This species may be easily separated from those which have the 

 "frontal plate absent and anal i)ores present" by the characters assigned 

 in the diagnosis. 



The following is a complete description of type: 



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

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

 second antenna! joint; coxa longer than wide (4.5:3), unarmed; tooth 

 small. Cephalic plate sparsely pilose and punctate, the latter forming 

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

 thrice as wide as long; prebasal not exposed. Auteunce long, joints 

 long, penult, and antepenult, shortened. 



Dorsal plates distinctly bisulcate; anterior predorsal plates short, 

 posterior longest; ventral plates with an indistinct median depression. 

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

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