upon his description ; R. umhripennis, Mg., is a common small weak species, with 

 dull black thorax (<?), brownish-yellow legs and smoky wings, the female having 

 simple yellower legs. 



(3) Empis sp. ?. — I caught what I cannot doubt is a pair of a small black Empis 

 at Lagg, but the male is most remarkable as one wing has not the fork of the cubital 

 vein which is the sole distinction between the genera Empis and Rhamphomyia. 



(4) Oloma fuscipennis, Mg. — Both genus and species are omitted from Walker, 

 though mentioned in Stephens' catalogue, because they were represented in his col- 

 lection by Sciodromia immaculata {v. Walker, Ins. Brit. Dipt., iii, addenda xi). The 

 genus is distinguished from Hilara by the long terminal bristle to the antennae, 

 and from Brachystonia (to which I think it most allied) by the shorter anal cell. 

 G. fuscipennis, Mg., is the only European species, and seems widely distributed, 

 though rare. The single specimen I caught was in bad condition. 



(5) In February, 1876, in my " Notes on some British DolichopodidcB," I de- 

 scribed three supposed new species. When sending some specimens to Herr Kowarz 

 last year I enclosed my types for his examination, and I am sorry to say all three 

 species sink as synonyms. The genus Forphyrops is still an exceedingly difficult 

 one, which may account for my failure there, while the Diaphorus had been de- 

 scribed too incompletely. Forphyrops simplex = P. micans, Mg. ; P. tenuis ^=^ P. 

 prcBrosus, Lw. ; Diaphorus dorsalis =^ D. melancholicus, Lw. 



(6) Medetekus. — In my " List of British Bolichopodidm " (Ent. Mo. 

 ix, 71) I gave only five British species of Medeterus, to which I added one in 1876. 

 By the aid of Kowarz's paper on the genus in the Verhandlungen der zool.-bot. 

 Gesellschaft in Wien, xxvii (1878), I can now enumerate the following British 

 species : — 



micaceus, Lw. pallipes, Zett. flavipes, Mg. 



apicalis, var. b., Zett. miiralis, Lw. j'aculus, Mg. 



muralis, Mg. diadema, L. nigricans, Mg. 



melanopleurus, Lw. rostrata, F. truncorum, Mg. 



tristis, Zett. carnivora, Fisch. 



apicalis, Zett. (?) cBneivittatus, Mcq. 



To these I expect seven or eight more species may yet be added, and I think I 

 possess at least four not enumerated above, but which I am not yet satisfied about. 

 M. micaceus will fall under Mik's genus OligochcBtus. 



(7) This synonym is given on the authority of a letter from Loew, but I do not 

 know where Schummel described the species, nor is it given in Schiner's Catalogue 

 of European Diptera. 



(8) Syrphus nigritarsis, Zett. ?. — I captured one female of a Syrphus very near 

 S. latifasciatus, Mcq. (== abbreviatus, Zett.), but the scutellum is black haired. 

 With considerable doubt I refer this to the little known S. nigritarsis of Zetter- 

 stedt ; I have another female very similar, which was given me by the Rev. H. S. 

 Gorham, who caught it at Box Hill. The species must remain doubtful until more 

 specimens can be obtained.
