menfnm (fig. 2) is narrow, |)ointe(l in tVoiif, ami tlie terminal 

 joints of the Idlial p(tlpi slightly hunger than tlie second. 



Sacinm j)i<^<iultianum approaciies three species which I 

 liave seen — S. bifasdatum^ Matth. (Madagascar), S. quaclri- 

 vi'iculatum, Matth. (Ceylon), and 8. flaviventre, Mattli. 

 (Ceylon), Mon. pp. 53, 54. S. hifasciatum is slightly 

 longer in pro|)ortioii, more tapering behind, much more finely 

 punctured, with the basal thoracic series much less distinct, 

 and the light marks on the elytra less sharply defined and 

 ditferently arranged. S. qnadrhiaculatum and S. flaviventre 

 are h:)th larger and differently shaped in outline, having the 

 elytra less parallel-sided and broadening out ratlier more 

 beliind the shoulders ; both have the disc of the thorax dark 

 red instead of pitchy black and the marks on the elytra much 

 smaller; moreover, the upper surface is entirely glabrous, 

 the punctures being devoid of even such minute hairs as are 

 })resent in S. picauUiinum. The latter is quite distinct froiu 

 anv of the three. 



Loc. Seychelles : Silhouette Island, 1908. 



Fifteen specimens. Nine were beaten irom dead palm- 

 haves on the i\lare aux Cochons plateau, over 1000 feet, 

 25. ix. 1908 ; five others are from the same loealit)^, though 

 how obtained is not recorded ; and one is from the other side 

 of the island, near Ment Pot-a-eau. 



Named after Captain Lazare Pieault, who commanded one 

 of the earliest expelitioiis to the Seychelles, in 1742 *.

 guste iuterruptis ; metasterno et segmeuto 1* abdominis nigris, 

 thorace subtus et segraentis posterioribus rufescenlibus, pedibus 

 aiiteunisque lufo-flavis, harum clavis baud nigricantibus. 



Long. Corp. 1'15 mm. 



Oblong-oval, with thorax rather long, its anterior margin 

 forming a curve that narrows considerably in front, and
