r? ? . Foretibia armed with some spines at and near the end. Hindtibia a little 

 longer (in S h mm., in ? H mm.) than, long terminal spur barely two-thirds the 

 length of, the first tarsal segment. 



c?. The eighth abdominal sternite is deeply sinuate mesially, the edge of the 

 segment is very oblique, each side very slightly and almost evenly convex from 

 the most dorsal jioint to the bottom of the sinus. The hnrpe is the most peculiar 

 in the genus (PI. XXXI. f. 13), it being connected with thf ])ody of the clasper only 

 at the base, as shown in the figure, which represents the clasper and harpe in a 

 ventral view ; the Iiarpe is n very long, slightly twisted process, of which tlie 

 apical third is rather suddenly uarrowed and gently bent dorsad ; the two harpes 

 lying across each other, as shown in the figure. The penis-sheath (PI. XXX. f 21) 

 is armed apically with a [irocess which is concave ventrally and armed with some 

 teeth at the ventral edge ; the jjrocess is apparently movable, being joined to the 

 penis-sheath : ventrally there is another armature consisting of an elongate, oblique 

 patch of teeth a little before the distal edge of the sheath. The tenth tergite (the 

 supra-anal hook) is very difterent from that of the other Oxymnhuhix, where it is 

 uniform in structure. In ca/ie.^ceti/i the tenth tergite is longer than elsewhere in 

 the genus, broad, mesially incised at the end (PI. XXIII. f. 20), and the lateral 

 edges are turned ventrad a little, the upper surface of the tergite being somewhat 

 convex. In a lateral view (PI. XXIII. f. 19) the tenth tergite is slightly curved 

 ventrad. The tenth sternite (PI. XXIII. f. 20) is in a ventral view triangular, 

 sharply pointed ; in a lateral view (PI. XXIII. f 10) it resembles somewhat tlie 

 blade of a knife, the mesial line of the sternite being raised into a thin but 

 comjiaratively high carina, which is minutely denticulate. The membrane just 

 above the anus (PI. XXIII. f 10. 20) is more strongly chitinised forming a short, 

 smooth, brown bar. 



?. Eighth tergite (PI. XV. f. 9) long, truncate, /lot sinuate. Vaginal plate 

 (PI. XV. f. S) with a sinuate antevaginal ridge ; at each side of the orifice there 

 is a pointed curved process which has a rather close resemblance to the armature 

 of Poh/pti/cliiiii pyqarqa ; postvaginal part of ))]ate small, transversely folded.
