In spite of the fact that the front-row of eyes is slightly recurved, the eyes 

 equidistant, and the median four as near as possible in a square, this species agrees 

 so closely in other respects with Begillus Cambr. that the genus should be extended 

 to cover this. There is no question of any disappearance of the spinnerets — they are 

 quite normal, but lie flat. 



In addition, there is a small male Steplianopis Cambr. with the femora of the front- 

 legs especially profusely bespined and tuberculated, but it is too mutilated to measure 

 and describe accurately.

The cephalothorax is red-brown, with scattered pale yellow-brown bristles and 

 recumbent hair. The mandibles black-brown, with reddish-brown hair and bright 

 red fringes ; fangs black-brown. The lip and maxillae are also black-brown with red

 bristles. Between the sternum proper and the coxae is a rather wide area of white 

 tissue. The coxse and legs are dark brown, with yellowish-white hair and a patch of 

 white hair in the middle on the underside of the tibiae, brown spines, and grey claw-
