AUSTRALIAN CERAPACHYINI. 251 



25. Phyracaces mullewanus sp. nov. 



Male. Length 5.4 mm. 



Head, including the eyes, much broader than long, with broadly 

 rounded posterior portion and short cheeks, truncated behind the 

 ocelli, with strongly marginate occipital border, the margination 

 extending forward on each side of the gula to the level of the middle 

 of the eyes. Eyes and ocelli large and prominent. Mandibles 

 triangular, acutely pointed, rather narrow, with oblique, finely and 

 evenly denticulate apical and concave external borders. Clypeus 

 short, with straight, entire anterior border. Frontal carinse rather 

 far apart, parallel in front, approximated behind, half as long as the 

 distance between the anterior clypeal border and the posterior ocelli. 

 Antennal scapes not reaching to the posterior orbits; all the funicular 

 joints, except the last, a little broader than long, last joint twice as 

 long as the preceding, pointed. Thorax robust, as broad through the 

 wing-insertions as the head through the eyes. Pronotum not very 

 convex; mesonotum convex above, hexagonal, narrower in front than 

 behind. Epinotum with distinct base and declivity, the former in 

 profile feebly convex, shorter than the vertical, concave declivity, 

 the latter strongly marginate above and on the sides. Petiole as 

 broad as long, cuboidal, its upper surface convex, the anterior margi- 

 nate above and on the sides. Postpetiole broader than the petiole, 

 broader than long, broader behind than in front, with convex dorsal 

 and lateral surfaces. First gastric segment of a similar shape but 

 broader. Pygidium and hypopygium with broadly rounded tips. 

 Cerci absent. Genital appendages retracted. Legs slender and 

 rather short; hind coxre without lamellate tips. Wings short, vena- 

 tion much as in rugidinodis, but veins of the distal portion of the 

 discal cell obsolete and the pterostigma smaller, though thick. 



Shining; mandibles coarsely punctate, their bases, the epinotum 

 and petiole subopaque, finely and densely punctate; base and sides 

 of epinotum and upper surface of petiole also rugulose. Head and 

 scutellum shagreened; surface of occipital region very uneven; 

 mesonotum with large, coarse, deep, scattered, piligerous foveolse; 

 postpetiole and first gastric segment with smaller and more numerous 

 foveolse; gaster shagreened. 



Hairs yellowish, sparse, erect, pointed, and coarse, moderately 

 long, shorter on the legs. Pubescence absent, except on the antennal 

 funiculi.
