margin, the metallic spots the same asin P. rogationts, but rather smaller, the fringe dark brown ; 
secondaries dark brown, with the fringe paler in colour; the underside of both wings silky brown: head, 
thorax, and abdomen brown, the legs pale brown, the palpi brown; the antenne brown, and as long as 
the primaries. Expanse 13 inch. 
Hab. Panama, Volcan de Chiriqui (Arcé, in mus. D.; Ribbe, in mus. Staudinger).— _ 
Ecuabor, Sarayacu (Buckley). 
This species is distinguished from all others of the genus by the antenne being as 
long as the primaries. Ecuador specimens do not differ from those from Central 
America. 
17. Plusia abrota, sp. n. (Tab. XXX. fig. 19.) 
Primaries dark brown, the costal margin banded with short brown markings, with a pale waved brown band 
crossing from the costal margin near the apex to the inner margin, a wide metallic golden-brown streak 
from the base below the cell, on the upperside edged with a very fine white line, and a wide metallic 
golden-brown submarginal line extending from the apex almost to the anal angle, the fringe dark brown ; 
secondaries blackish-brown, palest at the base, the fringe pale greyish-brown: head, thorax, and abdomen 
dark brown, the hairs at the base of the thorax golden-brown; the antenne and legs brown. Expanse 
1? inch. 
Hab. Mexico, Jalapa (FP. D. G.), Coatepec (Brooks). 
A fine distinct species. The specimen captured by Mr. Godman is figured. 
THYRIA. 
Thyria, Guénée, Sp. gén. des Lép. vi. p. 357 (1852) ; Walker, Cat. xii. p. 934. 
Four species were placed in Thyria by Walker, all from Tropical America: .two of 
these, I believe, are conspecific, and one is referable to another genus. 
1. Thyria ditissima.

(Champion; Ribbe, in mus. Staudinger)—CoLomBia, Antioquia; Guiana? ; Ecuapor; 
Brazit, Rio Janeiro 2; AMAZONS, Para}. 
This insect may not really be @istinct from 7. amenita (Cram.); but the latter, 
according to Cramer’s figure, has the secondaries clouded almost to the base with 
yellowish-brown. I believe 7. aurifundens, Walk., to be the same species.

Walker included in this genus one species only, Phalena (Noctua) severa, Cram.,
