formula (3, 8), (2, 4), 1 (5, 6, 7). Legs (fig. 7) well 

 developed, but rather slender ; there is a single long 

 hair at the end of the tibia, on the underside, and a 

 similar one on the coxa ; cligitules to tarsi ordinary ; 

 those of the claw very long, dilated, and truncate at 

 the extremity. Eyes (fig. 4 a) retained after treatment 

 with potash, in the form of a minute truncated cone, 

 situate in a clear fusiform space between the marginal 

 plates. Stigmatic spines (fig. 12) from three to five 

 in number, the central one being much the longest, and 

 curved. Marginal spines (fig. 12 ) minute, chiefly 

 simple, but a few are divided at the tips (fig. 12 b). 

 Anal lobes (figs. 9, 11) very thin, flat, and angular; 

 apex with three or four minute hairs. On the ventral 

 surface is a strong, inwardly projecting, and highly 

 chitinised lever-like organ (figs. 10/; and 11^), which 

 has a broadly-dilated base attached to the outer portion 

 of the retractile tube which envelops the hairs of the 

 anal ring ; the latter is furnished with six long hairs 

 (figs. 10 a and 11 a), and just below the fold of the 

 retractile tube are two pairs of long tubercles, each 

 bearing a single long hair (fig. 1 r) ; and there is a 

 group of minute spinnerets just within the anal cleft 

 (fig. 10/). On either side of the anal ring above are 

 two very long hairs and several minute ones. 



Long, 3'50-4 mm.; wide, 2*50-3 mm. 



Young adult female dull reddish-brown or bright 

 chestnut-brown, frequently with a trace of dull 

 crimson. Younger forms (fig. 2) dusky orange- 

 yellow ; eyes black, shining. 



Larva dull reddish ; antennas of six joints, of which 

 the third and sixth are longest ; fourth and fifth equal, 

 about the same length as first and second. Rostral 

 filaments unexpanded, extending beyond tibia3 of 

 posterior legs, the latter rather short ; digitules to 

 tarsi ordinary. Anal setge rather shorter than is usual 

 in the genus. Margins with a few stout hairs. A 

 single blunt spine occurs at the margin of each of the 

 spiracular openings.
