Enxestus Parkii. 



E. rufo-castanea, nitidissima, glaberrima ; antennis pedibusque paulo 



pallidioribus. 

 Long. corp. lin. l-\\. 



E. oblong-elliptic, bright reddish chestnut, highly polished, 

 totally free from pubescence, and appearing, except under a high 

 magnifying power, almost impunctate ; but when viewed be- 

 neath a powerful lens, the entire surface will be seen to be beset 

 with small but remote punctures. Prothorax with the hinder 

 margin slightly sinuated. Limbs a little paler than the rest of 

 the surface, being reddish testaceous. 



The discovery of this insect, which so curiously recalls at first 

 sight the common Olibrus liquidus, is due to the indefatigable 

 researches of Mr. M. Park, to whom I have great pleasure in 

 dedicating the species. Three specimens of it, one of which he 

 has presented to the British Museum (the second being in his 

 own possession, and the third having been destroyed for dissec- 

 tion), were captured by him in an ant's nest, in Dr. Lister's 

 garden, at Funchal. 



Fam. Tenebrionidae. 



Genus Adelina, Chevr. (ined.). 



Corpus oblongum vel lineare, valde depressum : prothorace trans- 

 verso- subquadrato ; prosterno postice inter pedes anticos lobato : 

 metasterno postice bifido ; alls amplissimis, lsete nebulosis : abdo- 

 mine e segmentis 5 composite Antennce longiusculse (capite pro- 

 thoraceque conjunctim paulo longiores), ante oculos sub margine clypei 

 insertse, apicem versus moniliformes sed vix incrassatse ; art. l mo re- 

 liquis haud robustiore, 2 do brevi, 3 tio longiusculo, ultimo subgloboso. 

 Labrum transversum, autice rotundatum pilosum. Mandibulce va- 

 lidse cornese triangulares, in medio profunde fisso-sinuatse, una mem- 

 brana aucta necnon ad apicem bifida. Maxillce bilobse, lobis pubes- 

 centibus ; interno parvo angusto brevi, ad apicem ipsum acutissime 

 uncinato. Palpi clavati; maxillares art. l m0 parvo, 2 do 3 tio que ma- 

 joribus crassioribus, ultimo magno erasso securiformi ; labiates art. 

 I mo curva to, 2 do huic paulo breviore sed latiore, subpoculiformi extus 

 leviter producto, ultimo multo longiore crassiore, subfusiformi ad 

 apicem oblique truncato. Mentum transverso-quadratum, basi leviter 

 angustatum, apice integrum submembranaceum et ibidem in medio 

 (ut mihi videtur) lobo elongatissimo subcorneo (ad apicem acuto), 

 inter palpos et forsan ligulee connato, auctum. Ligula membranacea, 

 antice dilatata rotundata ciliata. Pedes graciles, longiusculi : tibiis 

 subtilissime pubescentibus, per marginem exteriorem obscurissime 

 subcrenulatis, ad apicem internum breviter calcaratis : t arsis hetero- 

 meris; posterioribus (sed preesertim posticis) art. l m0 longiusculo.
