( 381 ) XV. Descriptions of 21 new genera and 103 ncio sjiecies of Lepidoptera-Heterocera from the Australian Region. By Arthur G. Butler, F.L.S., F.Z.S., &c. [Read June 2ud, 1886.] The species described in the present paper were sent to the Museum for identification, with many other previously named species received at the Godefiroy Museum from collectors in Australia, Fiji, &c. Many of the species, as might have been anticipated, form the types of new genera, but at the same time the appearance of the greater part of them is by no means striking, their colouring being, as a rule, sombre, — of various shades of brown or grey. All the species here described have been seen by Mr. Meyrick since I wrote the descriptions. AGAEISTID^. jSIgogera, Latr. 1. ALgocera cor nig era, n. s.

Schm., fig. 27), but of a cupreous-brown colour; base white, divided by the veins, two subcostal spots near the base ; an oblique abbreviated fascia immediately below the second subcostal spot, and below it again an elongated spot on internal border ; a large quadi'ate spot crosses the discoidal cell towards its • extremity, and below it is an oblique irregular interno-median streak ; between the latter and the internal spot previously noted is a small internal dot ; beyond the cell is a broad almost 3-&haped fascia, and near the external angle a cuneiform spot; at about apical fourth is a subcostal dot ; an abbreviated series of seven dots crosses the disc almost parallel to the outer edge of the 3-shaped fascia, and is followed by a regular submarginal series alternating with a series of quadrate spots on the fringe ; all these markings are milk-white ; secondaries nearly as in ^. hicolor, ochreous, with a dark or cupreous-brown spot across the end of the cell, and TRANS.
