Plate 23, fig. 2-6. 



Carapace with integument from light brown to darker, nearly 

 chocolate-brown; the lateral margins black with a pale supramarginal, 

 stripe on each side; eye-region blackish; a pale median longitudinal 

 line extending from the eye-area caudad and on each side of this a 

 pale or whitish line converging toward the corresponding one of the 

 opposite side with which it unites caudad of the stria. Sternum dark 

 brown to blackish, paler about margin and with a pale median longi- 

 tudinal mark in the anterior portion. Labium dusky, paler across 

 the distal end. Endites lighter brown. Chelicerae dark brown to 

 somewhat mahogany color. Legs dilute testaceous to dark brown or 

 dusky brown. Abdomen above almost black, the ^ blackish area lim- 

 ited on each side by a clear white line from which, beginning near 

 middle, a series of very short lines are given off on the inner side and 

 extend a little cephalad of mesad ; sides and \'enter paler, from dusky 

 testaceous to nearly black; the venter showing a vague pale longitudi- 

 nal line on each side. The light lines of carapace and abdomen 

 clothed densely with white hairs, the margin of carapace also clothed 

 with white hair, the hair of other parts dark. 



Carapace with dorsal line in profile nearly horizontal, a little de- 

 pressed at the groove; pars cephalica anteriorly very narrow. 



Anterior row of eyes strongly procurved, much longer than the 

 second row (posterior medians) but shorter than the third (posterior 

 laterals); median eyes much smaller than the laterals (diameters 

 nearly as 2:3), about their radius apart and about half as far from the 

 laterals; lateral eyes not fully their radius from the lower edge of 

 clypeus. Eyes of the second row but slightly larger than the anterior 

 lateral eyes, about their radius apart. Eyes of the third row clearly 

 smaller than those of the second, their diameters being as 4:5; each 

 its diameter from corresponding eye of the second row, a little more 

 than three times their diameter apart. Cephalothorax between six
