proximad, external spines five in number (including distal one), internal 

 spines eleven in number, the distal one separated from the others by a 

 considerable interval ventrad of the femoral brushes; cephalic tibise 

 (exclusive of claw) equal to about three- fifths of the femoral length, 

 armed externally with ten spines, internally with ten to eleven spines ; 

 cephalic tarsi very long and slender, the length being more than one 

 and a half times the tibial length, metatarsi alone about three- 

 fourths the tibial length. Median limbs very short, femora being no 

 longer than the cephalic coxa?. Caudal limbs of medium length, 

 femora slightly inflated in proximal half; 7 tarsi equal to three-fifths 

 of the tibial length. 



General color clay-color, the dorsum of the pronotum and the 

 middle of the dorsum of head washed with drab and the cephalic 

 limbs largely gamboge-yellow. Face bistre ventrad ; from the antennal 

 bases extend ventrad a pair of parallel straw-yellow lines; antennas 

 of the same color; eyes obscurely barred with bistre. Tegmina and 

 wings very pale brownish hyaline. Cephalic coxse clear gamboge- 

 yellow; trochanter and femora lined ventro-laterad with bistre, finely 

 clotted with same dorsad; tibiae thickly sprinkled with bistre; all 

 spines tipped with dark brown. Median and caudal femora thickly 

 punctate with bistre which is arranged more or less in longitudinal 

 series.

Kikuyu Escarpment, Brit. East Africa. One male. 

 Apparently this is the only exact record of the occurrence of the 

 species in East Africa. 



7 This may indicate considerable saltatorial ability as found in the genus 

 Yersinia, which has similarly subinflated femora.
