With reference to the above, Paragus albifrons, if a good species, is 

 certainly British ; onr Pipizella heringi is almost certainly Lundbeck's Penium 

 dubium, in which case P. heringi is known from Denmark only ; our Pipiza 

 higubris is probably identical with Lundbeck's P. austriaca, in which ease 

 P. lugubris is at present known from Denmark only ; Syrphus arcuatus of Lund- 

 beck is a different species from S. arcuatus of Verrall ; ovir Brachypalpus 

 bimaculatus is very possibly identical with Lundbeck's B. laphriformis ; while 

 the following are very doubtfully distinct British species : — Pipiza fenestrata, 

 Melanostoma dubium, and possibly Syrphus nigricornis. 



Lundbeck gives much interesting information and many descrijitions of 

 the larval and pupal stages ; of special interest being his description and
