TENEBRIONIDAE. 395 
3854. Cerodolus tuberculatus sp. nov. Cerodolus Sharp, Man. N.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 composing the 4th or 5th series, the interstices finely and 
irregularly 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 without definite basal sinuosities, the scutellum is not transverse, the 
prosternal process is bisuleate, whilst the tuberculation of the elytra of 
itself is distinctive. 
Length, 7mm. ; breadth, 34 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 moderately 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 irregular 
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.
