head. Thorax narrower than the head, emarginate at the meso- 

 metanotal suture; pro-mesonotum convex, narrowed anteriorly 

 and posteriorly ; basal portion of metanotum rectangular slightly 

 convex, apical portion obliquely truncate. Pedicel: the nodes 

 small, the 1st node conical, rounded above, higher than the 2nd 

 and anteriorly petiolate ; 2nd node subglobose, not broader than 

 the 1st node, longer than broad ; abdomen oval. 

 Length, % 2-5-3 mm. 



Hob. Ceylon, spread through North Africa, Arabia, &c. 

 Typical M. gracillimum, so far as I know, has been recorded 

 within our limits only from Ceylon ; but the form separated as 

 var. mayri (Forel, Eev. Suisse Zool. x (1902), p. 200) is spread 

 throughout India and Burma. It differs from true M. gracillimum 

 in being dark brown with the mandibles, antennas and legs pale 

 yellow ; the basal portion of the metanotum is submargined and 

 is more abruptly truncate at apex, it is densely and very finely 

 transversely striate and opaque.

$ . A variable species as to colour : the head, thorax and legs 

 may be reddish brown, the abdomen dark brown, or the head and 

 abdomen black, the thorax yellow, or specimens may be inter- 

 mediate between the two. In all cases, however, the mandibles, 

 antennae and legs are of the same colour as the thorax, only 

 lighter. Entirely smooth, polished and shining ; pilosity almost 

 entirely wanting, consisting of a few erect hairs only, on the head 

 anteriorly and on the apex of the abdomen ; traces of a very fine 

 short pubescence on the antenna and on the tibiae of the legs. 

 Head elongate, rectangular, as broad in front as posteriorly, where 

 the occiput is slightly emarginate ; mandibles narrow, armed with 

 4 teeth ; clypeus convex, the carinse just visible, obtuse ; antennae 

 rather long, the scape just attaining the top of the head, the club 

 of the flagellum remarkably thick and massive ; sides of the head 

 straight, not convex ; eyes placed below the middle. Thorax pro- 

 portionately rather long, the pro-mesonotum somewhat pyriform ; 

 the meso-metanotal suture very distinct ; basal portion of meta- 

 notnm rectangular. Pedicel : the 1st node anteriorly with rather 

 a thick petiole, the 2nd node rounded, a very little broader than 

 the 1st node ; abdomen oval. 



Length, 1-5-2 mm. 



Hob. Spread through India and Ceylon; not recorded from 

 Burma.
