long and is raised over the base of each mandible into a small hump, 

 between these humps it is not emarginate. The scape reaches back 

 nearly to the occiput, the 2nd-7th joints of tbe flagellum as long as, 

 or hardly so long as broad. The antennal hollows are fairly deep, 

 moderately wide and as long as wide ; they are not limited externally 

 by the eyes, since their external margin is separated from them by a 

 distance almost equal to the diameter of the eye itself. The eyes 

 are small. The continuation of the antennal hollows becomes indis- 

 tinct on the vertex before reaching the narrowed portion of the 

 head. . . . The thorax is smooth, with a few piligerous punctures. 

 The mesonotum is wider than long. The epinotum has two small, 

 broad, and very obtuse teeth ; the transversely convex dorsum is 

 evenly merged into the sides, as is also the smooth and very shining, 

 steep declivity. Both the transverse suture of the thorax are 

 distinct. The node of the petiole is higher than broad, rounded 

 above. Abdominal constriction moderate.

" $ . 3"5-3"9 mm. Closely related to my ops, Emery, from which 

 it differs by its less shortened head and by its longer and thinner 

 mandibles. The very small eyes have only 4 or 5 facets. The 

 mandibles, as long as half the head, have the internal margin simple, 

 ending in an obtuse angle, and with 3 teeth at the apex, the 

 median tooth springing from the lower one. The head is a little 

 longer than wide, moderately excavated posteriorly, slightly de- 

 pressed, and without a fronto-occipital groove, and with the posterior 

 lateral fossettes very feeble and shallow. Clypeus emarginate and 

 bilobed. Frontal sinus very short. The scapes almost reach back 

 to the occiput. Mesonotum transverse ; the two thoracic sutures 

 strongly impressed ; dorsum of thorax barely convex. Dorsum of 

 epinotum longer than the declivity ; the latter with two large obtuse 

 teeth or tubercles above. Node of petiole fairly high, narrow and 

 rounded above. Abdomen truncate and projecting slightly forwards 

 in front. Abdominal constriction feeble. Head smooth, shining 

 and evenly punctured with strong and numerous punctures. There 

 are some very short striae on the frontal carinae. Dorsum of 

 epinotum reticulate and sub-opaque. All the rest shining, sparsely 

 and finely punctured. Erect pilosity almost wanting, except at the 

 apex of the abdomen. Pubescence very distinct, fairly long, yellow,
