516 R. 1. POCOCK 



The anterior legs like those of /. tiiomasii , but relatively 

 smaller; the fourth and fifth or only tlie fifth segment of the 

 legs padded. 



Copulatory feet more resembling those of /. medile rraneus , 

 inasmuch as the external branch of the posterior portion is lar- 

 gely visible at the sides when the apparatus is viewed from 

 the front ; the anterior laminae are contiguous, parallel sided and 

 distally bifid, the rounded extremity of the median portion 

 appears in the bifurcation, the posterior portion is shorter than 

 the anterior, but wider, the two rami widely separated at their 

 bases converge and meet at their apices, the internal one is 

 furnished near its apex with a short hooked process. 



N° of segments 44 - 48. 



Length 31 mm., width 2.5. 



Locality: Nervi (2 c/'), Monaco (4 c/j. 



Apart from the form of the copulatory feet this species differs 

 from /. timnusii in the absence of the pale colouring on the 

 sides, in the closeness of the pore to the sulcus, in the smaller 

 number of its segments and its shorter body.

Var. nov. genuensis. 

 It is with considerable hesitation that I venture to add an- 

 other name to the list of species of lulus belonging to the 

 terreslris group. But being unable to find a name that will 

 satisfactorily fit a common Ligurian form, there does not appear 

 to be any other course open to me.
