 *S'. poJitum is much larger, proportionately longer, and uiiJ- 

 rower, with red thorax ; its pale marks are much shorter in 

 an autoro-posterior direction — i. e., they form a narrow trans- 

 verse fascia on the elytra. 



Loc. Seychelles : Silhouette and Mali^, 1908-9. 



Five specimens, from the high forests. In Silhouette two 

 were found, near Mont Pot-k-eau (ca. 1500 feet), and at 

 Mare anx Coclions ; in Mah^ three, from Cascade Estite at 

 about 1000 feet, and from the Mare aux Cochons district 

 at about 1500 feet. 



Named after Monsieur du Roslan, under whom an early 

 expedition visited the Seychelles in 1769.

Long. Corp. U'9-l"0 mm. 



Minute, oval, the front margin of the thorax forming an 

 elliptical curve riarrowing slightly in front, sides of the elytra 

 gradually curved, reaching their widest point a little before 

 tlie middle ; very shining, absolutely impunctate, and 

 glabrous above. Colour-, thorax unicolorous reddish yellow, 

 rather paler at the front margin ; scutellum in most examples 

 reddish yellow, in some darker; elytra pitchy black, diluter 

 at the apices ; in some specimens practically unicolorous, but 

 in most there is near the suture just behind the middle a 

 paler area, which, though very indistinct in some, in other 

 cases forms a suffused transverse pale fascia; metasternum 

 pitchy black, underside of thorax yellowish testaceous, of 

 abdomen reddish ; head, antennas, and legs yellow, clubs 

 of the antennae not darkened. Elytra with lateral margins 

 narrowly reflexed throughout most of their length from the 

 shoulder, these margins visible from above immediately 

 behind the shoulder and again in the posterior half, but 

 scarcely visible (or invisible) for a short space just before 

 the middle; sutural stria |)resent, extending forwards a little 

 beyond the middle. Wings apparently anijjle, but not 

 dissected out. Metasternum quite .smooth, glabrous, and 

 impunctate in the middle, with scanty very short pubescence 

 at the sides J abdomen with longer yellowish pubescence.
