each side. Sternum black, with a median longitudinal yellow stripe. 

 Legs testaceous to yellow, the femora with darker areas beneath; 

 tibiae annulate at ends on posterior pairs, those of first pair also 

 annulate at middle but annuli weaker. Endites and labium dark, 

 chestnut, distally paler. 



Abdomen broadly rounded in front, narrowing strongly caudad, 

 the end above spinnerets rounded. Clothed with short, pale, ap- 

 pressed hairs and longer, stout, brown setae arranged in transverse 

 series, each series on a transverse ridge, the ridges giving the abdo- 

 men the appearance of being annulate. Somewhat paler along mid- 

 dorsal region, with a narrow dark mark enclosed anteriorly, the 

 dorsum and sides elsewhere brown. Venter black between furrow and 

 spinnerets, a paler stripe each side. 



Anterior legs much stouter and longer than the posterior. Femora 

 of last three pairs of legs with numerous stout spines and some 

 smaller ones arranged in a close series along ventral surface, the 

 second femur also having a second series of finer, more widely sepa- 

 rated spines caudad of the first ones. The principal of these series 

 is represented on the first femur by four much smaller spines, one 

 at proximal end and three in line at the distal, while the caudal 

 series of femur II is represented on I by a series of similar small 

 spines. Tibia I strongly spined, there being a principal series of six 

 long, stout spines along the ventrocephalic surface; a series of four 

 somewhat smaller spines along the midventral line, one of these being 

 at the distal end and more widely separated from the others than 

 the latter are from each other; a series of four spines on caudal sur- 

 face, and a similar series on anterior face ; a series of three spines dor- 

 sally, and one of four spines along dorsocaudal line. Tibia II, which 

 is obviously shorter than I, is strongly curved and has along antero- 

 ventral edge a close-set series of numerous short but stout, moderately 

 curved spines, there being about seventeen spines in the series with 

 extra ones at intervals caudad of but close to the series; on anterior 

 surface at base and just above principal series five long and much 

 stouter spines, and on side above these but more widely separated, 

 two other stout spines; a series of three spines along anterodorsal 

 5dge and two very small, widely separated ones on dorsal surface, 

 one at distal end ; one small spine at distal end on anterior side.
