Sternum wider than the intermediate coxae, often unequal. Anterior coxae 

 separated by the widtb of the lip at the base. 



Felices rather robust, vertical, never ridged . 



( ^ ) Maxillae wide at the extremity; their superior external angle present- 

 ing one or two conical pi ejections. 



{$) Palpus short; femur, robust, arrued below with a simple or bifid 

 apophysis; patella l<jug and a little convex; tibia shorter armed with 

 external apophyses, slender and slightly developed; tarsus narrow 

 and elongated, terminating in a point, projecting beyond tiie bulb. 



Legs 4, 1, 2, 3, or 4, 1, 3, 2, slightly unequal. Tibia and patella of the first 

 shorter than the cephalothorax; metatarsus more slender than tibia 

 and patella of the fourth. PatelU (a'one) of the third as long and 

 of ten a little more . obust than patella of the fourth; tibia of the 

 fourth almost {.arallel and cylindrical. Femoral, tibial, and meta- 

 tarsa] spines on the four pairs; no patellary spines.

Cephalothorax but slightly elevated; thoracic part not dilated, a little con- 

 tracted, about a third the longer; cephalic part plane, inclined, 

 limited by a very faint transvercc depression, cut by a longitudinal 

 stria . 



Eyes: those of the face very unequal, almost touching, forming a straight 

 line. Dorsal eyes scarcely smaller than the lateral, not prominent* 

 and not further apart. Quadrangle almost a third wider than long; 

 dorsal eyes further from each other than from the lateral borders. 

 clypeus very narrow, with hair. 



Sternum oval, wider than the intermediate thighs. Anterior thighs sep- 

 aparated by at least the width of the lip; th'ghs of the fourth 

 longer . 



Legs 4, 1, 3, 2; first pair much more robust, particularly the femur and the 

 tibia. Tibia of the first a little long3r than the patella; the two 

 articulations shorter than the cephalothorax; tarsus and metatarsus 

 more slender and almost as long as the two preceding articulations. 

 Tibia and patella of the third much shorter than the tibia and patella 

 of the fourth. Tibia of the fourth almost parallel; tarsus and meta- 

 tarsus of the fourth as long or almost as long as tibia and patella. 

 Femoral, tibial and metatarsal spines on the four pairs; two patellary 

 spines on the two posterior pairs.
