have also received from Cambridge specimens of it under the name 

 of Lyc. cambrica Blackw. This species of Blackwall's is by Walcke- 

 naer referred quite erroneously to his Lyc. allodroma (H. N. d. Ins. 

 Apt, IV, p. 395). 



The male's slender palpi have a very narrow lamina: the part 

 of it lying in front of the bulbus is as long as the part contain- 

 ing this organ ; the bulbus itself is very small , and exhibits a little 

 tooth at the outer margin, in front of the middle. The lamina is 

 somewhat shorter than the patellar and tibial joints together, the 

 tibial joint not quite double so long as it is broad, scarcely longer 

 than the patellar joint. The vulva is formed by two small rounded 

 foveae somewhat in front of the rima genitalis. The back of the ce- 

 phalothorax is strongly arched: it is longer than patella + tibia of 

 the 4 th pair, its breadth equal to the length of metatarsus + tarsus 

 of the 3 rd pair (in both sexes). The 4 th pair in cf is 3 times as 

 long as the cephalothorax, in $ a trifle shorter. 



I think it is better to refer this species to Pirata, than to 

 Trochosa (Arctosa), its cephalothorax being only thinly clothed with 

 hair, the centre eyes of the 1 st row not larger than the lateral eyes, 

 and the inferior tarsal claw armed with a tooth; by these characters 

 it is separated from Irochosa , to which genus I formerly reckoned it.
