midillf. There are two bristles posteriorly at the apex, the second being the shorter. 

 The forefemiir has one subapical ventral hair and three lateral ones on the ontcr- 

 side. On the hindfemur there are two ventral snbapical bristles on the outerside 

 and one lateral subapical bristle on the innerside. The tibiae have one row of 

 lateral bristles on the onterside and a number of ventral hairs, of which the 

 snbapical pair is heavy, but short. The fifth and sixth pairs of dorsal bristles of 

 the hindtibia are far apart, with a single short stout bristle in between. The longer 

 bristle of the fifth jiair is longer than the longest apical one, the latter not reaching 

 to the apex of the first hindtarsal segment. The longest a[)ical bristle of the second 

 hindtarsal segment reaches to the apex of the fourth segment. The fifth segment 

 bears four bristles on each side and a subapical hair. The sole of this segment is 

 hairy, and bears at the apex two short widely separated bristles. The measurements 

 of the tarsi are as follows : — 



Modified Segments.— The eighth tergite of the c? is large, with some long bristles 

 placed as shown in the figure (PI. XII. fig. 58, drawn from slide). The eighth 

 sternite is very small, curved, finger-like (PI. XII. fig. 58, viii. st.). The finger (f) 

 is straight, elongate-conical, with some hairs, of which one near the apex and another 

 above the middle are the longest. The manubrium (m) gradually narrows to the 

 apex, and is slightly curved. The ninth sternite (PI. XIII. fig. 65, ix. st.) is 

 mesially not divided (as far as can be made out from the slide). It is very peculiar 

 in structure, bearing three large scales (modified bristles) near the apex, of which 

 two are frayed out at the edges. The spiral of the penis consists of a (piarter of a 

 coil only. 



The eighth tergite of the ? is without hairs above the stigma. It bears one 

 long bristle below the stigma, and a number of hairs farther down, as shown in 

 PL XIII. fig. 59 (taken from the slide, the outline in eouseixuence not being 

 exact). The eighth sternite is small. The stylet is cylindrical, being about four 

 times as long as it is basally broad. The anal sternite bears some heavy spine-like 

 bristles beneath.

We have three examples of this species, 1 c? and ^i ? ? , from Deelfontein, Cape 

 Colony, March 19th, 1902, from Otomtjs (5/-a«<?, collected by Mr. C. J. B. Grant. 



28. Ceratophyllus octavii spec. nov. (PI. XIII. fig. 61). 



?. This species is closely allied to C. numae in having two genal spines. 



Head.— The head is much more strongly rounded than in that species. The 

 frons is not angulate, but bears just a trace of a notch about midway between 

 the maxillary palpi and the first pale spot. The two genal spines lie across each 

 other, the point of the second being visible in front of the first. 



Thorax.— Each of the thoracical and abdominal tergites bears one row of
