OF NEW ZEALAND. 865 



joint of tarsi infuscate ; head, beak, and apex of thorax black ; 

 antennae fuscous, club blackish ; sparsely pilose. 



Rostrum not twice the length of thorax, distinctly narrower than 

 the head, arcuated, thickened apically, punctate, the punctures more 

 or less confluent longitudinally. Head oblong, vertex plane, rather 

 coarsely and closely punctated. Prothorax a little broader than 

 long, narrowed and a little constricted anteriorly, not so closely 

 sculptured as the head. Scutellum distinct. Elytra broadest at 

 base, gradually narrowed posteriorly, less convex than thorax^ 

 striate-punctate, the punctures quadrate and somewhat approximated, 

 interstices slightly convex, finely punctured, slightly rugose. The 

 clothing consists of slender hairs nearly of the same colour as the 

 derm, and, consequently, not readily perceptible. Underside reddish- 

 chestnut, punctate, clothed with yellowish hairs. Posterior femora 

 strongly dentiform underneath, tibia arcuated inwardly. 



Length (rost. incl.), if-2 lines ; breadth, --. 



I am indebted to Mr. S. W. Fulton, of Outrarn, for two, and to 

 Mr. T. Chalmer, of Dunedin, for one, examples all mutilated, how- 

 ever. They were taken on Mount Maungatua, Otago. 



1541 . O. picigularis, n.s. Narrow, moderately convex, a little 

 shining, pale reddish-chestnut, beak reddish with pitchy sides, back 

 part of head blackish, tarsi and antennae fulvescent, club infuscate. 



Rostrum as long as thorax, cylindric, scarcely thickened at apex, 

 coarsely punctate. Antenna moderate, basal joint of funiculus stout, 

 club elongate-oblong, as long as the funicle, sub-opaque and pubes- 

 cent. Head rather broad, coarsely punctured. Prothorax as long 

 as broad, constricted in front, sub-conical, sculptured like the head. 

 Scutellum distinct. Elytra not twice the breadth, but three times 

 the length, of the thorax, sub-parallel ; striate-punctate, interstices 

 slightly convex, so punctated as to appear rugose. Body sparingly 

 clothed with slender fulvescent, rather inconspicuous hairs. Legs 

 stout, the middle thighs obviously toothed below, the posterior with 

 a robust, angulated, compressed spiniform process, tibia of the latter 

 considerably arcuated. 



A much narrower form than the typical species, more elongate, 

 the thorax narrower and longer, the head broader, and, consequently, 

 the eyes farther apart. 



Length (rost. incl.), if lines ; breadth, f . 



I picked out one specimen from amongst a general collection of 

 beetles sent by Mr. S. W. Fulton from Mount Maungatua. 



I 54 2 - O. nigrescens, n.s. Blackish, tarsi fuscous, clothed 

 with short, easily seen, cinereous hairs. 



Bostrum nearly as long as thorax, slightly thickened at apex, 

 coarsely punctate. Head broad (as broad as front of thorax), punc- 

 tate. Prothorax rather longer than broad, conical, just perceptibly 

 constricted in front, coarsely punctate. Scutellum distinct. Elytra 

 broader than, and nearly three times the length of, the thorax, sub- 

 parallel ; striate-punctate, interstices nearly plane, finely punctated 

 and rugose. Intermediate femora strongly dentate, but not so much
