R. H. Jleade: Specie! novae Tachinidarum descriptio. '-115 



groove are three external dorso-central bristles. Scutellum 

 gray, Calj^ptra large and white. Hal teres yellow. Ab- 

 d m e n conico-cylindrical , the first segment narrow and black, 

 the second, third, and fourth segments , cinereous , with an 

 irregular interrupted black band on the sides of the hinder 

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

 third segments are a little rufescent and translucent; there are 

 large maerochetae both upon the margin and disk of the three 

 last segments. Wings slightly brunescent, rather short, with 

 a long costal spine , and with the fourtli longitudinal vein 

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

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

 longitudinal 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 pulvilli and some long hairs at the end ; hind tibiae 

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



A single male of this well marked species was found by 

 Mr. Pa SCO 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, 

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

 approximated , while they are described as being nearly equally 

 wide apart in both sexes: secondly the middle abdominal 

 segments have discal setae instead of being unarmed in the 

 middle. R. Desvoidy in his first diagnosis of Aphria does 

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

 scription of Tachina longirostris in his 4*'' Vol. says nothing 

 about the abdominal maerochetae; 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 bj)ut differing in one or two minor points. I think it is 

 better to retain them in t' i same genus than to form a new one 

 for their reception.
