On new and little-known Species of Ants. 87 
Anal scutum strongly narrowed caudad, caudally convex, 
with a median incision leaving a rounded lobe on each side, 
just cephalad of which on each lateral margin are two large 
setigerous tubercles. Anal valves with mesal borders 
strongly elevated and margined. The anal scale is caudally 
acute, on each side of the caudal apex a long stout subcylin- 
drical tubercle exceeding the tip of the median region. 
The telopodites of the gonopods of the type are broken 
off and lost. 
Length about 70 mm. ; width 11°6 mm.

Subfamily I. Powzrrva, Lep. 
Myrmecia rufonigra, sp. n. 
% major. Length (without mandibles) 11 mm. ; length of 
mandibles 2°0 mm, 
Black ; mandibles dark red-brown, apical two or three 
joints of funiculus dark red, the rest of antenne, the legs, 
mesonotuin, epinotum, and petiole red. ‘Che mesonotum has 
a dark patch on each side and the postpetiole has a dark band 
round its base, projecting on the upper surface into a conical 
patch extending nearly halfway across the node. 
Antenne without hairs, legs with abundant fine exserted 
hairs ; the whole of body with similar grey pilosity, which is 
longer on the clypeus and mandibles. Gaster, second node, 
and legs with a fine grey pubescence. 
Mandibles as long as head, with four large teeth besides 
the apical tooth, and smaller teeth between. External border 
feebly concave. Head slightly broader than long, narrower 
at occipital border, which is straight, not so broad in front 
proportionately as in pilosula; clypeus widely emarginate. 
Second joint of funiculus nearly twice as long as the first, the 
remaining joints decreasing gradually till the apical. ‘The 
scapes do not quite reach the occipital border. Shoulders 
of pronotum evenly rounded ; meso-epinotal suture distinct ; 
epinotum presenting an even curve, barely showing a base 
and a declivity. First node from above nearly circular, the
