The karyotypes of twelve species that possess microchromosomes are briefly described and compared with those of related species that do not have microchromosomes. The species with microchromosomec include several Sphaerophoria sp. (2n=6+6 micro.); Volucella pellucens (L.) (2n=10+8 micro.); Volucella zonaria (Poda) (2n=10+app. 30 micro.); Volucella elegans Loew (2n=10+35 to 45 micro.); Eristalis abusivus Collin (2n=10+10 to 16 micro.); Merodon avidus (Rossi) (2n=12, but a female from Spain 2n=14+5 or 6 micro.); Mallota marguerita Will. (2n=10+7 or 8 micro. including X and Y); Somula decora Macq. (2n=10+8 micro.); Sphecomyia vespiformis (Gorski) (2n=12 + XY + complexes of micro.); Xylota nemorum (Fab.) (2n=10 + about 20 micro. in certain individuals from western North America). These microchromosomes are generally not heterochromatic and are normal in behaviour except that they tend to clump in meiosis I. An origin from sex chromosomes seems possible. The karyotypes of Volucella inanis (L.) (2n=12) and of Eristalis transversus Wied. (2n=14) are also described briefly for comparative purposes and those of several other species of Syrphidae having karyotypes not previously described, are mentioned in the text.
