finer, erect and sparse on the alitrunk, nodes and gaster. 
A few hairs are slightly longer : on humeral angles, mesono- 
tum, and gastric dorsum, appearing flagellate, but the tips 
looped back on the shafts to suggest a false spatulate con- 
dition in the present specimen. 
Holotype a unique [USNM] taken in U. S. Plant Quaran- 
tine (No 686, 10385) at Honolulu from a fern plant origin- 
ating in the Philippine Islands. Closely related to godeffroyi, 
but differing in smaller size, pilosity and placement of the 
preapical tooth, among other characters. 
Strumigenys phytibia, new species 
Holotype worker: TL 2.5, HL 0.60, ML 0.29, WL 0.65; Cl 
69, mi 48. Closely resembles godeffroyi , with straight man- 
dibles and slightly recurved preapical tooth set less than its 
own length away from the dorsal apical tooth. Clypeus 
with anterior border only extremely feebly concave, almost 
straight. Posterior mesonotum gently concave. Propodeal 
teeth acute and elevated, but each is encumbered in a thin, 
areolate infradental lamella which becomes broadly convex 
below, the lamellae with a few barely perceptible strands 
of spongiform tissue on their lateral faces. Petiolar node 
subcircular seen from above, broadly rounded above and 
with steeply sloping anterior face as seen from the side. 
Postpetiolar disc convex, broader than long, its surface 
completely, distinctly and regularly longitudinally costu- 
late and opaque. 
Gaster with rather coarse basal costulae interspersed 
with fine parallel striation extending to about the mid- 
length of the first segment; remainder of gastric surface 
smooth and shining. Pronotum very indistinctly sub- 
striate over punctulation in a longitudinal direction, defi- 
nitely opaque. Head, alitrunk, legs and petiole densely 
punctulate, opaque; fore coxae and a ventral strip along 
mesopleura smooth and shining. 
Pilosity of alitrunk similar in plan to that of godeffroyi , 
but much reduced, the hairs smaller, fewer and more near- 
ly appressed. Humeral and mesonotal paired flagellate hairs 
extremely fine, as are also the lateral and posterior occipi-
