small and obtuse teeth at the base, and a larger obtuse tooth in the 

 middle of the basal margin. 



Antennae 12-jointed, the scape reaches back to the posterior edge 

 of the eyes. All the joints of the flagellum are broader than long, 

 except the terminal joint which is as long as the four preceding 

 taken together. 



The thorax is parallel-sided, depressed dorsally but not marginate 

 and without trace of sutures ; the declivity of the epinotum finely 

 marginate. 



Head and thorax smooth, sparsely and finely punctured, a hair 

 being inserted in each puncture. The puncturation of the petiole is 

 much coarser, that of the 1st abdominal segment a little smaller, the 

 rest of the abdomen finely punctured. The petiole is half as wide 

 again as long, truncate anteriorly and posteriorly, round above and 

 not marginate; below and in front there is a large rounded projection. 



The 1st abdominal segment is as wide at its base as the posterior 

 edge of the petiole, widening towards the apex ; the 2nd segment is 

 longer than the petiole, but the 2nd and following segments are 

 together shorter than the petiole plus the 1st segment. The legs are 

 hirsute.

The type species does not occur in our region, but I have thought 

 it best to reproduce the original description which applies in the 

 main to the following variety.

£ . This is a little larger than the type, and has the petiole 

 sparsely punctured.

$ . 4 mm. Castaneous brown, scape, apical joint of flagellum and 

 legs ferruginous. In some specimens the head and abdomen darker, 

 almost piceous. Shining • thorax, petiole and 1st abdominal segment 

 largely and coarsely punctured, the punctures of the petiole being 

 particularly large. Head and 2nd abdominal segment with smaller 

 and more abundant punctures, the remaining abdominal segments 

 finely and sparsely punctured ; antennae finely and closely punctured. 

 The whole body covered with rather long whitish recumbent hairs,
