The foregoing observations are taken from preparations made from two larvae, one full fed and the other younger. They were cleared in potash and washed and put in 90 per cent, alcohol slightly coloured with Congo red for about 12 hours ; the chitin was stained well, showing good differentiation. With more material the structures may be made out with more precision and in greater detail than I have been able to do at present. The figure of the larva has been drawn from a balsam preparation; in clearing in potash the specimens get stretched to a certain extent. In drawing the figures of the mouth-parts of the larva the artist was aided by three photomicrographs taken by Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Great Britain.
