Teins of the wings are rather further apart, and the outer one is straighter than in 

 the male. I have only seen one British specimen of this rare fly, which I captured 

 in July, 1891, at G-range-ovei'-Sands, in Lancashire. 



Htlemtia festiva, Zett. 



This handsome species bears a very close resemblance to H. Mlaris, Fin., but 

 essentially differs by having only a short haired or pubescent ai'ista, instead of a long 

 haired one ; the central thoracic stripe is also straight, and not dilated into a round 

 spot, as in H. hilaris. The thoi'ax is hoary, with a central black stripe, often trifid 

 in front ; the sides are marked with an oblong or subtriangular black spot before 

 the suture, and with an elongated one behind it. The scutellum is pale grey, with 

 the margins black. The abdomen is cinereous, with a central black stripe and 

 transverse irregular cross bands, less regular ard distinct than those in H. hilaris. 

 The wings have the outer cross veins nearly straight, and a little oblique ; legs 

 black. A single male of this rare fly is in tlie Rev. E. N. Bloomfield's collection, 

 captured, I believe, near Hastings. 



Hylemyia spinosa, End. ?. 



This species bears considerable resemblance in form and colour to H. variata, 

 Fin. ; it differs, however, in having a very short, instead of a long haired arista, and 

 is rather larger. The eyes are contiguous ; the forehead slightly prominent ; the face 

 white ; the antennae black, reaching nearly to the epistome, which is a little pro- 

 jecting ; the palpi are black ; the thorax yellowisli-grey, with paler sides, and three 

 or five longitudinal black stripes; scutellum grey. Abdomen cylindrico-conical, 

 yellowish-grey, with black apex, marked with a straight, rather narrow, sub-inter- 

 rupted, black central stripe, and with narrow transverse ones, which, when viewed 

 from before backwards, dilate into small black spots on the sides. The edges of the 

 segments are armed with circles of liny black bristles ; the extremity of abdomen is 

 thickened and furnished beneath with hairy lobes. Alulae yellowish-white and 

 small ; halteres yellow ; wings slightly brunescent, with costal spine distinct ; outer 

 cross vein oblique, and somewhat sinuous, and third longitudinal vein a little curved, 

 and diverging slightly from the fourth. Legs black ; hind femora furnished with 

 spines along their whole under surfaces ; hind tibiae having scattered spines of un- 

 even lengths along their outer surfaces, and a few at the upper part of their inner 

 sides. Length, about 6 mm. I captured a single male of this fly in July, 1892, 

 near Lake Windermere. 



Phorbia inteesecta, Mgn. ?. 

 This species, which was unknown to me until very lately, is distinguished from 

 all the allied species by having partly pale or piceous legs, and is further characterized 

 by having: — Eyes of male contiguous behind; forehead slightly prominent ; frontal 

 stripe rufous or black ;* epistome slightly projecting ; face white ; antennae black, 

 very short, with the second joint wider and rather longer than the third ; arista 

 short, slightly pubescent, with the basal tliird thickened ; palpi black ; proboscis 

 with the extremity narrow, and somewhat elongated ; thorax dark brown with grey 



* Of the two male specimens which I have seen, the frontal stripe was rufous in one and 

 black iu the other. Roiidani says it should be always rufous in this species, but this is a very 

 uncertain character, varying with age.
