( 648 ) 



hinder part of the head bears a' snhapical series of five bristles on each side, and 

 between the second bristle and the antennal groove three more bristles, of which 

 the second is the longest. TLere are in addition a number of bristles on the back 

 and six short ones along the antennal groove. The bristles on the second segment 

 of the antenna are hardlv the length of the club. The maxillary palpns is shorter 

 than the rostrum, the latter not reaching to the apex of the anterior coxa. The 

 labial palpus consists of four segments, of which the last is the longest, being 

 nearly four times as long as broad. 



Thorax. — The prothorax bears two rows of five bristles on each side. The 

 comb consists of fifteen teeth. The mesonotnm and metanotnm are about eijual 

 in length, and bear each two rows of bristles. On the mesonotum there is on 

 each side a dorsal snbapical hair-like sjjine, and near the ventral angle a short 

 sjiine-like bristle. The metanotum and the first four abdnminal tergites bear on 

 each side two short stont apical spines, and the fifth tergite one s])ine. The epimerum 

 of the metathorax bears six bristles (3.3), the ventral one of the posterior row 

 being about twice the length of the other. 



Abdomen. —The abdominal tergites bear one row of bristles, the first tergite 

 having in addition one or two hairs in front of it. The number of bristles on the 

 middle segments is six or seven on each side. The stigma stands above the second 

 bristle on the middle segments. The seventh tergite bears one rather short apical 

 bristle, accomjianied on each side by a minute hair. The first abdominal sternite 

 bears one bristle, the second two, the next four sternites three on each side, the 

 sternite of the eighth segment, which sternite is large, a row of four or five bristles. 



Legs. — The bristles on the forecoxa are numerous and heavy, while those on 

 the mid- and hindcoxae are few in number. The hindcoxa bears a few hairs on the 

 innerside and two bristles posteriorly at the apex. The mid- and hindfemora 

 bear on the outerside a curved vertical row of four bristles, the upper one being 

 dorsal, the others ventral. There is one regular row of bristles on the outer 

 surface of the tibiae. The heavy bristles situated on the outerside of the dorsal edge 

 of the tibiae are all practically of the same length. There are eleven or twelve in 

 number. On the innerside of the dorsal edge there are three long bristles. The 

 bristles on the tarsi are numerous, but all short. The first hindtarsal segment is 

 one-third shorter than the hiudtibia. The filth tarsal segment bears four bristles 

 on each side, besides a snbapical hair, and is less than twice as long as broad. The 

 measurements of the tarsi are as follows : — 



Modified Segments.— The clasper (PI. XVI. fig. 90) is shorter than in C.granti. 

 It bears a stout bristle at the upper edge and another below the apex, besides some 

 slender hairs. The finger (f) is very small. The ninth sternite is elongate- 

 triangular, and bears a few hairs at the apex. The tenth tergite is devoid of hairs. 



Length, 2-2 mm. 



We have one S specimen of this species collected by Mr. (!. J. B. Grant, at 

 Deelfontein, Cape Colony, April 8th, 1002, from a species of Mus.
