hind margin by nearly half their length. Eyes fairly convex, placed 

 at the posterior third. Clypeus subcarinate, the anterior margin of 

 the lobe convex. Dorsum of epinotum narrower than in the 2J., 

 twice as long as the oblique declivity. Scale of petiole thicker than 

 in the 2|, the posterior face feebly convex, the upper half of the 

 anterior face oblique and sloping backwards. Otherwise like the 2J.. 



£ media, 9 mm. Intermediate in the shape of the head between the 

 2J. and the $ minor. The sides less convex, the posterior margin less 

 emarginate, the posterior angles less rounded than in the 2j. ; widest 

 a little behind the eyes and more than one-third longer than wide.

The type of the species is confined to India and Burma. It is repre- 

 sented in the Ethiopian region by numerous races and varieties. 

 The classification of some of these forms seems to be rather confused,

 excepting race vestitus, and should perhaps be treated as varieties 

 only of the race cinctellus Gerst.

2J., 8-9 mm. Black ; scapes, anterior margin of the head and tibiae 

 dark reddish brown, femora piceous, nagellum, mandibles and tarsi 

 ferruginous. Apical margins of abdominal segments yellowish white. 

 Head and thorax dull, legs moderately shining. Head very closely 

 and finely reticulate-punctate, with a few very shallow pubescent 

 punctures on the anterior half of the cheeks. Thorax, petiole, and 

 abdomen microscopically rugulose and coriaceous, the sculpture on 

 the abdomen entirely hidden by the pubescence. The latter is 

 decumbent, yellowish white and very sparse and short on the head, 

 finer and more abundant on the antennae, longer and fairly abundant 

 on the thorax, on the sides of which and on the coxae it is almost 

 silvery white. Abdomen with a very dense, fairly long and decumbent 

 pale golden pubescence, which to the naked eye presents a more or 

 less chequered pattern, somewhat as in Plagiolepis custodiens. The
