A HUNDRED NEW BEITISH SPECIES OF BIPTERA. 



BT G. H. YEERALL, F.E.S. 

 (Concluded from 2^- 202). 



58. TacJiydromia {Platypalpics) alhiseta, Pz. : at Brandon and 

 "Wicken Fen in July, also at Eawley in June. 



59. T. stigmatella, Ztt, : this is distinct from T. compta, Walker 

 and I caught eight (6 c^, 2 ? ) at Braemar on July 23rd, 1873. 



60. Campsicnemus pectinulatus, Lw. : I caught eight (6 (^ , 2 ? ) 

 of this little species at Brandon on July 10th, 1877. The males have 

 almost unarmed legs, the middle femora bearing only an entire row of 

 smallish inconspicuous bristles, and the middle tibiae having about five 

 email bristles behind on the basal half. 



61. Micromorphus albipes, Ztt. : this tiny species puzzled me for 

 years ; it is common on seacoasts, and by its attitude in the sweeping 

 net I was convinced it belonged to the DoUchopodidce, but I could not 

 succeed in naming it until assisted by Mik, who had formed the genus 

 Micromorphus for it in 1878. Amongst other places I have caught it 

 at Bognor, Wisbech and Aberlady, and also at Wicken Fen. 



62. Syrphus decorus, Mg. : Mr. J. E. Fletcher caught a few speci- 

 mens of this at Middleyard Copse, near Worcester, of which he gave 

 me one caught on May 3rd, 1873. I believe all previous records of 

 S. decorus as British relate to S. auricollis, Mg. 



63. S. lapponicus, Ztt, : a female from Pitlochrie caught on June 

 29th, 1870, was named by Loew as certainly this species. Loew 

 seemed clearly to distinguish this from S. arcuatus and S. luniger ; 

 unfortunately the latter is the only one I know well. 



64. Melanostoma duhia, Ztt. : Loew is equally confident about the 

 distinctness of this species, and names positively one female caught 

 at Dareuth on May 5th, 1S68. 



65. Chilosia cynocephala, Lw. : I rather doubtfully refer to this 

 species a half-dozen specimens (5 ^,1 ? ) caught at various places 

 within a few miles of Newmarket. 



QQ. Orthoneura brevicornis, Lw. : Loew named as this species a 

 specimen given me by the late Mr. D'Orville. 



67. Chrysogaster virescens, Lw. : Loew also named as this a spe- 

 cimen I caught at Eannoch on June 26th, 1870, and I have since 

 taken one specimen each at Loch Maree, Ivybridge and Lyndhurst. 



68. Melanophora atra, Mcq. : this, which may be a variety of M. 

 roralis, L., is common in Wicken Fen.
