bases. First joint of petiole long, twice as long as deep ; 2nd joint a 

 little wider than long, the sides moderately angular. 



The larger £ £ differ in having the sculpture stronger, the pilosity 

 longer, the scapes shorter or not extending beyond the occipital margin. 

 The 2nd node is also wider and more acutely angular at the sides. 



$ . 6'6-7 - 2 mm. Dark brown or piceous, the anterior half of the- 

 head, the paraptera and the median portion of the nodes above paler ; 

 the 1st segment of the abdomen also paler or reddish-brown. Antennae, 

 mandibles and legs ferruginous. On the abdomen the pubescence is 

 intermixed with longer pilose hairs; legs and antennae with a long 

 and oblique pubescence. Head dull, closely and longitudinally striate, 

 on the sides also reticulate. Mesonotum and scutellum smooth and 

 shining, very sparsely punctured, the base of the mesonotum also 

 superficially rugulose. Epinotum transversely striate and dull. Petiole 

 rugulose and dull. Abdomen shining, finely and sparsely punctured. 

 Mandibles smooth, shining and punctured. Head quadrate, a little 

 wider than long ; eyes placed in front of the middle. Clypeus with a 

 feeble median carina. The scapes do not reach the posterior margin of 

 the head. Mesonotum fairly flat above. Epinotal spines stout, blunt 

 at the apex, one-third as long as the space between them. The petiole 

 differs from that of the 1/ in having the posterior-dorsal face of the first 

 node much wider than long, and steeper, the dorsal edge more deeply 

 emarginate. The 2nd node has larger lateral teeth, which are strongly 

 curved backwards. Wings brownish-yellow, the nervures pale brown. 



<$ . 5'5 mm. Black ; antennae, legs and mandibles brownish -yellow,_ 

 abdomen dark brown. Pilosity and pubescence as in the $ , the 

 sculpture on the head and epinotum finer than in that sex, but 

 on the posterior half of the mesonotum somewhat stronger. Head 

 trapezoidal, highest behind, much wider in front than behind. Eyes 

 occupying the anterior half of the head ; ocelli very prominent. 

 Scapes not much longer than the 2nd joint of the nagellum; the 1st 

 joint of the latter globose, the remaining joints all longer than wide. 

 Mandibles 4-dentate, finely aciculate. Clypeus gibbous. Mesonotum 

 similar to that of the $ but more convex in front ; scutellum slightly 

 gibbous, not flat as in the $ . Epinotum with two very obtuse and 

 flattened angles. Dorsal edge of 1st node much less deeply emarginate 

 than in the $ ; 2nd node finely and longitudinally striate, subdentate 

 at the sides. Wings as in the £ .

 should be amended so as to accord with the name of the locality in which it 

 was found.
