little-known Species of Ants. 89 
Promesonotum arched, metanotum very prominent. Epi- 
notum feebly curved. Node from above long and narrow ; 
the anterior quarter is divided from the rest by a transverse 
rilge beyond which the node narrows and widens again to 
the base. In profile it is low, rising to its highest point 
behind, the projecting ends of the above-mentioned ridge 
forming a break at the anterior quarter. Gaster deeply con- 
stricted between the first and second segments. 
Mandibles finely striate. Clypeus and rest of head coarsely 
and irregularly longitudinally rugose. Promesonotum and 
metanotum with coarse, shining, reticulate punctures, which 
tend to become longitudinal in direction on the latter part of 
mesonotum and on the metanotum. Sides of thorax and the 
epinotum irregularly longitudinally rugose, the node slightly 
roughened, gaster smooth. Coxe and femora faintly 
reticulate,

%. Length 7°0 mm. 
Dark brown, shining ; mandibles, antennee, promesonotal 
suture, and declivity of epinotum castaneous brown ; legs 
similarly coloured, but brighter, almost red; borders of 
segments of easter and the apical segments castaneous brown ; 
petiole less deep brown than body. 
Body with a fine yellowish pilosity, thickest on gaster. 
Antenne and legs pilose. Four or five extremely long hairs 
on scape. 
Mandibles with four teeth, one on apex, another at extreme 
base, and two between, with indications of a few smaller 
irregular teeth in between. A groove runs from the upper 
surface of base and curves to the outer border, finishing at 
apex. Hyes large, in front of middle of sides of head. 
Clypeus has a high and sharp median carina ; the extreme 
apex of clypeus is truncate. 
Head as long as broad, broadest at base of mandibles, sides 
feebly convex, occipital border slightly concave. Scape 
passes the occipital border by a little more than its thickness. 
Second joint of funiculus longer than first, the joints thence 
diminishing until the apical. Thorax in profile slightly 
depressed at mesonotum. Base of epinotum nearly twice as
