tlie anteniiEe to distinguish u number of forms superficially 

 much alike. 



Among- species wliicli I have not seen, 8. eichelbaumi, 

 Heitter (1908, p. 62, E. AtVica), seems to resemble S. {A.} 

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

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

 in iiaving the punctuation of the elytra obsolete towards the 

 base; also eick'lbaumi and pallidulus presumably belong to 

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

 stated. Certain forms have been described from Australia 

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

 impossible to say exactly how they are related to S. (A.) 

 seychellensis. S. (A.) pecirkanus, Reitter (1908), front 

 Egypt, is, according to the descri|)tion, different in shape, 

 colour, and nature of the pubescence. 



Log. Seychelles : Silhouette and Mah^, 190S-9. 



(Jver 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 (jochons, over 1000 feet, in the late afternoon of 18. ix. 

 1908; others were found in various localities botii in the 

 high forests and at lower elevations. In Mahe examples 

 were taken in the high forest of Morne Blanc_, on Cascade 

 Estate, &c.
