7 8 W. A. SANDS 



dorsal stigmata yellow-brown, sternites and ventral stigmata pale yellow-brown, sternites 

 yellow in middle; cerci yellow. 



Posterior margin of head capsule evenly rounded, ocelli medium-sized, separated from com- 

 pound eyes by slightly less than own least diameter; postclypeus rather weakly inflated, Pcl/W, 

 0-25, Pc1/Ra. 2-61, posterior margin undulating, not evenly rounded, median suture distinct. 

 Apical teeth of mandibles fairly short, La/Li, o-66, Ra/Pm, 086; subsidiary marginal tooth of 

 left mandible just clear of molar prominence in surface view, complex ratio Pa/Pi-Phi. io *55; 

 points of apical and marginal teeth of right mandible in line, anterior edges of marginal teeth 

 almost equal, first slightly longer. Pilosity of head capsule yellow-brown, uneven, no pelt. 

 Meso- and metanota somewhat wider at constriction, M/W, 0-32. Fore tibia with third apical 

 spur distinct.

Worker. Head capsule yellow-white, pilosity pale yellow, sparse and fine. Postclypeus 

 rather strongly inflated, Pcl/W, 0-33, Pcl/Ri, 3-05; apical teeth of mandibles rather long, Pa/Pi, 

 0-79, Ra/Ri, 1-07; subsidiary marginal tooth of left mandible just clear of molar prominence 

 in surface view, complex ratio Pa/Pi-Poi. 15*81; first marginal tooth of right mandible slightly 

 behind line of apical to second marginal, anterior edges of marginal teeth about equal, Ra/RiRiti. 

 21-01. Fore tibia scarcely inflated, Pi/P w , 4-55, third apical spur vestigial, almost obsolete. 

 Mesenteric junction with proctodeum almost transverse slightly slanted, to right of malpighian 

 knot; enteric valve seating lateral or slightly ventrolateral in unopened abdomen, rather 

 prominently two-lobed, connected to second pouch of proctodeum by long neck, membranous 

 wall of valve beyond cushions without detectable spicules.
