156 E. ELLTNGSEN ON 



Chelifer nodosus, Schrank. 



England: South Norwood (London), August, 1906, taken by 

 Mr. H. Hill on a fly's leg in a house ; two specimens, <$ and $ • 

 Louth (Lincolnshire), August, 1906, taken on a fly's leg in a 

 grocer's shop by Mr. J. Larder ; one $ . 



This species and the foregoing have great affinity to each other, 

 but they may be distinguished b}^ the following particulars : 



Chelifer Chyzeri. Cephalothorax granulated, abdomen rather 

 coarsely sha greened ; the protuberances of the trochanter placed 

 on the outer edges, both of them thus showing backwards ; the 

 lower protuberance very distinct (in <$ both protuberances are 

 somewhat pointed, in $ the upper is rounded) ; tibia and hand 

 more granulated, the fingers proportionally a little longer and 

 the stalk of the tibia somewhat longer than in C. nodosus. 



Chelifer nodosus. Cephalothorax smooth and glossy, the 

 surface behind the transverse groove may, however, be slightly 

 granulated, though not so strongly as in the other species. 

 Abdomen very minutely shagreened. Trochanter with the 

 hinder protuberance wevy little pronounced, the upper pro- 

 tuberance placed distinctly on the upper surface (rounded in 

 $ ). Tibia and hand, particularly above and below, smooth 

 and shining. 



The former species seems to be found always out-of-doors, 

 while the latter is at least often found in houses, and often 

 fixed to the legs of flies. 



Chelifer cyrneus, L. Koch. 

 I have seen one $ from Sherwood Forest (Nottinghamshire). 



Chelifer cimicoides, Fabr. 



I have seen specimens from Burnham Beeches (Buckingham- 

 shire). 



Chelifer dubius, Cambridge.
