412 COLEOPTERA. 
Prosternum deeply incurved. Second ventral segment much shorter 
than the basal. The squamae and setae of the underside greyish. 
The description of Sharp’s P. simulatrix (2100) is to some extent 
applicable to this species, which, however, is differentiated by the broad 
shoulders, more slender scape, short basal joints of the funiculus, and less 
sharply defined scrobes. 
Length (rostrum inclusive), 8mm.; breadth, 34 mm. 
Scarcliff, Canterbury. One found amongst dead leaves on the ground 
on the 19th October, 1913, by Mr. T. Hall. 
3881. Protolobus nodosus sp. nov. Protolobus Sharp, Man. N.Z. Coleopt., 
p- 1188. 
Oblong, uneven, opaque ; rufo-piceous, tarsi and antennae fusco-rufous, 
scape darker; covered with depressed greyish-tawny and infuscate scales 
and sappy matter; the setae moderately coarse, wregularly distributed, 
erect on the elytral nodosities, subdepressed on the dorsum, yellowish-grey. 
Rostrum broad, half the length of thorax, not perceptibly carinate. 
Thorax slightly broader than long, widest near the middle, rather more 
narrowed, and depressed, in front than behind, somewhat uneven, with a 
broad more or less interrupted channel along the middle.  Scutellum 
triangular. Elytra oblong, double the length of thorax, quite a third 
broader than it is at the base in the female, rather less in the male, narrowed 
and vertical behind; their true sculpture invisible, appearing substriate ; 
3rd interstices slightly and unevenly elevated, terminating as conspicuous 
horizontal nodosities on the summit of the declivity, those on the 5th 
smaller and placed more in advance. 
Legs stout, bearing infuscate scales and setae, tibiae mucronate, minutely 
denticulate along the inner side, posterior corbels not distinctly cavernous. 
Scape stout, setose, reaching the thoracic apex; 2nd joint of funiculus 
more slender than the basal but almost as long as it is, 3rd slightly longer 
than broad, the others shorter, 7th quite transverse; club triarticulate, 
ovate, not elongate. 
Underside with greyish scales and setae. Prosternum rather short, 
widely emarginate, with contiguous coxae. Metasternum short. Basal 
segment large, subtruncate between the widely distant coxae, twice the 
length of the 2nd, the suture between them straight, the 5th longer than 
the 3rd and 4th united. 
In a specimen denuded with the point of a needle the thorax is seen to 
be finely granulate, and the elytra irregularly striate-punctate. The eyes 
are small and distant from the thoracic apex. 
This well-marked species can be readily identified by its differently 
formed, medially grooved thorax and nodose elytra. 
Male.—34 mm. by 14mm. _ Elytral dise more uneven. 
9. Length (rostrum inclusive), 4mm. ; breadth, 1? mm. 
Mount Algidus, Canterbury ; 3rd December, 1913. Mr. T. Hall secured 
seven examples from leaf-mould.

Coleopt., p. 428 (Jrenimus Pascoe, p. 443). 
Elongate, opaque, piceous, antennae and tarsi fusco-rufous; densely 
covered with depressed, circular, nigrescent or dark-grey squamae and
