Allied to M. tccmessa, Per. ; the shape of the thorax is nearly 

 similar, but a little narrower proportionately, and the head is 

 narrower instead of being broader than the thorax ; the abdomen 

 and also the vestiture are similar, but in M. laccrna the basal trian- 

 gular patch ascends much further, and the band on the third segment 

 is not interrupted.

$ . Black, with a totally ferruginous red thorax, first basal 

 segment of abdomen with a small lateral white patch on each side, 

 base of second segment and the whole of the third clothed with a

 wider than the thorax, a little rounded laterally behind and sinuate 

 at the base, eyes large, set forward, ovate ; it is very deeply scrobicu-

 joint of the flagellum small, second one as long as the two following

 the second segment, covered with elongate punctures, and having on
