bristles being situated in the centre of the segment and there being no antepygidial 

 bristles. The bristles of the sternites are long, the numbers being as follows on 

 the two sides together : in c? 2, fi, 8, 8, 8, 7 ; and in ? 2, 0, 11, 10, 10, sternites 

 iii. to vi. of the ? bearing on each side one bristle in front of the row, and 

 sternite vii. having altogether seventeen bristles. The pygidinm is strongly 

 convex, projecting backwards. 



Le(/s. — Thesubapical sinus at the hind-side of the mid-coxa is semicircular, the 

 angle above it being but slightly rounded ofi' and the hindmargiu of the mid-coxa 

 almost straight; the apical lobe of the mid-coxa is large, and there are two bristles 

 on its base at some distance from the sinus. The hind-coxa bears a patch of about 

 ten short spiniform bristles on the inside at the apical third, those bristles of this 

 patch which are nearest the anterior edge of the coxa being longer and thinner, 

 and those placed between the jiatch and the apex of the coxa being normal in 

 shape. The posterior subapical sinus of the hind-coxa is shallower than in the 

 mid-coxa, and the apical lobe longer. This lobe bears three long bristles. The 

 femora are slender, the proportional length and width of the hind-femur being 21 

 and 8 respectively, and bear one bristle on the inner lateral surface towards the 

 base. There are two subapical ventral bristles on the outside of the hind-femur 

 and one on the inside, all long and slender. The tibiae have six dorsal notches 

 inclusive of the apical one, each bearing a pair of divergent bristles, there being 

 sometimes an additional solitary dorsal bristle between the fourth and fifth pairs 

 of the hiud-tibia. A row of six lateral bristles on the outer surface corresponds 

 with the dorsal notches. The longest ventral apical bristle of the raid-tibia and 

 the longest dorsal apical bristle of the hiud-tibia reach far beyond the apex of the 

 first tarsal segment. The bristles of the tibiae and those of the hind-tarsus are 

 very strong. The longest one of the first hind-tarsal segment extends beyond the 

 apex of the second segment and the corresponding bristle of the second reaches 

 a little beyond the fourth. The mid -tarsi of the S are broken. The tarsal segments 

 measure : 



(S hind-tarsus 33, 31, 13, 10, 19. 



? mid-tarsus 18, 16, 9, 7, 18 ; hind-tarsus 40, 24, 14, 11, 20. 



The fourth hind-tarsal segment is twice as long as it is broad. The four ventral 

 pairs of bristles of the fifth segment are (juite lateral, the first pair not being moved 

 on to the ventral surface. 



Moi/ified sfgiiifiits. — S. The eighth tergite bears no bristles. The cavity of the 

 stigma is large, nearly horizontal, and almost gradually narrows inwards. The 

 eighth sternite is large and has a transverse row of eight bristles on the two sides 

 together. The clasper is longer than it is broad, with the dorsal and ventral 

 margins almost parallel (PI. XI. fig. 12), the distal margin slanting upwards, the 

 lower angle quite effaced and the upper one extended to near the apex of the 

 " finger " (PI. XI. fig. 1.5, P). The clasper bears one moderately strong bristle below 

 the insertion of the finger, a small and thin one above the insertion, and several 

 other thin ones at and near the apex of the process P. Moreover, there are several 

 larger bristles at the dorsal margin, one of which is particularly strong and long. 

 The manubrium (M) is broad i)ro.ximally and narrow distally, its ventral margin 

 being moderately convex. The finger (PI. XI. fig. 15, F) is narrow, evenly curved, 

 somewhat tapering, with the distal side convex. The bristles are all thin and 

 short, the one placed in the centre of the distal surface being the longest. The 

 ninth sternite is boomerang-shaped ; the ventral, horizontal portion is particularly
