between V? and ^7?. My male specimens have been examined by ^ 

 Pater Schmitz. 



Geographical distribution: — Hitherto known from Denmark, 

 Holland, Belgium and Germany; the species is about as common as 

 aterrima and will no doubt be foimd to be widely distributed. 



9. Beckerina Malloch. 



Species of medium size. Frons rather broad, with a middle 

 furrow ; three nearly straight rows of strong bristles with f our bristles 

 in each row; one pair of smaller supraantennal bristles which are 

 directed upwards and diverging. Eyes hairy. Antennæ inserted rather 

 low down, of medium size in the male, smaller in the female, arista 

 dorsal, pubescent, Palpi not small, with dense, but somewhat short 

 bristles. One long lower postocular bristle; two strong oral bristles 

 directed forwards and a couple of quite small genal bristles or hairs. 

 Thorax with one pair of dorsocentral bristles. Scutellum with four 

 strong and equal bristles. Mesopleura bare. Abdomen with the seg-

 small; it is unsymmetrical, of the side prolongations from the tergite

 at the hind corners the hairs are a little longer. Legs without tibial 

 bristles, only a small apical and spur-like anterior bristle on hind
