132 ON NEW AND RARE BRITISH ARACHNIDA. 



rather produced in the form of an obtuse projection ; besides 

 a few ordinary hairs the cubital joint has a single one a little 

 stronger than the rest in front, and the radial has a curved 

 one much stronger than the rest towards its extremity on the 

 outer side. The digital joints are of moderate size. The 

 palpal organs are highly developed, complex, and very 

 distinctive ; their form and structure can be best seen and 

 understood from the figure on the plate. 



The jalces are of moderate size, vertical, and tapering, 

 and, with the maxillce, which appear to be of normal form, 

 similar in colour to the Cephalothorax. 



Sternum heart-shaped ; obtusely drawn out at its hinder 

 extremity, which is truncate. Colour yellowish brown. 



Abdomen, rather elongate-oblong, a little narrowest in 

 front, and moderately convex above, of a uniform dull, pale, 

 whitish hue (which would probably have become darker by 

 age), furnished thinly with hairs, of which a few scattered 

 over the upper side are very much longer than the others, 

 prominent and black. The under side of the abdomen is 

 suffused Avith sooty black. 



Found among dwarf herbage in a wood at Bloxworth on 

 the 18th of May, 1912. 



Maso gallica, Sim. p. 117. 



This species differs a little in size from the closely allied 

 form, M. Sundevallii, Westr., but may easily be distinguished 

 by the clavate hairs on the palpi of the male. These are, 

 some of them at the fore extremity of the upper side of the 

 radial joint and three others at the extremitj^ of a conical 

 projection near the base on the upper side of the digital joint. 

 The genital aperture of the female also differs from that of 

 M. Sundevallii. This latter species is widely distributed and 

 common in some localities, but M. gallica has as yet only been 

 recorded from Wicken Fen.
