qiiit.o reach the snliapical pair of tho third segment. The fifth segment hears fonr 

 Intcnil hristles and a snliapieal hair, liesides a ventral jiair standing in between the 

 first lateral pair. The measurements of the mid- and hindtarsi are as follows : — 



SEodified Segments. — The eighth sternite of the t? is ver}' large, and hears 

 ahont thirty bristles, besides some short hairs. The eighth tergite bears nnmerons 

 short bristles on the back. The clasper, which is not separated from the tergite of 

 the ninth segment b}- a suture, bnt is much more strongly chitinised than the 

 portion of the segment between the clasper and the sensory jilate, is not produced 

 backwards, being oblique and bearing at the edge five long bristles (PI. XIV. 

 fig. 14, cl.). The finger is very long (f). It bears one stout, short, obtuse sj)ine at 

 the apex, and many minute hairs ou the ventral edge, there being also some hairs 

 on the dorsal edge. The manubrium (m) is very broad and curved upward apically, 

 being an inner projection of the whole lateral and dorsal portion of the ninth 

 segment, inclusive of the sensory plate. The ninth sternite (ix. st.) is club-shaped, 

 and bears some bristles at the ventral edge, as shown in the figure. This sternite 

 reminds one of that of Ilijsfrichopsi/Ua tnlpar, but the " boomerangs " of the two 

 sides appear to be completely separated from one another. The anal segment 

 is longer tiian the sensory plate, and conical, bearing numerous bristles. The 

 seventh sternite of the ? is bi-emargiiiate, the upper sinus being wide and the lower 

 small and very shallow (PI. XIV. fig. 15, vii. st.). The eighth tergite (PI. XIV. 

 fig. 15, viii. t.) is very hairy above and lielow the stigma. The apex is bisinuate. 

 The anal tergite is longer in the ? than in the c?, and very bristl\'. The anal 

 sternite is somewhat oblong, as in Piilex irrifaiis, and bears very numerous and 

 heavy bristles at the truncate apex. The stylet is subconical, being about six times 

 as long as it is basally wide. 



Length: c?, 3-4 mm. : ?, 4-2 ram.
