 Described from a small colony, comprising two alate imagos, six s( Idiers,. 

 40 nymphae, about twenty larvae and two neoteinic queens, taken in a hollow 

 Eucalyptus stumj), in .lanuary. This appears to be a rare specie--^, known 

 hitlierto only in the alate form. It is recorded from New Zealand.

Head small, longer than wide, rounded behind, the whole surface minutely 

 shagreened and bearing scattered setae. Eyes very large (0.329 x 0.282) and 

 prominent, coarsely faceted, lower margin half the vertical diameter from lower 

 margin of head. Ocelli large, contiguous to inner margin of eye. Clypeus 

 rather less than half as long as wide, anterior margin concave, posterior margin 

 convex. Labrum rather large, markedly convex and swollen on the sides, rounded 

 in front. Left mandible witli a large, sharp tooth at the apex, followed by a 

 much smaller pointed oiu' and a short, wide, cutting edge; riglit mandible with 

 the two apical teeth as in left and a very much wider cutting edge towards tlie 

 inner side. Antennae (Fig. 35) long, 16- (rarely 17-) jointed, springing from 

 a circular cleft in front of the eye, 1st joint short, stout and slightly narrowed 

 at the apex, 2nd three-fourths as long and nearly as wide at apex as 1st, 3rd, 

 4th and 5th equal, or 3rd shorter and narrower than 4th and 5th or, rarely, 3rd

ir/jir/s (Fig. 36, PI. xxxvi.) ei|nal, ratlier less tluin four times as long as 

 wide; a few minute setae on costal margin as far iis junction of last branch of 

 radial sector, and a few on radius and radial sector; under high power the 

 principal veins have a scaly appearance. In the forewing the subccsta joins 

 the costa just beyond the cross suture; the radius also is short and joins the 

 costa a little hcfiprc tlie middle of tlie wing; the radial sector has seven or eight
