The three following genera compose the family 

 Lycanidce of Dr Leach, and the Polyommatidce of 

 S wainson. Most of them are insects helow the middle 

 size, but all are distinguished by delicate markings, 

 and many by great brilliancy of colour. The ca- 

 terpillars are oval and depressed, and termed onisci- 

 form, from their resemblance to the small Myria- 

 podce of the genus Oniscus. The genus TI&ECLA 

 has antennae gradually thickening to the apex, palpi 

 with the terminal joint short, slender, and oval, eyes 

 pubescent, and the claws undivided and very mi- 

 nute. The upper wings are triangular and entire, 

 but the secondary pair produce one or two caudal 

 appendages near the anal angle. All the species 

 are brown above, and usually have the under side 

 adorned with narrow undulating lines of pale yellow 

 or white. The larvae are never found on herbace- 

 ous plants, but confine themselves to trees and 

 shrubs.
