. Annals of the Entomological Society of America. Entomology. FOUR NEW TETRANYCHIDS. By E. A. McGregor, Bureau of Entomology. The following species of phytophagus mites from the Southeast are of considerable economic importance and are herein described for the first time. Tenuipalpus bioculatus sp. no v. Female. Body crimson, with two rather well-defined eye-like spots on cephalothorax. Widest at posterior comers of cephalothorax, two- thirds as wide as long. The cephalothorax is narrowed considerably anteriorly, and the abdomen tapers to a rounded tip. The body is armed with a pair of weak spines on the anterior body margin medially, similar spines immediately before and behind the emarginate eyes, six at the posterior tip of the abdomen, a few along the body margin, and scattered ones dorsally. The cephalothorax is hardly half as long as broad, with the anterior margin convex; the palpi greatly resembles the Tetranychus type, the penultimate joint bears a strong claw, and the terminal joint (thimib) bears a "finger". The legs are relatively. Fig. 1. Tenuipalpus hioculalus. Right leg I, dorsal view (enlarged 650 times). stout, crenulated; forelegs in length three-quarters the width of cephal- othorax; four anterior tarsi blood-red in life; all legs bearing several lateral hairs, and a terminal bristle in length equalling the three distal segments; the trochanter of the foiu anterior legs with a lamellate hair placed dorsally; the tarsi with several terminal appendages including a pair of closely appressed claws, a very long bristle, and the four capi- tate hairs, so frequently seen in Tetranychus. Length, mm.; width (hind margin of cephalothorax), mm. The egg is thickly elliptical in linear outline, and measures .096 mm. by .067 mm. It is blood red in color from the first. The eggs are depos- ited with the long axis perpendicular to the leaf, closely packed (like those of Coccinellids), often comprising clusters of several htmdred. Type No. 19
