Fig. 1. Proboscis of Musca osiris, emerged from the subcranial cavity (R: rostrum, H: haustellum, L: labella) (60 x). Fig. 2. Proboscis of Musca domestica in dorsal view (Lb: labrum) (86 x). Fig. 3. Labrum (Lb) and hypopharynx (Hp) of Musca domestica (mentum removed) (78 x). Fig. 4. Labrum (Lb) and hypopharynx (Hp) of Musca domestica in ventral view (mentum removed) (130 x) Fig. 5. Labrum (Lb) and food channel (F) of Musca osiris in ventral view (mentum and hypopharynx removed) (130 x). Fig. 6. Labrum (Lb) and food (F) channel of Musca osiris, seen from the entrance of the food channel. The base of the removed hypopharynx is indicated by the salivary duct (Sd) (360 x). Fig. 7. Labrum (Lb) and hypopharynx (Hp) of Musca autumnalis, bent out from the axis of proboscis (86 x). Fig. 8. Proboscis of Musca autumnalis in dorsal view (the tip of labrum /Lb/ is immediately below the lamellae of the labella, latter in a scraping position) (100 x). Fig. 9. Labella of Musca osiris, in anterior view. The lamellae of labella are open above the food channel: this gap allows the labrum to reach the surface of feeding (600 x). Fig. 10. Labella of Musca domestica, in anterior view. The gap between the lamellae of labella is discernible above the entrance of the food channel (Ef: entrance of food channel, P: prestomal teeth, Ps: pseudotracheal rows) (150 x). Fig. 11. Prestomal teeth of Musca domestica; a chitinous membrane (Cm) chains them to each other (lettering as in Fig. 10) (660 x). Fig. 12. Prestomal teeth and the chitinous laths (C) connecting them with the labella in Musca domestica (1300 x). Fig. 13. Labella (L), prestomal teeth (P) and pseudotracheal rows (Ps) in Musca autumnalis (200 x). Fig. 14. Prestomal teeth and chitinous laths (C) connecting them with the labella in Musca autumnalis (540 x). Fig. 15. Prestomal teeth of Musca autumnalis (480 x). Fig. 16. Prestomal teeth (P) and chitinous membrane (Cm) connecting their bases in Musca osiris (Ef: entrance of the food channel, Ps: pseudotracheal rows) (440 x). Fig. 17. Prestomal teeth (P) and chitinous laths (C) connecting them with the labella in Musca osiris (720 x). Fig. 18. Prestomal teeth (P) and chitinous membrane (Cm) connecting their bases in Musca osiris (Ps: pseudotracheal rows) (1000 x). Fig. 19. Prestomal teeth (P) and chitinous membrane (Cm) connecting their bases in Musca osiris (400 x). Fig. 20. Prestomal teeth (P) and chitinous laths (C) connecting them with the labella and with the pseudotracheal rows (Ps) (1000 x). Fig. 21. Prestomal teeth (P) and chitinous laths (C) connecting them with the labella in Musca autumnalis (540 x). Fig. 22. A lesion on the surface of living tissue (cornea) caused by sucking of a house fly. A small heap indicates the entrance of the food channel (ef) (p: the place of the tearing of prestomal teeth, 1,2,3: layers of epithelial cells) (600 x).
