slightly greyish, not at all mixed with black ; tegulse clear 

 testaceous ; winj^s nearly clear, costal nervure ferrufjinous ; 

 ahdonien rather broad, but parallcd-sided, clothed with 

 greyish-white hair, hind mar<riti.s of the se^jmonts with con- 

 spicuous entire white hair-band.s ; apex rounded, irregularly 

 serrulate, not euiaru:inate ; apex ot" venter with a rather 

 large tooth on eacii side and a small one in the middle. 



Has the general aspect of M. Toionsendiaiia^ from which its 

 front legs and abdominal structures at once separate it. The 

 non-cmnrginate apex of abdomen allies it with M. manifestay 

 but it has not the long median ventral apical tooth of that 

 insect.

 differences. Hind border of scutellum and sides of meso- 

 thorax conspicuously bounded by white pubescence; apical 

 teeth of mandibles very little developed j ventral scopa white, 

 black on the last segment.

J . — The abdominal bands, described as white by Cresson,

 and very distinct, and the second and following segments 

 have their dark portions clothed with black hair. Ventral 

 scopa white, black on the apical segment and apex of penulti- 

 mate one, white, however, at extreme base of apical segment.
