[Vol. VI, 



and the anterior margins of abdominal segments 5^ 6 and 7 res- 

 pectively bear a pair of conspicuous reddish semi-lunar patches. 

 Appendages and tail greenish, becoming reddish distally. 



Length. — 4 to 5 mm. (two specimens both with tails of the 

 form characteristic of maturity). 



5 . Cephalothorax. — Kye-spots much less conspicuous than in 

 the male on account of the paler coloration of the carapace. Other- 

 wise as in the male. 



Arms. — Almost exactly half as long as the body. As in the 

 male the lower front angle of the trochanter is slightly sharper 

 than in the corresponding sex of S. suhoculatus ; the sexual differ- 

 ences found in other parts are identical in the two species.' 



First legs (fig. i, B). — As long as body, but no longer. Femur 

 slightly longer than tibia ; foot five-sixths as long as tibia, fifteen 

 times as long as deep. Second metatarsal joint two-thirds as long

as the whole tarsus, equal to the sum of the five proximal tarsal 

 joints. Second tarsal joint scarcely as long as the third; terminal 

 tarsal joint as long as the three proximal tarsal joints and three- 

 fifths as long as the metatarsus. 



Fourth legs. — Not quite as long as body; femur little more 

 than twice as long as deep. 



Tai/.— Remarkably long and slender in adults, being eight 

 or nine times as long as broad and distinctly longer than in 

 the male. This sexual distinction in the length of the tail 



J In the female of S. lunatus the tibia of these appendages is nearly half as 

 deep as long, that of the male being slenderer. Hansen -see Hansen and Soren- 

 sen's " The Tartarides " in Arkiv for Zoologi, Bd. 2, No. 8, pp. i — 78, pis. i — vii 

 (Upsala, 1905)— does not mention this difference between the sexes of S. suhocu- 

 latus, but his figures show it to exist.
