Leptogenys insularis, Smith, Proc. Linn. Soc. XIV. p. 675. 
Smith only describes the worker of this species. The 
male (the female I have not seen) is black, the 
antennse on lower side of scape incline more or 
less to fuscous, the spurs and trophi pale testa- 
ceous ; tips of mandibles fuscous ; apex of abdomen 
(broadly) and antennge rufo-testaceous ; anterior 
tarsi inclining to testaceous at apex. Head and 
thorax opaque, alutaceous, covered with a fine close 
ashy, pile; apex of abdomen with long pale hairs. 
Head narrower than thorax, clypeus almost trans- 
verse at apex ; eyes reaching a little below the base 
of antennae and not far from the base of the man- 
dibles ; ocelli prominent ; there is a fine /^-shaped 
furrow over the antennae. Antennae with a short 
pedicle at the base, 13-jointed, microscopically pilose ; 
the basal joint three times as long as the 2nd- — a 
little longer than the basal joint of the flagellum, 
which is shorter than the 2nd; the other joints 
longer, the last is longer than the 12th; a fine 
keel runs down the centre of the mesonotum, the 
sutures dividing the front lobe shallow; sides of 
scutellum behind shining, obliquely striated; the 
apical half of the metanotum with several stout 
transverse keels. Abdomen opaque, finely alutaceous, 
longer than the head and thorax united. First 
segment shorter than the 2nd; its suture at base 
smooth and shining, the apex striated ; the tooth on 
lower side short, thick, slightly curved — the node as 
in worker — wings hyaline, the apex in front of 
stigma smoky; nervures testaceous, stigma fuscous.
