the tibipe and the apical third or fourth of the femora. The bUick 

 gaster has very pronounced metallic blue reflections. 



A single specimen obtained several years ago from Staudinger and 

 Bang-Haas. It is from New South Wales and was erroneously labelled 

 " L. rufipes Emery."

" Worker. Length 8-9 mm. 



"Mandibles a little shorter than in erythrocephalus, densely punc- 

 tate and shagreened, subopaque, their terminal borders armed with 

 19 to 20 very distinct, crowded teeth. Clypeus impressed in front 

 in the middle, straight behind its anterior border. Head as in the 

 typical erythrocephalus, with the sides convex behind the eyes, much 

 less narrowed than in rarians Emery and its varieties, about twice as 

 long as its anterior diameter. Eyes situated much further back than 

 in erythrocephalus, towards the third fifth of the head. Antennae a 

 little shorter than in erythrocephalus, form of thorax similar, but some- 

 what less elongate. Petiole with a strong convexity below. It is 

 more elongate behind the node, which is lower, not so thick, with its 

 posterior surface more oblique and an antero-superior surface which is 

 much shorter and a little more clearly marked off from a sub truncate 

 antero-inferior surface. The legs are shorter. 



" Deep blackish brown. Scapes, femora and petiole paler brown. 

 Funiculi, border of mandibles, tarsi, sometimes the tibiae, and in 

 general the posterior third of the epinotum, the coxae, bases of the 

 femora and the lower portion of the thorax with the lower portions 

 of its sides behind, testaceous. This color is almost the same as that 

 of varians var. rolhneyi Forel, but the latter has the head much nar- 

 rowed behind and the legs and antennae are much longer. 



"Male. Length 7.7 to 8 mm. 



"Mandibles elongate triangular, with obtuse tips. Scape shorter 

 than the three first funicular joints together. Head like that of the 

 worker, but narrower in front than behind the eyes. Pronotum form- 

 ing a narrow and flat neck in front, to which the anterior convexity of 

 the metanotum descends vertically; but the posterior raised third 

 of the dorsum of the pronotum forms the lower portion of this sub-
