and becomes quite distiiict in the middle; the punctuation of the 

 externa! intersticea of the elytra appears a little more distinct.

I ha^e from the same locality the female of I believe a closely 

 allied species in which the thorax is a little metallic, and a second 

 female belonging I believe to yet annother species from Celobes 

 (Pfeiffer!), so that it is clear there is in these Islands a little groiip 

 of species closely allied to 0. ovilis, the chief characteristic of the 

 group being the pecnliar structure of the basal Joint of the antennae. 



Ontliopliagus inibutiis (n. sp.): Cinnamomeus , nüjro-irroratus, 

 pedibus antennisque testaceis , tihiis anterioribus piceis, femoribus inter- 

 mediis swpra medio nigro-plagiatis ; corpore subtus parce breviter pube- 

 scente. — Long, 9 mill. 



Mas: Clypeo medio* prolongato levüerque reflexo, vertue medio cornu 

 laminato, apice acuminato ; prothorace anter ius medio impresso; tibiis 

 anterioribus gracilihis subehngatis. 



Fem. : Clypeo subrotundato , bicarinato ; prothorace anterius sub- 

 binoduloso. 



Clypens almost impunctate in the male, rugose in front in the 

 female, a little prolonged and reflexed in the middle in the male, and 

 with the Vertex produced into an acuminate hörn , somewhat as in 

 0. vacca, in the female short and with two strongly elevated trans- 

 verse carinae. Thorax with tlic front angles very little produced, the 

 basal margin almost absent , it is channelled along the middle , di- 

 stinctly moderately closely punctured , from each puncture rises a 

 Short black hair, the colour is almost cinnamon, but as each punc- 

 ture is placed in a small black spot , this is much obscured. The 

 elytra are distinctly striate, the Interstices distinctly but rather spa- 

 ringly punctured, coloured as the thorax, but the black points fewcr. 

 Pygidium yellowish, moderately punctured, with a rather long pube- 

 scence. Prosternum with the angles not foveolate, metasternum noarly 

 flat, of a yellowish colour , with a metallic tinge and spotted with 

 black. Front tibiae pitchy, with tlieir femora pitchy ir) front, yello- 

 wish behind; four posterior femora yellow, sparingly and coarsely 

 punctured beneath , the middle oues with a large dark mark on the 

 middle of the upper side; tlie knees a little infuscate.
