2 . Head, thorax, and abdomen finely punctured ; the vertex 

 and front with rather a coarse granular appearance, the thorax 

 and abdomen more sparsely punctured than the head ; clypeus flat, 

 anteriorly truncate, the margin transverse ; median segment rounded 

 posteriorly, with a medial deep longitudinal groove, the apex 

 emarginate on each side ; petiole of abdomen flat in the middle, 

 coarsely longitudinally striate. Jet-black and shining; the clypeus 

 in the middle, a line on the scape of the antennae in front, the 

 apex of the median segment on each side, and a spot on the 

 apical joint of all the tarsi, orange ; wings deep fuscous brown, 

 with a coppery and purple eifulgence.

2 . Closely allied to and resembling M. indica, Saussure, but 

 smaller, different in sculpture, and with a few slight yellow 

 markings. Head, thorax, and abdomen punctured, the punctures 

 on the head finer and closer than on the thorax, those on the 

 abdomen widely spaced and confined to the basal two segments 

 and apical margins of the 3rd and 4th, the bases of these two 

 segments and the 5th and 6th smooth ; clypeus large, convex, the 

 apex depressed and emarginate ; the front between the antennae 

 subtuberculate ; scutellum large, with a broad, smooth, shining, 

 medial longitudinal carina; median segment finely rugose, the sides 

 obliquely truncate, smooth, with a few indistinct oblique striae, a 

 wide, deep, medial longitudinal furrow runs from base to apex of 

 the segment ; petiole with an obtuse tubercle on each side beneath 

 close to the middle, and a medial longitudinal furrow on the apical 

 half above. Jet-black ; a minute spot between the bases of the 

 antennae, another behind the eyes, an abbreviated narrow line on 

 the posterior margin of the pronotum in the middle, and a trans- 

 verse narrow line on the posterior margin of the basal two 

 abdominal segments, yellow ; the line on the basal segment inter- 

 rupted in the middle, that on the 2nd segment interrupted broadly 

 on each side ; legs black, a yellow line on the anterior tibia above, 

 and the knees and apical joint of the tarsus obscurely fulvous red ; 

 wings fuscous with a purple effulgence, the posterior wing hyaline 

 at base.
