Head: Length about 1/6 longer than wide, cheeks nearly straight, slightly converging posteriorly, postocular bristles dilated into a small head, rather shorter than the eyes. Eyes small, occupying about one-third the length of the head, rounded, not protuding, not.produced on the ventral surface. Posterior ocelli opposite the anterior one-third of the eyes. Antennae nearly twice as long as the head. Segments all short and thick; 2-6 about equal in length; 1 and base and inner border of 2 concolorous with the head; remainder of 2, and 3 yellowish brown; 4 darker; 5-8 dark brown. Mouth Cone rounded at the apex. Prothorax nearly as long as head and nearly twice as wide as long, a long and short bristle on each posterior angle and a conspicuous one in the middle of each side, all capitate. Pterothorax about as wide as prothorax. Wing membrane with a brown area at the extreme base, plainly narrowed in the middle. Fringing hairs sparse but long, no interlocated ones. Legs rather short, fore tibiae slightly enlarged, tarsi devoid of teeth. Abdomen long and slender, 4.5 times as long as broad, prominently banded with dark brown and orange, sparsely provided with bristles some of which are capitate and some pointed. Tube about half as long as the head. Described from a single ? taken from ironweed (Vernonia) at Gainesville Aug. 7, 1919. The species is remarkably close to H. bellus Hood and Williams in most characters but is longer (smaller in most measurements except the abdomen); the eyes are not produced on the ventral side; and the intermediate segments are shorter. merely writing about this subject thinking that i will be 18
