8(j Mr. T. V. Wollaston on the Coleoptera of the Salvages. 



ipsis acutis ; elytris subtilissime alutaceis crenato-striatis, interstitiis 

 distincte punctulatis, testaceis, macidis duabus comniunibus (una sc. 

 minore transversa ad basin sita, et altera maxima dentata postmedia) 

 nigris omatis ; antennis palpisque piceo-ferrugineis ; pedibus testaceis ; 

 palporum labialium articulo ultimo baud securiformi (leviter sub- 

 elavato).

T. head dark-piceous, and rather deeply punctured. Prothorax a shade 

 paler, and more strictly piceous, and with the lateral edges more or less 

 slightly rufescent; a little less deeply punctured than the head, but 

 rather more rugose, especially about the hinder angles ; abruptly trun- 

 cated both before and behind, and much narrowed posteriorly, — the 

 extreme hinder angles, however, being acute and prominent. Elytra 

 subovate, much shortened behind, but nevertheless rather produced in 

 the middle (t. e. at their apical point of junction) ; somewhat acute at 

 their humeral angles, much depressed, and most minutely and delicately 

 alutaceous all over, — causing their surface to be a little less shining 

 than that of the head and prothorax; regularly crenate-striate, and 

 with the interstices rather distinctly punctulated ; testaceous, but orna- 

 mented with two black or dark-piceous patches (common to both 

 elytra) which cover the greater portion of the surface, — the first being 

 comparatively small and transverse, placed at the centre of the extreme 

 base, behind the scutellum, and reaching on each side to about (or a little 

 beyond) the fourth stria, its portion between the third and fourth stria 

 being more or less backwardly produced ; and the second being im- 

 mensely larger, postmedial, sometimes much suffused, and of a zigzag 

 form, being produced both before and behind along the suture, and 

 extending on either side to about the seventh stria. Antenna and 

 palpi piceo-ferruginous ; and with the terminal joint of the labial palpi 

 only very slightly enlarged and subclavate (instead of securiform, as in 

 the ordinary Tan). Legs testaceous. 



The three specimens from which the above description is com- 

 piled have been lately communicated to me by the Barao do Castello 

 de Paiva, to whom I have great pleasure in dedicating the species. 

 From the close resemblance of their elytral patches and colouring to 

 those of the Canarian examples of the T. discouleus, Dej., I had at 

 first supposed them to be the exponents of a merely depauperated 

 and slightly altered form of that insect, from (perhaps) a long isola- 

 tion on the small and remote rocks of the Salvages ; but a more 

 careful inspection has proved that such an opinion (as is too often 

 the case in like instances) is only a superficial one, and that the two 

 species arc not only altogether distinct in their minor features, but 

 even in their structural ones. Indeed, were it not that the speci- 

 mens from the Salvages arc essentially Tari in everything else. I
