Coleoptera from New Zealand. 243 



Group Tenebrionidae. 

 Demteius, gen. nov. 



Body elongate. Palpi short, terminal joints securiform. 

 Mentuin subquadrate, rather longer than broad. Tibitje with 

 small apical spines. Tarsi narrow, simple, finely setose 

 below. Mandibles bifid at apex. Eyes transverse, extending 

 below the surface, not deeply emarginate ; the thickened 

 lateral margins of the forehead touch the eyes. Prosternal 

 'process of nioderate breadth, reaching just beyond the hind 

 margin of the prosternum. Trochanters small but distinct. 

 Antennce thick, inserted in round cavities near the iiuier 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 clifFers 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 coxse, 

 broader epipleurce, and by the simple penultimate joints of 

 the tarsi. 



Demtrius carinulatus, sp. n. 



Elongate^ subdepressed, nearly glabrous, having only very 

 minute, hardly noticeable, grey setaj ; piceous black, the legs, 

 antennge, 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 apex 

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

 what irregularly punctured. Scutellum 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 : their surface finely punctate and indis- 

 tinctly rugose ; they have broad shallow striaj ,' the interstices
