By William Morton Wheeler 
Biological Laboratories, Harvard University 
The following species and subspecies are selected for de- 
scription on account of their unusual interest from sev- 
eral rich collections of Philippine ants received from Dr. 
J. W. Chapman, Dr. F. X. Williams, Dr. R. C. McGregor 
and others. 
Metapone gracilis sp. nov. 
Female. Length 7 mm. 
Head suboblong, about two-fifths longer than broad, 
slightly broader in front than behind, with feebly concave 
sides and somewhat sinuate posterior border. Eyes large, 
rather flat, about one and one-half times as long as their 
distance from the anterior corners of the head. Anterior 
ocellus distinctly larger than those of the posterior pair. 
Mandibles convex, with oblique, coarsely and bluntly 5- 
toothed apical and straight external borders. Median por- 
tion of clypeus trapezoidal, flat, sloping, slightly narrowed 
in front, with straight sides, posterior suture slightly ar- 
cuate, not impressed, anterior border only slightly project- 
ing in the middle where it terminates in a pair of broad, 
blunt teeth. Frontal carinse subparallel behind, their an- 
terior lobes obtusely angular. Frontal groove distinct. An- 
tennal scapes flattened, nearly four times as long as broad ; 
club of funiculi large, flat, much longer than the remaining 
joints together, the terminal joint longer than broad, as 
long as the combined two preceding joints; joints 2-7 much 
broader than long but gradually increasing in length dis- 
tally. Thorax slender, nearly four times as long as broad, 
subhexagonal from above, widest at its middle where the 
wings are inserted. Pronotum nearly as long as broad, 
with straight, anteriorly converging, scarcely submarginate 
sides. Mesonotum somewhat broader than long, flattened 
above, with arcuate promesonotal suture. Scutellum semi- 
circular, flat. Epinotum longer than broad, in profile sharply
