the pilosity of the antennae and legs a little more dense, the hairs 

 oblique. Head highly polished, smooth and shining, oval, the 

 occipital margin narrow, the occiptal lateral angles much rounded 

 and convex, the lateral yellowish-white spot not so long as in 

 JE. martini. Thorax with the pronotum very convex, delicately 

 transversely sculptured and shining ; the metanotum compressed, 

 longitudinally striate, rugose and opaque, the basal portion long, the 

 apical portion nearly vertical laterally, above distinctly margined ; 

 legs long and robust, femora and tibiae as in JE. martini. Pedicel

long, the anterior node rugose and opaque, the posterior smooth 

 and shining, seen from the side the nodes are roundly conical 

 and subequal ; abdomen broadly oval, constricted at base into a 

 short neck. 



Length, 4-5 mm.

 I have from Borneo specimens indistinguishable from Burmese 

 examples.

. Head, thorax and pedicel reddish brown, darkening to deep 

 castaneous brown, almost black on the abdomen ; mandibles, 

 antennae and legs a lighter red-brown ; pilosity sparse, confined to 

 a few long erect reddish hairs, slightly more abundant on the 

 antennae and legs. Head oval, subopaque, delicately rugulose ; 

 mandibles broad, armed with distinct teeth on the masticatory 

 margin. Thorax elongate; pronotum not very broad, convex, 

 rugulose and subopaque like the head, but in addition with longi- 

 tudinally elongate wrinkles, that are continued more abundantly 

 on the posterior portion of the thorax, which latter is more closely 

 sculptured and rugose ; metanotum compressed, the emargination 

 at the meso-metanotal suture slight, merely indicated ; apical 

 portion of metanotum vertical, separated from the basal portion 

 by a very distinct carina which is remarkably prominent above ;
