adclitional row of shorfcer eme*, which extends only halfway 
down the sides. In the £ this addifcional row is present on the 
first tergite. The seventh tergite bears a long apical bristle on 
each side, accompanied by a very shorfc hair. The stigmata of 
the abdomen are more proximal and more dorsal in the $ than 
in the¿£, standing above the first bristle in the $ and on a level 
with or above the second in the $ on segments 3 to 7. The 
basal sternite bears only one minute ventral hair. The other 
sternites bear in the $ two or three, in the £ three or four, 
seldom five,on each side. 
Legs .—The hairs on the forecoxa are not numerous. The 
mid and liindcoxae have posteriorly at the apex two bristles, 
the upper one being the longer. There is no eomb on the 
hindcoxa. The hindfemur bear on the outerside one subventral 
bristle near the apex, and one or two lateral ones near the base, 
and on the innerside a series of eight or nine. The tibiae have 
hairs on the ventral side, and on the outer side one row of bris¬ 
tles. At the dorsal edge the tibiae bear seven pairs of bristles, 
those of the sixth pair being about the same size as those of 
the third. The long apical dorsal bristle of the foretibia rea- 
ches beyond the second tarsal segment, while the corresponding 
bristle of the hindtibia reaches to the base of the second seg¬ 
ment. The longer bristle of the fifth pair of the hindtibia is 
about three times as long as the tibia is broad in the middle. 
The measurement of the tarsal segments are:

The longest apical bristle of the first hindtarsal segment 
reaches nearly-to the middle of the third segment, and that of 
the second segment almost to the apex of the fourth 
Mod/ified Segments .—The clasper of the $ is large, and bears 
numerous hairs along the edge. The finger is very small The 
nmtli sternite is slightly dilated before the middle, obtuse at the 
apex, and bears a number of hairs along the ventral edge. 
The eiglith tergite of the $ has a few hairs above the stigma, 
about eight to ten lateral ones farther down, and a row of
