contrasts with the discal patch into which it extends. Paler costal 

 subapical dots. The subterminal line is brown, thick and broadly- 

 undulating. Fringe concolorous. Posterior wings gray, tinged with 

 carneous. Beneath, the anterior wings are uniform gray, with traces 

 of the exterior line. The posteriors are whitish, suffused with car- 

 neous, with discal dot, and a broad median line.

The shape and the clear white color of the renifbrm spot will at 

 once separate this species from others of the genus. It is about the 

 size and shape of 0. euroa G. & R., but is very different from it in 

 marking. 



Orthosia Belangeri nov. sp. 



Expanse 40 mm. Length of body 19 mm. 



Male antennae setiform. Front, collar and thorax rounded, un- 

 tufted and concolorous, covered with fine and spreading hair. Abdo- 

 men also untufted. The anterior wings are dull deep ochreous, 

 evenly overspread with brown scales. The interior line is deep 

 brown, thrice outwardly lobed. The claviform and orbicular spots 

 are obsolete. The reniform is nearly so above; below, it is repre- 

 sented by a large, conspicuous black spot on the median nervure. 

 The median shade is very distinct, bright reddish-brown, strongly 

 outwardly arcuate, touching the reniform spot; below this it is 

 adjacent and nearly parallel to the extericr line. The latter is 

 evident above, blackish, simple and denticulate; below, it is nearly 

 obsolete. Beyond the exterior line the ground color deepens in tint, 

 becoming purple-gray, especially in the upper part of the subterminal 

 and terminal spaces; the nervules are tinged with blackish. The 

 subterminal line is of the ground color, distinct and undulating. 

 Three costal subapical light dots. The fringe is dark, with a light 

 line at the base. The posterior wings are dark grayish-fuscous, with 

 an indistinct median line and discal dot. The fringe is yellow at the 

 base, then a central dark line, and outwardly whitish. Beneath 

 ochreous, more or less shaded with reddish-brown. Discal dots. A 

 very conspicuous, black, common line, and a dusky, common, sub- 

 terminal shade. 



Hab. Quebec, Canada. 



This species bears some resemblance to Mr. Grote's description of 

 0. infumaia, but differs very considerably from it. I dedicate it to 

 Prof. F. X. Belanger, to whom I am greatly obliged for loans of 

 material.
