STRUCTURE OF FEET. 53 Legs rather long (when extended flatly, they appear very long), ofgreat strength, and tawny yellow in colour, variously ringed, orclouded, or otherwise varied, with brown or black. Each foot (or tarsiis) is terminated by a pair of claws, each of thepair being formed of one large, very strong, much curved, black claw,at the outside of which is placed another much shorter and thicker,forming a kind of thumb-like appendage to the main claw. See figurebelow. On placing the curved claw in a good light, it can be seen. Foot of Hippobosca equina, showing double claws, central process, and longprickly bristle ; also portion of side of claw of H. maculata (also magnified), showingparallel grooves and saw-edge. (with the help of magnifying powers) that the lower parts of the sidesare furrowed by minute grooves placed parallel to each other, andthat the lowest part of the claw has, running beneath it, a regularlyserrated, or scalloped, edge, each groove running down to a notch inthe saw-like edge. This structure I have also observed in the IndianForest Fly, Hippubosca mnculatn ; see figure accompanying of ]witio7iof a curved claw very much magnified. Consequently on this peculiarstructure, when the fly presses the sides of the curved claws together,they form a kind of flat-sided forceps, perfectly adapted for holdingfine objects like hairs, amongst which the presence of the i
