nearly to tlie apex of the second segment, and the longest of the latter extends to 

 the hase of the fifth segment. The fifth segment of the foretarsns bears three 

 ajiical ventral bristles, of which the middle one is long and the other two are short 

 and stout. On the mid- and hindtibiae these bristles are represented by only two 

 thinner ones, the posterior lateral bristle being absent. The measurements of the 

 mid- and hindtarsi are as follows : — 



Modified Segments.— The large eighth sternite bears about twenty-five bristles 

 on each side. The clasper (PI. XIII. fig. 4) has two free processes ; the one (f) is 

 finger-shaped, bearing some minute hairs at the edge, while the other (p) is short 

 and covered with very heavy bristles. One of these bristles is rather strongly bent. 

 The manubrium is slender and linear, being slightly bent downwards at the apex. 

 The ninth sternite (ix. st.) is somewhat razor-shaped, being truncate at the apex. 

 It bears a number of minute hairs, as shown in the figure. The spiral of the penis 

 forms two-thirds of a whorl only. At the apical edge of the ninth tergite (bearing 

 the sensory plate) there are laterally three bristles, two of which are long. 



Length : 2 mm. 



This species is easily recognised by the jirominent cone on which the apical 

 bristle of the seventh abdominal tergite is jjlaced, and by the sexual armature. 



We have one S example of this species from Saccostomus campestris, collected 

 by Mr. C. H. B. Grant at Umfolozi, Zululaud, on July 1st, 1904.

Head. — The frontal tubercle is very distinct. There is a row of three eye- 

 bristles and above them two additional bristles, besides some short hairs. The 

 occiput bears in or behind the middle two lateral bristles, one above the other, and 

 a snbapical series of hairs. This series is widely interrupted, the interspace between 

 the first and second bristles being twice the width of tlie interspace between the 

 second and third. The eye is ovate in shape. Tbe club of the antenna is three 

 times (c?) or twice (?) as long as it is broad. The rostrum reaches a little beyond 

 the apex of the forecoxa. The first segment of the labial palpus is longer than 

 the second, while the second, third and fourth are about equal iu length. The fifth 

 segment is longer than the third and fourth taken together. 



Thorax, — The pronotum is a little longer dorsally than the dorsal spines of 

 the comb. It bears one row of bristles and a comb of nineteen (c?) or twenty (?) 

 spines. The mesonotum boars two rows of bristles and on the back some additional 

 hairs, besides an irregular double row of small hairs at the base. There is also 

 a subapical series of four to six slender spines on each side. The mesothoracical 

 sternum bears four bristles laterally in the centre and some minute hairs near the 

 upper angle. The epimerum of the mctathorax bears six bristles (3. 2. 1). There 

 are two rows of bristles on the metanotum, besides two or three hairs on the 

 back in front of them. There is also one short apical spine on each side. 

 The episternum of the metathorax bears two bristles and a small hair, the latter 

 not being always ])rescnt, and the sternum has a single bristle. The bristles of the 

 njctathoracical epimerum are seven in number (3. 3. 1.).
