tventum (fig. 2) Is narrow, pointed in front, and tlie terminal 

 joints of the labial palpi slightly longer than the second. 



Sacium picaultianum approaches three species which I 

 liave seen— S. bifasciation, Matth. (Madagascar), S. giiadri- 

 mncalatum, Matth. (Ceylon), and S. flaviventre, Matth. 

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

 longer in proportion, more tapering behind, much more finely 

 punctured, with the basal thoracic series much less^ distinct, 

 an<l the light marks on the elytra less sharply defined and 

 ditferently arranged. *S. quadn'miculatum and S. flaviventre 

 are both larger and differently shaped in outline, having the 

 elytra less parallel-sided and broadening out rather more 

 behind 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 

 present in S. picaullianum. The latter is quite distinct from 

 any of the three. 



'Loc. Seychelles : Sill'.ouette Island, 1908. 



Fifteen specimens. Nine were beaten from dead palm- 

 haves on the Mare aux Coclions plateau, over 1000 feet, 

 25. ix. 1908 ; five others are from the same locality, though 

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

 o£ the island, near Mont Pot-a-eaii. 



Named after Captain Lazare Picault, who commanded one 

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

 (PI.' I. figs. 4-G.) 



Oblongo-ovale, supra sat nitidum, subtiliter dense pnnctatum atque 

 pubescens, piceo-nigrum, thoracis margine anteriore late testuceo, 

 elytris fasciis '2 transversis rufo-tlavis, in sutura interdum an- 

 gti'ste iuterruptis ; metasterno et segmeiito 1" abdominis mgris, 

 thorace subtus et segmenlis posterioribus rufesceutibus, pedibus 

 aiiteunisque rufo-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 

 with elytra nearly parallel-sided, but considerably broader 

 than the thorax at their widest point ; upper surface fairly 

 shining, covered with fine, short, decumbent, pale pubescence.
