marginal tooth of left mandible with proximal end just clear of molar prominence in surface 

 view, complex ratio La/Li-L^,, i 1 •61-13-20; points of apical and marginal teeth of right mandible 

 in line, anterior edges of marginal teeth approximately equal. Pilosity of head capsule yellow, 

 slightly uneven, nearly a rough pelt with emergent setae. Fore tibia with third spur distinct.

Worker. Head capsule pale yellow, pilosity similarly coloured, very fine, silky and sparse. 

 Postclypeus rather weakly inflated, Pcl/W, 024, Pcl/Ri, 210. Apical teeth of mandibles rather 

 long, La/Lj, 0-69, 1<a/Ri. 0-97; subsidiary marginal tooth of left mandible just clear of molar 

 prominence in surface view, complex ratio La/Lj. L m , 14-45; first marginal tooth of right man- 

 dible slightly behind line of apical to second marginal, but anterior edge equal to that of second, 

 Ra/Ri Rm. 20-99. Fore tibia moderately inflated, Ti/T„, 3-86, third apical spur distinct. 

 Mesenteric junction with proctodeum diagonal, to right of malpighian knot; enteric valve 

 seating lateral in unopened abdomen, two lobes moderately developed, connected to second 

 pouch by proctodeum by long neck, membranous wall of valve beyond cushions with sparse 

 minute spicules.
