208 Tachinidae. 



Female. Somewhat different in colour. Frons as broad as the 

 eye. Thorax and abdomen yellowish grey or greyish yellow; stripes 

 on thorax narrow, and the longitudinal stripes on abdomen narrow 

 and weak to almost disappearing. Ovipositor strong, compressed 

 and knife-like, curved a little downwards, of brownish black colour; 

 it protrudes backwards or is more or less hidden in sixth segment. 

 Wings somewhat yellowish at base, with the veins more or less 

 yellow.

B. gnjlloctona is more common in Denmark than the other species; 

 Hillerød, Frerslev Hegn, Tisvilde, at Skelskør and in Jutland at 

 Skeide, Sønderborg, Frijsenborg, Horsens and Skørping; the dates 

 are ^^e — ^Vs- It occurs especially on umbellifers. 



Geographical distribution: — Europe; towards the north to 

 Southern Sweden (according to specimens sent from Ringdahl). 

 The species has been bred from Podisma alpina.

Male. Quite similar to grylloctona. Antennæ a little longer, 

 nearly reaching lower margin of the eye. Upper forceps with the 

 apex curved more inwards, and more hook-like. Penis long and 

 slender with the apical part less thickened. Wings a little brownish 

 towards base.

 grylloctona and thus more yellowish in colour with much weaker 

 black markings. Ovipositor of a similar shape, but less curved and 

 less protruding.

B. gladiatrix is rare in Denmark, I possess only one male and one 

 female. Dyrehaven and Ruderhegn (the author); they were taken in 

 August. 



Geographical distribution : — Europe down into France ; towards 

 the north to southern Sweden according to a specimen sent from 

 Mr. Ringdahl, and, as far as I can see, belonging to this species.
