HASARIUS (e. SIMON). 

 Plate V, figs. 1-lb. 



The cephalotliorax is rather high and moderately long. 

 The cephalic part is slightly inclined forward ; the thoracic 

 falls very little, or not at all, for about half its length and 

 then more abruptly. It is more or less contracted in front, 

 and widens out behind the dorsal eyes. The sides of the 

 cephalic part are sometimes nearly vertical ; in the thoracic 

 they widen out distinctly from above to the lower edge. The 

 quadrangle of the eyes is equally wide in front and behind, 

 or a little wider in front, is from one-fourth to one-third 

 wider than long and occupies about two-fifths of the cephalo- 

 tliorax. The anterior eyes form a straight or slightly curved 

 row, the middle being subtouching or a little separated and less 

 than twice as large as the lateral, which are more widely re- 

 moved from them. The second row is about half-way between 

 the first and the third ; the third row is nearly or quite as wide 

 as the cephalothorax at that place. 



Hasarim belongs to the group of genera of which Phidip- 

 pus is tlie representative, as being the strongest and most widely 

 known. It has no very strongly marked characteristics, but it 

 includes a considerable number of species, which are of medium 

 size, or larger, and are widely distributed. It is, perhaps, most 

 closely related to Plexippv^, but is readily distinguished from 

 that genus by the longer cephalic part and by the more nearly 

 parallel sides of the cephalothorax. We give generic drawings 

 of the type species, H. Adansonii.
