90 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Coleoptera. 



An easily recognised species, owing to its proportionally narrow outline, well- 

 impressed elytral grooves, and the relatively small eyes scarcely protruding beyond 

 their dilated and posteriorly prolonged orbits. 

 2 . Length, 3^ lines ; breadth, Ij line. 



Campbell Island ; one female only. 



The third species brought to light by Mr. Marriner. 



Kenodactylus, gen. nov. 



Body depressed, head very large, elytra oviform, apices subtruncate. Mandibles 

 curvate, ridged above, elongate, broad and explanate near the base, curved and 

 acute at apex ; the right inwardly angularly dilated between the base and the middle, 

 with a median tooth ; the left abruptly angulate near the base. Labrum transverse, 

 with a deep median semicircular excision, its angles rounded, each with a conspicuous 

 setigerous puncture, the emargination with 4 smaller ones. Forehead truncate in 

 front, with 2 setigerous punctures near each side, the interantennal suture curvate. 

 Eyes distinctly faceted ; rather small, only moderately prominent, lateral, distant 

 from thorax. Antennae inserted at the sides before the eyes, reaching backwards 

 beyond the base of thorax, filiform, joints 3-11 pubescent, each with a short basal 

 stalk, the basal 2 and base of 3rd with setae only, the 1st much stouter and a third 

 longer than 2nd, 3rd rather longer than 4th. Mentum large, deeply emarginate, 

 bisetose, with a short triangular central tooth. Ligvla not free, nearly invisible, 

 with outstanding frontal setae. Maxillary falfi elongate and stout, 2nd joint arched 

 externally and subclavate, the penultimate gradually dilated ; terminal almost as 

 long as 3rd, tapering towards but not acute at the extremity ; labial with similar 

 terminal articulations, the 2nd bisetose. Anterior coxae prominent, placed close 

 to the hind margin of the prosternum, the intervening process of moderate width ; 

 intermediate similarly separated ; posterior trochanters subcylindrical but stout. 

 Abdomen with 5 nearly equal segments, the last with 2 setigerous punctures at the 

 apex, near each side and distant from the middle. Legs rather slender ; anterior 

 tibiae very deeply emarginated inwardly below the middle. 



Male. — Anterior tarsi with the basal 2 joints widely dilated inwardly, with slightly 

 prominent angles, the 2nd strongly transverse and nearly as long as the exposed 

 upper portion of the 1st, these two with some grey squamae on the expanded parts 

 underneath ; 3rd joint rather small and unsymmetrical, being a little prominent 

 at the inner angle : 4th joint also small, not truly bilobed, having only a short frontal 

 excavation, at the external angle an attached horny lobe proceeds half-way alongside 

 and underneath the 5th joint, whilst featherlike grey setae extend to the extremity 

 of the terminal one. Intermediate tarsi slightly dilated, 1st joint oblong but not 

 the length of the following 2 combined, 5th elongate. Posterior pair longest, their 

 basal articulation as elongate as the terminal one. The 4th joint of both the middle 

 and hind pairs, at the inner angle, have the same corneous protuberance and feathery 

 setae as the corresponding joint of the front pair. All the tarsi bear a few coarse 

 setae above and at the sides, but there is no brushlike vestiture underneath. Claws 

 simple. Terminal segment of abdomen uncovered. 



The presence of squamae on the expanded parts of the basal joints of the tarsi 

 prevents the location of this genus in the Anisodactylidae. The thorax and elytra
