1. Dichroma equestralis. A pretty moth of moderate size from the Cape of Good Hope, the head, thorax, and fore wings a beautiful pea-green ornamented with numerous more or less confluent spots and lines of silvery white, including a deeply angulated bar and an oblique apical bar emitting straight branches. The body and hind wings are silvery white slightly shaded with brown; expanding fourteen lines and a half, the wings are reflexed at rest.
2. Dichroma histrionalis. A Cape moth with a white head patched with fulvous and a white thorax ornamented with fulvous, the fore wings a splendid golden fulvous adorned with many silvery white marks edged with black scales and a white fore margin. Two divergent white bars rise at the base, four oval white patches cross the middle obliquely, and straight white bars extend to the margin; the hind wings and abdomen are silvery white, expanding twelve lines and a half.
3. Dichroma arcualis. A Cape moth one inch across, the fore wings a dirty pale brown ornamented with white markings, including a strongly furcate basal mark, a slender bar parallel to the inner margin joined to oblique white crescents, a clavate spot, and a denticulated white line toward the tip. A row of white arches diminishes along the outer margin toward the apex, the hind wings and abdomen white slightly tinged with brownish.
