are erect, and are mainly confined to the margins of the frontal carinae 

 and the legs (the shape of these and of the spatulate hairs is the 

 same- as in Strumigenys, see Plate VIII, figs. 114nr, 117a and b). Head 

 fairly closely and longitudinally rugose on the anterior half, becoming 

 more reticulate-rugose on the posterior half, the spaces between the 

 rugae finely reticulate, the scrobes very shallowly and very finely 

 reticulate, almost smooth. Pro-mesonotum coarsely rugoso-reticulate, 

 the spaces between more finely reticulate or rugulose. Epinotum, 

 sides Of thorax, and nodes finely and closely reticulate-punctate. 

 Abdomen alutaceous, faintly shining, the rest of the body dull. 



Head trapezoidal, considerably narrowed in front, the posterior 

 angles widely rounded, the posterior margin straight or slightlv 

 convex. Frontal carinae widely divergent, dilated horizontally 

 outwards, extending back as far as the posterior fourth of the head, 

 where they curve downwards and then continue forwards as a fine 

 line, forming the upper and lower margins respectively of deep and 

 wide scrobes, which receive the whole of the folded scape and 

 flagellum. The clypeus is narrow and projects forwards, its upper 

 surface is depressed, slanting downwards, feebly carinate in the 

 middle. The corners of the anterior margin of the upper surface are 

 produced into sharp teeth, the space between the teeth strongly con- 

 cave. Below the teeth, the front of the clypeus is vertical or --even 

 inclined slightly inwards, convex transversely. The teeth of the 

 clypeus, seen from above, project well beyond the middle of the closed 

 mandibles. The latter closely striate, sparsely punctured, armed with 

 two sharp apical teeth, the rest of the masticatory margin merely 

 denticulate. Frontal area triangular and shining. Eyes composed 

 of about 10 or 12 facets, placed behind the middle of the sides and 

 below the scrobe. . Scape widened and flattened over the apical two- 

 thirds ; 2nd-8th joints of the flagellum very short, at least three times 

 wider than long, the club acuminate, four-fifths longer than the rest 

 of the flagellum. Pro-mesonotum wide, narrowed behind, as wide in 

 front as it is long ; pronotal shoulders narrowly rounded, prominent ; 

 posterior margin of mesonotum furnished with a small tooth on each 

 side (these are not easily seen, being partly obscured by the spatulate 

 hairs). Dorsum of epinotum nearly flat, quadrate, as wide as long, 

 very oblique, armed with two small, pointed, and triangular teeth. 

 The declivity a little shorter than the dorsum, fairly steep, marginate 

 at the sides, with an episternal lobe on each side below. The 

 peduncle of the petiole is as long as the node. The latter two-thirds 

 wider than long, rounded above, the anterior and posterior faces 

 vertical, the posterior face feebly convex transversely and concave
