" ^ . 39 mm. Larger than the type of the species, and of a 

 darker colour, which is blackish or dark brown-black. Legs, antennae, 

 and mandibles brownish-yellow, the apical half of the flagellum darker. 

 The epinotal spines are much longer, at least as long as the space 

 between them. The meso-epinotal suture is feeble, forming no con- 

 striction. The pro-mesonotum forms a longer convexity and the 

 thorax is also longer (in the type of the species the pronotum only is 

 more abruptly convex). The pilosity is much scantier. Otherwise 

 almost identical with the type."

£ . 4-4*5 mm. Castaneous red or burnt sienna, the thorax a 

 little darker, the 1st node almost brown, legs paler and more yellowish. 

 Exserted pilose. hairs absent except on the clypeus. Head, thorax, 

 petiole, and abdomen evenly but not very densely clothed with flat, 

 almost scale-like, closely adpressed and silvery hairs, which lie some- 

 what transversely on the thorax. The hairs on the legs are also 

 silvery, but cylindrical and oblique. The antennae are finely pubes- 

 cent, the hairs simple. The silvery and flattened hairs on the body 

 sufficiently distinguish this species from all others in our region. 

 Head very finely and longitudinally striate, with a row of fine granules 

 between all the striae ; the cheeks, in front of the eyes, also slightly 

 rugose. Clypeus with a strong median carina, and several finer 

 lateral carihae or lines. Mandible closely striate. Thorax very finely 

 and closely rugulose ; the sculpture of the nodes similar but stronger, 

 almost granulate, especially the 1st node. Basal third of the abdomen 

 dull and finely aciculate, the rest smooth and shining. Head, thorax 

 and nodes dull.
