This .species may be easily separated from those which have the 

 "frontal plate ab.sent and anal pores present" by the characters assigned 

 in the diagnosis. 



The following is a com])l('te description of type: 



Keddish orange, head darkest, rather robust, widest before, moder- 

 ately smooth, sparsely pilose. Prehensorial legs reaching to base of 

 second autennal Joint: coxa longer than wide (4.5:3), unarmed; tooth 

 small. Cephalic plate sparsely pilose and punctatCvthe latter forming 

 two sulcations, h)nger than wide (7:5); basal plate partly concealed, 

 thrice as wide as long; prebasal not exposed. Antenna' long, joints 

 long, penult, and antepenult, shortened. 



Dorsal plates distinctly bisulcate; anterior i)redorsal plates short, 

 posterior longest; ventral plates with an indistinct nu'dian depression. 

 Spiracles round, anterior large, median and posterior small. First pair 

 of legs short, anterior and iiosterior subequal, former stouter. 



Coxa of anal legs strongly swollen, pores rather large, over 30 j last 

 ventral plate moderately wide (1.5: 2), sides converging.
