COLEOPTERA 



cent. The prosternal process projects considerably beyond the front 

 coxae, is of nearly equal width throughout, with carinate margins. 



Length, nearly 2^ lines ; breadth, nearly ij. 



I captured two specimens on the Waitakerei Eange. 



Cyphanus (p- 308). 



1376. C. mandibularis, n.s. Oblong, moderately convex 

 transversely ; somewhat nitid, castaneous-red, tarsi and trophi 

 yellowish, covered with short fulvous hairs. 



Head broad, distended behind the eyes, punctulated ; labrmn 

 excessively reduced, deeply emarginated, without the orthodox 

 membranous space separating it from the forehead ; mandibles 

 robust, tri-dentate inwardly, almost wholly exposed. Prothorax 

 short, with explanated and rounded sides, its angles obtuse ; finely 

 punctulated. Elytra densely and rugosely punctured, much more 

 coarsely than the thorax, the suture and a linear lunate mark near 

 the apex of each blackish. Antenna elongate, basal articulation 

 thick, second short and stout, third scarcely half the length of the 

 fourth, the others about equal. Labial palpi furcate. 



(Belongs to Cyphanus, but the labrum is so short that the 

 mandibles are almost entirely visible from above.) 



Length, 4 lines ; breadth, if. 



My specimen was found at Parua (Whangarei Harbour). 



Veronatus (p. 



J 377- V. antennalis, n.s. Elongate, oblong, transversely con- 

 vex ; dark-red, legs and antennas reddish ; clothed with yellowish 

 hairs. 



Head densely rugosely punctured; behind the eyes straight, 

 produced anteriorly ; labrum prominent, the membranous part 

 separating it from the forehead large ; eyes prominent. Prothorax 

 transverse, finely marginated and obtusely rounded laterally, angles 

 acute ; with an obsolete dorsal impression, densely punctulated, but 

 not so coarsely as the head. Elytra closely and rugosely punctured. 

 Antenna of moderate length, basal joint thick, second short, third 

 hardly longer but more slender than the preceding, fourth elongate, 

 nearly thrice the length of the third. 



An aberrant form; the anterior prolongation of the head, and 

 the large membranous space and labrum, together, have the effect 

 of concealing almost all but the tips of the mandibles in repose. 



The species cannot be satisfactorily referred to Veronatus, or 

 indeed any other genus, but, as the structure of the head in this 

 group undergoes various modifications, I have not thought it advis- 

 able to create a new genus on that account alone. 



Length, 2f lines ; breadth, i J. 



I found one individual only on the Waitakerei Mountains. 



Cyphon (P. 



1378. C. remotus, n.s. Castaneous, thorax reddish, the 

 greater portion of the elytra blackish, legs and antennae testaceous ;
