BRITISH SPECIES OF FALSE-SCORPIONS, 217 



KONCUS CAMBRIDGII. PI. B, fig. 9. 



Syn : Roncus Cambridgii, L. Koch. Darst. Eur. 



Chernet, p. 45 (1873). 



Obisium lubricum, E. Simon. Arachn. de France, 

 torn. 7, p. 63 (1879). 



Length slightly over 1 line. 



The cephalothorax is roundly truncated before; of a yellow-brown 

 colour slightly tinged with reddish. The palpi and falces much more 

 strongly tinged with red ; the claws of the pincers reddish ; the 

 plates of the abdominal segments dull brownish and the legs of a 

 paler hue. The eyes are small, round, and rather more than a 

 diameter's distance from the fore-margin of the caput. 



The palpi are of moderate length, rather strong, the humeral and 

 cubital joints as nearly as possible equal in length, the latter has a 

 very distinct neck or stem at the base, abruptly enlarging into a 

 somewhat roundish oval form in front. The claws of the pincers 

 are slightly curved and equal to the bulb in length. The hairs 

 with which this species is clothed are few, fine, and simple. 



This is a rather scarce species ; I have only found it myself 

 occasionally among moss and dead leaves in woods at Bloxworth, 

 but a specimen in the British Museum was found on Dartmoor. 

 It does not appear to have been met with in Germany, and but 

 sparingly in France, South Italy, Austria, Algeria, and Morocco. 

 It was described in 1873 as a new species by Dr. Ludwig Koch 

 from specimens sent to him by myself from Bloxworth. M. Simon 

 by some oversight has this species in his Araneides de France, 

 under the specific name of lubricum, while he gives the name 

 Cambridgii to R. lubricus, L. Koch.
