TENEBRIONIDAE. 395 



■3854. Cerodolus tuberculatus sp. nov. Cerodolus Sharp, Man. X.Z. 

 Coleopt., p. 1161. 



Convex, oblong, suboval, shining ; head and thorax aeneo-niger, hind- 

 body viridescent, legs rufo-piceous, tarsi and antennae rather paler ; some 

 very minute setae are discernible, and in certain aspects parts of the 

 surface appear faintly iridescent. 



Head evidently narrower than thorax, finely and moderately closely 

 punctured. Thorax only a fifth broader than long, base and apex trun- 

 cate ; its sides with slender margins, only slightly rounded and widest near 

 the middle, gently narrowed but not sinuate behind, with obtusely rect- 

 angular posterior angles ; it is moderately closely and finely punctate. 

 Scutellum usually small and triangular. Elytra of the same width as 

 thorax at the base, not thrice its length ; each with a scutellar and 8 

 other series of punctures, those near the suture more numerous and finer 

 than the ones compo.sing the 4th or 5th series, the interstices finely and 

 irregiilarly punctate ; the top of the posterior declivity near the sides is 

 trituberculate, and there is another, sometimes smaller, tubercle near each 

 of the apices. 



Underside glossy black, sparingly and finely pubescent ; abdomen punc- 

 tate and longitudinally rugose ; prosternal process bisulcate. 



The thorax differs in form from that of 2058, the type of the genus, 

 and is wdthout definite basal sinuo.sities, the scutellum is not transverse, the 

 prosternal process is bisulcate, whilst the tuberculation of the elytra of 

 itself is distinctive. 



Length, 7 mm. ; breadth, 3J mm. 



Moa Basin, Canterbury. Three taken off moss-covered trees on the 

 night of the 3rd December, 1913, at an altitude of 3,500 ft., by Mr. T. Hall. 



3855. Cerodolus capitalis sp. nov. 



Oblong-oval, only modei-ately convex, glabrous ; head and thorax 

 nigrescent and subopaque ; elytra somewhat viridescent ; legs, antennae, 

 and scutellum piceo-rufous. 



Head almost as wide as front of thorax, finely and moderately closely 

 punctured, the forehead more minutely ; the fine yet distinct suture is 

 subtruncate in the middle but extends obliquely forwards to the front of 

 the antennal orbits, there is a transverse median fovea behind. Thorax 

 subquadrate, a fifth broader than long ; its sides finely marginate, almost 

 quite straight from the obtusely rectangular basal angles to beyond the 

 middle and from thence very slightly curvedly narrowed anteriorly ; apex 

 subtruncate, the base bisinuate ; its whole surface very finely, evenly, and 

 moderately closely punctate, with a shallow punctiform fovea near each 

 side, at the middle. Scutellum quite transverse, smooth. Elytra very 

 little wider than thorax at the base, twice its length, very slightly broader 

 before the middle than elsewhere, gradually attenuate posteriorly ; on each 

 there are 6 dorsal series of unequal punctures, those near the suture are 

 moderately fine, the 4th series is larger but not coarse, all become in'egular 

 and indistinct near the base, but striate behind ; interstices finely and 

 irregularly punctate, the 3rd is distinctly elevated along the declivity nearly 

 to the extremity, and the side, on top of the declivity, is trinodose. 



Antennae with the uncovered portion of the basal joint scarcely longer 

 than the next, 3rd distinctly longer than 4th, joints 8-11 evidently broader 

 and more pubescent than the others.
