I maintain that tlie interests of the science of Dipterology is best served by- 

 retaining the name Oscinis. 



Siphonella Imvigata, Fall. — I cannot understand why Becker considers 

 Ixvigata, Zett., distinct from Ixvigata, Fall. Fallen knew only the female and 

 Zetterstedt expressly stated " Feminam descripsi secnndimi specimen, qiiod 

 Fallen ante oculos habnit" while Zetterstedt's description cannot apply to 

 Siphonella oscinina but does apply to Haplegis tarsata. The name Ixvigata, 

 Fall, sinks as a synonym of Haplegis tarsata. Fall. 



Siphonella oscinina. Fin. — This was recorded as British by various old 

 writers and may be re-instated in the " List," for I have seen specimens from 

 Herefordshire, taken by Dr. Wood, from Cambridgeshire, taken by Mr. C. G. 

 Lamb, from Glamorgan, taken by Col. Yerbury, and I caiight a specimen myself 

 at Tuddenham (Suffolk) in August, 1906. 



*Siphonella tristis, L. — This species with halteres and antennae dark and 

 proboscis not so long as in oscinina is not uncommon at Walton-on-Naze (Essex) 

 in June, I have also taken it in Suffolk and Col. Yerbury found it at Gravesend 

 (Kent) and again at Porthcawl (Glamorgan). Becker considers it a synonym 

 of nigricornis, v. Eoser, however v. Eoser's description of six words is not only 

 hopelessly inadequate bixt does not agree in as much as the front tarsi are never 

 black in tristis. 



*Siphonella longirostris, Lw. — We possess Loew's species in England xuiless 

 there are two or more species with dull brownish-grey thorax, shining black 

 pleurae (except meso-and ptero-pleurae) and pale legs. 



*Siphonella duinensis, Strobl. — The combination of svich characters as black 

 halteres, milk-white wings, a large vertical triangle and entirely pale tarsi 

 renders the distinguishing of this species an easy matter. I have had it 

 separated under a MS. name for some time past upon specimens taken in 

 Siiffolk(Woodbridge and Butley), Essex (Walton-on-Naze), and Kent (Belvedere 

 two specimens taken by Col. Yerbury). It was described by Strolil from 

 specimens taken in the lagoon of Diiino near Trieste. 



*Siphonella pumilionis, Bjerk. — This is a most distinct yellowish species 

 with almost confluent dark stripes on the thorax (like a Chlorops). I have seen 

 only thr(!e British specimens, one taken by Mr. Verrall at Abbot's Wood (Sussex) 

 on Jime 28th, 1867, another by Dr. Capron probably near Shiere (Surrey), and 

 a third by Dr. Sharp in the New Forest (Hants) 



Siphonella capreola, Hal. — This is now recognised as an Elachijptcra 

 (Melanochseta) and is identical with aterrima, Strobl. 



* Siphunculina xnea, Mcq. — A male was found by Mr. Verrall at Cusop 

 Dingle (Herefordshire) on July 11th, 1905, and a female at Eingmer (Sussex) 

 on April 17th, 1867. I do not iinderstand why Becker refuses to accept the 

 generic name Siphunculina ; Eondani sufficiently differentiated the genus in 1856 

 and evidently used the name Madiza in the sense we use Siphonella ; moreover 

 in Bigot's collection under the name Siphunculina brevinervis Eond. there is a 

 specimen labelled "Typ" (probably sent to Bigot by Eondani) wliich is a speci- 

 men of S. senea, ^Mcq.
