All the specimens are blackish, without any definite trace 

 of the yellow thoracic markings described by Becher, but 

 the remarkable male hypopygium places the identification 

 beyond question. The only other known species Avith a 

 hypopygium at all approaching this in structure is the North 

 European 7\forcij/ul(i, Nielsen. T. lutea is also peculiar in 

 its venation, most specimens having r-in jdaced slightly 

 ])efore the apex of lis, a unique character in this family ; in 

 a few wings of T. lutea the position of r-m varies from the 

 normal, being either at or slightly beyond the fork of Jis. 



Quite possibly the Trich'icera recorded from Spitsbergen 

 by i^oheman and Holmgren as T.jiana and T. liu'iiiu/is may 

 l)e this species, but there is no reason why /'. ///V'///<///.s- should 

 not occur.
