174 BRITISH SPECIES OF PHALANGIDEA OR HARVEST MEN. 



subdivided by immovable or " false" articulations. Palpi not very 

 long, simple, and ending with a denticulated claw. 



In this genus the result of the crushing up together of the 

 thorax and anterior portions of structure, mouthparts, &c., is very 

 observable, the abdomen and basal joints of the legs appearing to 

 have had it all their own way. Only two species have yet been 

 observed in Britain. 



LlOBUNUM ROTUNDUM. 



PJialangium rotundwn Latr. (1791). 



Leiobunus rotundus Meade (1855). 



PI. B, fig. 6. 



Length of the female 2 to 2J lines, of the male 1J to 2 lines. 



The female has the cephalothorax and abdomen of a somewhat 

 oblong-oval form, and the epidermis is minutely squamose ; it is of a 

 pale brownish-yellow colour, the sides and forepart of the cephalo- 

 thorax dark brown, and a broad oblong marking (rather broadest 

 behind), on the upper side of the abdomen, as well as the hinder 

 part of the same are also dark brown. The brown marking on the 

 abdomen is spotted with white. The paler markings on the abdo- 

 men are often of a bright silvery hue. The legs are of great length 

 and tenuity, their colour is brown, or yellow-brown, of a more 

 or less deep hue according to age. The femora are furnished with 

 minute denticulations. The exinguinal joints are generally of a 

 darker colour than the rest. The eye-eminence is small, situated 

 nearer to the hinder than to the fore extremity of the cephalothorax. 

 It is quite smooth, though with a central longitudinal groove or 

 indentation which separates the eyes ; these are each encircled with 

 a dark brown rim. Just below the fore margin of the caput and 

 above the base of the falces, are two small nearly contiguous blunt 

 projecting points. The male is much smaller, as well as shorter 

 and rounder in form than the female, and the legs are longer. It 

 is usually of a deep reddish brown colour without any markings 

 traceable, and the legs are also darker coloured. 



Generally distributed and found abundantly towards the end of 

 summer and in early autumn in most woody and wild places runn-
