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 completely 
naked. 
Anal Segment (fig. le, If and lh). 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 
pairs 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 posteriorly. 
The last pair (fig. 1 g) is very long og siender; 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 siender. 
The hairs on the coxa and trochanter are biramous; the setæ on
