outer lobe of the suborbital margin is 

 triangular and blunt, more advanced 

 than outer angle of orbit but not con- 

 spicuously so; the inner lobe is small, 

 spiniform, acute, separated by a very 

 wide, deep sinus from the outer tooth, 

 and quite invisible except in front 

 view, being hidden by the large 

 pterygostomian lobe, which is nearly 

 as advanced as the basal joint of the 

 antenna; outer sinus of lower orbit 

 triangular. 



The first leg reaches to end of 

 merus of second, the third to end of 

 carpus of second, second about three 

 and one-half times as long as width of 

 carapace; merus joints more cylindri-

cal than in cursor and with posterior 

 margin almost unarmed except at 

 distal end; carpal joints cylindrical, 

 not flattened and angled. 



Crest of fifth abdominal segment 

 of female obsolescent; first three seg- 

 ments of male abdomen cristate ; fifth 

 segment with side margins very ob- 

 tusely angled. 



Measurements. Female (9735), 

 length of carapace 10.G, width of same 

 16, length of second leg 57 mm. 



Variations. In smaller specimens 

 the lateral sinuses of the front are 

 shallower, the longitudinal grooves 

 which run back from the inner orbital 

 sinus and meet the transverse gastro- 

 cardiac groove are deeper, the few 

 largest tubercles stand out more 

 prominently than in larger specimens.
