This form has been sunk to the rank of a race by Forel, but I can 

 find only the following differences, which appear to me to be worthy 

 of only varietal rank. The node is slightly narrower posteriorly than 

 in the type, the puncturation of the head is a little larger and the 1st 

 abdominal segment a little wider. I append the following description 

 of the 3 , since that of the type is so meagre. 



3 . 10 mm. Legs, pleurae, epinotum, node, abdomen, and antennae 

 bright ochreous yellow; head dirty yellow below the antennal sockets, 

 brown above. Thorax yellow-brown. Clypeus slightly raised in the 

 middle. Frontal carinae obsolete. The eyes occupy the whole of 

 the sides of the head; the ocelli large, and situated on a raised area. 

 Antennae filiform, reaching back almost to the apex of the 1st 

 abdominal segment. Prothorax very little exposed. Pro-mesonotal 

 and meso-metanotal sutures distinct. The scutellum gibbous with 

 the sides strongly striated. Mesonotum very shallowly punctured. 

 Epinotum punctured at the sides, very shining and smooth above. 

 Node of petiole narrow and parallel-sided, rounded above and in 

 front, and less so behind. Lamellar tooth distinct but small. Con- 

 striction between the 1st and 2nd abdominal segments distinct. 

 Abdomen impunctate. The whole body clothed with a dense, downy 

 and pale pubescence.

Characters. 



$ . Mandibles sub-triangular, the masticatory margin dentate and 

 forming a distinct angle with the basal margin. Eyes placed on or 

 in front of the anterior third of the head, sometimes absent or con- 

 siderably atrophied. Meso-epinotal suture distinct, otherwise like 

 Pachycondijla. 



2 . Always winged. 



3 . As in the sub-genera.
