blackish spots in front of scutellum; humeri yellow, but with 
interior hind border reddish; yellow sutural stripe narrower. 
Pleura entirely reddish, only a little darkened around the yel- 
low markings; yellow mesopleural stripe narrower; only the 
hypopleural yellow spot present, that on sides of mesophragma 
being indistinct or only indicated by a more-yellowish inner 
border in contact with the above-named spot; mesophragma 
entirely reddish and unspotted. Bristles as in the preceding, 
with anterior supra-alar bristle well developed. Scutellum 
small and short, much broader than long, yellow with a narrow 
brownish basal stripe. Halteres and squamuke whitish. 
Abdomen with long, narrow, and cylindrical stalk; first and 
second segments dark brownish, with a narrow yellow hind 
border; third segment uniformly blackish brown; fourth seg- 
ment blackish brown, with a rectangular, transverse, yellowish 
spot in middle at hind border; fifth segment yellowish, with 
broad blackish patches on sides, and with the two oval patches 
likewise black, hind border of segment entirely pale yellowish. 
Venter with blackish terminal sternites. Long, whitish, erect 
pubescence near base of abdomen. Legs reddish, femora 
broadly blackish; base of tarsi not whitish; middle femora with 
a pale yellowish base. 
Wings (Plate II, fig. 4) as in the preceding, but with second 
basal cell much longer and narrower. The pattern consists of 
an equal, dark, costal border, extending from base to tip of 
wing, surpassing a little the third longitudinal vein below; no 
spotlike dilatation at end; anal stripe not distinct or else in- 
dicated only by a yellowish shading. Prolongation of anal cell 
very long, extending about to hind border of wing. No super- 
numerary lobe at end of sixth vein. 
Note. — The present species belongs in the group with the 
Indian M. crabroniformis Bezzi, and the Burman M. destilla- 
toria Bezzi; it has likewise no developed lower orbital bristles, 
a single yellow hypopleural spot, a narrow and elongate second 
basal cell, a similar wing pattern with a broad and equal costal 
border, and with no developed anal stripe. It is, however, 
distinguished from both by the black oval patches of the fifth 
abdominal segment and by the differently colored legs. The 
species M. aequalis Coquillett, M. longicornis Wiedemann (= 
vespoides Doleschall), and M. conopoides de Meijere, evidently 
belong to the same group, but the last two are said to have 
spinose front femora.
