ANOTHER HUNDEED NEW BRITISH SPECIES OF DIPTERA. 



BY THE LATE G. H. VEKRALL, F.E.S. 



(Continued from Vol. xlvii, i)age 19). 



[These Notes were practically complete at the time the late Mr. Verrall 

 published the names of the species in the April number of this Magazine for 

 last year, and were only held back by him for the piirpose of adding- a short 

 description of Scatopse coxendix ; of this description he left the rough notes 

 which I liave written up, and though the resulting description is very short, it 

 is sufficient to distinguish the species. — J. E. Collin, December ISth, 1911.] 



1. Sciara longiventris, Zett. : I do not find this rather conspicuous 

 species in oiir British List, hut Mr. R. C. Bradley took several speci- 

 mens at Sutton Park in May to June, 1895, and I took an example at 

 Colwick in June, 1889. It is rather a farce to add single species of 

 Sciara to our Lists, when at least 1 50 more species of the genus should 

 occur in England. 



2. Leia^ terminalis, Meig. : I am hound to consider a male Leia 

 taken by Dr. J. H. Wood at Stoke Wood, Herefordshire, as belonging 

 to this species, though I must admit that I should like to see the 

 species of Leia in considerable numbers before coming to a certain 

 conclusion about their distinctness. 



3. Boletina hasalis, Meig. : among several unidentified species of 

 Boletina, I think this one can be named with practical certainty. I 

 have specimens from Ivybridge, Frant, Westhide, Caswell Bay, and 

 Bettws-y-Coed. 



4. Platyura nigricauda, Strobl : without expressing any opinion 

 as to the value of the specific characters used at present in this genus, 

 I may, without much doubt, refer two males (which I possess) to this 

 species ; one was taken at Llangollan on July 17th, 1888, and the other 

 at Bewdley on September 1st, 1892.
