(29.) Plusia viridisigma, (hwte. 



Mucli larger than P. 8-scripta, not so much shaded with blackish, but of a 

 dark bluish gray, with the lines and spots distinct. T. a. line geminate, nearly 

 even, strongly defected on t. a. line. Sign much as in P. 8-scripta, bolder, of a 

 peculiar greenish-golden hue — verdigris-like. Orbicular distinct, black ringed, 

 annulus irregular, toothed on the inside, surrounded with a pale shade. Reni- 

 form narrow, upright, elongate, black ringed, with a very fine pale incomplete 

 line. T. p. line not inflected, waved, geminate. Subterminal space darker, 

 more blackish than terminal. Subterminal line very distinct, with the double 

 dentations on the interspaces between veins 2 and 4, strongly expressed. Hind 

 wings with broad diff"use blackish borders. Beneath pale, somewhat yellowish, 

 with the markings improminent. Head and thorax dark gray, like fore wings. 

 Collar and tegular with distinct transverse black shade lines. 



Expanse, 48 m. m. Quebec (F. X. Belanger). 



Stiria," n. g. 



A genus with strong characters which has its most natural position here. 

 The color is bright yellow on the primaries, so that we are reminded strongly 

 of Gortyna. The clypeus is remarkably full and exceeds the eyes ; it has a 

 heart-shaped, naked depression, not unlike that of Plagiomimicus, but with 

 less prominently raised edges and with a moderate tubercle near its inferior 

 and longer edge. The vestiture of the thorax and head is scaley, not hairy. 

 The legs are unarmed except the short fore tibiae, which have a stout, blunt, ter- 

 minal claw. The thorax is short with the extremities of the patagic squamae 

 uplifted, and in its total appearance it is like that of Plagiomimicus. The 

 thoracic squamation is dark, pearly dotted or frosted. The fore wings are large, 

 wide, triangulate, with a Plusia-like tooth at internal angle. The female ovi- 

 duct is exserted. The eyes are naked. 



(30.) Stiria rugifronsj Orote. 



The fore wings are light yellow, with a patch on internal margin at the base, 

 a larger one centrally, and the narrow inwardly irregular edged terminal 

 space, purply brown with a frosting of pale scales, and concolorous with the 

 thorax. The ordinary lines and spots are obliterate, but there are some faint 

 shaded marks on the cell and faint traces of the t. p. line. Fringes frosted 

 and concolorous with the dark terminal space which narrows to apices, leaving 

 these of the yellow ground color. Hind wings whitish, soiled outwardly, 

 without lines. Beneath pale, without marks, jH-imaries soiled, secondaries 

 whitish.
