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

 head. Thorax: the pronotum broad, convex and I'ounded an- 

 teriorly : the pro-mesonotal suture distinct ; mesonotum rather 

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

 the basal portion ot the metanotum horizontal, broadening 

 posteriorly ; the metauotal 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. 



Lengthy ^ 3*o-4 mm. 



Hah. Ceylon ; Burma (Bingham) ; Tenasserim (HcmxiveU) ; 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.

g . 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, conflned 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 

 ^^•idely scattered minute punctures. Head from the front square ; 

 occiput transverse ; mandibles obscurely, longitudinally finely 

 striate ; clypeus veiy 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 shghtly raised 

 and obtuse, but not tuberculate : pro-mesonotal suture verj^ dis- 

 tinct ; the mesonotum slightly raised and laterally compressed ; 

 meso-metanotal suture deeply impi'essed ; the metauotum de- 

 pressed lower than the mesonotum, the bnsal portion transver.se, 

 horizontal, broadening posteriorly ; the metanotal 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 grooA'ed down the middle, but with a slight impression 

 posteriorly ; abdomen broadly cordate. 



$ . Eesembles the ^ , much larger : pilosity moi-e abundant, 

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

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

 antenntc and legs, with an abundant oblique yellowisli pubes- 

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

 Wings light flavo-hyaline, uervures darker.
