fere impundato ; elytris evidenter suhtüiter striatis , interstitiis crehre 

 obsoletius pundatis. — Long". 12-13 mill. 



Mas: Clypeo ehngato, apice reßexo, Imnina verticali redmata. hrcvi, 

 apicem vcrstis attenuata; tibüs anteriorihus gracilibus, elongatis. 



Fem. : Clypeo bicarinato, carina verticali meäio indidinde elevata. 



About the size of 0. austriacus; clypeus with the surfaco entirely 

 piinctured in tlie female, in the male with the lamina smooth. An- 

 tennae obscnre reddish with tlie club in pavt darkcr, the basal Joint 

 with the front margin produced so as to form an edge , which is 

 marked with deep lines so as to give it a crenulatc appearance. 

 Thorax with a dense fine punctuation in front which becomes obsolete 

 at the base in the middlo, the bind angles are indistinct, the basal 

 margin is conccaled ; in . the female it is quite simple, in the male 

 just behind the front margin, it is perpendicular, and very slightly 

 iraprcssed in the middle for tho vertical lamina. Tlie elytra are finoly 

 striated, the Striae being simple , the puiictuatiün of the interstices 

 very obsolete. The pygidium coarsely but not deeply sculptured. 

 The front angles of tho prosternum are punctured and not imprcssed; 

 the metastornum a little cariiiate in the middle towards the front*). 



Celebes (Wallace !). 



I have also a variety with the thorax rather more distinctly 

 punctured from Menado , and a closely allied but probably distinct 

 species from Sula Island, 



Ontliopliagus siimdans (n. sp.): Niger, vix mtidtis, antennis rufis : 

 prothorace dense , hasi medio obsoletius pimdato , margine basali medio 

 bene discreto; interstitiis internis opacis, externis crebre subtiliter punc- 

 tatis. — Long. 11 mill. 



Mas : Clypeo leviter producta , medio suhreflexo , lamina verticali 

 brevi medio cornu brcvi aciiminato, tibiis anteriorihus gracilibus elongatis. 



This species is very closely allied to 0. ovilis but diflFers in the 

 form of the vertical lamina, as well as by the more distinct punctua- 

 tion of the thorax, and by its basal margin, which is less obsolete 



*) This species inay possibly be my 0. Wallacei (Col. Heft. VIII. p. 114), 

 but as tliere scems to be in these Islands a whole group of closely allied 

 species, it would be premature at present to declare it as such.
