('oleoptera.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 105 



Lahriun rather jjroniinent, almost horizontal, semicircularly hollowed in front. Head 

 broad, the clypeus separated from the forehead by a Hexuous furrow ; widely 

 rounded and marginated in front. Antennae 8-jointed ; the basal joint stout, 

 obconical ; 2nd pyriform ; 3rd elongate, obconical ; 4th and 5th of variable form ; 

 joints 6 to 8 forming an oval club. Prothorax transversal, widely and strongly 

 emarginated in front, with a membranous border, rounded and somewhat angulated 

 laterally, and rather strongly lobate medially at its base. Ehjtra (jval, moderately 

 convex. Anterior tibiae tridentate, the others carinated externally. Tarsi rather 

 long, their joints thickened apically. Claws long, simple, moderately arcuate. Pl/gi- 

 dium transversal. 



There are about twenty members of this New Zealand genus. Among these 

 there is much diversity in the structure of the antennae, there being 5 very elongate 

 leaflets in the club of some species. The sternum is usually thickly covered with 

 long hairs. 



Odontria longitarsis, sp. nov. (Plate III. tig. 14.) 



Subopaque, broadly oviform, moderately convex, sparingly clothed witli Hne 

 short testaceous setae ; the surface more or less variegated with dull fuscous and 

 rufo-castaneous ; palpi, antennae, and tarsi red, legs infuscate testaceous ; ventral 

 segments variegate, fuscous and fusco-testaceous, with somewhat elongated punc- 

 tures and very scanty pubescence ; the metasternum testaceous. 



Chjpeus distinctly marginated, subtruncate in front, its punctuation rather 

 shallow, moderately coarse, not very close, somewhat rugose ; it is quite glossy, 

 and reddish-brown. Head also shining, darker than the clypeus, with better-defined, 

 larger, and more distinctly separated punctures. Thorax strongly transverse, bi- 

 sinuate at base, widely incurved in front, the anterior angles not projecting beyond 

 the back of the eyes, posterior angles rectangular but obtuse ; its sides gently rounded, 

 very finely margined, and bearing numerous rigid rufescent setae ; disc opaque, 

 fuscous, the sides broadly pale rufo-fuscous ; punctuation distinct, yet rather fine. 

 Elytra of exactly the same width as thorax at the base, widest behind the middle, 

 apices individually broadly rounded ; their striae well marked alongside the suture, 

 less so beyond ; the sculpture of these striae peculiar — not definite punctures, but 

 shallow elongate impressions, each minutely margined ; the interstices closely trans- 

 versely rugose ; the sides bear stiff reddish setae, but there are very few on the disc, 

 those that are visible usually arise from the few scattered pale spots. Pygidium 

 very closely and minutely sculptured. Legs shining, elongate. Anterior tibiae tri- 

 dentate externally. All the tarsi very long and slender, quite a third longer than 

 the tibiae. Antennae short, the exposed part of the basal joint not much longer 

 than the 2nd; 3rd more slender, just longer than broad ; 4th short and transverse, 

 slightly produced inwardly. Club short, quadriarticulate. its 1st joint quite one- 

 third shorter than the others. 



A large species, without the common sternal villosity, and with dift'ereut clothing 

 above. The peculiar sculpture of the elytral striae is without precedent.
