Dorsal scutum nearly rectangular; laterally, beyond the ist 

 transverse groove, very little rounded, with five distinct transverse 

 grooves ; its surface and also that of the free dorsal segments of 

 the abdomen not roughened, but deeply shagreened ; on each of 

 the ist — 3rd areas of the abdominal scutum there are two and two 

 submedian distinct tubercles, which are nearly thorn-like on the 

 3rd area ; 4th and 5th area entirely unarmed. Under the anterior 

 margin of the cephalothorax there are projected five horizontal 

 teeth (one of them in the middle, the four others in pairs on either 

 lateral corner) ; the upper anterior margin of the cephalothorax 

 is, moreover, finely granulated all over and presents one erected 

 tooth in the middle. Ocular tubercle twice as far from the ist 

 transverse groove of the scutum as from the anterior margin of 

 the cephalothorax, transversely oval, low, only over either eye 

 scattered with a few blunt granules. Free ventral segments of 

 the abdomen deeply shagreened, also the ist-4th coxae, the first 

 of which however has one frontal and one median longitudinal row 

 of blunt tubercles, and the second coxa has only a median one. 

 Spiracula hidden under several bridge-teeth, which overarch 

 the groove between the 4th coxa and the ist free ventral seg- 

 ment. Mandibles small; the ist segment with a well-separated, 

 entirely smooth apical hump. Palps slender, crossed over one an- 

 other ; trochanter with two ventral tubercles ; femur forming an S, 

 compressed laterally, scattered dorsally with 4-5 small tubercles, 

 armed ventrally with a complete series of pointed teeth ; there is 

 an inner apical tooth in addition ; patella flattened ventrally with
