Leria with the addition of having tlie foroliead ;ind face narrowed (retrecis), and 

 the abdomen filiform ; he named the species filifonnis. Meigen gives Fallen's 

 description and name to this flj, and like him places it together with some other 

 species in the genus Heteromyza ; he does not appear to have known it himself 

 however, and one of the species which he places with it and names //. atricornis 

 is doubtless onlj the female of the same fly (oculafa). Loew removed the other 

 species associated with it, and reserved the generic name of Heteromyza for this 

 species only, to which he has given Meigen's name of alricornis, though Fallen's 

 title of oculata lias the right of priority. Loew has taken no notice of either R. 

 Desvoidy or Haliday, and he must have overlooked the clear description given by 

 the latter of both sexes, in the Entomological Magazine, vol. i, p. 168 (1833). 

 Neither Walker nor Vcrrall mentions this species, f-he male of which is so well 

 marked ; but I have two specimens, which are easily known by their large eyes 

 and narrow hairy bodies ; one of these was found by Mr. Billups at Bromley, 

 and the other was given to me some years ago, together with other flies, by Mr. 

 Verrall, labelled Inveran, 1880, but unnamed. I have not seen the female, but its 

 description corresponds very closely with that of Tephrochlamys magnicornis, the 

 chief jjoint of difference being the colour of the antenna). 



Detomtza Zawadskii, Schum. 



This species is closely allied to D.JlaveoIa, F., but differs by being darker and 

 more dusky in colour ; the antennae have the third joint rather longer and blacker ; 

 the abdomen is of a darker brown, the wings with a brown instead of a yellow tinge, 

 with a yellow stigma, and the legs are darker. I have only seen one specimen of 

 this fly which was given me by Miss Prescott-Decie and captured at Brocklcton in 

 Gloucestershire. 



PniEOMTlA NIOEIPENNIS, F. 

 This resembles the more common species of this genus {P.fuscipennis) in size 

 and most other respects, but is generally rather larger and darker in colour and has 

 the thorax marked with five subdistinct instead of four stripes. The characteristic 

 points, however, by which it may be at once distinguished are that the forehead is 

 glistening instead of dull in front, and the face is very oblique, so that the head is 

 almost triangular, the epistome and chin being wanting ; while in P.fuscipennis 

 the face is nearly straight, the cliin large, and the epistome prominent. This rare 

 fly was also captured by Miss Prescott-Decie, at Chagford, Devon, in 1888. 



SCIOMTZA DUBIA, Fin. 



This little fly has the antennte yellow, with the. third joint half black; the 

 arista is bare ; palpi pale ; thorax brown with grey pubescence ; abdomen reddish ; 

 wings clear, with transverse veins sometimes slightly nebulous ; and legs yellow, 

 This species may at once be known by the half blackened third antennal joints. 

 Length, 4 — 5 mm. I found it near Ulverston in 188G, and Mr. Beaumont sent mo a 

 specimen caught near Wolverhampton in 1893. 



Palloptera ambusta, INIgu. 

 This well marked little species has a yellow striped thorax and a shining black
