little-known Species of Ants. OF 
Head and thorax as in 8 with sexual differences. Spines 
of epinotum and scale somewhat shorter and blunter, 
Dull, gaster shining. Sculpture somewhat coarser than in 
8%, assuming on the dorsum of thorax a tendency to run in a 
longitudinal direction. 
A few hairs on head, thorax, and gaster, asin 8. A thin 
grey pubescence on gaster. 
S (hitherto undescribed), Length 5°5 mm. 
Uniform dark castaneous brown; mandibles, clypeus, 
antennee, and legs yellow. 
Eyes very prominent, occupying one-half the sides of head. 
First joint of funiculus somewhat gibbous. Scale low, 
broad, and rounded in protile. Body with a fine superficial 
ground-sculpture. 
Daiwin, Northern Territory, Australia (Ail). 
Types in the British Museum. 
After comparison with a cotype, which the author kindly 
sent me, there is no doubt that the insect described by me in 
1915 as P. delivata is none other than H.nery’s species. 
Mr. Hill found a nest of these ants, which is made of a 
fragile carton between two leaves fastened together. The 
whole nest is not more than 4 inches square and about # inch 
in the deepest part. 
Polyrhachis (Campomyrma) micans, Mayr., race ops, Forel, 
var. rufa, nov. 
%. Differs from micans in colour, which is black, with the 
mandibles, clypeus, frontal area, anterior portion of frontal 
caringe, cheeks at base of mandibles, antenna, legs, scale, and 
easter light red. The upper portion of the declivity of 
epinotum below the teeth and the teeth themselves are red, 
but not so bright as the other red portions. 
Thorax formed like that of the race ops—i. e., narrower 
than in micans; the anterior border of clypeus not so deeply 
concave and the teeth not so prominent as in mdcans. ‘The 
teeth on epinotum much shorter and blunter than in micans, 
and the inner spines on the scale are somewhat shorter and 
more parallel, while the lateral spines are reduced to mere 
triangular teeth. 
This variety would appear to differ from the var. dentinasis 
recently described by Santschi by its red colour and the even 
greater diminution of the lateral spines of the scale.
