the inner side slightly convex in the proximal part, slightly concave 

 towards the extremity, behind somewhat widened from the base, 

 very slightly convex along the outer side, in ali almost equal in 

 width throughout and very little narrowing towards the extremity. 

 Tibia distinctly stalked, about as long and wide as feinnr, the outer 

 side rather strongly and very regularly convex, the inner surface 

 strongly convex. Hand a little longer than and ca. 1 '/« broader than 

 tibia, from rather regularly rounded base equally and strongly convex 

 on both sides, almost gradually running into the fìngers. These are 

 distinctly curvate, moderately strong, about as long as the hand or 

 very little shorter. 



Mandibles: galea very slender and short, with some fine teeth in 

 and near the extremity on the under side. 



Legs on the outer side with short and slightly davate hairs, on the 

 inner side with dentate hairs. Claws simple.

No eyes, ocular spots present. 



Cephalothorax, tergites and sternites of abdomen brown, palps red-

Cephalothorax: posterior hall nearly parallelsided, anterior half 

 roundly narrowing forwards, front margin rather straightened; cepha- 

 lothorax considerably longer than wide, strongly granulated, opaque ; 

 two strong transverse grooves, of which the anterior one is about in the 

 middle and slightly convex in the centrai part, the posterior one mudi 

 nearer to the hinder margin than to the anterior groove and rather 

 straight. The hairs short, davate, dispersed, yet there may be one or 

 two rather regular rows of 4 to 5 hairs along the front margin. 



Abdomen: the upper surface granulated, opaque, the last tergite 

 entire, the rest divided longitudinally by a fine line ; along the hinder 

 margin of the sclerites a row of short, b.ut strongly davate hairs; 

 there may also be a row of less numerous hairs before the hinder 

 row; no long hairs on the posterior somites. The lower surface of ab-
