the margins black. Covered all over with a fine and close pubes- 

 cence. The pilosity on the head and thorax very scanty, apical 

 abdominal segment and clypeus with some longer yellowish-red hairs. 

 Mandibles with short yellow hairs, very minutely striate and coarsely 

 punctured, the apical tooth large. Head, thorax, and abdomen very 

 finely and closely punctured. Head wider than the thorax, the sides 

 convex, the posterior margin widely and rather deeply emarginate ; 

 including the mandibles the head is as long as the thorax. Clypeus 

 raised but not projecting in the middle, excavated at the sides 

 between the anterior margin and the antennal sockets. Frontal 

 ■carinae nearly as wide in front as they are long. Antennae reach 

 back as far as the petiole, flagellum gradually incrassate towards the 

 apex, 1st joint slightly longer than the 2nd. Eyes moderately large, 

 separated from the base of the mandibles by about their own length. 



Pronotum, seen from above, one-third longer than the mesonotum, 

 excluding the scutellum. Epinotum compressed at the base, 

 widening and raised towards the declivity ; the latter oblique but 

 not descending abruptly from the dorsum. Petiole, seen from above, 

 convex in front, with the posterior face concave in its lower half, 

 vertical and shining, the upper half sloping slightly forwards. The 

 anterior and posterior surfaces meet at the sides and above in a 

 rather sharp edge. Ventral lamella produced into a blunt tooth 

 pointing backwards. The abdomen is more shining than the rest 

 of the body. Constriction between the 1st and 2nd segments 

 almost obsolete. The 1st and 2nd segments sub-equal. Legs 

 slender. 



? . 8-9 mm. Black ; mandibles castaneous with the margins 

 black. Antennae and all the tibiae and tarsi more or less ferruginous ; 

 femora dark reddish brown. Puncturation, pubescence, and pilosity 

 as in the £ . Head very little wider than the thorax and as long as 

 the same, excluding the epinotum. 



Pronotum as long as the scutellum. Epinotum wide, the dorsum 

 very short or about two-thirds the length of the scutellum ; the 

 declivity very steep, rounded above, the lateral margins slightly 

 prominent. Wings pale yellowish, nervures and stigma dark yellow. 

 Otherwise like the £ . 



S . 6-6*5 mm. Black ; all the tarsi and last four joints of the 

 flagellum brownish yellow ; scape and basal portion of the flagellum 

 brown ; femora and tibiae at the extreme base and apex ferru- 

 ginous. Pubescence similar to that of the ? ; a few long hairs on 

 the scutellum, epinotum, and node. Mesonotum finely punctured 

 laterally at the base ; scutellum with very faint rugosity, the rest of
