Die befallenen Blatter welken abo Berlin, den 9. Miirz I9Jo Deinen Brief yom 5. M. habe ich richtig bekommen. Das verheiBungsvoll angefangene Zuchtjahr hat sich weiterhin als gunstig erwiesen: Nun ist auch die Art aus Vicia faba geschlupft; es ist - und wenn Du zerspringst - nichts anderes als Dizygomyza crucifericola Hering, die somit ihrem und meinem Namen Unehre macht. Sicherheitshalber habe ich gleich gestern abend die Genitalien beider noch herausgenommen, aber auch da sind keine Unterschiede festzustellen.

Dber incisa kann ich bezgl. der Mine nichts sagen, da mir keine einzige schliipfte. Ich argwohne, de Meijere ist bei seiner Beschreibung der Larve der incisa einer Verwechselung zum Opfer gefallen. , fiige ich in einigen Puparien bei, da wirst Du Dir sofort ein Bild machen konnen, auch ohne Lupe, wie ich Dich kenne. Deine mit personlich iiberbrachte Sendung (ich weiB nicht von wem, war im Augenblick nicht da) hat eine FiiIle von interessanten Dingen gebracht. Zunachst einmal die Erweiterung un serer Kenntnis iiber die Lebensweise der Phytomyza sonderupi, denn um diese wird es sich bei den Caltha-Stielen wohl gehandelt haben.

Angebauter Substratpflanzen nie wieder gefunden6 • Da heutzutage Phaseolus viel angepflanzt wird, kannst Du vielleicht auch einmal im Juni-Juli darauf achten. Berlin, den 22. Marz I94S Recht herzlichen Dank fiir die gesandte Mine an Ranunculus sceleratus L. Die Schwierigkeit ergab sich hier daraus, dass in dem genannten Blatt zwei Minen ineinander verschlungen waren, von denen die eine die bekannte Phytomyza fallaciosa Bri. (= mimica Hering) war, die andere der neuen Art angehorte. Ich glaube, die letztere daraus isoliert zu haben, so dass sie etwa der beigefiigten Zeichnung entsprechen wird.
