] 2o Mr. 0. J. With on Clieloiiethl 



Leg iv. : femur 2-0 (O'SIO) ; trochautiu 0-7-12 ; tibia 1-596 

 (0-42) ; tarsus 1-0G4 mm. 



? . Abdomen. — The genital area, which is covered by the 

 fourth pair of coxae, differs from that of the male. 



AntenncB (PI. VIII. figs. 3a-c).— Tlie fiagcllum (fig. 3 a) 

 is composed of four hairs, of which the three postesior 

 are simple and decreasing bacl<wards, while the anterior is 

 bifurcated and very much widened out in the middle, where 

 about five larger and smaller pointed teeth are found. The 

 scrruliform part of lamina interior with five dentated lobes 

 (fig. '6b,s). The moderately long galea (fig. 3c?) possesses 

 about three rather long terminal branches, as well as some 

 few distal, short, blunt teeth. The s.-rrula exterior is com- 

 posed of about 40 teeth. 



Palps (PI. IX. figs. 1 a-d). — The palps are much shorter 

 than those of the males. The inner margin of the tro- 

 chanter is gradually curved (fig. 1 b) ; the posterior and 

 superior tubercles are comparatively loAvcr than in the male. 

 The posterior and inferior tubercle is rather low and blunt, 

 while the superior is high and, in bearing a tooth-like 

 projection, resembles the lower of the two prominences in 

 the male. The femur, which is more than twice as long 

 as broad, has the inferior and superior outlines much less 

 convex than in the male. The upper and lower convexities 

 of the tibia (fig. 1 c) more even than in the male. The hand 

 is much broader than the tibia (1'35) and 1-4 times longer 

 than broad. 



Coxce (PI. VIII. fig. 3f/? ).— The fourth pair is scarcely 

 widened out distally and has the inner margin as long as the 

 liinder. 



Colour. — The colour is much lighter, especially on the 

 palps, which are light reddish ; the head is scarcely darker 

 than the thorax. The ventral surface, including the maxilhe, 

 is yellowish brown. There is great difference between the 

 specimens, as the darkest amongst them are scarcely lighter 

 than the males. 



Measurements. — Cephalothorax 2'0 (20) ; abdomen 3*0 

 (2'5) mm. 



Palps: trochanter 1-12 (0728) ; femur I'OG (O-Sl) ; tibia 

 1-932 (0-952) ; hand 1-87G (1*310), height 1-4G; fingers 

 1*35 mm. 



Leg i.: femur 1-4 (042), trochautiu O'GIG (0*504); 

 tibia 1-134 (0-308) ; tarsus 084 mm. 



Leg iv. : femur r97G (0-817), trocliantin 0-74; tibia 

 1-540 (0-364) ; tarsus 1*064 mm. 



Material— Mr. F. J. Jackson collected 8 ? and 13 cT 

 beneath the elytron of a beetle at Tavcita, Kilimanjaro.
