Chelicerce massive; margins of furrow armed as usual. Labium a 

 little longer than wide (16 :15); basal excavation as usual; attenu- 

 ated anteriorly, the sides below well rounded convexly, straight above; 

 front margin incurved or concave for its entire length. Legs strong, 

 moderately slender distally; tibia + patella IV evidently shorter than 

 the cephalothorax, the metatarsus a little longer than or nearly of the

 and II scopulate beneath, tarsi III and IV as usual ; spines of anterior 

 tibiae as usual; patella II armed anteriorly. 



Side ridges and furrows of the epigynum are of the usual form; the 

 guide is of the inversely T-shaped form, the septal piece is enlarged or 

 widened at its middle, being thus more or less fusiform, being narrow 

 adjacent to the transverse arms; transverse piece as long as or a little 

 longer than the median, its arms passing well out laterally behind the 

 lateral tubercles and being scarcely confined at the ends ; guide plates 

 along front of tran verse arms narrow, even more so upon posterior end 

 of septum where they fade out (PI. XVIII, fig. 4).
