88 THE ENTOMOLOGIST S RECORD. 
(3) Rhytidoponera (Chalcoponera) numeensis, Krn-André, subsp. 
borealis, subsp. nov. % | 
This ant agrees very well with André’s description of R. (C.) 
numeensis from New Caledonia, but differs in being smaller (4:0 mm. 
as against 5—5°5 mm.), and in the following characters :— 
Clypeus hardly, if at all, produced between the mandibles, its longitudinal 
rugae irregular, with faint reticulation between, this reticulation covering all the 
space between the coarse pits and rugae of the head, thorax and node. 
On the first segment of gaster the semicircular striae are almost lost in the 
dense and fine reticulation that covers this segment, which has in addition the 
fossae, some of them elongate, of numeensis. The second segment, as in nwmeensis, 
finely and semicircularly striate with scattered shallow fossae. 
The head is longer than wide, and widely emarginate behind ; the antennae 
extend a fifth of their Jength beyond the occipital border. 
Thorax widest in front, the inferior angles of pronotum with short teeth. 
Back of thorax regularly arched, descending to the declivity of the epinotum by a 
very obtuse angle. 
Node of petiole, viewed from above, wider than long, convex in front and 
nearly straight behind; viewed from the side, both edges are straight; under- 
neath the petiole is a flat process with a tooth at eachangle. Pilosity and colour 
as in nwmeensis. 
Stapleton, Northern Territory (G. F. Hill). No. 641. 
(4) Lthytidoponera (sens. str.) reticulatum, Forel. 
This species 1s very characteristic owing to the shape of the node. 
Workers were taken by G. F. Hill in the act of carrying off winged 
termites after a shower of rain. 
Darwin, Northern Territory, Oct. 16th, 1915. No. 672. 
(5) Rhytidoponera (Chalcoponera) metallica, Sm. & . 
Aug. 10th, 1914. Adelaide, Mt. Lofty Range. These 3s taken 
from Nest L. by Prof. Poulton, might be considered as a variety of the 
typical metallica. They are a uniform dark metallic green, and the 
coarse long striae on the front do not continue so far as in the typical 
form. ‘The scale also is straight, not concave behind, and the first 
seement of gaster has shallow punctures amongst the fine striation, 
and the second segment is similar, but the punctures are fewer and 
shallower. The anterior border of clypeus approaches more to a 
pointed form than in the typical metallica, and the head is not que 
so emarginate behind. 
(6) Lhytidoponera (C.) victoriae, Krn-André. 
Six 8s and two gs were taken by Prof. Poulton under a log 
(Nest M.), Aug. 15th, 1914, Victoria, in Healesville. 
The 3 of this species, which is not described, I hope to describe 
later. 
(7) Rhytidoponera (Chalcoponera) metallica, Sm. var. cristulata, 
Forel. g. (Hitherto undescribed). 
L. 7-5 mm. 
Black ; tarsi dark ferruginous, wings pale brown, nervures dark brown. 
Mandibles triangular, dentate. Clypeus swollen behind, the anterior border 
convex, with an impression running parallel with, and close to, the border. 
Antennal carinae short and divergent.
