(varying from one-fourth to nearly one-third wider than long), and 

 the anterior angles are more widely rounded ; the 2nd node has a 

 shallow median groove, somewhat deeper than in Goo-peri. 



Durban (Arnold). 



This form appears to me to be very closely allied to Neuvillei, and I 

 would attach it to that species as a variety but for the fact that 

 bruneipennis, Andre, is known to me only from the description. 

 Indeed, some of the specimens determined by Forel as omniparens 

 (ISTo. 330, leg. C. B. Cooper) cannot be distinguished from Neuvillei, 

 race Cooperi.

5 . 3-5 mm. Head, thorax and petiole varying from a clear 

 yellowish-red to dark reddish-brown, the head usually paler and more 

 yellowish. Abdomen dark brown or piceous, the apical margins of 

 the segments testaceous, the 1st segment in greater part dull brownish 

 ochreous, becoming lighter towards the base. Legs dull, ochreous, 

 the antennae somewhat redder. Pilosity and pubescence sparse. Head 

 very shining, the rest of the body moderately shining. Cheeks, 

 clypeus and mandibles finely and longitudinally striate, the rest of the 

 head smooth, shallow ly and sparsely punctured, the occipital face 

 microscopically rugulose. Pro- and mesonotum very finely rugulose, 

 the mesonotum also finely striolate longitudinally ; dorsum of epinotum 

 rugulose, the rest smooth and shining. Head, excluding the mandibles, 

 as wide as, or a little wider than long, the sides fairly convex, slightly 

 narrowed in front (less so in the smaller $ $ than in the larger), the 

 posterior margin almost straight. Eyes not small, placed in the 

 middle of the sides of the head. Frontal area triangular and clearly 

 defined ; frontal sulcus distinct and extending to the middle of the 

 vertex. The scape extends back as far as the occipital margin ; 3rd- 

 6th joints of the flagellum wider than long. Pronotum not marginate. 

 Pro-mesonotal suture fairly well defined in the larger 5 5- ^ the 

 latter the mesonotum is fairly convex from side to side in front, and 

 slightly constricted on each side in front of the declivous face, the 

 latter short, oblique and feebly marginate at the sides. In the 

 smallest $ $ the declivity of the mesonotum is almost obsolete, 

 the profile of the pro- and mesonotum forming a single convexity as 

 far as the meso-epinotal suture. The latter is fairly deep. Dorsum of
