In the structure of the gonopods similar in general to 
S. naresi, but differing in numerous minor details. The 
anterior median plate is larger, with the upper arms less 
strongly divergent and shorter relatively to the distal 
undivided plate; the latter is distally similarly truncate or 
very gently convex, but the sides are less divergent and more 
evenly convex towards the arms ; the free mesal end of outer 
lobe of arms projectivg more directly distad, close to mesal 
edges of arms. ‘lhe anterior or basal division of the anterior 
gonopods is of more nearly uniform width, the distal end 
being broader and the lower middle part narrower. 
The general colour black. Hach metazonite above is 
bordered caudally with ferruginous, the ferruginous stripe 
widening down the side and below, embracing the entire 
metazonite, the black of the prozonite becoming lighter at 
the same time from the inclusion of light dots. Legs and 
antenne fulvous to pale ferruginous. 
Antenne short, a little clavate. Eyes trapeziform, with 
the base caudad and convex, less than twice their diameter 
apart. Surface of head smooth and shining. Sulcus widely 
interrupted in the frontal region as usual. 
Collum strongly narrowed below on each side as usual ; 
but the lateral edge straight, not rounded, the caudo-lateral 
angle rectangular, the antero-lateral obtuse but not rounded, 
or but little so. 
Segments with no distinct median transverse suture, the 
position of the latter occupied by a weak furrow, along which 
above, in the typical segments, is a series of sharply 
impressed circular and horseshoe-shaped marks, which 
continue also in a series for some distance below the pore. 
On the metazonite above are sparse and very small semicir- 
cular or crescentic impressed lines. The metazonite crossed 
below by the usual striz, wholly smooth above. In the 
anterior segments the prozonites below the pore marked
