 articulations of the club. 



Peltinus Walkeei, sp. n. 



L. c, '75 — '87 mm. Omnino ovalis, validissime convexus, nitidissimus, 

 minutissime et confertim jpunctatus, interstitiis glahris, Tiaud alutaceis, aferri- 

 mus ; pronoto modico, anfice ovaliter rotundato, margine anteriori vix reflexd, 

 pellucidd, minute et confertim punctata, interstitiis glahris nitidissimis, mar- 

 I gine hasali fere recta angulis sat aciitis ; eJytris pvonoto duplo longiorihus^ 

 vix latiorihiis, ad onedia latissimis, minute et sat confertim punctatis, inter- 

 stitiis glahris, nitidissimis, laterihus leviter marginatis, apice ohtuso ; pyqidio 

 minime exserto, nigro ; pedihus hrevibus, piceo-testaceis ; antennis sat longis, 

 rohustis, Icetefiavis. 



Body perfectly oval, exceedingly conxex, very shining, very minutely and rather 

 closely punctured, with the interstices smooth and shining, not alutaceous, deep 

 black. Head very small, piceous ; eyes small ; antennae rather long and robust, 

 bright yellow. Thorax moderate, ovally rounded in front with the margin scarcely 

 reflexed and pellucid, minutely and indistinctly punctured, with the interstices 

 smooth and shining, basal margin nearly straight, with the angles rather acute. 

 Scutellum moderate, triangular. Elytra twice longer, but scarcely broader than the 

 thorax, widest at the middle, minutely and rather closely punctured, with the inter- 

 stices smooth and shining, sides faintly margined, apex very obtuse. Abdomen with 

 the pygidium very slightly exposed, black. Legs rather short, pitchy-testaceous. 

 Under-parts piceous, with the head, prothorax, and edges of the ventral segments 

 paler. 



Differs from P. alutaceus in its rather larger size, oval and not 

 attenuated form, smaller thorax, piceous legs, large bright yellow an- 

 tennae, deep black colour, and sculpture ; from other species it may 

 be known by its much larger size and black colour. 



Habitat : Europe, found in Sardinia, near Cagliari ; J. J. 

 Walker, R.N. 



I have dedicated this species in honour of its captor, who for 

 many years has been so well known as an energetic and most successful 

 Coleopterist. 



As the genus Peltinus appears to be but little known, it may be 

 worth while to add a short diagnosis of the species which have been 

 previously described : — 



P. ALUTACEUS, Beitter. 



L. c, '63 — "75 mm. Sub-hemispheric, very shining, castaneous, distinctly alu- 

 taceous throughout ; thorax ovally rounded in front, legs and antennee bright 

 yellow. 



Found in Dalmatia.
