pubescence. Head subquadrate, hardly narrowed in front ; occiput

 opaque in front, punctulate and longitudinally rugose ; behind very 

 shining and with large scattered punctures ; clypeus striate, nitidu- 

 lous ; mandibles shining, striate at the base. Thorax dull, punctulate 

 and transversely rugose, the pronotum gibbous on each side ; meso- 

 notum with a distinct scutellum and a transverse torus ; epinotal 

 spines erect, a little shorter than the dorsum of the epinotum. First 

 segment of petiole with a squamiform lobe (= the nodal portion) and 

 emarginate above ; 2nd segment more than twice as wide as the 

 1st, not much wider than long, the anterior margin arcuate, the sides 

 obtusely angulate, densely punctulate, dull ; the first abdominal 

 segment punctulate at the base, 7 mm. long, the head without the 

 mandibles 2 - 6 mm. x 2*4 mm. 



" ^ . Piceous, mouth, antennae, articulations of the legs, tibiae and 

 tarsi rufescent, dull, very densely punctured, the abdomen shining, 

 except at the base ; head ovate, cheeks longitudinally rugose, man- 

 dibles striate, pro- and mesonotum without prominences ; dorsum of 

 epinotum sulcate in the middle, the epinotal teeth triangular and

% . Mandibles deep castaneous brown, antennae and tarsi yellowish- 

 red, all the rest of the body black. Apart from the colour, this 

 variety also differs from the type of the species as follows : The 

 sculpture is much stronger everywhere. The head, excepting the 

 median area of the clypeus and the mandibles, is dull all over, 

 the reticulate and fundamental sculpture extending over the occipital 

 lobes. The thorax is much more coarsely rugose and the sutures are 

 deeper, also the transverse impression on the mesonotum. The basal 

 third of the abdomen is dull, very sharply reticulate. The scanty 

 punctures on the abdomen are also deeper and larger. Otherwise like 

 the type of the species. 



. 4T mm. Femora and coxae piceous ; tibiae, scapes and basal 

 half of the flagellum very dark brown ; mandibles, tarsi and apical 

 half of the flagellum ferruginous, the rest of the body black. Legs 

 and apical half of the abdomen smooth and shining, the rest of the 

 body dull, very strongly reticulate-punctate, and much more strongly 

 sculptured than in the type of the species, which it otherwise 

 resembles.
