Affin ities. Closely allied to M. orhns, n. sp., M. quadratus, n. sp., 
M. tmideni Mjdb., and M. broomensis Mjiib., from all of which it is 
distinguished by differences in the frontal process, labrum, antennae 
and contour of the head. 
Biolorjy. The type series was collected from a dilajiidated 
tennitarium of Kutermes pasti'iuitor Hill from which the original

a colony of each of the following s]>ecies : M k<)termes sunte/n n. sj)., 
Rhinotermes sp., and Eutermes sp. The Stapleton series were found 
in the old tennitarium of Euterrnes palmersto^ii Hill described and 
illustrated in an earlier paper (P.L.S., N.S.W., xl, 1915, p. 93, 
pi. 17 and 18) in association with Coptoterm.es acinaeiformis (Frogg.)

ocelli and posterolateral angles of cly})eus. Fyes relatively large

wide as long (0-170 X 0-340), markedly convex, hemispherical
