, asperatum : capite porrecto : 

 prothorace longiusculo trapeziformi, ad latera subserrato, antice 

 leviter emarginato : scutello minuto (segre observando) : alis (nisi 

 falloi") obsoletis : ahdomine e segmentis sex (?) composito (apicali 

 minutissimo vix perspicuo). AntenncB prothoracis fere longitudine, 

 rectse, articulis 1™° et 2'^° sat magnis crassiusculis (hoc illo vix 

 rainore), 3''° usque ad noimm multo brevioribus minoribus paulo 

 angustioribus inter se sequalibus, 10'"° et 11'"° capitulum magnum 

 solidum rotundatum valde abruptum biarticulatum efficientibus, inter 

 se arete applicatis (sutura vix observanda). Labrum membranaceum 

 antice vix solidius, quadratum (margine antico integro, angulis 

 vix rotundatis ciliatis). Mandihulce validse cornese triangulares, 

 intus baud dentatae, sed circa medium leviter incisse et membrana 

 parva instructse. Maxillae bilobse : lobo externa breviusculo sub- 

 recto, apice subito truncato et dense barbate ; interna paulo breviore 

 minore, apicem versus dense barbate sed vix uncinate. Palpi 

 maxillares articulis I'"", 2'^°, et 3''° longitudine subsequalibus, 

 1'"° leviter flexuose, 2^*° et 3'''° crassioribus (illo subclavato, hoc sub- 

 globoso), ultimo magno elongate incrassato ovali apice vix acumi- 

 nato; labiates e scapis ligulec connatis surgentes, articulis 1'"° et 2''°
