groove are three external dorso-central bristles. Scutellum 

 gray. Calyptra large and white. Kälteres yellow. Ab- 

 domen conico-cylindrical, the iirst segment narrow and blaek, 

 the second, tliird, and fourtli segments, cinereous, with an 

 irregulär interrupted black band on the sides of the hinder 

 margins of each segment; the nnder sides of the second and 

 third Segments are a little riifescent and translucent ; there are 

 large macrochetae both upon the margin and disk of the three 

 last Segments. Wings slightly brunescent, rather short, with 

 a long costal spine, and with the fourth longitudinal vein 

 curved at the angle ; the apical cross vein is also a little bent 

 outwards, the onter cross vein is rather sinuous , and the third 

 longitndinal vein has two or three rather long bristles at the 

 base. The first posterior cell is open at the end and terminates 

 a little before the apex of the wing. Legs black, tarsi long, 

 with large pnlvilli and some long hairs at the end ; bind tibiae 

 with a few long bristles of uneqnal lengths on their outer sides. 



A Single male of this well marked species was found by 

 Mr. P a s c e at Folkestone on the sea coast of Kent in England. 



This insect is rather anomalous for it differs in two points 

 from those given as characteristic of the Genus Aphria, 

 lirstly the frontalia in the male are narrow so that the eyes are 

 approximated , while they are described as being nearly equally 

 wdde apart in both sexes; secondly the middle abdominal 

 Segments have discal setae instead of bciug unarmed in the 

 middle. R. Desvoidy in his first diagnosis of J/?/«-m does 

 not mention either of these points. and Meigen in his de- 

 scription of Tochina longirostris in his 4^'' Vol. says nothing 

 about 'the abdominal macrochetae; the later characters , given 

 to the genus have evidently been taken from one or two species 

 only, but if new ones occur possessing the chief points of 

 structure bout differing in one or two minor points. I think it is 

 better to retain them in the same genus than to form a new one 

 for their reception.
