Closely ullioil to 'T. albivf])S and very liko it, but easily dis- tiniriiislicd by its very broiid wings. ; lliunix and abdonion with yellowish-red pile; the abdunicn with two longitudinal rows of black spots. Head yellowish ; front and antenna} uioro yellow; the usual bristles on the front black, the bristles on the vertical margin bright reddisli-yollow. The third antonnal joint with an almost sharp anterior corner. The oral opening longer than broad, the upi)er oral etlge somewhat drawn upwards, distinctly projecting in the prolile. The rather broad palpi and the probosci-s are yellowish; the latter short geniculate, with but moderately prolonged, rather stout Haps ; the occiput, in the vicinity of the point of attachment, grayish. The ground color of the humeral callus is yello\vi>h, that of the Ijlack- ish; the bristles of the dorsum are black, the two i)airs upon its middle are inserted uj)on very small black dots, easily overlooked. Scutelluui yellow at the tip, with four black bristles.

Feet saturate yellow. The wings are very broad and have a rounded elliptical shape. The guttate reticulation shows the most striking likeness to tl'.it of 2\ albicejis, so that the description of the hitter may 1)0 applied to tliis; the only addition to be made would b -?â â ;â¦â¢ ;â¢â , IH â â
