tactile setæ slightly more than one half longer than the breadth of 
the segment, rather slender, and the pubescense is very short and 
delicate; the fourth pair is almost four fifths of the last and con- 
siderably more slender. The tactile setæ of the third pair (fig. 4c) are 
slightly more than half as long as those. of the fifth pair; they increase 
considerably in thickness from the base about to the middle and are 
from thence tapering towards the acute apex; the pubescence is 
very short and fine. — The four posterior setæ on the penultimate 
segment are long, slightly tapering to rather near the end and 
from thence somewhat thickened. The setæ on the last segment 
are very long, slender, tapering, those of the longest pair a little 
more than half as long as the posterior breadth of the segment. 
Anal Segment (fig. 4b and 4d). The tergum is very broadly 
rounded behind; all three pairs of setæ are very long, slender, 
tapering, two pairs of them being about half as long as the breadth 
of the segment, while the lateral pair is somewhat longer; the setæ 
of the intermediate pair are inserted close to and- nearly in front 
of the lateral ones, while the distance between the submedian setæ 
is much longer than between a submedian and an intermediate one. 
— The styli (fig. 4d) are rather short, strongly clavate, about 
three times longer than broad; the outer margin is concave. — 
The sternum with the posterior setæ thin, cylindrical and somewhat 
shorter than the submedian dorsal pair; the lateral setæ are some- 
what more than half as leng as the submedian pair; the anterior 
setæ are nearly twice as long from each other as tbe posterior 
ones, three times: shorter than these, cylindrical and inserted near 
the base of the segment. — The anal plate is almost square, yet 
with the lateral margins as little convex and the posterior angles 
strongly rounded; from the hind margin originate two rather distant, 
short, moderately thick and somewhat diverging branches, which are 
much: shorter than the styli. 
Legs. "They are moderately short and increase somewhat in 
length 'posteriorly. The last pair (fig. 4 e) is moderately robust; 
the fémur is as long as the trochanter and slightly longer than
