on each side, near the middle, and is bounded by a somewhat lighter 

 yell« w egde; behind that band appears a large reddish spot, which 

 without any determinate limits gradually fades into the ground-colour 

 of the abdomen. The cephalothorax is somewhat shorter than the pa- 

 tella and tibia of the 4 th pair together, the legs of the 1 st pair are 

 5 times as long as the cephalothorax, and the tibia of that pair 

 little more than three times as long as the patella. The mandibles 

 are as long as the tarsi of the 1 st pair. — The cephalothorax is 3 3 /, 

 millim., the 1 st pair of legs 18'/, (the tarsus 2'/. 2 millim., the me- 

 tatarsus 4'/ 4 , tibia 4 3 / s , patella l'/ 2 millim), 2 nd pair 13'/, millim., 

 3 rd pair 10 3 / 4 , 4 th pair 15 millim. (patella + tibia of 4 th pair 5 

 millim.). — All this in the d\ 



In a fullgrown ? (from Finnland) the ground-colour of the ab- 

 domen is darker, olive-green, and the spot behind the longitudinal 

 central band indistinct. In other respects the colour is precisely si- 

 milar to that of cf- The cephalothorax has, as in the cf, a lon- 

 gitudinal depression at the posterior inclination. The thighs of the 

 3 rd pair have also in this ? two spines at the apex, and those of 

 the 4 th pair one spine. (The spine-armature in Ch. nutrix is very 

 variable, as in other nearly related species; in young specimens the 

 spines on the thighs of the 3 rd and 4 th pairs are absent, sometimes 

 even on those of the 1 st pair). The cephalothorax is as long as the 

 tibia and patella of the 4 th pair together, the 1 1 pair is 3 3 / 4 times 

 the length of the cephalothorax , and its tibia not 3 times as long 

 as its patella. The mandibles are something longer than the tarsi 

 of the 1 st pair. (Cephalothorax 4 millim., 1 st pair of legs 15, 

 its tarsus 2, metatarsus 3*/ 3 , tibia 3'/ 2 , patella 1% millim; 2 ad 

 pair ir/ s , 3 rd pair 8'/ 2 , 4 th pair 13 millim., its tibia + patella 4 

 millim.; mandibles somewhat over 2 millim.). The vulva has the form 

 of a small, dark, almost semicircular elevation, which at its posterior 

 more truncated edge exhibits a small deep fovea.
