BRITISH SPECIES OP PHALANGIDEA OR HARVEST MEN. 179 



dependent as well on the age of the individual as on the season. 

 The extremity of the genital plate is wider than in the female and 

 more squarely truncate. The exposed sides of the coxse of the 

 legs, chiefly of the anterior pairs, are also often furnished with 

 small tuberculous teeth. 



This species is abundant and generally distributed in woods, 

 waste grounds, and hedgerows, &c., becoming adult in summer and 

 early autumn. It is the one to which, probably, the trivial name 

 of Harvest-men peculiarly attaches, being most common in harvest 

 time. I find immature individuals of a peculiarly ashy and hoary 

 hue, very common on the grassy flowery flats near the Chesil Beach, 

 Portland, early in the summer, so much so that I have at times 

 suspected them to belong to a distinct species, though I have not 

 yet succeeded in obtaining corresponding adults, which would alone 

 prove either their distinctness, or their identity with the present 

 species. The only adults I have met with there have been of the 

 ordinary P. opilio type. I have not, however, had much oppor- 

 tunity for working in that locality during the later summer and 

 autumn seasons. 



PHALANGIUM PARIETINUM. 



Plialangium parietinum Degeer (1778), Meade (1855). 

 PI. B, fig. 9, and PI. A, fig. 6. 



As large or often rather larger than P. opilio. 



Length of the female 4 to 5 lines, male 3 to 4 lines. 



The form of the body in this species is an elongate-oval, the 

 abdomen being pinched in laterally near its fore extremity. The 

 ceplialotlwrax is of a yellowish colour mottled with whitish, and 

 the abdomen is of a general pale whitish-grey and yellowish and 

 brown mottled appearance, with an indistinct whitish longitudinal 

 central line or mark sometimes present. The under side of the 

 abdomen and the coxal joints of the legs are also more or less 

 spotted and mottled with brown or blackish ; the coxal markings 

 are usually elongate. The broad normal angulated band on the 

 upper side of the abdomen is (though sometimes obsolete) usually 

 very faintly marked by being a little darker than the rest of the
