rated from the mesonotum by a deep and broad sulcus ; metanotum 

 prominent and very convex. Dorsum of epinotum very short in the 

 middle, longer at the sides, the declivity vertical, with raised and 

 sharply defined lateral margins, which are distinctly curved inwards. 

 First node of the petiole, seen from the side, subtriangular, the 

 anterior face slanting obliquely forwards ; the dorsal edge is thickest 

 at the sides, truncate behind. The 2nd node transverse, rectangular, 

 almost twice as wide as long, the dorsal surface inclined forwards, 

 convex transversely. Abdomen very large, somewhat flattened above, 

 very little narrowed at the base or apex, the sides almost parallel, the 

 apex widely rounded, as long as the thorax and petiole together, all 

 the segments much wider than long, the first three a little more than 

 twice as wide as long. Wings very long, the anterior subacute at the 

 apex, brownish, the nervures dark brown. 



<$ . 17-18 mm. Length of anterior wing, 16 mm. Dull; head, 

 thorax and 1st joint of petiole brownish black ; the dorsal sui'face of 

 the 2nd node more or less dark yellow ; mandibles, antennae, legs and 

 abdomen dark ochreous. Head, mesonotum and scutellum fairly 

 strongly and very closely punctured ; the dorsum of the epinotum 

 transversely and also somewhat obliquely striate ; the declivity finely 

 reticulate-punctate and also transversely striate. Petiole finely and 

 closely punctured. Abdomen finely coriaceous. Femora and tibiae 

 finely and closely punctured, slightly shining. Head, mandibles, 

 thorax and petiole densely clothed with a short, suberect, yellowish 

 brown pilosity, the hairs slightly curved. The abdomen has a fine but 

 very dense decumbent pubescence, intermixed with some longer pilose 

 hairs. Legs and antennae with a very fine and dense pubescence, the 

 pilosity on the legs less abundant and less coarse than in the $ , not 

 forming dense tufts at the apices of the joints. Head subtriangular, 

 the width between the eyes two and a half times as long as the 

 distance from the anterior margin of the eve to the posterior border of 

 the head. Clypeus produced in the middle, very prominent and convex, 

 rounded in front, with a transverse impression behind. Mandibles 

 convex lengthwise, quadridentate, the apical tooth very large and 

 acute. Antennae 13-jointed; the scape short, one quarter longer than 

 wide; the 1st joint of the filiform flagellum very small, hardly more 

 than one-quarter the length of the scape ; all the remaining joints 

 much longer than wide, the 3rd-llth joints widest in the middle. 

 Eyes very convex, occupying more than half the sides of the head ; 

 ocelli slightly raised. Thorax similar to that of the ? , but not so 

 massive ; the mesonotum less gibbous anteriorly ; the brow of the 

 epinotum rounded. The 1st node is flatter than in the ? , the posterior-
