THE SOLDIERLESS TERMITES OF AFRICA 99 



legs, femora yellow-brown, tibiae pale yellow, tarsi yellow-white. Abdominal tergites and 

 dorsal stigmata pale yellow-brown, sternites and ventral stigmata still paler; cerci yellow. 



Posterior margin of head capsule evenly rounded; ocelli small, separated from compound 

 eyes by about two-thirds own least diameter; postclypeus moderately inflated, Pcl/\V, 026, 

 Pc1/Ra, 3-42-3-68, posterior margin somewhat undulating, median suture weak. Apical 

 teeth of mandibles short, La/Li, 0-41-0-53, Ra/Ri, 0-62-0-65; subsidiary marginal tooth of left 

 mandible separated from molar prominence by distinct notch in surface view, complex ratio 

 La/Li. L m , 7-50-8-75; apical and marginal teeth of right mandible in line, anterior edge of first 

 marginal longer than that of second. Pilosity of head capsule pale yellow-brown, uneven, 

 no pelt. Meso- and metanota less narrow at constriction M/W, 0-26-0-27. Fore tibia with 

 third apical spur only slightly smaller than other two.

Worker. Head capsule pale yellow, pilosity similarly coloured, fine, silky, inconspicuous 

 but fairly dense. Postclypeus weakly inflated, Pcl/W, 025, Pcl/Ri, 1-91; apical teeth of man- 

 dibles short, La/Lj, 0-54, Ra/Ri, 0-74, subsidiary marginal tooth of left mandible separated 

 from molar prominence by wide notch in surface view, complex ratio La/Li. L m , 12-45; first 

 marginal of right mandible slightly behind line of apical to second marginal, anterior edges of 

 marginal teeth approximately equal, Ra/Ri Rm. *5'9I- Fore tibia weakly inflated, Ti/T w , 

 4-47, third apical spur small but not vestigial, about one-third other two. Mesenteric junction 

 with proctodeum diagonal, to right of malpighian knot; enteric valve seating lateral in un- 

 opened abdomen, two outer lobes well developed, third lobe vestigial, connected to second 

 pouch of proctodeum by fairly long neck; membranous wall of valve beyond cushions with 

 sparse minute spicules.
