Flag-elluin. — Male (figs. 3 i and 3 k): Moderately small, 

 but deep and broad in proportion to its length. The stalk 

 is rather long, decidedly compressed. Seen from above, the 

 main piece is a little longer than broad, subovate, with more 

 t han half of the lateral margins straight or even shghtly 

 concave and very converging, the posterior end is cut off 

 nearly transversely from each side so that a very obtuse ter- 

 minal angle is formed. When the flagellum is seen from the 

 side, its whole lower margin is considerably convex, the upper 

 margin shows a deep and broad triangulär incision at some 

 distance from the end, and the yjortion in front of this de- 

 pression is strongly vaulted. Two of the setie preserved are 

 very long. one of them nearly -/a as long as flagellum. — 

 Female: Flagellum (fig. 31) somewhat shorter than in the 

 male, a little more than four and a half times longer than 

 deep, three-jointed, third joint almost twice as long as the 

 sum of the two others. Several of the setse are very long, 

 one pair even more than ^/4 as long as flagellum. 



Measuremeiits. — Body a" ^^.^i, $ 6. o mm.; palps o" 2.8, 

 9 2.5 mm.; first legs ö" H--^, 9 7.9 mm.; fourth legs (/ 7.7, 

 9 6.2 mm. 



Colour. — Palps and antenna? bright red, the latter darker 

 in front; upper surface of cephalothorax dark olive green, 

 more or less reddish anteriorly; upper surface of abdomen, 

 and femora, patelloe and tibise of the three posterior pairs of 

 legs brownish green — especially the femora of fourth pair 

 dark green — with the edgings at the articulations bright 

 red; first pair of legs and distal portion of the three other 

 pairs light brownish green; lower surface of the body light 

 yellowish. 



Differences accordiiig to Age. — Of the smallest specimen 

 the body measures 3.5 and the first pair of legs 5.2 mm.; 

 these legs are thus nearly ^/2 as long as the body and propor- 

 tionately longer than in the adult female. Palps a little more 

 robust than in the adult female, the angle of trochanter a 

 little more rounded, patella slightly more than two and a half 

 times longer than deep. First legs slightly thicker than in 

 the adult female; foot about ^/i as long as tibia, eleven times 

 longer than deep (fig. 1 c); second metatarsal joint as long 

 as the sum of the two proximal tarsal joints, and a little less 

 than half as long as the Avhole metatarsus. Femur of fourth
