in some other genera) on the lateral margins of the caput, which 

 is of a well rounded convex shape behind the eyes. The oyos 

 are in two nearly concentrically curved rows, of which the 

 anterior row is the shortest, and the convexity of the curves is 

 dirocted backwards ; they do not differ greatly in size, the fore- 

 laterals being the largest, and the fore-centrals the smallest. 



The legs are moderate in length, 4.1.2.3, strong, and furnished 

 with hairs, bristles, and spines. 



The falces are long, powerful, and very prominent, or gibbous, 

 at their base in front. 



The maxillfo are strong and rather of a curved form, broadest 

 towards their extremity, where they are rounded on the outer, 

 and obliquely truncated on the inner sides. The labium is 

 oblong-oval, truncated at the apex, and about two-thirds of the 

 length of the maxilla). 



One species only is as yet known in Great Britain, and that 

 one has very lately occurred in Dorsetshire.

Length of the male 5 to 5£ lines: female rather larger. 

 Cephalo-thorax dark reddish-brown, darkest on the caput. 

 The legs are of a rather redder hue than the cephalo- 

 thorax. The palpi (of the male) have the cubital and radial 

 joints short; on the outside of the cubital joint is a large 

 prominent apophysis with two angular prominences on its upper 

 side. At the outer side of the radial joint is a pointed, and in 

 front of it a shorter obtuse, apophysis. 



The palpal organs are prominent and complex, with a curved, 

 finely pointed spine on the inner side. The falces are strong, 

 very prominent at the base in front, and like the caput in colour. 



The abdomen is oval, rather broadest behind, yellowish-brown, 

 marked, and spotted with black ; and has a longitudinal, central, 

 black band, tapering to a line at the spinners. On each side of
