edges with several sharp tubercles, and separated by a deepish 

 groove from the rest of the cephalothorax. In this groove 

 are seated three oblong dark spots placed opposite the bases 

 of the three first pairs of legs. The front edge of the cepha- 

 lothorax is rather short and slightly excavated ; its lateral 

 angles project forwards between the bases of the fii'st pair of 

 legs and the falces, and there is a slight central projection, 

 immediately beneath which are seated two small prominent 

 teeth. The ocular eminence is of moderate size; the crests are 

 rather widely separated by a groove, and each furnished with six 

 or seven sharp teeth (fig. 1 a). In front of the eyes the cephalo- 

 thorax is elevated, the central part smooth, and marked by two 

 longitudinal dark parallel lines ; several sharp tubercles armed 

 with short black spines are arranged on each side of this smooth 

 space, and a few others are scattered on the sides of the cephalo- 

 thorax. The colour of the cephalothorax is yellowish-white, and 

 there are several large irregular brown marks on each side. The 

 eye-eminence is ferruginous. 



Tlie cephalothorax is separated from the abdomen by a groove, 

 between which and the eye-eminence is a transverse row of small 

 tubercles. The first two or three abdominal rings are distinctly 

 marked, and also crossed by transverse rows of minute but sharp 

 tubercles. 



A broad longitudinal dentated dark band extends from the 

 margin of the ring immediately behind the eye-eminence to the 

 apex of the abdomen. The edges of this band for a short di- 

 stance are straight ; they then curve alternately inwards and 

 outwards, forming two triangular projections on each side, the 

 posterior of which is smaller and often indistinct. The band is 

 often edged externally with white, and in many specimens is 

 altogether indistinct. The sides of the abdomen are irregularly 

 marked with brown. The whole under surface of the body is 

 white. 



The falces are strong; the basal joint is mottled above with 

 bro\\n, and furnished with a patch of small spines; the terminal 

 joint forms rather an acute angle at the point of curvature, and 

 is also furnished on its front surface with dark bristles. 



The palpi are rather short; the third joint is thickened at its 

 distal extremity, where it has a projecting angle on the inner 

 side ; they are marked with brown stripes on their upper surface. 



Tlie legs are long and slender ; the femora quadrangular, the 

 angles being armed Avith short dark spines ; the distal ends of 

 the femora are marked with a few brown spots ; both joints of 

 the tibise are also spotted with brown ; the extremities of the 

 tarsi are black. 



The jnale is smaller than the female, but has the cephalo-
