No species of Scymnus has been described from Sumatra 

 or Java. Compared with Europsean Scymni they are more 

 hemispherical and more convex. This species is very like 

 Sc. capitatiis Fabr. In the two specimens which I take to 

 be the males the red margin of the thorax is of even 

 width, and the apex of the elytra is much more broadly 

 red than in Sc. capita tus , the latter occupying about a 

 quarter of the elytra. Two other specimens appear to be 

 the females: they have the anterior margin narrowly and 

 not definitely , and the anterior angles of the thorax very 

 indefinitely yellowish. Punctuation obsolete.

Oratus , convexus , fere hemisphce7'icus , nii/er, pxd>e brevi cine- 

 rea vestitus, capite, prothoracis limbo et angulo antieo
