This species is in the male distinguished from bromius by the 

 erect hairs aloiig ttie upper eye-margin, and from Miki by the darker 

 abdonien and the longer erect hairs at the eye-margins ; in the female 

 it is especially distinguished by the broad upper eye-margin, finally in 

 both sexes it is distinguished from Miki by its dark venter and from 

 both the above species by its smaller size. 



T. muculiconiis is not uncommon here, though scarcely as com- 

 mon as bromitis; vicinity of Copenhagen, Dyrehaven, Søllerød, Hillerod.
