The proboscis is unusually short and exception- ally stout, extending beyond the face; however, it is exceedingly robust and greatly swollen at the base, strongly compressed dorsoventrally and with numer- ous, stout, bristly hairs on the outer fourth dorsally and ventrally and shorter ones at the apex. The base below has abundant, long, stiff pile; the ventral sur- face has a medial groove; a dorsal ridge is absent or vestigial. Palpus with the first segment quite small, short and more or less fused. The second segment is large, thinned and excavated and leaflike; the lateral surface bears bristles, particularly at the apex, the minute basal segment bears a tuft of long, coarse pile. Head, anterior aspect: The head is quite wide. The face below the antenna is one-third the head width; sides nearly parallel. Subepistomal area short and small, well hidden by palpus and mystax. Face pubes- cent only narrowly along the eye margin or scantdy on the ventral half. The face bears dense, matted, fine pile on the lateral third and the upper three- fourths in the type of genus, sometimes extending over the entire face. The lower, retreating portion and anterior, middle portion of the gibbous part of the face bears dense, long, weak bristles and stiff, long pile. The antenna is attached at the upper third of the head; the first segment is stout, a little longer than the second segment or about the same length; the second segment is small, knoblike distally, distinctly attenuate basally. Third segment elongate, rather slender basally, gradually widening to the middle and distally but little narrowed, except near the apex; or it may reach its greatest width near the apex, being strongly spindle-shap
