Chrysotimus concinnus Zett. in Wilts. — I took a female of this apparently rai-e 

 Dolichopid in Broomsgroove Wood, near Savernake, Wilts, on July 23rd, 1914. 

 Unfortunately I did not recognize it at the time, so did not search for more 

 specimens — T. W. Kirkpatrick, 7th Eifle Brigade, The Deanery, Ely, Cambs. :

" DiPTERA Danica." By William Lundbeck. Part V. Lonchopteridae, 

 Syrphidae. Copenhagen : G. E. 0. Gad. London : William Wesley and Son . 

 594 pages, 202 figures. Published July 1st, 1916. 



Once again we have the pleasure of welcoming the appearance of another 

 " Part " of Mr. Lundbeck's very excellent work on the Danish Diptera. The 

 present Volume is perfectly uniform in character with all its predecessors, and, 

 like them also, it is noted for very evident care in pi-eparation, lucid descriptions, 

 and illuminating figures. The arrangement and nomenclature are the same as 

 that of Kertesz' " Katalog palaarcktischen Dipteren, 1907," and differs in only 

 a few minor respects from that of Verrall's "British Flies," Vol. VIII, the chief 

 differences being as follows : — 



while Mr. Lundbeck has pointed out an evident error of identification on 

 Verrall's part with regard to Orthoneura elegans Mg., the British species being 

 0. geniculata and not elegans. Only two species are described as new to science 

 by the author — Penium dubium and Orthoneura intermedia. 



A comparison of the species recorded from the two countries (Denmark and 

 England) is always interesting. In the case of the Syrphidae the total number 

 of species appears to be approximately the same in each case, viz., about 210 ; 

 but of these about 30 species (after allowing for probable synonyms) and four 

 genex-a are fotmd in Denmark but not in Britain ; and about 3(5 species and six 

 genera (seven if Psarus be considered British) are found in Britain but not in 



Denmark, as follows ; —
