Very similar to S. HuJJmuH, but Iiirgcj', of durkor colour, 

 the elytra ulmoHt quite dentitute of pubeHcence, and not 

 quite HO densely punctate ; the nine or ten Heriew 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 distiuct punctuation 

 of the femora leaves no doubt the species is distinct.

 at the time not distinguished from it by me.

Extremely similar to *S'. lonf/vlus, but with much 

 larger antennal club and longer legs, and also with the 

 jjalpi and base of the antenna; darker ; the elongation of 

 the legs is accompanied by a considerably greater 

 development of the claws and their lobe, so that the 

 species approximates much to the genus Jiijgmodus. 



Greymouth (Helms) ; one example sent with >S'. 

 Irmgalus, and not distinguished at the time from it 

 by me.

Head blackiBh, with the epiBtome indefirtitely broadly pale,
