AND THE PHILIPPINES 
By William Morton Wheeler 1 
Chapmanella gen. nov. 
Worker: Integument rather thin, smooth and hairy. 
Head elongate, high in the frontal region, depressed and 
narrowed behind, without posterior corners. Eyes very 
small but distinct, placed well up on the dorsal surface 
near the middle of the sides. Ocelli absent. Mandibles 
narrow, decussating, with oblique, dentate apical borders. 
Clypeus rather large, not extending back between the 
frontal carinse, which are very short, poorly developed and 
not very far apart. Frontal area and groove absent. Palpi 
short, the labial pair 4-jointed, the maxillary pair appar- 
ently 6- jointed, with the terminal joint much shorter than 
either of the two subequal preceding joints. Antennse 
very long and slender, 12-jointed, inserted near the pos- 
terior corners of the clypeus; funiculus filiform, scarcely 
thickened apically. Antennal and clypeal fovese not con- 
fluent. Thorax long and slender, with distinct prome- 
sonotal and mesoepinotal sutures. Anterior portion of 
mesonotum narrow and subcylindrical ; mesosterna convex 
and somewhat swollen anteriorly. Metanotal spiracles 
prominent, closely approximated, on the dorsal surface just 
anterior to the base of the epinotum, which is small, 
short and unarmed, with its spiracles situated on each side 
at the angle between the base and declivity. Petiole small 
and elongate, with a low, erect node at its anterior end. 
Gaster moderately large, with short first segment, which is 
convex anteriorly but does not overlie the petiole. Legs
