$. Resembles the ^ in colour ; the mandibles are more coarsely 

 striate, the clypeus is smooth, the front between the antennae and 

 the cheeks longitudinally striate, the head posteriorly on the vertex 

 and lateral angles coarsely reticulate. Thorax: the pronotum 

 somewhat vaguelj and transversely and the mesonotum posteriorly 

 longitudinally striate ; anteriorly the latter is smooth and pohshed, 

 the scutellum rugose, the meranotuin in-egularly striate rugose, 

 including the basal portion of the nietauotal spines. Pedicel : 

 the nodes rugulose, opaque ; abdomen smooth, pohshed and 

 shining. Wings hyaline ; nervures brownish. 



d . Light chestnut-yellow, the apical margins of the abdominal 

 segments more or less broadly brownish black; head and thorax 

 somewhat densely pubescent, in places rugulose, giving them a 

 dull subopaque look : head on each side of the ocelli longitudinally 

 striate. ISome few striae on the mesonotum posteriorly and on the 

 basal portion of the metanotum, traces of the same on the apical 

 face of the latter. Pedicel obscurely rugulose, subopaque ; abdomen 

 smooth, shining, but not highly pohshed. Wings flavo-hyaline ; 

 nervures yellowish.

 desert parts of the country. 



Var. subcarinata, Smith, is slighter, more slender and lighter in 

 colour, often nearly smooth ; it occurs in Bengal, Burma, and 

 Tenasserim, and extends down to Borneo. The colonr and the 

 rugosity, as well as the pilosity, vary very much ; but, so far as a 

 very long series has enabled me to judge, the one species with 

 many slightly differing local races extends through India, Ceylon, 

 and Burma.

^ . Head thorax and pedicel brown ; mandibles and abdomen 

 yellow ; the antennae and legs lighter brown than the thorax ; 

 entirely smooth, shining and polished, except for a few vague 

 longitudinal striae on the sides of the metanotum, and numerous 

 small piligerous tubercles scattered on the head and thorax ; 

 pilosity yellowish, long, blunt at apex, most plentiful on the 

 antenime and legs. Head from the front nearly circular, the 

 front convex, the eyes prominent ; mandibles not striate, narrow, 

 broadt^ning towards the masticatory margin, which is oblique, 

 armed with 4 acute little teeth ; clypeus convex, rounded anteriorly ; 

 antennte very long and slender, much longer and more slender 

 than in M. bnimwa, the scape extending beyond the top of the 

 head by half its own length. Thorax narrower than in J/, brunnca ; 

 the pronotum higher, not convex, raised in front and formed on each 

 side above into two prominent tubercles, the propleuric are armed
