Coleoptera from Xew Zedhnu/. 24^J 



Group Tenebrionidae. 

 Dkmtrius, gen. nov. 



Budi/ elongate. Palpi sliort, terminal joints securiform. 

 Meutuiii subcjuadrate, rather longer than broad. 'Tibve with 

 small apical spines. Tarsi narrow, simple, finely setose 

 below. Mandibles bifid at apex. Eyes transverse, extending 

 below the surface, not deej)ly emarginate ; the thickened 

 lateral margins of the forehead touch the eyes. Prosternal 

 process of moderate breadth, reaching just beyond the hind 

 margin of the prosternum. Trochanters small but distinct. 

 Antennce thick, inserted in round cavities near the inner and 

 lower margins of the eyes, 11-articulate ; first joint nearly 

 concealed above, third rather longer than broad but not much 

 longer than the fourth ; joints 4 to 8 each a little shorter, 

 but only very slightly thicker than the preceding ; ninth 

 and tenth transverse, only a little broader than the eighth ; 

 eleventh short, oblique at apex. 



From Lorelus it differs by the shape of the eyes, the less 

 broadly securiform terminal joints of the palpi, more slender 

 femora, the more widely separated front and middle coxae, 

 broader epipleurie, and by the simple penultimate joints of 

 the tarsi. 



Demtrius carinufatus, sp. n. 



Elongate, subdepressed, nearly glabrous, having only very 

 minute, hardly noticeable, grey .seta3 ; piceous black, the legs, 

 antenna, and palpi pitchy red. 



Head narrower than the thorax, curvedly narrowed in 

 front of the eyes; the margins of the forehead reddish; it is 

 moderately finely and not closely punctured. Thorax trans- 

 versely quadrate, very slightly rounded and narrowed towards 

 the anterior angles ; behind the middle the sides are almost 

 quite straight, posterior angles rectangular ; lateral margins 

 ■well developed, with distinct channels inside; base and ape.x 

 subtruncate ; its surface moderately, not closely, and some- 

 what irregularly punctured. Scutelluni broad. Elytra 

 broader than the thorax at the base, quite twice its length, 

 their margins more explanate near the shoulders and behind 

 than in the middle ; tiieir surface finely punctate and indis- 

 tinctly rugose ; they have broad shallow stria} ; the interstices 

 are .^lightly and irregularly elevated, the third, fifth, and 

 seventh are more distinctly raised than the others, and become 

 almost carinate behind. Legs nearly bare. Antennce finely 

 pubescent.
