oblique, subequal, except the third from the apex, which is 
distinctly smaller. Clypeus convex, bluntly subcarinate 
in the middle, its anterior border broadly rounded and en- 
tire. Pronotum from above elliptical, one and one-half 
times as long as broad, with evenly rounded sides, its 
dorsal outline in profile nearly straight and horizontal. 
Mesonotum as long as the pronotum, its subcylindrical 
anterior portion long, slightly concave laterally, dorsally 
and ventrally, descending to the posterior portion which 
embraces the sides of the epinotum. The projecting meta- 
notal spiracles interrupt the dorsal outline near its posterior 
end. Mesoepinotal constriction short and feeble. Epinotum 
broader than long, in profile with straight base and de- 
clivity, meeting at an obtuse angle. Petiole longer than 
broad, broader in front than behind, the node in profile per- 
pendicularly truncated anteriorly, rounded above, with its 
posterior surface gradually descending with even convexity 
to the posterior end of the segment. Legs very long and 
slender. 
Smooth and shining ; body, scapes and legs very delicately 
and indistinctly shagreened, with sparse piligerous punc- 
tures; mandibles less shining, very finely punctate-striate. 
Pilosity yellowish, bristly, of uneven length, erect and 
moderately abundant, long on the body, shorter and more 
oblique but coarse also on the scapes and legs. Pubescence 
undeveloped. 
Yellow, the legs and antennae scarcely paler; mandibles 
more reddish with black teeth. 
Described from a single specimen taken by Dr. J. W. 
Chapman, April 7, 1927, at Dumaguete Negros Oriental, 
Philippine Islands. This specimen, which superficially re- 
sembles an Anoplolepis longipes Jerdon, formed a portion 
of the prey captured by an army of 2Enictus Iseviceps F. 
Smith. The remainder of the prey comprised a worker of 
Ischnomyrmex longipes F. Smith, and two workers and 
several larvae of Polyrhachis (Myrma) mayri Roger. The 
head of the Chapmanella had been crushed and the tip of 
its gaster bitten off by its captors, so that the conforma- 
tion of these regions may be inaccurately represented in 
the figure. 
The genus Chapmanella appears to be most closely related
