134 Psyche [August 
Dark brown or black; mandibles, cheeks and clypeus deep red; articula- 
tions of legs and thorax, antennal funiculi and tarsi more yellowish. 
Worker media. Length 2.8 mm. 
Closely resembling the worker maxima, but the head is somewhat smaller 
and distinctly narrowed anteriorly, and the clypeus and cheeks are less 
deeply punctate and striate and therefore more shining. Ocelli absent. 
Antennal scapes reaching about half way between the eyes and the pos- 
terior corners of the head. Tooth on the external border of the mandibles 
obsolescent. 
Worker minima. Length 2 mm. 
Resembling the worker media, but the head is smaller, only a little longer 
than broad, as broad in front as behind, with feebly rounded sides, straight 
posterior border and rounded posterior corners. Ocelli absent. Clypeus 
convex and shining, its sides and the cheeks scarcely striate. Mandibles 
small, without a tooth on their external borders. Joints 2-6 of the antennal 
funiculi a little broader than long; scapes reaching half way between the 
eyes and the posterior corners of the head. Thorax not constricted in the 
mesoépinotal region above. Gaster as large as the head. Mandibles, 
clypeus, antennz and petiole yellowish like the articulations of the legs and 
thorax. 
Female. Length 6-7 mm. 
Body long and narrow. Head like that of the worker maxima but larger 
and with much larger eyes and well-developed ocelli. Clypeus very flat. 
Antenne 8-jointed; scapes reaching about one-third the distance from the 
eyes to the posterior corners of the head. Second funicular joint as long 
as the first, which is fully twice as long as broad; joints 3-6 subequal, fully 
as long as broad and not increasing in width distally, terminal joint shorter 
than the two preceding joints together. Thorax as broad as the head, but 
twice as long, from above regularly elongate-elliptical, dorsally depressed, 
evenly and feebly rounded. Sides of neck much swollen and projecting 
anteriorly. Mesonotum and scutellum each somewhat broader than long; 
epinotum very feebly rounded above, uniformly sloping, without distinct 
base and declivity. Petiole nearly as high as the epinotum, as long as high 
and broad, its node thick and cuboidal in profile, seen from above trans- 
versely elliptical. Gaster elongate elliptical, nearly as large as the thorax. 
Legs long and stout, with large claws and empodia. Wings moderately 
long (6 mm.) ; venation as in Plagiolepis. 
Sculpture and pilosity like those of the worker maxima. 
Black; mandibles (except the teeth), clypeus, antennz, tarsi, metanotum, 
anterior border of scutellum, articulations of the thorax, wings and legs, 
red; wings uniformly infuscated, with brown veins and blackish stigma. 
Described from two females, six maxima workers, one media and 
one minina, taken by Mr. John Hewitt at Bidi, Borneo, during 
August, 1907, “in the swollen internode of a shrub.”” This remark,
