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 Colohopsis, many- 

 species of Camponotus s. str. and the Bornean ApJiomomyrmex hewitti 

 Wheeler. 



jyvymomyrmex claripennis, sp. nov. 



Female, Length 6 mm. 



Differing from the preceding species in its smaller size and in 

 having the clypeus 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 epinotum somewhat flatter and more sloping and the wings color- 

 less, 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 

 of 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 tibiae, tarsi and funiculi dark brown. 



Described from a single specimen (X 20) in the Klebs Coll. 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.
