median pale annulus; metatarsi also with faint median annulus and 
metatarsi III] and IV with a more distinct light ring at distal end; 
tarsi III and IV with distal article pale and also with a submedian 
pale annulus. 
Carapace broadest at level of third sulcus from where the body 
narrows conspicuously caudad, the comparatively long abdomen 
being more abruptly narrowed or constricted at third segment with 
the anal scutum narrowly rounded; cephalad the cephalothorax is 
abruptly narrowed near level of third legs as usual and a little in- 
dented on each side caudad of anterior end. 
Carapace with the usual four sulci of which the first is bent back 
angularly at middle and the second is more moderately angulate in 
the opposite direction; the third sulcus is also weakly angulate and 
the fourth more strongly and acutely so between bases of the cones; 
a distinct median longitudinal sulcus between the first and the second 
sulci. Eye-tubercle distinctly limited, moderate in height, much 
wider than long; paired interocular processes close together, distinct, 
conically acuminate, pale in color. Tubercles along lateral sub- 
marginal elevated rims smaller and more obscure, these, as usual, be- 
coming larger but of only moderate size caudad, the tubercles widely 
separated, those across caudal border similar. A pair of widely sepa- 
rated tubercles between eye-tubercle and first sulcus. Area between 
sulci I and II with a few low tubercles; the second area with an 
irregular transverse row of more distinct setigerous tubercles and the 
tubercles of the last area more numerous as usual. Conical processes 
of carapace moderate in size, acutely acuminate with an acute curved 
branch on subdorsal side, (Plate 4, fig. 6,7). Anterior border of head 
elevated as usual, being limited caudad by a transverse furrow as in 
other species. Frontal margin not dentate. 
First three tergites of abdomen each with a transverse row of tuber- 
cles which decrease in size laterad and which are well separated. 
Anal tergite with a transverse row of four tubercles. Sternites of 
abdomen with corresponding rows of smaller tubercles. 
Coxae I distally bent rather strongly forwards, the second more 
moderately so, the third straight and a little shorter than the second; 
coxae I to IIT inclusive each with a row of distinct tubercles along the 
midventral line. Coxae IV of the usual general form; tuberculdte; 
the tubercles moderate, numerous but not dense; at distal end on 
mesal side with a proximally stout but not long process which distad 
is abruptly narrowed and terminates in an acicular point; on ectal 
side of distal end a shorter conical process.
