BRITISH SPECIES OP PHALANGIDEA OR HARVEST MEN. 187 



Palpi spinose the inner extremity of the cubital joint produced 

 as in Platybunus into a strong apophysis. 



Eye-eminence very large and armed with a double series of long 

 divergent spines. 



Lateral pores large, sub-marginal. 



Only one species (M. insignis, Meade) is known as yet in Britain. 



Mr. Meade included P. corniger with it ; it can, however, hardly 

 be doubted but that these two species should be separated 

 generically. 



MEGABUNUS INBIGKIS. 



Megalunus insignis Meade (1855). 



Plate C, Fig. 14. 



Length of the female from 2 to 2 J lines ; length of the male 

 1J to 2 lines. The colour of this remarkable species is a whitish, 

 ashy grey, marked with black and yellow-brown. 



The normal longitudinal dorsal band on the abdomen is strongly 

 angular, yellowish brown, mottled with whitish grey, and well 

 marked by a strong, though more or less broken, black marginal 

 border. The sides, just at the junction of the upper and under 

 segments, are also strongly, but irregularly, marked with black ; 

 the underside is greyish ashy white, with some broken transverse 

 parallel brown or blackish lines marking the different segments. 

 The upper part of the cephalothorax, in continuation of the 

 abdominal dorsal band, resembles that in colour, and the caput has 

 a distinct submarginal black stripe on each side, just above the 

 lateral pores. There are 3 marginal spines on each side of the 

 cephalothorax, and a single prominent one directed forward 

 in the centre close to the fore margin of the caput. 

 This latter appears to be frequently, but not always, absent in 

 young examples, while in the adult male it is stronger, issuing 

 from a blunt tubercle. The eye-eminence is large, with a 

 constricted neck, or pedicle, and surmounted by two rows, 5 in 

 each, of long, strong, divergent, sharp-pointed, tapering spines of 

 equal length. The legs are moderately long 2, 4, 3, 1 of a dull 

 yellow-brown hue with paler annulations, which are usually more
