distinct ; there is a well-marked pallid humeral spot ; the scutellnm 

 is sparingly and finely punctate.

1818. S. obeSUS, n.s. (Sharp; Trans. Ent. Soc. Loud., 

 1884, p. 469.) Breviter ovalis, latus, sat convexus, crebre punc- 

 tatus, nigricans, elytrorum margins externo piceo, prothoracis 

 lateribus argute testaceis, pedibus piceis tarsis dilutioribus, anten- 

 narum basi palpisque sordide testaceis ; femoribus posterioribus 

 subtus dense punctate- pubescent ibus, 



Long., 6-|mm. ; lat., 4mm. 



Very similar to S. suffusus, but larger, of darker colour, the 

 elytra almost quite destitute of pubescence, and not quite so densely 

 punctate ; the nine or ten series of punctures rather more distinct, 

 and with no pallid humeral spot ; the club of the antenna also is 

 more elongate, and the very dense and distinct punctuation of the 

 femora leaves no doubt the species is distinct. 



Greymouth. Helms. 



1819. S. antennatus, n.s. (Sharp; Trans. Ent. Soc. Lond., 

 1884, p. 469.) Ovalis, sat convexus, nitidus, piceus, limbo dilutiore, 

 pedibus testaceis, antennarum basi palpisque fusco-testaceis ; crebre 

 punctatus, et in elytra profunde seriatim punctatus, seriebus pos- 

 tice profundioribus ; femora posteriora glabra. 



Long., 6mm.; lat., 3Jmm. 



Extremely similar to S. longulus, but with much larger antennal 

 club and longer legs, and also with the palpi and base of the an- 

 tennae darker ; the elongation of the legs is accompanied by a con- 

 siderably greater development of the claws and their lobe, so that 

 the species approximates much to the genus Rygmodus.

1820. S." longulus, n.s. (Sharp; Trans. Ent. Soc. Lond., 

 1884, p. 469.) Ovalis. sat convexus, nitidus, piceus, limbo dilutiore, 

 antennarum basi, palpis pedibusque testaceis ; crebre punctatus et 

 in elytra profunde seriatim punctatus, seriebus postice profundiori- 

 bus, femora posteriora glabra. 



Long., 6mm. ; lat., 3^mm. 



Head blackish, with the epistome indefinitely broadly pale, 

 rather closely and finely punctate, very shining. Thorax also Very 

 shining, moderately closely and coarsely punctate, the punctuation 

 more effaced on the disc than at the sides. Scutellum almost im- 

 punctate. Elytra coarsely punctate, and with very distinct series of 

 punctures. 



Greymouth. Helms. I have only two examples, both in bad 

 preservation.
