11 . 6 mm. Head dark reddish-brown, thorax and abdomen very 

 dark brown or almost black, legs and antennae ferruginous. The 

 whole body abundantly clothed with a long, yellowish and decumbent 

 pubescence, shorter on the legs and antennae. Erect pilosity almost 

 absent. Fairly dull, only the occipital lobes and the abdomen having 

 a slight gloss. The whole head, excepting the occipital lobes, finely 

 and longitudinally striato-rugose, the spaces between reticulate- 

 punctate and partly rugulose. Occipital lobes fairly closely but not 

 coarsely punctured. Mandibles very convex externally, strongly 

 punctured, some of the punctures coalescing to form longitudinal 

 striae. Thorax with a fine and somewhat superficial fundamental 

 reticulation, which is strongest on the epinotum ; there are a few 

 irregular rugae in addition, more or less transverse on the promeso- 

 notum. Nodes rugulose. Abdomen very finely punctured, rugulose 

 at the base. Head quadrate, parallel- sided as far as the occipital 

 lobes, the outer margins of which curve slightly inwards, one-eighth 

 longer than wide, deeply, angularly and widely excised behind. 

 Clypeus carinate, the anterior margin straight. Frontal carinae 

 strongly divergent, not extending beyond the anterior fourth of the 

 head. Eyes placed at the anterior fourth. Scapes not reaching the 

 middle of the head. Pro-mesonotal suture fairly distinct ; the 

 posterior lateral angles of the pronotum considerably rounded. 

 Mesonotum hardly depressed in the middle, its scutellar portion 

 vertical behind, and bearing a transverse torus above. Dorsum of
