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^.

1. ALgocera cor nig era, n. s. 



Allied to j^. diver sa {Agarista diver sa, Walk.), the pattern of 



the primaries being very similar to that species and to A. epliyra 



(Herr.-Sch., Aussl. 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
