 abdomen, 2'5 mm. long, 1*7 mm. broad. 



Cephalothorax oval, smooth, shining, furnished with a 

 few short hairs, and, when not rubbed, a profusion of white, 

 elliptical scales ; yellow, with dark markings, the latter 

 variable. Pars cephalica strongly arched, sides declivous, 

 obtuse in front, junction with thoracic segment faintly defined; 

 ocular area broader than long, hairy ; clypeus narrow, but 

 very deep. Pars thoracica broad, strongly arched, sides and 

 posterior area very steep, radial and lateral grooves faintly 

 defined; marginal hand broad, pale yellow, liyes black; in 

 three rows of 2, 2, 4 ; anterior pair widely removed, minute ; 

 second pair largest of the series, and separated from each other 

 by a space equal to fully twice their individual diameter ; the 

 four constituting the third row form a strongly procurved line, 

 and widel}^ removed from each other; each lateral eye of this 

 row is separated from its inner neighbour by three times its 

 individual diameter, and the two median eyes from each other 

 by a space equal to about two and a half diameters (fig. 18). 

 Legs moderately long, yellow, tajoering, hairy, armed with 

 long, fine spines, tarsal joints not scopulated. Relative 

 lengths, 1, 2 = 4, 3. Superior claws long, well curved, and
