NOCTUID.T3'. — SOIYRA. 81 



Genus CXXXVIII. — Simyra, Ochsenheimer. - 



Palpi rather shorty slighdy ascending, somewhac approximating, and very acute 

 at the apex, or parallel and slightly acute, the basal joints clothed v/ith wooUy 

 hairs, the terminal scarcely exposed ; basal joint as long as the terminal, 

 subovate, stout ; second equal in length to the other two, slender ; terminal, 

 elongate, slender, acute : maxillce short. Antennw simple in both sexes, of 

 the male stout, and pubescent within : head small : eyes small, naked : 

 ifAoraj; rather stout, wooUy, not crested: abdomen moderate, more robust in 

 the females, the sides and apex producing some tufts of hair: wings entire, de- 

 flexed during repose ; the anterior simple, not very long, broad, elongate- 

 triangular, somewhat retuse, or sublanceolate, with the apex acute, the 

 surface suffused with dusky atoms : legs moderate, anterior tibiae in the 

 males with a long spur. Larva pilose; pupa enclosed in a papyraceous web. 



Simyra, although it contains three indigenous species only, is 

 nevertheless an artificial genus, and will doubtless some day be 

 divided ; Si. maculosa differing so considerably in habit from its 

 present congeners, its wings being very glossy, the anterior some- 

 what abbreviated, broad, elongate-triangular, slightly retuse, and 

 repanded on the hinder margin, with its palpi approximating and 

 very acute ; whereas in the others the wings are but little shining, 

 very acute at the apex, and sublanceolate ; the palpi less acute 

 and parallel : the larva of Si. venosa forms a strong papyraceous 

 web, in which it undergoes its change to pupa, as does also that 

 of Si. nervosa ; but of the metamorphosis of the other species I am 

 unacquainted. 



Sp. 1. musculosa. Alis anticis ochraceis fincturd virescentibns immacnlatis, 

 venis pallidio?-ibus, posticis fuscescentibus margine saturatiore. (Exp. alar. 

 1 unc. 3 — 4 lin.) 



No. musculosa. Hiibner. — Si. musculosa. Steph. Catal. part ii. p. 102. No. 

 6350. 



Head and thorax hoary-ochraceous immaculate, the latter with a greenish- 

 brown tinge ; anterior wings plain immaculate ochraceous, with a greenish- 

 brown cast, the base palest, and the hinder margin darkest; the nervures, 

 towards the hinder margin especially, paler than the wing, and in fine speci- 

 mens slightly tinted with greenish ; cilia fuscescent, or brownish : posterior 

 wings fuscescent, with the base and nervures paler, the surface minutely 

 irrorated with fuscous atoms; cilia ochraceous-brown. Female of a paler 

 hue. 



This plain insect differs a little in colour, some examples being much darker 

 and more virescent than others.
