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 siihmedian 

 pale annulus. 



Carapace broadest at level of third sulcus from where the body 

 narrows conspicuously caudad, the comparati\ely long aljdomcn 

 being more abruptly narrowed or constricted at third segment with 

 the anal scutum narrowly rounded; cephalad the cephalothorax is 

 abruptl\' narrowed near \eve\ 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 l)uck 

 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 acimiinate, 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 wideh' sepa- 

 rated tubercles between eye-tuliercle 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 nvunerous 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 III inclusive each with a row of distinct tubercles along the 

 midventral line. Coxae IV of the usual general form; tuberculate; 

 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.
