[Plate I. figs. 1 and 2.] 



Buthus Emiiiii^ sp. n. (PI. I. fig. 2.) 



Colour. — Trunk ochraceo-fuscous ; keels of tergites and of 

 cephalothorax black ; the ocular tubercle and the antero-lateral 

 regions of the cephalothorax infuscate ; a fuscous patch on 

 each side of the tergites. Legs and palpi ochraceous beneath, 

 the upper surface of humerus and brachium and anterior sur- 

 face of the legs feebly infuscate ; tail ochraceous above, the 

 inferior keels irregularly blackened ; vesicle clear ochraceous, 

 aculeus black in its second half. 



Cephalothorax slightly wider than long, its anterior border 

 very lightly concave ; the anterior keels well developed, 

 marked by smooth and rounded granules which anteriorly 

 become lost amongst the similar though smaller granules 

 which adorn the antero-lateral parts of the cephalothorax ; 

 ocular tubercle deeply cleft, very finely granular, the sides of 

 it, which are continuous with the anterior keels, are granular 

 in front and behind, smooth in the middle ; sides of cephalo- 

 thorax beset with larger and smaller granules ; running 

 obliquely backwards and inwards from the direction of the 

 lateral eyes there are about three subparallel series of large 

 granules ; the posterior keels well developed, granular, short 

 and parallel, their anterior ends not connected with the very 

 feebly developed external median keels and separated by a 

 slight interval from the internal median keels, which are 

 strong and granular ; the areas defined by the anterior and by 

 the internal median and posterior keels beset with larger and 

 smaller granules. 



Tergites. — The first six furnished with threestrongly granular 

 keels, which in the posterior half of the body project somewhat 

 beyond the margin of the plate ; finely granular throughout 

 and furnished in addition between the keels and especially at 

 the sides with many coarse granules ; the seventh tergite fur- 

 nished like the preceding with fine and coarse granules ; the 

 lateral keels well developed, strongly granular, complete 

 behind, united in front ; the median prominence elongate, 

 granular, and subcarinate. 



Sternites mostly smooth, sparsely punctured and hairy; 

 the first finely granular antero-laterally \ the last more coarsely
