I'YRALTD.E. ANANIA. ENNYCHIA. 31 



Gexus CCLX. — Anania, Hiibner. 



Palpi four, maxiilary slender, small ; labial approximating, porrccted like a 

 beak, elongate, densely clothed with scales, the apex concealed ; triarticulate, 

 the basal joint reniform, second elongate robust, third as long as the basal, 

 ovate: wzaorjY/ffi long and spiral. Antennae long and slender, slightly pilose 

 beneath : head small, clothed with compact scales : ei^es small : thorax 

 slender : wings entire, forming a triangle during repose ; anterior acute, 

 elongate-triangular; posterior small, ovate-triangular; all marked with 

 simple blotches of contrasted colours, usually black and white : abdomen 

 rather long and slender, annulated, slightly tufted in the males, acute in 

 the females: legs long and slender; posterior tibia; with two pair of spurs. 



The species of this genus are usually of dark, almost jet black, 

 colours, more or less prettily varied, spotted, or streaked with white ; 

 the only indigenous one is black, with large white regular blotches, 

 and both surfaces of the wings are nearly similar ; by this alone, ex- 

 clusively of diversities in structure, the genus may be known from its 

 allies.

Wings deep black; anterior with two large rounded snow-white spots, one 

 before the middle, the other, more ovate, placed transversely behind the 

 middle : between these towards the costa is frequently a more or less dis- 

 tinct white dot: posterior also with two white spots of similar form and 

 location, with sometimes a smaller one on the costa : cilia of all the wings 

 black, with a small space at the tip, and a larger towards the anal angle 

 white : sides of the thorax yellow ; abdomen with the margin of the seg- 

 ments white. 



The basal spot on the whigs is sometimes very small, or almost obliterated : 

 both surfaces of the wings nearly correspond. 



Rather uncommon ; found most frequently at Darenth and Birch 

 Woods, near London, in June, and again in August. 



Genus CCLXI. — Ennychia, Treitschke. 



Palpi four, rather long, approximating in form of an acute beak ; maxillary 

 small, slender; labial triarticulate, very densely clothed with elongate 

 scales, basal joint slightly curved and longer than the terminal, intermediate
