Copied from Mr. Cambridge's figure. remarkable manner from any known type of Trombidium, and running counter to all the characters hitherto used-to define that family, but still unquestionably belonging to it. It will be seen that the mouth in this species is a mere hole on the anterior part of the underside of a bladder-shaped body, and the parts in it seem, in Mr. Cambridge's figure, too indistinct to be depended upon. It has all the aspect of a larva with eight legs, the larvae of Trombidium having little or no appearance of a head or mouth. If it had been a six-footed insect with the form of a mature species, that might have been explained away by supposing that all the changes of skin were not over, and that, as sometimes happens, the mature form was anticipating the final change and complete perfection of form ; but here the signs of maturity that last appear are present, while the form of the body still remains that of a larva. It was found by our old friend Mr. Hardy in the Cheviot Hills. Genus Erythr^us. This genus is distinguished from Trombidium, by having no division of the body, and by the last joint of the legs being very long and slender. It is glabrous, semi-transparent, and has a pink or carmine shade of 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 Murray, Andrew, 1812-1878.
