558 . Tachinidae. 



dark; the hind margin of second to fourth segment narrowly greyish 

 white, tilis coloiir protriided triangularly or linear forwards on fourth. 

 Abdomen is sparingly haired with rather strong black hairs, especially 

 along the hind margins, and it has discai and marginal bristles, 

 on second segment a pair of marginal, on third a pair of discai and 

 marginal, and on fourth a pair of discai and a row of marginal; the 

 bristles long. Legs black. Wings brown tinged; veins brown. Squamulæ 

 white or rather glassy with a yellowish margin. Halteres pale yellow. 



Female. Similar; frons broader but not as broad as the eye; 

 inner vertical bristles present; antennæ longer than in male, third 

 joint more than thrice or about four times as long as second, reaching 

 the lower margin of epistoma; palpi rather dilated. 



Length. About 6 to 9 mm. 



T. ludio is rare in Denmark, in Stæger's collection there is a 

 number of specimens, but without particular locality, and since then 

 this beautiful species has not been taken, 



Geographical distribution: — Seems only known from Denmark, 

 Styria and Tyrol. 



Remarks: As it was one of Stæger's specimens Zetterstedt 

 described, our specimens are co-types. Pokorny's description of 

 this distinct species is quite agreeing, so I feel sure of the identity; Prof. 

 Stein has seen the species and came to the same result.
