Male. Frons considerably broader than the eye. Orbits blackish 

 above, downwards together with cheeks whitish or pale yellowish, 

 silvery; jowls grey; frontal stripe velvet black. Vibrissæ somewhat 

 streng. Orbits finely haired; cheeks with somewhat bristly hairs,

 foiir black stripes, the median narrow, abbreviated behind, the 

 lateral interrupted at the suture. Thorax black-haired. Abdomen 

 black, somewhat shining, the three last segments with a narrow, 

 white pruinose front band, more or less interrupted in the middle, 

 and shifting to brown according to view, Abdomen is black-haired, 

 second segment with a pair of marginal bristles, third with a pair

 Jutland at Skørping (the author); the dates are in July. 



Geographical distribution: — Europe down into Italy; not known

106. TricliopaFia B. B. 



This genus is very nearly related to Admontia and in most
