526 COLEOPTERA 



Legs long ; the femora clavate \ tibice compressed, flexuose, termi- 

 nated by rather small spurs ; tarsi four-jointed, spongy below, their 

 basal joint rather small, obconical, second transverse, about twice as 

 broad as the first, third very large, bilobed, fourth elongate, not so long 

 as the other three conjointly, with distinct claws. 



Metasternum moderately elongate, the first and second abdominal 

 segments large, of nearly equal length, third and fourth very short and 

 transversely grooved ; coxcz about equidistant, rather remote. 



In the male the rostrum is rather longer than the prothorax, cylin- 

 drical, slender, arcuated rather slightly, gradually narrowed anteriorly 

 and slightly incrassated at its apex ; on the lower part of the head there 

 is an inter-ocular tooth-like protuberance ; the rostrum is finely bicari- 

 nated below, the lines converge beyond the middle (behind) where they 

 terminate in two very obvious spines or acute protuberances. The 

 antenncB are inserted close to the apex, are quite one line in length, 

 much longer and more robust than in the female, with the funiculus 

 rather shorter than the scape. The prothorax broader than the elytra, 

 longer than broad, oviform, and contracted at the apex. 



This remarkable genus may be placed in proximity to Tychioides in 

 Mr. WoUaston's arrangement ; it is, however, abundantly distinct from 

 any other known form. 



936. O. bellus, n.s. Elongate, sub-depressed, pilose ; body red- 

 dish-testaceous above, legs yellowish, the rostrum and antennse red. 



Female. — Rostrum shining, finely punctate, a little dilated towards 

 the base. Head distinctly punctured, clothed with yellow hairs, the 

 coarse punctation ceasing abruptly behind the eyes, leaving the neck or 

 occiput almost smooth. Prothorax somewhat depressed above, more 

 gradually narrowed anteriorly than behind, roimded laterally, coarsely 

 and rather closely punctured, and clothed with yellow hairs. 



The elytra are elongate, about as wide as the thorax, slightly in- 

 curved near the middle and almost depressed ; they have distinct 

 punctured strise and rugulose interstices, and are rather densely covered 

 with yellowish hairs, which are coarser and shorter than those on the 

 thorax — the coarsest may be termed setse, and are disposed in almost 

 regular lines. 



Under-side shining, pitchy-brown, rather strongly punctured, particu- 

 larly the prosternum, with short pallid hairs proceeding from the punc- 

 tures ; metasternum grooved longitudinally. 



Male. — Rostrum rather coarsely and rugosely sculptured (the coarse 

 punctation, however, terminates suddenly behind the eyes, leaving the 

 broader basal portion or neck almost smooth), indistinctly carinated 

 longitudinally, more or less pilose, red in colour, and not at all dull. 

 Antennce in both sexes pubescent. Prothorax broader than the elytra, 

 longer than broad, and, excluding the anterior contraction, quite ovi- 

 form. 



Length (rost. inch), ^ ; breadth, % 2-2^ lines. 



I found this fine species, three males and two females, in different 

 localities north of Whangarei Harbour,
