and thorax with a broad band of dark chooolate-brown hair 

 between the wings, also a little brown hair just below the

 of each of the very long, curved, acute scutellar spines ; 

 legs very dark reddish or reddish black, with ochreous 

 pubescence and ferruginous spurs ; hind l)asitarsus straight ; 

 tegulse margined with ferruginous. Wings very brown, 

 though translucent; abdomen broad-conical, without spots, 

 but covered with very fine appressed fox-red pubescence. 

 Mandibles dark red except at base and apex ; labrum broadly 

 emarginate at apex ; clypeus minutely granular, the linear 

 margin shiuing ; flagellum dark reddish ; fourth antennal 

 joint much longer than fifth, but not nearly twice as long ; 

 mesothorax shining, with strong separate punctures ; apical 

 plate of abdomen extremely narrow. Close to M. liima- 

 layana, Bingham, but differing in details of sculpture and 

 pubescence.
