XXIV. On Gracilaria, a Genus o/Tineidae. By H. T. 

 Stainton, Esq. 



(Continued from page 133.) 



Sp. 16. Ornissella (Douglas), Stainton. (PI. XV. fig. 1.) 



Alis anticis griseo-brunneis, strigulis costae quinque, dorsique 



tribus niveis, basim versus fusco-marginatis, 

 Ornissella, Stainton, Zoologist, 2163. 



Not closely allied to any known species ; has perhaps most re- 

 semblance to Coriscium substriga, but from this its different palpi, 

 smaller size, want of an apical hook, and differently coloured an- 

 terior wings, at once distinguish it. 



Expansion of the wings 4 lines. 



Head and face white ; palpi white, a fuscous ring at the end of 

 the second joint, and another a little before the end of the terminal 

 joint; antennae dirty whitish, with fuscous annulations ; thorax 

 fuscous ; abdomen fuscous, whitish underneath posteriorly ; the 

 four anterior legs have the femora and tibiae dark grey, and the 

 tarsi white ; the posterior legs have the femora and tibiae white, 

 the end of the latter grey, tarsi white, with the ends of the joints 

 dark grey. 



Anterior wings of a grey-brown, or ochreous, with five white 

 streaks along the costa, nearly at equal distances, and three on the 

 inner margin. The first costal streak lies not far from the base, 

 is placed obliquely, and does not reach the middle of the wing ; 

 the second costal streak is placed similarly to the first, but is 

 longer, reaching nearly to the fold ; the third costal streak, placed 

 similarly to the two preceding, but more attenuated, (a little ex- 

 panded however on the costa,) is generally rather shorter than the 

 second streak, but in one of my specimens it is continued right 

 across the wing, forming with the third inner-marginal streak an 

 uninterrupted fascia; the fourth costal streak is crescent-shaped, 

 and reaches to the hinder margin ; the fifth costal streak lies in the 

 extreme apex. The first inner-marginal streak has its origin at 

 the base, and is there very narrow, but expands into a triangular 

 form opposite the end of the first costal streak, with which it 

 forms an interrupted fascia ; the second inner-marginal streak 

 lies opposite the end of the second costal streak, forming with it 

 an interrupted fascia ; the third inner-marginal, situated at the 

 anal angle, forms with the third costal streak an interrupted fascia, 

 or else an entirely uninterrupted fascia. All these white markings
