TRAP-DOOR SPIDERS. 295 



Nemesia suffusa, sp. n,, Plate XVII., fig. A, 

 p. 215. 



Immature female, length 1\ lines (15^ mm.). 



Although no example was quite adult, this species 

 may readily be distinguished from all others yet 

 known to me, by its more elongated form, parti- 

 cularly the cylindrico-ovate form of the abdomen. 



The cephalotliorax is oval, broadest towards its pos- 

 terior extremity, where it is rounded, the fore-margin 

 being truncated ; the caput is well rounded and convex, 

 and the thorax perhaps more so than in other species, so 

 that when looked at in profile there is a considerable 

 dip or hollow at tlie thoracic fovea ; this fovea forms 

 a slight curve. Except that the lateral margins are 

 rather broadly pale towards the hinder part (though 

 the pale portion is ill-defined), the whole of the cephalo- 

 thorax is of a uniform dull yellowish-brown colour ; 

 the extreme lateral margin is marked by a black line, 

 and in one or two examples there was an indistinct 

 yellowish central longitudinal line from the eyes to 

 the thoracic junction, having a single row of promi- 

 nent bristles upon it. The whole surface of the 

 cephalothorax is fairly clothed with dusky yellowish- 

 grey adpressed hairs : the ordinary grooves and in- 

 dentations are well marked. 



The 61/68 are on the usual eye eminence, which is 

 perhaps rather more elevated than ordinary, and its 

 summit black ; their position is ordinary. It may, 

 however, be noticed that the fore-centrals are placed 

 more forward than in most of the other known 

 species ; the fore-centrals are about equally separated 

 from each other, and from the fore-laterals nearest to 

 each respectively; they are also separated from the hind-
