[Larvse found in a small quantity of water in an empty fish-tin upon the dust-heap behind the kitchen.—W. M. G.] Siphon and anal segment of Stefjomyia fasciuta, Fif^. 1. Lateral view of the parts: a, bowel; it will be noticed that the view of the comb is obscured, though the remaining scales are above the bowel; they are eight or nine in number. The structures are those seen with a magnification of about 60 diameters; the animal, quite unprepared for microscopic examination, lyi^o ^^^ ^ trough of formalin, or in water. The long hairs on the ventral side of the anal segment have been curtailed by the exigencies of space ; they are as long as those on the dorsal edge. The ventral beard has been denuded, and is drawn as it exists on the specimen. 2. The same siphon reversed showing the abnormal condition of the spines on the left side. 3. The three lowest spines on the left side drawn larger, though seen with the same magnification. 4. A scale of the comb drawn larger but seen with the same magnification as fig. 1. Goeldi figures more teeth on the part, but these obviously require much more magnification for 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.
