Genus Ariamne (Thor.)= Ariadne (Do\.)=Proffnatha 

 (Camb. MS.). 



Ariamne longicaudata, sp. nov. (Plate XIV. fig. 11a.) 



Male adult, length 2| lines. 



The ceplialothorax is oval and of a rather flattened form ; the 

 general profile-line is level ; but there is a deepish transverse dip or 

 depression between the caput and thorax, which gives an appear- 

 ance of eminence to the former ; it is of a dull yellow colour, and has 

 the margins, as well as the hinder part of the caput, broadly marked 

 with blackish brown ; besides which, there are two patches, or bars, 

 on the clypeus, one opposite to each fore central eye, of the same 

 colour ; the clypeus is sharply impressed immediately below the eyes, 

 but projects greatly thence to the falces, and considerably exceeds 

 in height half the facial space. 



The eyes are grouped on the highest portion of the caput ; four 

 (the largest) form a large square near its summit ; and close to each 

 of the two hinder eyes of the square is a lateral pair, the eyes of 

 which are contiguous to each other, the hinder one being close to 

 the hinder eye of the square on its side ; the foremost eye of each 

 lateral pair is minute, the smallest of the eight ; the two foremost 

 of the square are of a brownish-yellow hue, but appear nearly black, 

 owing to the black spots on which they are placed ; the rest are 

 pearly white. 



The legs are very long and exceedingly slender ; their relative 

 length 4, 1, 2, 3, and furnished with fine hairs ; they are of a pale yel- 

 low colour, suffused with a deeper hue at the joints ; the terminal 

 tarsal claws are very minute, and (as far as I could ascertain) three 

 in number. 



The palpi are similar in colour to the legs, long, slender, and fur- 

 nished with longish pale hairs ; the radial is longer than the cubital 

 joint, both are slightly clavate ; the digital joint is small, and the 

 palpal organs simple and inconspicuous ; they have a small pro- 

 minent, curved, corneous sharp-pointed spine near their extremity,
