specimens) than the sides of the frontaiia ; the fronto-orbital bristles only extend a 

 short way down the face, three or four being placed below the roots of the antennae 

 in an irregular row or patch (especially in the male) ; the third joint of the antennte 

 is about four times the length of the second ; the facialia are almost nude ; the 

 thorax is black, very hoary on the front and sides, and marked by four slender 

 stripes ; the abdomen is rather setose, having bristles both on the disc and margins 

 of the segments, it has the sides lioary, with the centre of the dorsum black, as well 

 as the hind margins of the segments ; the wings have the outer and apical cross veins 

 both nearly straight, the former being placed near to the angle of the latter. I re- 

 ceived three specimens of this rare fly from Mr. Fitch some years ago, all of wliich 

 were bred from Acronycta tridens.

Feb., 1892. 



This rather small species (6 mm. in length) has the scutellum wholly black or 



rather grey. The palpi are yellow ; the antennae long, thick and straight, the second 

 joint being very sliort, and the tliird five or six times as long ; the arista is thickened 

 for nearly two-thirds of its length, the thickened portion ceasing rather abruptly ; 

 the thorax and abdomen are grey, being coated with hoary pubescence, the former 

 has four stripes, the central pair narrow and the outer ones wide and interrupted ; 

 the abdomen is tessellated with black patches, whicli assume the form of black bands 

 when viewed from behind ; the segments are armed with rather small setae on both 

 the discs and posterior edges ; the venter is grey with white margins to tlie seg- 

 ments ;* tlie wings have the apical cross veins concave, and terminating close to the 

 apex of the wing. Not common. I found one specimen at Bingley, near Bradford, 

 in 1874, and another at Silverdale in North Lancashire in 1881 ; it is also in Mies 

 Decie's Collection. 



E. parens, Rnd., has been recorded as a British species, and in 1880 I received 

 two flies from Mr. Bignell (bred from folia Jiaincincta) which I thus named ; upon 

 further research, however, I believe that they were only varieties of jE. vulgaris, and 

 I now doubt whether E. parens is a distinct species. E. prominens, Mgn., is another 

 doubtful species, Meigen omitting the colour of the palpi. I formerly labelled 

 several specimens with this name, one of which is in Mr. Dale's collection. I now 

 think that they are also varieties of E. vulgaris. 



22.— TACHINA, Mgn. 

 Oen. ch. — Eyes nude, or finely pubescent, rather widely separated 

 in both sexes, but nearer together in the males than in the females ; 

 forehead not usually very prominent ; facial angle mostly straight ; 

 antennae nearly drooping, with the second joint elongated, and half, or 

 rather more than half, as long as the third joint ; arista bare, and 

 usually thickened for half its length ; facialia bare, or only ciliated 

 along their lower halves with short fine bristles ; cheeks nude ; fronto- 

 orbital set?e usually extending half way down the face ; abdomen 

 mostly conico-elliptical in the male, ovoid in the female, and either with 

 or without discal setae on the middle segments ; wings with the fourth 

 longitudinal vein usually bent at a sharp angle, and often furnished 

 with a spurious, or nearly spurious, cubital appendix.
