Moths from New Guinea and South America 301 



an Arctiid near Spilosoma. We therefore place it provisionally in 

 Depalpata. 



Differs from D. mirabilis Roths, in the palpi being well developed 

 and porrect, longer than in Spilosoma. Frons roughly scaled, narrow, 

 and produced much as in Spilosoma. Antennae minutely serrate and 

 fasciculate ; this is not so in Agaristidae. The retinaculum bar is 

 placed on the costal vein and directed to the edge of the cell as in 

 Arctiidae, but in Agaristidae this bar is placed along the costal vein. 

 Furthermore in pridgeoni the hind wing has vein 8 anastomosing with 

 cell to the middle, and vein 5 from the point of divergence of 3 and 4, 

 all on a long stalk, the cell being very short and the discocellulars 

 strongly angled. 



Considering these characters, the insect cannot be an Agaristid and 

 must be referred to the Arctiidae. We may be dealing with another 

 new genus but until more is known about Depalpata it may not be 

 wise to create another genus. 



AGARISTIDAE. 



2. Argyrolepidia aurea Jord. angusti fascia subsp. nov. 



cf . Fore wing with a much narrower band, the reduction being 

 proximal. Hind wing with a narrower black distal margin, and deeper 

 orange area which has a nearly straight and sharply defined outer edge 

 curved posteriorly. 



Underside of hind wing with smaller orange area and broader basal 

 and costal black. 



Abdomen below with the terminal four segments scaled with orange.

3. Seirocastnia albifascia sp. nov. 



? . Fore wing black-brown, crossed by a broad white band from 

 the costa to submedian. This band has the outer edge curved and 

 more sharply defined than the inner edge ; inner edge crosses the base 

 of cellules 3 and 6 and borders the discocellulars. The band narrows 

 below vein 2 and is rounded off at this end close to the tornus. Hind 

 wing black-brown with a deep blue sheen. 



Underside with the band a little broader. Fore wing with the 

 submedian area paler. Hind wing as above. 



Antennae, head, thorax, and abdomen above, fuscous-black. Palpi 

 with the first segment yellowish-white at the side. Legs fuscous-black,
