exserted pilosity sparse, the decumbent pubescence more abundant, the 

 scapes and tibiae with short and almost adjacent hairs. Mandibles 

 shining, longitudinally striate and very sparsely and coarsely punctured, 

 with several teeth. Clypeus and cheeks longitudinally rugose, the rest 

 of the head, the thorax and petiole sharply, closely and fairly finely 

 reticulate-punctate, the disc of the pronotum and the dorsum of the 

 epinotum with not coarse longitudinal rugae superimposed, the 

 declivity of the epinotum shining and very superficially reticulate. 

 The abdomen finely rugulose, and also with a few shallow punctures. 

 The head is rectangular, the corners rounded, very little wider than 

 long, anterior margin of clypeus fairly straight, not emarginate. 

 Frontal carinae well developed and of the usual length. The scape of 

 the 11- jointed anteuna extends back almost as far as the posterior 

 margin of the head; the 2nd joint of the flagellum is somewhat longer 

 than wide, the 3rd-5th as long as wide, or barely longer, the 6th and 

 following joints all longer than wide, the club distinctly 3-jointed. 

 The shining frontal sulcus is distinct. Eyes placed a little behind the 

 middle of the sides of the head. Posterior margin of the head 

 moderately arcuate. The pro- and mesonotum together, seen from 

 above, reversed trapezoidal, with strongly rounded shoulders, the 

 upper surface of both parts feebly convex ; pro-mesonotal suture 

 distinct ; mesonotum about as long as wide, not marginate at the 

 sides. The meso-epinotal suture deep ; the dorsum of the epinotum 

 horizontal and trapezoidal, shorter than wide behind, the spines 

 moderately long, straight, divergent and oblique. The 1st segment 

 of the petiole trapezoidal, shorter than wide in front, the anterior 

 margin moderately arcuate, the convexity directed forwards, the 

 widely rounded anterior corners ending before the middle of the 

 segment, the upper surface concave in front. The 2nd segment 

 with a sharp and fairly deep longitudinal groove.

" The nests are made of carton, of a brownish colour, and attached to 

 the branches of Erica and other low shrubs. The surface of the nests 

 (which measm-e about 10-13 cm. in diameter and 18 cm. long) is 

 rougher and more uneven than those of Peringueyi."

" <^ . 31-34 mm. A little smaller than the type of the species. 

 The epinotal spines much shorter, hardly half as long, barely longer 

 than a fourth of the interval between them. Pro-meson otum narrower,
