Our s'pecies have not been apportioned but described under JRhyncholophus {Ery- Ihracvs). Most of them, like E. simplex Banks (fig. 57), are uniform reddish in color, but Erythraeus cinctipes Banks has prettily banded legs, and {E.) Atomus maculatus l^nmks (fig. 55) has several large pale spots on the dorsum, while E. parvisetosus Ewing is almost wholly black. E\ving has recorded finding a specimen of this species carrj'- ing several of its larvse on its back, but perhaps they were more probably red bugs. One of our species, E. longipes Banks, has such extremely long legs that it resembles a minute phalangid. Several species of the genus Eatoniana occur in southern Europe and northern Africa; they are remarkable on account of a plume of long hairs on the hind legs. The South American genus Cflec'i/;so?na differs irom. Erythraeus and Smaridia in having two little buttonlike elevations near the tip of each metatarsus, as shown in figure 59. Family TROMBIDIID^. The "harvest mites," as they are popularly called, are recognized by the body being divided into two portions, the anterior (cephalothorax) bearing the two anterior pairs of legs, the palpi, mouth parts, and eyes; the posterior (abdomen) is much larger and bears the two posterior pairs of legs. The mandibles (fig. 64) are chelate; at least there is a distinct jaw or curved spinelike process. They also differ from the allied Rh^Ticholophidae in that the last joint of leg IV is not, or very slightly, shorter than the penultimate, and in that the last joint of leg IV is not swollen. The last joint of leg I (fig.
