Cephalothorax fiat, but little elevated, very much elongated, parallel, ob- 

 tusely truncated behind; a slight horizontal depression separating 

 the cephalic part. 



Eyes: The dorsal eyes situated a little beyond the middle of the cephalo- 

 thorax, scarcely projecting above, of the same size as the lateral, 

 and forming with them a group much longer than wide. Eyes of 

 th'^ face very unequal, touching, forming a straight line, surrounded 

 by fine circles of hairs. 



Clypeus very narrow; hairs forming ihe beard sparse. 



Sternum oval, more slender at the two extremities, wider in the middle 

 than the intermediate coxae, projecting between the anterior 

 coxae. 



Lip at least as wide as long, semi-circular, or in a very obtuse triangle. 



Maxillce extending much beyond the lips but nevertheless rather short and 

 very wide. Square at the extremity. 



Legs: Fourth legs the longest; the three anterior paii'S equal or almost 

 equal; the two posterior pairs unarmed; {$) metatarsi of the first 

 and second alone provided with some inferior spines; {$) tibiae and 

 metatarsi of the first and second presenting two rows of inferior 

 spines; tibia of the first robust, of the same length or scarcely 

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

 than patella and tibia of the fourth; metatarsus and tarsus of the 

 fourth shorter than patella and tibia. 



Falces (6 9) robust, short, vertical. 



Palpus ( $ ) not very robust; tibia very short, provided with an external 

 apophysis; tarsus obtuse oval; bulb simple, reaching at least the 

 superior third of the tarsus; ( ? ) rather slender; tarsus slightly en- 

 larged and cylindrical.

Cephalothorax about twice as long as wide, the posterior part plainly 

 narrowing a little, almost vertical towards the sides, rather low, 

 the cephalic part scarcely higher than the thoracic. 



Clypeus very low, less than ^ the diameter of the anterior middle eyes, 

 without thick hairs. 



Sternum much wider than the coxae, not projecting between the coxse of 

 the first pair. 



Eyes: Are a large, occupying almo5t half the length of the cephalothorax. 

 Quadrangle only a little wider than long, at least as wide in front as 

 behind. Anterior row of eyes rather strongly curved upward, mid- 

 dle eyes plainly visible when the cephalothorax is looked at from 

 above, touching, the lateral well separated from the middle, eyes 

 of the second row small, and a little further from the posterior eyes.
