very. shortly and more densely pubescent than the setæ of the fourth 
pair. — The three posterior pairs of setæ on the penultimate seg= 
ment long, tapering or subcylindrical, The six setæ on the last 
segment tapering, very long, almost half -as long as the posterior 
breadth of. the segment. —- The trunk is almost or comipletely 
naked. : : 
Anal. Segment (fig. 16, 1f and 1h). The tergum overreaches 
the sternum and is posteriorly produced into a short, blunt triangle; 
which is almost three times broader than long; the submedian setæ 
are inserted rather near each other, the distance: between them 
being much shorter than between the submedian and the interme- 
diate pairs; the- submedian setæ are always conspicuously shorter 
than the two other pairs; these are inserted near each other, those 
of the lateral pair are slightly longer than the intermediate pair 
and scarcely half as long as the breadth. of the segment; all three 
påirs are moderately pubescent. — The styli are rather thick, 
pubescent, blunt ;or acute setæ which are about half as long as the 
submedian dorsal setæ. — The sternum with its posterior setæ 
more than three times longer than the styli, — The anal plate, 
which generally has its basal part retracted and overreached by 
the sternum, is large, Conspiciously or even considerably broader 
than long and rounded at the: base; Posteriorly: it is produced. into 
four. branches situated in the: same plane; the inner 'branches are 
rather near: each other, cylindrical. or tapering, "delicately pubescent 
and almost twice longer than the outer branches, which are tapering 
with acute end - and feebly "or moderately diverging. — The seg- 
ment and the anal plate are naked. ' 
Legs.…They are long and increase much in length postériorly. 
The last pair. (fig. 1g)- is very long og. slender; the: femur about 
twice;.as, long as the trochanter and Somewhat shorter than the 
elongate tibia; which is at least three times longer than thick; the 
tarsus. is. almost one half longer than the tibia and distally slender. 
The. hairs on the coxa and. trochanter are biramous;.the setæ on
