TEKMITES FROM THE AUSTRALIAN REGION. 
Mr. i^roggatt’s collection contains a very closely allied species, 
represented by a nest series of imagos, nymphs, and workers collected 
by him at Kikori, Papua. The imago differs from M. hiroi as 
identihed by the writer in having larger eyes (0-323 x 0'323) ; 
larger ocelli (length 0"102, as against 0’085) ; ocelli near to the eyes, 
i.e., less than their short diameter ; antennae lighter coloured ; 
wings somewhat lighter (more greyish), with different micrasters. 
Desneux’s description would apply equally well to this species, 
but until specimens have been compared with the types the species 
of which all castes are available for study is here regarded as the 
described form.

Imago. 
Colour. Head very dark brown, postclypeiis rather lighter, 
antecly])eus cream colour ; labrum yellow ochre ; thorax and 
abdomen lighter than head, but darker than postclypeus ; pleura, 
tarsi, antennae, and palpi mummy brown ; sternites of abdomen 
mummy brown, darkest laterally ; 6tli visible sternite of male 
long and very dark ; wings dark brown, lighter than in 47. hiroi. 
Head (Fig. 30). Densely setaceous, hairs of large and small 
size, postclypeus straight in front, convex behind, one-third as long 
as wide ; anteclypeus nearly as long as postclypeus, rounded in 
front. F^es comparatively large (0-289 diam.), very prominent, 
separated from the lower margin of head by a space equal to one- 
third the diameter. Ocelli small, broadly oval, well separated from 
the eyes. Fontanelle indistinct. Antennae (Fig. 31) 14-jointed ; 
the 3rd joint verv short and narrow, almost hyaline , 4th to 8th 
moniliform. increasing in size progressively. 
Thorax (Fig. 30).— Pronotiim nearly straight in front, antero- 
lateral angles rounded, sides sloping to the slightly sinuate posterior 
margin ; the whole surface moderately densely haired. Meso- and 
metanotum with posterior margin deepl} emarginate.
