specific with the type-specimen of S. maculipes BECK, (see below). (Their abdomen is without transverse bands, third antenna! joint is less than twice longer than its width, contrarily to the four times longer third joint as given in the description of antennata BECK.). This is why I regard Sapromyza antennata BECKER, 1895 to be an unrecognizable species. S. brunnescens BECKER, 1895; 225, 189, is a new synonym of Sapromyza albiceps FALLÉN, 1820 (= decaspila LOEW, 1857) (synonymy by COLLIN, 1948); = octopunctata v. ROSER, 1840 nec WIEDEMANN, 1830; = octopunctella HENDEL, 1908 (as nom. n. for octopunctata v. ROSER). Material studied: det. BECKER: 1 9 : "Kaltwasser, 11 /6, 29451", "brunnescens BECK"; 1 9 : "Polen" "Brunnescens"; 1 9 : "SCHNABL'S S. 36555", "brunnescens BECK." (all the above data are in BECKER'S handwriting, except for "Polen"), det. CZERNY: 2 9 : "Austria sup., Almsee, CZERNY" "Sapromyza 8 punctata v. ROSER" ; 1 9 : "Austria sup., Kremsm.", "Sapromyza 8 punctata v. ROSER". The colour of the frons, of the third antenna! joint and palpi, the position of the anterior de pair, the short t.

L-t

p section of the wing wholly agree with COLLIN'S description (1948). S. atechna BECKER, 1895; 211, 185, is a new synonym of Sapromyza sexpunctata Meigen, 1830. Unfortunately, I received a male ("Görz, 40749" — "atechna BECKER") (in BECKER'S handwriting) instead of the 9 holotype from the Berlin Museum. This specimen was determined to be, after careful genital preparation, sexpunctata MEIG. Though I have not seen the holotype, I am convinced that atechna is a synonym of sexpunctata (since BECKER was a dipterologist who scarcely knew the species he himself described). His original description differs from sexpunctata only by the lack of flacks on tergite 4. The examined male specimen, in fact has a pair of flecks on tergite 4, though it was covered prior genital preparation. S. chlorophthalma ZETTERSTEDT, 1847 sensu BECKER et CZERNY is conspecific with Sapromyza apicalis LOEW, 1847. — Material studied: 1 rf : "Chlorophthalma ZETT. ?" — "SCHNABL'S S. 36546" (BECKER'S hand-writing), S. apicalis Lw., det. L. PAPP (by study of genitalia). CZERNY had not even one specimen of this species; it is also very probable that BECKER had no more than this single specimen above. S. distichera CZERNY, 1932: 53, is a new synonym of Sapromyza quadripunctata (LINNÉ, 1766). — Material studied: syntypes: 3 9 : "Rügen, Sassnitz, CZERNY — 20. 6. 1930" (not I rf, 2 Q as given by CZERNY, 1932: 53); 1 9 : "Rügen, Göhren, CZERNY, 26. 6. 1930"; 1 9 : "S. Russland, Krim, 26. V. 1899, S. BAZHENOV, "Sapromyza distichera CZERNY" det. CZERNY; other material (det. CZERNY): 1 9 : "Stein a. D. CZERNY, 26/6. 29." All these specimens have also a pair of small black spots on tergites 5 and 6, although these tergites are covered by the preceding ones, thus, the spots can be seen only from behind. In all probability it was one of the causes, why CZERNY described this common species as new. S. leningradensis CZERNY, 1932: 56, is an unrecognizable species. — Material studied: 3 9 syntypes (all types): 1 9 : "Gouv. Petrograd, Sablino, 27. VI. Stackelberg, 1913" — "Sapromyza "Sapromyza leningradensis CZERNY" det. CZERNY. 2 9

: "CaômiHO, neTporpaa, 13. VII. 1913, UlTaKeJiboepr", "Sapromyza leningradensis CZERNY" det. CZERNY. CZERNY gave a short but comparatively good description but unfortunately the type-series consists of females only. It is very near to (or conspecific with) zetterstedti HENDEL, 1908. (Body small, arista with short pubescence, a brown spot above neck, anterior dc very short, 4 rows of acrosticals). The differentiating character given in the description namely, that zetterstedti has not a pair of dark spots on tergite 4, is a very dubious feature. S. maculipes BECKER, 1907: 383, is a possible synonym of Sapromyza sordida HALIDAY, 1833. — Material studied: 1 syntype rf

'• "Riva, 10/5. 41572" — "maculipes BECK." (BECKER'S hand-writing). COLLIN (1948: 234-235) described both the 9 ar)

d cf genitalia of sordida HAL. His descriptions fit the above type-specimen and to the specimens of maculipes that I have seen. The spot on the çf fore femur apically, the 6 rows oc acrosticals, the armature of the legs of çf also indicate the conspecificity of the two species. It is indispensable to study the types of sordida HAL. to make a final decision ; which was impossible in the course of the present work. S. nigrifacies CZERNY, 1932: 48, 63, is a new synonym of Sapromyza opaca BECKER, 1895. — Material studied: holotype 9 (Zoological Institute, Leningrad): «KOyKKH, FleTporpaa, 10. VIII. 928, ILlTaKejiböepr» — "Sapromyza nigrifacies 9 CZERNY" det. CZERNY. It is quite incomprehensible why CZERNY described a partly rotten and subsequently discoloured specimen to be new. At a certain incidence of light the pairs of flecks on tergite 4, 5 and 6 are readily perceptible; ocellar setae broken off but insertion points standing close to one another. Arista with
