Rh are rather short, the tibiæ being considerably shorter than either the femur or tarsus; the middle tibiæ are longer and terminated by two spurs, whilst the hind pair, of equal length, have a pair of spurs at the middle and another at the tip. The mediastinal vein of the fore wings is rather short: the postcostal one emits two branches before the junction with the ordinary transverse vein; the first of these branches is straight and extends to the costa of the fore wings, but the second coalesces with the postcostal vein at a short distance beyond the junction of the postcostal and transverse veins, but almost immediately branches off again in a straight line extending to the costa; a third branch is also emitted, which is forked before it reaches the costa, the lower branch of the fork extending to the tip of the wing. The median vein extends in three branches to the extremity of the wing, the ordinary transverse vein arising at the base of the last three branches. This transverse vein emits two straight veins, which extend to the extremity of the wings. The bridle consists of several very fine setæ. We are so completely ignorant of the character of the smaller exotic Lepidoptera, that we shall only venture to observe, respecting the relations of this group of moths, that they seem to be intermediate between the Lithosiidæ and aberrant Tineidæ.

The head, thorax, and fore wings of D. equestralis are of a beautiful pea-green, the latter being ornamented with numerous spots and lines of silvery white, more or less confluent; three of these
