On page 84, article 9, volume 68, Proc. U.S.N.M. (1926), under the head of Eumacronychia, there appears the following statement: “This genus, erected by Townsend in 1892, has long been considered synonymous with Hilarella and has never been generally accepted.”

Allied to basicornis Kngt., but easily distinguished by the much larger size, shorter rostrum which only attains posterior margin of sternum, and by the fuscous markings of the male.

Female. Length 8-9 mm. Body shining black clothed with whitish hairs; the following parts rufous; palpi, middle of mandibles usually, labrum, antennae except the two basal segments above (in some specimens the two basal segments are entirely dark), legs beyond trochanters, and abdomen beyond the basal plates. Segments 2-5 of the abdomen above with dark transverse bands across the middle most pronounced on basal segments and decreasing apically. Wings yellowish with stigma and veins, except costa, brownish.

Brachyrhinus rugosostriatus Goeze (rugifrors of American writers, in part, not Gyllenhal.

The preceding part under this general title was published in 1921 (Can. Ent. 53 : 132-137). The species discussed at this time are all included in the very extensive series of these flies belonging to the Canadian National Collection and kindly sent to me for determination by Mr. Curran. I am greatly indebted to Mr. Curran, and to the various collectors of the material, for the opportunity of studying this important series of specimens.
