 side of caudal end of pars cephalica but with no other markings. 

 Sternum also nearly black. Endites, labium, and chelicerae less 

 densely dusky. Legs pale, deeply ringed with black; on first and sec- 

 ond femora three rings of black, one at each end and one distad of 

 middle; on ])osterior femora these rings less developed, represented 

 by spots or sometimes not at all on the ends ; patellae mostly blackish ; 

 tibiae and metatarsi with two black annuli, one at distal end and one 

 at or proximad of middle; tarsi pale only proximally; a dark spot 

 beneath on each coxa. 



Posterior row of eyes very slightly procurved; eyes nearly equal 

 and equidistant, less than the diameter of an eye (about four-fifths) 

 apart. Anterior row of eyes a little recurved; equal and equidistant, 

 about their radius apart; protruding forward over clypeus. Area of 

 median eyes longer than wide behind, and wider behind than in front 

 in ratio 7: 6. Height of clypeus scarcely less than length of median 

 eye-area. Abdomen above black with white markings; in front of 

 middle four white spots arranged in a quadrangle ; below these spots 

 on each side a longitudinal white line, these lateral white lines united 

 across dorsum in front of spinnerets ; on each side a second line below 

 the previously mentioned one; venter with a pair of minute white 

 spots caudad of middle. 



Chelicerae transversely striate on outer face, and bearing above 

 some minute spinous points: upper margin of furrow with four teeth 

 of which the two proximal ones are much larger than the other two ; 

 the lower margin with five small and equal teeth. 



Sternum broad, subcordate; caudal end moderately narrowly ex- 

 tended between last coxae and refiexed, truncate at tij) much as in
