9. Praecipue differt copite breviore, suhquadrato^ metarostro 

 breinssimo, prorostro longiore, fUforrM^ antennarum articulis 

 apicalibus brevioribus , elytrorum declivitate apicali margine 

 minus elevato et incrassato instructa. — Long. 10 '/g — 18 mm. 



Hab. North Borneo, Labuan Isl. 



Two specimens in my private collection. 



Like the preceding species this new one belongs to the 

 2nd group and may be placed near Sch. unicolor (Montr.) 

 and Sch. timoriensis Senna by the elytra being unisulcate 

 along the sutural interstice. Nevertheless, by the head 

 which is strongly notched at the base in the middle and 

 at the sides, this species recalls some other forms of the 

 same group but having the elytra bisulcate along the sutural 

 interstice.
