Comparisons. — These specimens agree so closely with Keyser- 

 liug's description that I have no hesitation in regarding McCook's. 

 tif/rina and Emerton's vulpina as synonyms of inhonesta. My 

 specimens do not agree with Keyserling's description exactly in the 

 form of the epigynum, but that organ shows considerable variation ; 

 Keyserling also states the length of the cephalothorax to be only 

 8.7 mm., and does not describe any light median thoracal band. 

 But he adds: " In meiner Sammlung besitze ich mehrere Exem- 

 plare, flie angeblich aus Brasilien stammen, ober vollstiindig mit 

 dieser Art iibereinstimmen, sie sind nur betrachtlich gi'osser und 

 haben eiu ganz schmales Mittelband iiber den vorderen Theil des 

 Cephalothorax, das von hellen Hiirchen gebildet wird und bis zur 

 zweiteu Augenreihe reicht." 



This species is similar in general appearance to L. carolinensis, 

 its dark individuals particularly so, but they may be readily dis- 

 tinguished by the relative sizes of the eyes of the first row.

(Numerous specimens from Chester county, Lancaster county, 

 York county, Pa. ; Pt. Pleasant, N. J. ) 



Exjes. — First row nearly as broad as the second, straight or the 

 lateral eyes slightly higher, middle eyes decidedly larger. Eyes 

 of the second row largest, fully their diameter apart. Third row 

 broadest, its eyes farther from each other than from the second 

 row. Dorsal eye area about one-sixth the length of the cephalo- 

 thorax. 



Form. — Cephalothorax in front not quite one-half its greatest 

 transverse diameter, highest at posterior eyes. Head oblifjue on 

 the sides. Length of chelicera about 1^ times the height of tJie 

 head in front. Sternum longer than broad. Legs stout, well 

 clothed with short hairs.
