epistoma, and the thickened hind tibiæ; the female may be distin- 

 guished from the female of notabilis by the shorter antennæ, a Httle 

 broader epistoma, and the quite black middle metatarsi; from the 

 female of caligatus it may be distinguished by the greyish yellow 

 epistoma, and likewise by the black middle metatarsi; fmally it has 

 in both sexes the basal antennal joint much more yellow. 



D. lineatocornis is very rare in Denmark, only four specimens, 

 three males and a female, have been taken; Copenhagen, Amager, 

 Damhusmosen, Utterslev Mose (the author). The dates are ^''/o — ^h. 



Geographical distribution: — Northern and middle Europe down 

 into Germany ; towards the north to southern Sweden ; it seems on 

 the whole to be a rare species. 



Remarks: The females of the three species notabilis, caligatus 

 and lineatocornis show some resemblance to the female of pennatus, 

 but the antennæ are less yellow beneath the basal joint, and have 

 the second joint quite black; also pennatus is larger.
