ARA^EIDEA. 93 



The eyes occupy an area longer than broad ; the front row is shorter than the middle 

 one, and its two central eyes are placed on a slight prominence, and are larger than the lateral 

 ones ; the four being very nearly, if not quite, equally separated from each other, and the 

 height of the clypeus is greater than the diameter of one of the fore central eyes, but not as 

 much as two diameters. The eyes of the middle row are much larger than those of the hinder 

 one, and, with them, form a square whose posterior side is the shortest. 



The legs are long, attenuated at the extremities, of a deep reddish-brown colour, fur- 

 nished with hairs and spines, and clothed with greyish pubescence. 



The palpi are rather long and strong, and similar in colour to the legs ; the radial and 

 cubital joints are of equal length ; the digital joint is of tolerable size, and nearly equal in 

 length to the radial and cubital joints together ; it is oval behind and rather attenuate before. 

 The palpal organs are not very complex, but from the middle there projects a short but pro- 

 minent process with three prominent divergent points, the middle one being the longest and 

 strongest. Like the legs, the palpi are covered more or less with greyish hairs. 



Thefalces are moderately long, but not very strong, slightly divergent and directed 

 backwards : their colour is deep rich reddish black-brown, with a reddish-yellow broad longi- 

 tudinal stripe on the inner side at the fore extremity. 



The maxilla are reddish-brown, pale-yellowish at the extremities and on the inner side. 



The labium is similar to the maxillae in colour, with a pale-yellowish apex. 



The sternum is oval and of a deep shining reddish-brown colour. 



The abdomen is of a blackish-brown hue, with the normal longitudinal marking on the 

 fore half of the upper side, and a series of succeeding angular bars of an obscure brownish 

 red; the whole is thickly clothed (especially along the median portion of the upper side) with 

 greyish hairs, forming there a broad, longitudinal grey band, emitting some short lateral pro- 

 minent lines on each side of the hinder part. 



Hab. Hills between Sirikol and Aktalla, between the 8th and 18th of May 1874. 



117. LTCOSA FLAVIDA, sp. n. 



Adult female : length 2| lines. 



The cephalothorax is of a pale-yellow colour, with two broad, longitudinal, lateral yel- 

 low-brown bands reaching from the fore to the hinder margin, and thinly clothed with greyish 

 hairs ; the height of the clypeus is no more than equal to the diameter of one of the fore 

 central eyes. 



The eyes are in the ordinary position, on large black spots ; the whole of the fore part 

 however, of the ocular area is more or less black. The front row is shorter than the middle 

 one ; its two central eyes are larger than the laterals, and the interval between them is greater 

 than that between each and the lateral eyes next to it. The eyes of the middle row are very 

 large, and separated from each other by no more than one diameter ; this interval being but 

 little less than that which separates each from the posterior eye opposite to it ; the four 

 hinder eyes form a square whose posterior side is longest and anterior one slightly the shortest. 



The legs are moderately long and not very strong ; their relative length is 4, 1, 2, 3, and 

 they are of a pale yellow colour, rather paler than the cephalothorax, armed with spines and 

 furnished thinly with hairs.
