and with the frontal transverse ridge ahnost obsolete in the 

 middle, and pointed at each end in the male, while in the female 

 it is of uniform size throughout. Thorax in the male, with a 

 prominent advanced tubercle in front and in the middle, and two 

 small tubercles on each side placed along the line of the retuse 

 anterior front of the thorax, which is perpendicular and consider- 

 ably behind the advanced central tuberosity, which is slightly 

 eraai'ginated by the median line ; in the female, with the advanced 

 central prominence also subemarginate, but very broad, and with 

 only one small tubercle between it and the sides. Elytra with eight 

 fine stri^ on each, and with the interstices broad, flat, and very 

 finely punctate. Body beneath clothed with long fulvous hair.

 Black, nitid. Head very finely and transversely punctate on 

 the forehead, and densely and rugosely on the clypeus, which is 

 broadly rounded and moderately reflexed along the margin. 

 Thorax quite smooth and without any mark excepting the lateral 

 fovea. Elytra punctato-striate, with the interstices almost quite 

 flat and smooth. Tibite piceous. 



This species is not unlike 0. mutictis described by me from 

 Port Denison, in the transactions of the Entomological Society of 

 New South Wales, for the year 1864. It difiers from it in being 

 smaller, more brilliant, smoother on the thorax, and more deeply 

 striated on the elytra. The only difference I can perceive 

 between the sexes, both in this species and in 0. muticus, is in 

 the much more strongly developed teeth on the exterior of the 

 anterior tibi^ in the female.

 Black, subnitid. Head coarsely punctate, rugose, toothed and 

 emarginate in front. Thorax densely punctate, transverse, bi-

 rounded at the base, with a broad depression near each side, and 

 a deep broad transverse depression behind the middle, which
