Seychelles and Rangoon. 19 



tlie antennae to di.stingulsli ti^number of forms superficially 

 much alike. 



Among species vvhicli I have not seen, 8. eichelbauml, 

 Reitter (1908, p. 62, E. Africa), seems to resemble S. {A.} 

 seycliellensis in some respects, but to differ (as, according to 

 Reitter, I. c, does also the Australian S. pallidulus, Reitter) 

 in iiaving the punctuation of the elytra obsolete towards the 

 base; also eiclnlhaami and pallididas presumably belong to 

 the subgenus Sericoderusj s. str., though this is not actually 

 state 1. Certain forms have been described from Austrab'a 

 by Lea * and from New Zealand by Broun f, but it is 

 impos-sible to say exactly how they are related to S. (A.) 

 S'l/cfiellensis. S. (A.) pecirkanus^ Reitter (1908), fro^n 

 Egypt, is, according to the description, different in sha[)e, 

 cohjui-, and nature of the pubescence. 



Log. Seychelles : Silhouette and Mahe, 1903-9. 



Over fifty specimens, varying considerably in size. . In 

 Silhouette several were swept from a grassy clearing at over 

 1000 feet, 30. vii. 1908, and a large number were beaten 

 all together from one place on the edge of the forest at Mare 

 aux Cochons, over 1000 feet, in the late aftertioon of 18. ix. 

 1908; others were found in various localities both in the 

 high forests and at lower elevations. In Mahe examples 

 were taken in the high forest of Morne Blanc^ on Casca«le 

 Estate, &c.

Anteuuse (ut in OUgarthro) S-articulatte, sed ab eis OUgarthri in 

 forma articulonim differentes. Caput sub x>ronoto omnino ob- 

 tectuin. Genus in forma mandibulorum, masillarum, labii, 

 Coryloplio affinis, sed ab hoc genere in uiimero articulorum 

 antenuarum differfc. 



Form (fig. 18) oval, narrowed behind, moderately convex, 

 glabrous above. Head entirely concealed beneath pronotum. 

 Antennce (fig. 19) 8-jointed ; joint 1 long, thickened, curved 

 towards base ; 2 pyriform, over twice as long as broad ; 

 3 slender at base, a little longer than broad ; 1 small, a little 

 broader than long; 5 may be reckoned as part of the club, it 

 and 6 are about as long as broad ; 7 is rather broader than 

 long; 8 is longer than broad and tapers to a blunt apex. 

 Labrum (fig. 21) transversely oblong, anterior angles
