New Ants from the Philippines 
47 
Mandibles and clypeus shining, feebly and microscopically 
reticulate, the former with a few coarse piiigerous punc- 
tures, remainder of head opaque, densely and finely punc- 
tate; thorax, petiole and appendages subopaque, sculptured 
likes the head but more superficially; meso- and metaplurse 
longitudinally rugulose; gaster smooth and shining. 
Hairs white, sparse, erect and obtuse, present only on 
the body; scapes and legs with fine, appressed, pale pube- 
scence. 
Head and thorax dark reddish brown; gula, occiput and 
epinotum darker and more blackish ; mandibles, scapes, me- 
sonotum, trochanters, tips of femora and tips and bases of 
tibiae yellowish brown ; funiculi fuscous ; tarsi yellow, with 
the last joint brown; gaster black. 
Two specimens taken by Dr. J. W. Chapman, one at Bag- 
uio, Luzon Island (type locality) and one Dumaguete, Ne- 
gros Oriental, Phillippines. The second specimen seems to 
be somewhat immature. I have attached this form to 
aurea, recently (1932) described by Karawajew from Ban- 
tam, at the western end of Java, because it seems to differ 
only in the decidedly thinner petiolar scale, different sculp- 
ture of the head and much darker coloration. Aurea was the 
first species of Acantholepis to be described from Indonesia, 
all the other known species of this rather large genus being 
confined to the Eurasian and African continents, except 
the Indian A. rothneyi wabsoni Forel which occurs in For- 
mosa. There is among my Philippine material, however, 
yet another species which is here described.

Head suborbicular, convex and rounded behind, including 
the mandibles slightly longer than broad. Eyes large, con- 
vex, somewhat behind the middle of the sides; ocelli large 
and widely separated. Mandibles moderately convex, 5- 
toothed, the first and fourth tooth from the apex larger than 
the others. Maxillary palpi very long. Clypeus large,

ing anterior border. Frontal area transversely triangular ; 
frontal groove distinct. Antennas slender; scapes extend-
