202 TORTKICINA. 



rounded, whilst in E. reyiana it is the reverse. M. Guenee gives 

 this as a var. with a mark of doubt ; but it is sufficiently distinct 

 to rank as a species. 



The imago appears in June and July, flying round the tops of 

 Maples (Acer campestre). It has been taken at Plumstead, and 

 near Bexley in Kent. 



Most probably the larva may be found feeding either in or 

 under the bark of the Maple. 



2. regiana, Zell. Alis anticis atro-purpureis ; macula magna an- 

 gulata marginc dorsali flava ; costa strigis flavo-albidis, ad 

 apicem lineis caeruleis; posticis purpureo-brunneis. $ Exp. al. 

 6-6| lin. 



Head dusky-olive drab, paler in front and behind. Face dusky- 

 olive drab above, pale drab below. Eyes black. Palpi as long as the 

 head, pale drab ; in some specimens with a slight ochreous tinge. 

 Antenna? dark fuscous and glossy. Thorax and patagia smoky olive- 

 brown. Anterior wings dull umber, merging into smoky olive- 

 brown at the base, with yellow markings on the costa, a large rich 

 yellow blotch on the dorsal margin, and lustrous blue streaks at the 

 apex. On the costa, before the middle, are two dusky geminated 

 streaks, and beyond are five simple rich yellow ones ; those before the 

 middle, each unite, and are produced into a lustrous blue streak ; of 

 the yellow streaks beyond the middle, the first and third are also 

 produced into blue lustrous streaks, the former to the inner mark of 

 the ocelloid patch, the latter to a point below the apical spot. The 

 ocelloid patch is not always defined, but is usually bounded by three 

 lustrous blue streaks, enclosing some black or black-and-yellow lon- 

 gitudinal lines. The dorsal blotch has its inner edge rounded, and 

 is truncate posteriorly (when the wings are closed the united blotches 

 assume the form of a bishop's mitre), is frequently immaculate, but 

 sometimes it has two or more spots or streaks upon the margin. 

 Apical scales broad, intense brown at the apex, sometimes speckled 

 with yellow, especially towards the anal angle ; interrupted below 

 the apical spot. Cilia glossy, iron-grey. Posterior wings and mar- 

 ginal scales rich purplish brown, the latter with pale bases. Cilia 

 whitish. Abdomen glossy, umbreous. Exp. al. 6-6-i- lin. 



A common species ; constant in size and colour ; closely re- 

 sembles E. Trauniana, but is larger. The dorsal blotch is smaller 

 in proportion to the size of the wing, and has its posterior edge 

 straight, and the anterior edge rounded. 



The imago appears in June and July amongst Sycamore- 

 trees (Acerpseudo-platanus), and appears to be generally distri- 

 buted about the country, but more plentifully in the south ; 

 also in Ireland.
