182 IIAUSTELLATA. — LEPIDOI'TERA. 



of the anterior wings, with the posterior stigma on the latter much less den- 

 tatetl, and somewhat obUterated ; the third ordinary striga is barely visible, 

 and is united by a stout black streak to the second, towards the inner margin 

 of the wing, the space anterior to which, on the costa, is fuscous, and bears 

 the ordinary stigmata, white or pale cinereous or ochraceous, the anterior 

 delicately margined with black, the posterior with a black edge on its ante- 

 rior margin, and vanishing into the ground colour of the wing on its posterior : 

 towards the hinder margin of the wing are two acute dusky or brownish 

 streaks, as in Calocarapa exoleta, and the hinder margin of the wing is fuscous, 

 with black lunules : cilia fuscous, with pale streaks : posterior wings fusces- 

 cent. 

 This species varies considerably in the intensity and brilliancy of its colours 

 and markings, but the less denticulated posterior striga serves to distinguish 

 the varieties from those of the following insect. 



Ha. remissa is also a somewhat rare species, though in some 

 places and seasons a considerable number of specimens have oc- 

 curred: I have taken it occasionally at Coonibe and Darenth- 

 woods in June, and near Ripley and Hertford. " Cottingham,

Head and thorax fuscous : anterior wings clouded with fuscous, with the costa 

 of a deeper hue, and having three distinct whitish spots near the apex, which, 

 with the usual stigmata, is of a cinereous hue : the rest of the wings is of a 

 similar tint, with a large wedge-shaped fuscous spot behind, and another 

 oblong darker one in the middle, towards the inner margin; towards the 

 posterior margin is a whitish striga, which is very much waved, and strongly 

 dentate : the posterior wings are whitish, with the nervures and outer margins 

 dusky. 



The resemblance between this and the foregoing insect is almost 

 too close to warrant their separation; but as both species vary 

 greatly, and each variety retains its own peculiar, though obscure, 

 characteristics, I have, with Mr. Haworth, considered them distinct, 

 as I conceive that it is not the quantum but the constancy of dif- 

 ference that constitutes a species, as I have elsewhere endeavoured 

 to show. This insect has been taken at Coombe and Darenth 

 woods, and in Epping Forest : also in Yorkshire.
