This species is quite similar to tenebricosa., but is a little more 

 distinctly greyish pruinose, especially the female, and the thoracic 

 squamula is restricted and narrow as in M. grisea. Otherwise the 

 dividing characters are: Eyes in male not touching, the frons above 

 about as broad as the antennæ; frontal stripe velvet black. Wings 

 with a somewhat large costal spine. Squamulæ white. 



The female is, besides by the more distinct pruinosity, distin- 

 guished from tenebricosa by the upper orbital bristle being directed 

 outwards, not downwards. 



Length. About 6 mm. 



M. buccalis seems to be very rare in Denmark, I know only one 

 specimen, a male, from Grib Skov, taken on ^/g (Kryger). I have 

 besides seen a female, kindly sent me from Dr. Villeneuve.
