ate, armed with 7 teeth, the apical tooth acute. Anterior margin 

 of clypeus convex. Eyes placed at the posterior third of the sides. 

 The scapes extend beyond the posterior margin by two-fifths of 

 their length. Thorax like that of Steingroeveri, but differing in the 

 presence of a fairly distinct suture between the meso- and the 

 metanotum, and by the deeper meta-epinotal suture. The metano- 

 tum is also decidedly longer, being one-quarter as long in the middle 

 as the mesonotum. The dorsum of the epinotum is one and a half 

 times wider than long, the oblique declivity one-third longer than 

 the dorsum. Scale of petiole wider above than below, as thick above 

 as below, the summit entire and convex transversely. 



^ media. 4 mm. Colour of the head and thorax darker than in 

 the ^ maxima, more brown than red. Sculpture feebler, the surface 

 more shining, especially the head. The latter and the scapes are a 

 trifle longer. The thorax is relatively narrow, the mesonotum longer 

 than wide, (as long as wide in the ^ maxima) and the metanotum 

 also longer or nearly one-third as long as the mesonotum. The 

 metanotal stigmata are more prominent, subangular when seen in 

 profile. The declivity of the epinotum is hardly longer than the 

 dorsum. The scale is a little thicker and narrower above. Other- 

 wise like the ^ maxima. 



^ minor 31 mm. Like the Q media, but the whole colour blackish 

 brown, except the tarsi and mandibles which are ferruginous.

"^, 3 - 3-6 mm. Possibly it attains to a larger size. 



^ major. Pale chestnut brown, cheeks yellowish. Limbs slightly 

 paler than the body. Erect pilosity yellowish, fairly dense on the 

 head and thorax (a little more abundant than in Steingrdoeri), scan- 

 tier on the femora, absent from the scapes. Pubescence sparse, 

 hiding the sculpture very little. Fairly shining, particularly the 

 abdomen, the head less shining. Front of the head and sides of the 

 thorax very finely striolate, passing elsewhere into a reticulation 

 with smooth spaces, especially on the abdomen. A fine piliferous 

 puncturation all over. Head quadrate, the sides moderately convex,
