HOMALOMTIA, Bouche. 

 H. ruscuLA, Fall. 

 This species is undoubtedly synonymous with Meigen's H. fioricola. Fallen's 

 description of the male of K. fuscula agrees with Meigen's description of the same 

 sex of H.Jloricola, but not with Meigen's account of S. fuscula. The latter author 

 seems to have apxilied Fallen's name to an entirely different species, for he says in his 

 description of H. fuscula that the abdomen of the male is short, whereas it ought to 

 be oblong (langlich), as he correctly states it to be in his description of S. fioricola. 

 He also says that it shews brown reflexions, which are not present in the latter species. 

 Lastly he states that in the female of H. fuscula (that of H. fioricola was unknown 

 to him) there is a wide frontal stripe, whereas it is a characteristic feature of this 

 species that the space between the eyes in the female is unusually narrow ; not much 

 more than double the width of that in the male. 



Fallen's name being the oldest must supersede that given by Meigen, and the 

 synonymy of the species will therefore stand thus — 



H. puscuLA, Fall, et Zett. 



fioricola, Meig. et Schiner. 

 cilicrura, Rond. 



H. spissATA, Meade. 



My friend Mr. Verrall has pointed out to me that this species was described by 



Loew under the name of H. coracina,* before the part of my annotated list appeared, 



in which I recorded it as a new species, I therefore hasten to make the correction. 



The name of spissata must therefore sink into a synonym, thus — 



H. COEACINA, Lw. 



spissata, Mde. 



H, EosEBii, Eond. 

 Mr. Verrall has recorded the capture of this pretty little species in England,t 

 and kindly gave me two specimens. The male has the thorax of a shining metallic 

 brownish-black colour, with white sides and shouldei's. The scutellum is brown with 

 a reddish margin. The abdomen is of a clear transparent whitish yellow colour at 

 the base, and black at the apex. The legs, with the exception of the tarsi, are bright 

 yellow. 



H. TEIANGULIFERA, Eond. 



On carefully examining the small specimens of Homalomyia, which I had 

 placed together under the name of H. serena, I found that they consisted of two 

 distinct species, nearly allied, but presenting several decided points of difference. 

 One of these I now propose to place under Rondani's name of triangulifera, as his 

 description agrees with it more closely than that of any other species that I can find, 

 with the exception perhaps of H. luguhrina, of Zetterstedt ; and also because the 

 name is very appropriate ; one of the most distinguishing characters being the 

 presence of three very well defined triangular spots on the dorsum of the abdomen. 



The male is of a shining black colour on the thorax, the shoulders and sides
