any other important way from each other. In one of them 

 (probably the male sex) the anterior tlioracic angles are simple 

 and not at all produced or scarcely thickened, while in the 

 other, the angles are distinctly flattened and produced forward ; 

 this is the case in the typical specimens from Sumatra as well 

 as in those obtained both at Tenasserim and Burmah which in 

 all other respects agree with eacli other, although the colour 

 varies from dark l^rown to nearly black. S. varipes is larger 

 than most of its allies and seems to be closely allied to Argopus 

 orientaUs Baly from Japan of which it may possibly be a local 

 variety ; it differs in the stouter and shorter antennae which 

 have the 5 or 6 lower joints flavous and in the greatly dilated 

 bilobed third joint of the anterior tarsi in both sexes. For all 

 that S. varipes must be considered a somewhat doubtful species.
