192 LEPIDOPTERA. 



permanent effect. One has been secured in a gas lamp at 

 Exeter, and one in Wicken Fen, Oambs. (by Mr. W. H. B. 

 Fletcher). Two or three casual specimens each, on the south 

 coast of Kent, near Dover and Folkestone, close the record 

 for these islands. Abroad its range is extensive. Spain, 

 Turkey, Syracuse, and the rest of Southern Europe, Central 

 Europe, Asia Minor, Syria, Armenia, Persia, Turkestan, 

 Afghanistan, Beloochistan, China, Japan, the mountain 

 regions of Central Asia, Mauritius and Northern Africa. 



Genus 93. THALPOC HARES. 



Antennas slender and short, ciliated ; palpi short, ascending ; 

 eyes naked, without lashes ; thorax smooth but with a minute

 small, trigonate, rather brightly coloured but the normal 

 pattern indicated ; hind wings plain, with an angulated cross- 

 bar, and vein 5 arising near to vein 4.

 groups of micro-lepidoptera.
