Forel, in the much shorter epinotal teeth, the finer rugosity of the 

 abdomen, and particularly in the general sculpture." 

 So far not recorded from our region.

$ . 3 - 8-5 mm. Black ; tibiae, tarsi, and scapes ferruginous, the 

 metatarsus of the middle and hind legs a little darker. Flagellum 

 piceous. Pilosity scanty, composed of regularly disposed and very 

 short, blunt, and thick whitish hairs, erect on the body, oblique on 

 the legs and scapes. Below each eye there are three longer and 

 thinner hairs of a brownish colour. Pubesence present only on the 

 club of the flagellum. The sculpture of the head consists of a close 

 network, the strands of which are somewhat flattened and accentuated 

 longitudinally (this is due to the longitudinal strands being con- 

 tinuous, whereas the transverse ones are short and broken) ; the floor 

 of the meshes is shallowly rugulose, and the meshes are rarely twice 

 as wide as the strands which bound them. In the type of the species, 

 on the other hand, the strands are sharper, less flattened, and the 

 meshes are quite three times or more wider than the strands, and 

 their floor is reticulate rather than rugulose. The thorax is longi- 

 tudinally rugose and partly reticulate, except in front, where it is 

 transversely and irregularly rugose. The sculpture of the thorax in 

 front and behind is very strong, forming sharp outstanding ridges, 

 and between the epinotal spines there are three or four equally strong 

 transverse rugae. Sides of the thorax reticulate-punctate and sparsely 

 sulcate. Declivity of the epinotum smooth. Both nodes are very 

 coarsely and more or less longitudinally rugose above, deeply sulcate 

 between the rugae. Legs and abdomen very closely, finely, and 

 evenly reticulate-punctate (appearing granulate under a low power). 

 The basal third of the abdomen is also longitudinally and moderately 

 rugose, the rugae diminishing apically. Tibiae and femora also partly 

 rugose. 



Head a trifle wider behind than long, narrowed slightly and 

 gradually in front of the eyes, the clypeal area sloping steeply down- 

 wards, the posterior margin very shallowly emarginate. There is a 

 strong tooth at each posterior angle, and another tooth of the same 

 size placed nearer the middle of the posterior margin. The latter 

 and the sides, as far as the anterior border of the eyes, denticulate. 

 Just in front of the eye the margin is produced into a broad and 

 obtnsn tooth, and ends in front, near the base of the mandibles, in 

 another tooth, which is usually obtuse, but sometimes fairly angular
