58 ARKIV FÖR ZOOLOGI. BAND 2. N:0 8. 



First Legs. — Male: They liave been very lomg, but tlie 

 distal half is wanting. Coxa terminates a litt.le in front of 

 the outer angle of the mandible. Femur is more than */b as 

 long as in the female. — Female (fig. 2 b): Slender, about 

 ^/G as long as the body. Coxa terminates somewhat behind 

 the distal angle of the mandible. Femur shghtly longer than 

 tibia. Foot slightly more than two thirds as long as tibia, 

 twelve and a half times longer than deep, and deepest at the 

 end of metatarsus (fig. 2d); second metatarsal joint a little 

 shorter than the sum of the five proximal tarsal joints; ter- 

 minal joint conspicuously longer than the sum of the two 

 proximal tarsal joints and somewhat less than half as long as 

 the whole metatarsus. 



Fourth Legs. — Male (fig.2e): Slender, elongate, somewhat 

 longer than the body; femur nearly more than three times 

 longer than deep. — Female (fig. 2 f ) : Rather slender, nearly 

 as long as the body; femur about ^/s as long as deep. 



Three posterior abdoiiiiiial Segments. — In the female of 

 usual shape and size, in the male much thicker, but the 

 specimens having been exsiccated no accurate statement as 

 to the depth can be given. In the male the terminal segment 

 (figs. 2 g and 2 h) is produced backwards into a long, somewhat 

 compressed, deep process protruding strongly a bo ve the pro- 

 ximal part of flagellum; seen from above the same segment 

 is produced forwards as a very broad, rather low, rounded 

 cone beneath the integuments of the penultimate and the 

 posterior part of the antepenultimate segment. 



Flagellum. — Male (figs. 2 g and 2 h) : The stalk is long, 

 rather compressed. The main piece is broad and not fully 

 ^/4 as deep as broad; seen from above it is somewhat longer 

 than broad, broadest a little in front of the middle and nar- 

 rowing a little towards the distal end which is broad and 

 trilobate; seen from the side the lower margin is moderately 

 convex, the upper margin irregularly curved, the distal half 

 of the main piece being more depressed from above than the 

 more proximal portion; the median terminal process is situated 

 a little higher than the lateral pair. Fig. 2 h shows two lon- 

 gitudinal areas on the proximal and one area on the distal 

 half of the upper surface set with döts which, I suppöse, are 

 marks of small setae nearly all löst. — Female: Flagellum 

 wanting in the specimens seen.
