of the apical three joints ; eyes about midway on the sides of the 

 head. Thorax : the pronotum broad, convex and rounded an- 

 teriorly ; the pro-mesonotal suture distinct ; mesonotum rather 

 flat, rounded anteriorly ; meso-metanotal suture deeply impressed ; 

 the basal portion of the metanotum horizontal, broadening 

 posteriorly ; the inetanotal spines divergent, bent a little outwards 

 towards the apex. Pedicel : the 1st joint, with its anterior flat 

 portion, somewhat transversely oval ; 2nd joint with a slightly 

 raised rounded node longitudinally sulcate ; abdomen broad. 



Length, 3-5-4 mm. 



Hob. Ceylon ; Burma (BingJiam) ; Tenasserim (Hauxwell) ; ex- 

 tending to the Malayan subregion. 



The above description is taken from specimens which I have 

 carefully compared with Smith's specimen in the British Museum.

. Dark shining brown to dark chestnut-red, the abdomen 

 anteriorly above, and in some specimens the mandibles, antennae, 

 thorax and legs, a lighter shade of chestnut-red ; pilosity almost 

 entirely wanting, confined to a few erect pale hairs on the front 

 of the head and on the apex of the abdomen ; pubescence pale, 

 exceedingly sparse, and widely but regularly spaced ; head, thorax 

 and abdomen smooth, shining, highly polished, with only a few 

 widely scattered minute punctures. Head from the front square ; 

 occiput transverse ; mandibles obscurely, longitudinally finely 

 striate ; clypeus very convex in the middle, its anterior margin 

 transverse ; antennae moderately thick, the scape long, extending 

 beyond the top of the head by about one-fifth of its length ; the 

 club of the flagellum not strongly marked, formed of the apical 

 three joints ; eyes lateral, a little closer to the top than to the 

 anterior margin of the head. Thorax comparatively narrow, the 

 pronotum deep, rounded in front, the shoulders slightly raised 

 and obtuse, but not tuberculate ; pro-mesonotal suture very dis- 

 tinct ; the mesonotum slightly raised and laterally compressed; 

 meso-metanotal suture deeplv impressed ; the metanotum de- 

 pressed lower than the mesonotum, the basal portion transverse, 

 horizontal, broadening posteriorly ; the rnetanotal spines broad at 

 base, divergent and acute. Pedicel: the 1st joint flat above, as 

 broad as long, the anterior lateral angles prominent, the sides 

 nearly straight ; 2nd joint with a broad, rounded, transverse node, 

 not grooved down the middle, but with a slight impression 

 posteriorly ; abdomen broadly cordate. 



$ . Resembles the , much larger ; pilosity more abundant, 

 fairly dense on the metathorax, pedicel and base of the abdomen ; 

 mandibles densely finely striate, opaque, covered, as are the 

 antennoa and legs, with an abundant oblique yellowish pubes- 

 cence. First joint of the pedicel thicker, concave anteriorly above. 

 Wings light flavo-hyaline, nervures darker.
