NE^THA SIMON. 

 Plate XVI., Fig. 7—76. 



Nesetha is the name substituted by M. Simon, in 1885, for 

 Nesera, which was preoccupied. 



The cephalothorax is high and is a Httle longer than wide, 

 the widest point being a little behind the dorsal eyes. The 

 cephalic part is inclined. The thoracic part rounds off, and 

 falls quite steeplj- a little way behind the dorsal eyes. The 

 sides are not quite vertical. 



The C|uadrangle of the eyes is one-third wider than long, 

 is but little wider behind than in front, and occupies one-half 

 of the cephalothorax. The first row of eyes is straight. The 

 eyes are all close together, and the middle are twice as large as 

 the lateral. The eyes of the second row are very minute, and 

 are placed half-way between the dorsal and lateral eyes. The 

 third row is not quite as wide as the cephalothorax at that place. 



Of this genus we have only the type species, Nesetha 

 (Neera) membrosa Simon, Araehnicles de France, Vol. III., 

 p. 200. 



NEON SIMON. 

 Plate XVI., Figs. 8—86 and 9— 9a. 



The cephalothorax is rather high. It is about one-fourth 

 longer than wide. It is narrowest in front, rounding out a lit- 

 tle behind the dorsal eyes. The sides slant inward in the ceph- 

 alic part, and outward, a little, in the thoracic. The cephalic 

 part is inclined forward ; the thoracic is nearly level for a 

 a very short distance behind the dorsal eyes and then falls not 

 very abruptly. 



The quadrangle of the eyes is one-fifth wider than 

 long, is equally wide in front and behind or a little wider be- 

 hind, and occupies a little more than one-half of the cephalo- 

 thorax. The anterior eyes are close together, and form a 

 straight row. The middle are less than twice as large as the 

 lateral. The second row is about half-wav between the first and
