KBT. O. PICKAED-CAMBKIDQE ON 



[June 7, 



les Bains, near tbe end of July 1897, and again in August 1896. 

 rrom this sex being not rare under stones, mostly with their egg- 

 sacs, and no males being seen, it is probable that the season for the 

 latter sex had passed. 



LxcosA (Pabdosa) biparia C. L. Koch. (Figs. 3, 4.) 



Adult male, length 2| lines (nearly 5 mm.). 



In form, size, colours, and markings this spider closely resembles 

 L. pullata 01k., so much so that M. Simon, to whom I submitted 

 both sexes for examination, returned them to me under that name. 

 Had M. Simon, however, closely inspected the male palpi and the 

 female genital organs he would at once have seen their great 

 difference from those of L. pullata.

Fig. 4. — „ ,, (<S)'- portion of palpus and palpal organs. 



CepTialothorax deep brown, with three longitudinal yellow stripes 

 or narrow bauds — a central, two lateral, and a submarginal : the 

 lateral stripes are rather irregular ; the central stripe terminates 

 at tbe beginning of the ocular area, and is rather broader in the 

 middle than at the ends. Ocular area black. 



Legs yellow, the femora more or less clouded and marked irregu- 

 larly with deep brown and blackish ; those of the fourth pair 

 longest. 



Palpi black, the radial and digital joints thickly clothed with 

 short strong hairs ; those of the outer side of the digital joint 

 shortest and of uniform length. This joint is rather longer than 

 the radial and cubital joints together, narrow-oval, and ending with 

 a strongisb, curved, nail-like claw. Tbe palpal organs are highly 

 developed. From the usual large basal lobe a long, strong, broad, 

 curved, spiny, tapering, somewhat flat strap-like process on the inner 

 side curves over obliquely to the outer side, a little beyond which its 

 broadly and a little obliquely obtuse point projects freely; this point
