PYRAI.in.ft. MARGAIUTIA. 47 



The species of this genus may be better known by the margarita- 

 ceous or pearly hues of their delicate mostly yellow, or pale straw- 

 coloured wings, which are in general rather faintly streaked with 

 transverse lines, than by the structure of the palpi, as the genus at 

 present stands. 



The genus, as here regarded, is evidently a very artificial one, and 

 doubtless requires considerable curtailment, as well as a remodelling 

 of its contents. I have endeavoured, by means of external characters, 

 to resolve it into the Hitbnerian genera, with some slight modifica- 

 tions, as will be seen by a comparison of it with his arrangement, given 

 at the end of this volume. 



A. Anterior wings narrow, long; posterior moderate, orange or 5'ellow, with 



a dusky or black border : — Epischina, Hiib. 



tSp. 1. diversalis. Alis anticis exflavo-fuscis, maculis lineisque obscurioj-ibus, 

 posticis Jlavis, fascia marginali interruptd nigricante. (Exp. Alar. 1 unc. 

 4lin.) 



Py. diversalis. Hubner. — Ma. diversalis. Steph. Catal. ii. 164. No. 6807. 



Head, thorax, and anterior wings yellowish-brown, the latter with two ob- 

 scure waved streaks, with two dusky spots between, one small, the other 

 larger and reniform ; on the extreme hinder margin is a row of minute 

 black dots ; cilia yellowish-brown ; posterior wings dull orange-yellow, 

 with an irregular interrupted dusky fascia on the hinder margin ; cilia dusky- 

 yellow. 



The only example I have seen of this beautiful and distinct species 

 is in the collection of the British Museum; it was taken near Bristol 

 in July 1815. 



B. Anterior t^ireg-5 narrow, long, acute; posterior small, of uniform colours: 



palpi long, ascending, rather obtuse : — Mksographe, p. Huh. 



Sp. 2. asinalis. Alis anticis elongatis, cano-cinereis ?naculis sirigisijtte fuscescen- 

 tibus, posticis cinereis strigd unicd saturatiore. (Exp. Alar. I unc. 3 lin.) 



Py. asinalis. Hiibner, Py. pi. 29. f. 183. — Curtis, G. col. 175. 



Anterior wings elongated, of a hoary-ash-colour, or fuscescent; with an 

 obscure dusky streak towards the base, to which are attached two spots 

 anteriorly : in the middle towards the costa is a pale fuscous circle, and 

 behind it a very flexuous streak, to which one or more fuscous clouds are 

 attached within : cilia short, glossy ash : posterior wings ashy, or pale 

 fuscous, with a faint darker oblique streak : cilia pale ashy-brown. 



The first examples I saw of this species were taken near Barnstaple
