68 W. A. SANDS 



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

 compound eyes by less than two-fifths own least diameter; postclypeus moderately inflated, 

 Pcl/W, 0-30-0-31, Pc1/Ra, 2-90, posterior margin evenly rounded, median suture present but 

 not strong. Apical teeth of mandibles rather long, L A /Li, 0-69-079, R A /Ri, 0-85-0-89; sub- 

 sidiary marginal tooth of left mandible separated from molar prominence by distinct notch 

 in surface view, complex ratio L A /Li.L m , 11-00-12-60; point of right first marginal tooth slightly 

 behind line from apical to second marginal, but anterior edges of marginal teeth equal. Pilosity 

 of head capsule yellow-brown, dense and uneven, no pelt. Fore tibia with third apical spur only 

 slightly smaller than other two.

Worker. Head capsule and its pilosity yellow, the latter very sparse. Postclypeus strongly 

 inflated, Pcl/W, 0-35, Pcl/Ri, 3-21; apical teeth of mandibles long, L A /Li, o-86, R A /R], i-oo; 

 subsidiary marginal tooth of left mandible separated from molar prominence by distinct notch 

 in surface view, complex ratio L A /Li.L m , 17-08; first marginal tooth of right mandible slightly 

 behind line of apical to second marginal, but anterior edge equal to that of second, R A /Ri.R m , 

 22-15. Fore tibia moderately inflated, Ti/T w , 3-88, third apical spur pale and about half length 

 of other two. Mesenteric junction with proctodeum diagonal, slightly sinuate, just to right 

 of malpighian knot; enteric valve seating very weakly two-lobed, almost a rim, connected to 

 second pouch of proctodeum by a definite neck, probably lateral in position in unopened 

 abdomen; membranous wall of valve beyond cushions with minute spicules.
