Affinities. - The imago differ.s from M. sermtas (hh'ogg.) as fol- 
lows The wings are much larger anfl darker, the. i^ronotum notice- 
ably longer, the eyes much larger and more prominent, the ocelli 
larger, general colour lighter, postclypeus, legs and pleura distinctly 
paler. In colour it agrees more closely with M . yarrlceiis, hut the 
latter is a smaller specie.s, with much smaller eyes, ocelli and wings, 
and differently shaped pronotum. From .1/. leai it differs in its 
larger .size, much longer wings, longer pronotum, large.r i^yes and 
larger ocelli. Tlie soldier differs from J/. sermtas in its larger size, 
longer and more serrate mandibles, wider gula and longer jointed 
antennae. Tire latter organ does not reach the t\\> of the mandibles 
in the new species, whereas in Froggatt’s species it extends well 
beyond them. 
Biology . — Two complete ne.st -.series were taken on Melville Islanrl 
on 29.10.16 from small, rounderl, blacki.sh, woody termitaria (Fig. 
219) niea.suring about 11 hiches in height by 9 inches in diameter. 
In each ca.se about one-half of the .structure projectefj abme the 
surface of the ground and enveloped part of a small stump or root. 
Alate imagos and workers were plentiful, but soldiers were not 
numerous. Another community, comprising soldiers and workers 
onlv. was taken in Darwin (4.8.14) from “tubes" or covered-ways 
on a concrete pile 6 feet m height supporting a so-callcf! white-ant 
pu'oof " dwelling. Access to the floor-joists was gained by carrying 
the ■■ tubes " over the top of the pile and through a bolt-hoh; in the 
middle of the interposed metal plate. 4he common practice of 
fastening floor- joi.sts to the supporting piles by means of a bolt
