About tlie size of 0. ovatiis, but flattor, narrower and more pa- 

 rallel in form. Clypeus completely roun^ed in front, along the middle 

 with a curved line, and between the eyes witli a sliorter straight line, 

 which in the S is elevated as a narrow lamina, the front part is red- 

 dish brown, the hinder part has a metallic lustre, the punctuation is 

 of the same character as that of 0. ovatus, but rather coarser and 

 closer. The tliorax is quite simple and closely covered with setigerous 

 punctures, there is a Channel in the middle behind, the basal margin 

 is not visible. The elytra are distinctly striated , tlie Striae being 

 deeper than in 0. ovatus, the interstices are rather closely punctured 

 and would be shining but for the punctuation and pubescence. The 

 pygidium is rather coarsely, moderately closely punctured. The angles 

 of the prosternura are not foveolate; the metasternum is rather coar- 

 sely but not closely punctured, it is channelled in the middle behind, 

 and protuberant in front , the middle femora are moderately closely, 

 the bind ones sparingly punctured. The anterior tibiae are short and 

 stout, with their teeth directed outwards, their apex nearly truncate. 



Menado (Wallace!), also a specimen from Celebes, which may bo 

 an individual of a variety of this species. 



Synarmostes puncticoUis (n. sp.) : Nigro-pkeus , hreviter parcim 

 setuhsus, capite thoraceqtie omnino dense , for titer profundequc ocellato- 

 punctatis; elytris crehre seriatim punctatis, punctis apicem versus ocellatis. 

 — Long. 4^/4 mill. 



Head and thorax very densely punctured and not shining, the 

 punctures are coarse and the interstices very narrow, even the punc- 

 tures at the base of the thorax in the middle, are coarse and deep, 

 and the interstices very small; the surface is sprinlded with fine short 

 setae, which are very scanty at the lateral margins. The elytra are 

 rather closely punctured, the punctures being at the extremity coarse 

 and dense, and each puncture there distinctly ocellated ; the punctures 

 become fine towards the base, and consist on the basal portion of 

 alternate series of very fine and of coarser punctures. The antennae 

 legs and under surface are obscure reddish. 



This species is closely allied to S. Gestroi, but is rather broader 

 and may be readily distinguished from it , as well from the other 

 species here described, by the very coarse thoracic punctuation.
