HANSEN AND SÖRENSEN, THE TARTARIDES. 67 



Ceplialothorax. — Head with a more or less feebly deve- 

 loped, oblong or subcircular påle patch on each side. Cephalic 

 sternum considerably longer than broad. Second thoracic 

 tergite with a sharp longitudinal suture, but scarcely with a 

 real membranous strip. 



Palps. — Rather slender (fig. 2 a), ^/s as long as the body. 

 Trochanter (fig. 2 b) has its lower anterior part strongly pro- 

 dueed into a triangulär plate, its anterior margin is sinuate 

 and the angle measures 60°, the end itself is rather acute but 

 not produced into a process. Femur (fig. 2 b) is oblong, even 

 a little more than twice as long as deep; the lower angle is 

 feebly protruding but not rounded, its tip adorned with a 

 spine and a little longer from the distal than from the proxi- 

 mal end of the upper margin of the joint. Pateila three 

 times longer than deep, with four slender spines along its lower 

 margin. Claw very long, ^/^ as long as the upper margin of 

 tarsus. 



First Legs. — Long and slender (fig. 2 a), ""jå as long as 

 the body. Coxa terminates just at the outer angle of the 

 mandible. Femur as long as tibia. Foot short, not even half 

 as long as tibia, twelve times longer than deep, deepest bey- 

 ond the middle (fig. 2 c); second metatarsal joint only slightly 

 more than half as long as tarsus and as long as the sum of 

 the four proximal tarsal joints; terminal joint only a little 

 longer than the sum of the two proximal tarsal joints and 

 slightly more than half as long as the whole metatarsus. 



Fourth Legs. — Moderately slender and slightly longer 

 than the body. Femur two and a half times longer than deep 

 (fig. 2 d). 



Abdomen. — It is rather slender, and the segments of 

 its posterior portion are less withdrawn than in most other 

 males (figs. 2 f and 2 g). 



Flagellum. — Elongate, three times longer than deep 

 (figs. 2 f and 2 g). The stalk is rather long. The main piece 

 is somewhat broader than deep; seen from the side the pro- 

 ximal fourth of the upper margin is straight, and then it is 

 suddenly considerably lowered under an almost acute angle, 

 while the distal ^J-l of the main piece is narrowly conical; seen 

 from above the main piece is very elongate-ovate, with the 

 end not rounded but very shortly conical, and the lateral 

 margins beyond the middle slightly concave; the upper surface
