I20 COLEOPTERA 



223. O. pullllS, n.s. In general outline and colouration, this 

 species closely resembles O- crenuiatiis, but only the three first joints of 

 the antennce are red and longer than broad, whilst the following seven 

 are sub-quadrate and of an obscure fuscous colour. The head is tri- 

 gonal, with large, prominent, distinctly facetted eyes, and distinct, shining, 

 antennal orbits ; its punctation is neither close nor coarse, the space 

 between the antenna? dull and impunctate. The prothorax has incras- 

 sated, entire, side margins, rounded before the middle, narrowed, but not 

 sinuated, posteriorly, with distinct, though not acute, hind angles ; three 

 discoidal furrows extend from base to apex, and it is also broadly im- 

 pressed at each side, where the punctation is closer and coarser than 

 elsewhere. Elytra broader than thorax, closely covered with elongate 

 punctiform impressions so as to appear longitudinally wrinkled. Abdo- 

 men very sparsely pubescent, the segments not fringed behind. Front 

 tibicB spinous externally and somewhat excised near the apex. 



Length, i|-2 lines ; breadth, nearly \. 



My two specimens were detected at Parua. 



224. O. tibiale, u.s. Head and thorax pale castaneous, the 

 latter the lighter in colour ; elytra and hind-body testaceous shaded with 

 brown ; legs pale yellow ; the last six joints of the antennjie dull, blackish, 

 the first testaceous, joints two to four intermediate in colour. 



Head smaller than thorax, and, as far as the margin of the epistome, 

 quadrangular ; a quadrate space in front limited by linear depressions 

 is finely sculptured and less glossy than the other parts of the head, 

 there is an elongate depression on the vertex, and the surface generally 

 is punctate, more coarsely near the eyes. Prothorax a good deal 

 broader than long, as wide as the base of the elytra behind, where it is 

 rounded, it is moderately curved at the sides, and not greatly narrowed 

 posteriorly; the disc is tri-sulcate, the space near the front angles slightly 

 raised, so that there seems to be a broad depression near the middle of 

 each side, its surface is punctured, the linear spaces between the dis- 

 coidal furrows least so. Elytra rather longer than thorax, widest behind, 

 truncate at apex, each elytron with a broad shallow depression pro- 

 ceeding from the shoulder; their whole surface is moderately punctured, 

 and the sides and concave parts darker in colour than the rest. Abdo- 

 men obsoletely punctured, the hind margin of the four basal segments 

 indistinctly ciliated with greyish hairs. The anterior tibia' are gradually 

 expanded and spinous to beyond the middle, and from thence abruptly 

 excised towards the extremity, thus leaving an evident gap at the apex ; 

 the intermediate are finely and regularly fringed with spines along their 

 whole outer edge ; the posterior are simple. The body is nearly nude, 

 and not very glossy. The four basal joints of the antennce are more 

 slender than those which follow ; their orbits are a little elevated and 

 shining.

I found my specimen at Tairua.
