2nd and 4th, 5tli slightly longer than 2nd, 6th and 7th of 

 about the same length as 5th, the 8th and following gradually 

 becoming longer and longer, joints 13 — 16 twice as long as broad, 

 top-joint rounded at tip; prothorax very broad, dark fuscous, 

 sides, a very fine median line and a little rounded spöt on 

 each side of the median line a little behind the anterior 

 margin lighter coloured, provided with very long hairs at 

 the margins; anterior margin slightly emarginate, 

 anterior angles broadly rounded, sides strongly 

 tapering to the base, sides and hind margin nearly 

 forming a half-circle, meso- and metathorax more 

 flattened, partly lighter coloured; wings broad and 

 rounded, the two stout nervures at the front- 

 margin joining at the tip, mediana running through 

 the upper part of the wing, sending out an un- 

 forked branch already near the middle, cubitus 

 with 6 — 8 very stout oblique nervures; in the hind- 

 wing mediana seems to run unbranched out to 

 the tip; cubitus sends out up to 10 oblique very 

 stout nervures, the whole venation, however, is 

 here as in most of the members of the family 

 Metatermitidce subject to great variations, legs mo- 

 derate, thighs fairly stout; abdomen broad, rounded, 

 with 9 broad dark fuscous chitinous dorsal plates; 

 cerci stout.

 Eutermes 1 Diöij length of fore wing 8,1 mm, breadth of 

 ocellaris fore wing 2,4 mm, length of hind wing 7,4 mm,

 A very characteristic species, allied to E. tumuli Frogg., 

 but much smaller in size and lighter coloured; it has a similar 

 prothorax in shape but much smaller in size; it has the 

 largest ocelli (0,i9 mm) of all Australian species; in general 

 it is much more lighter coloured than E. tumuli Frogg. 



Three winged specimens taken at light during the night 

 near Oscar Range in the Kimberley-district of Northwest- 

 Australia (^Vi).
