Linyphia hespera, sp. nov. 



Coloration essentially identical with that of L. phrygiana, with which it 

 has heretofore been confused. Cephalothorax light yellow, narrowly margined 

 with black and with a black median longitudinal line along dorsum which 

 widens clavately up the head to the eyes, this clavate portion geminate by a 

 median pale line and each half again divided at anterior end by a broad pro- 

 cess of yellow. Abdomen marked by the typical dark herringbone longitudinal 

 dorsal stripe, this often in part obliterated anteriorly. Legs yellow, typically 

 annulate as in phrygiana, w4th femora commonly minutely maculate. The 

 markings of body often reddish instead of black. The species is most readily 

 distinguished by the characters of the male palpus. The patellar apophysis is 

 similar in position and general form to that of phrygiana but differs uniformly 

 in narrowing continuously distad to the tip, where it is acute instead of being 

 clavate and rounded at the end as it is in phrygiana. The conspicuous principal 

 seta of the tibia as viewed from above is inserted towards the distal end instead 

 of near the middle; and at the base of the patella apophysis above is a seta, 

 typically as long as to longer than the apophysis, which is geniculate above its 

 base. See Fig. 19, 4. The epigynum is very similar to that of phrygiana. The 

 median lobe seems to have the distal portion a little broader and the narrow 

 isthmus a little shorter. 



Length of male type 5 mm. Length of cephalothorax 2.37 mm.; width 2.1. 

 mm. Length of tib. + pat. I 4.1 mm.; of tib. + jml. IV 2.7 mm.
