The tergum has a median almost semicircular' projection of the 
hind margin; the submedian setæ are placed somewhat in front of 
this margin, they are a- little shorter than the distance between 
them and scarcely one fourth as long as the breadth of the tergum ; 
the intermediate setæ are shorter than the submedian ones, and their 
distance from these about equal to their own length; the lateral 
setæ are somewhat longer than the submedian pair. — The styli 
are almost as long as the submedian setæ and shaped as clavate 
hairs. — The sternum with the posterior setæ more than three 
times longer than the submedian pair, which is about as long as 
the lateral ventral setæ. — The anal plate is about square with 
the lateral margins slightly convex and continued as the outer mar- 
gins of a pair of branches, which are parallel, acute and a little 
shorter than the plate; the hind margin between the outer branches 
is rather long and has two quite: rudimentary branches somewhat 
distant from each other. 
Legs.… They are moderately short and not very robust. The 
last pair (fig. 5 e) with the femur somewhat shorter than the tro- 
chanter, scarcely longer than thick and not one half shorter than 
the tibia, which is almost twice as long as thick. The tarsus is 
somewhat longer -than the tibia. The hairs on coxa and trochanter 
åre simple, clavate; the seta on the tibia two and a half times 
shorter than the joint. 
Copulatory Organs (fig. 5f). They are rather long,  slightly 
more than twice as long as thick; seen from' the side the front 
margin is nearly straight in the basal half and distally rather con- 
vex, while the posterior margin is sinuate, the apex is: not veese 
Scarcely acute. 
Length. The single specimen, which is normally extended, 
measures "54 mm.
