myrmex and Camponotus. The structure of the head and body show 
that it lived in the cavities of twigs, in oak-galls or in abandoned 
insect galleries in solid wood, like the species of Colobopsis, many 
species of Camponotus s. str. and the Bornean Aphomomyrmex hewitti 
Wheeler. 
Drymomyrmex claripennis, sp. nov. 
Female. Length 6 mm. 
Differing from the preceding species in its smaller size and in 
having the clypens and mandibles more depressed and less truncate in 
profile, joints 2 — 9 of the funiculi somewhat longer in proportion to 
their width, the scapes longer and reaching nearly to the posterior 
border of the head, the eyes proportionally larger and more convex, 
the epinotnm somewhat flatter and more sloping and the wings color- 
l.ess, with paler veins and stigma. The petiole is clearly visible and 
in profile is longer than high, with a very blunt, low node, which 
has a short and rather abrupt, slightly convex anterior, a straight, 
sloping posterior surface. The sculpture and pilosity resemble those 
o f D. fuscipennis, but the hairs are more slender and delicate, and 
more appressed on the legs. The color of the body, femora and scapes 
is black, that of the tibise, tarsi and funiculi dark brown. 
Described from a single specimen (X 20) in the Klebs Coli. This 
specimen has the gaster and much of one side of the head enveloped 
in a white film and the body is surrounded by a number of white 
bubbles and a few stellate oak hairs. 
I suspect that Mayr’s Plagiolepis singularis, which is described 
and figured from a single female specimen, may also belong to Drymo- 
myrmex, but it cannot be referred to either of the species here de- 
scribed, because joints 2 and 7 — 9 of its funiculi are longer than broad, 
the petiole has a transverse node which is much higher than in either 
of my species and of a very different shape in profile, the epinotum 
is much less depressed and the hairs are sparser.
