Cadmium-yellow; vertex and occiput medianly, mesonotum posteriorly in the angle formed by the notauli, black (fig. 1); scape above and flagellum very dark brown to black; hind tarsi very dark brown to black with flavescent pilosity; the apical tergites above commonly with a small dark mark; ovipositor red, the sheaths brown with flavescent pilosity; wings slightly and evenly infumated, except at apex, where they are decidedly darker, that is to say, in the forewing the apical half of the 3rd cubital and 2nd discoidal cells, and the apical fourth of the 2nd brachial cell, and in the hind wing the apical third of the radial, about the apical third of the cubital, and the extreme apex of the discoidal cells; the majority of the wing-veins dark redbrown, but black in the basal half of the forewing; in the forewing, the stigma, the costal vein (as opposed to the subcostal vein), and the medial at base, in the hindwing all veins at base of wing, and the majority of the anal vein in both wings, yellow testaceous, but often appearing rather darker owing to setae.
* In previous papers I have in a number of instances inadvertently used the term toruli when referring to the facial depressions (invaginations leading to the tentorial apodemes). In one or two instances, however, this term has been correctly applied by me, namely, in referring to the antennal sockets, but the context should be sufficient to indicate where the errors have occurred.
