So far as I have determined, tibia + patella of fourth legs of the male 

 in Eastern specimens of helluo is longer than tibia + patella of first pair 

 or sometimes, iii large specimens, of the same length, whereas the 

 reverse is seen to be true in grandis. But as the relative lengths of 

 these two pairs of joints varies in helluo and apparently with the size 

 of the individual, the increased relative length of tibia + patella of the 

 first pair, and in fact of the entire first leg, may not be of much signifi- 

 cance. The agreement between helluo and grandis is thus close excepting 

 in color and size, and it might therefore be more proper to place the 

 latter as a variety under the former.

(Trans. Am. Ent. Soc, XXIII, p. 72.) 



Female.— Cephalothorax with a median light colored longitudinal 

 band which anteriorly is geminated and is nearly as wide as the eye 

 area, with on each side a narrow supramarginal light brown stripe 

 which is discontinuous, being broken into four or more parts. Cheli- 

 cerw dark reddish brown. Sternum brown, with a black mark along 

 middle. Legs brown, with the distal joints darker, blackish brown; 

 femora above with some rather obscure black marks. Cox(e brown, all 

 with a black, very distinct line along front face. Abdomen above 

 black; sides and lateral part of venter blackish over a yellow ground, 

 mixed yellow and black; venter yellow. 



Cephalothorax low, its dorsal line straight and but slightly slanting 

 from the third eye row to the posterior dechvity, which is short and 

 steep. Face in height more than half the length of the chelicerae, 

 sides slanting moderately outward from above downward. 



Anterior row of eyes shorter than the second, rather strongly pro- 

 curved. 



Chelicerce armed as usual. 



Epigynum relatively small, .8 or .9 mm. long; in form and structure 

 very similar to that of helluo, but the septum of guide broader and 

 more strongly expanded anteriorly, where it almost extends across the 

 entire depressed area.
