252 LARGE EMERALD-MOTH 



The caterpillar has six pectoral, two abdominal, 

 and two anal feet. It is green, with a yellow line 

 on each side and reddish warts on the back ; and 

 feeds on the elm, lime, alder, birch, &c. The moth 

 appears in the end of July, frequenting woods and 

 meadows, but is not very frequently met with in 

 any part of Britain. It has, however, been found 

 in Askam Bogs Yorkshire, in Kent, Surrey, near 

 Reading, in Warwickshire, and many other parts of 

 England, and on two or three occasions near Rae- 

 hills in Dumfries-shire, as well as at Cramond near 

 Edinburgh. As a genus, Hipparchus is distinguished 

 by the following characters : antennae pectinated in 

 the males almost to the apex, the pectinations 

 ciliated ; antennae of the female simple ; proboscis 

 spiral, much shorter than the antennae ; palpi pro- 

 jecting nearly in a horizontal direction, and approxi- 

 mating at the tip ; the radical joint very short, the 

 second very long, the terminal one lanceolate, free 

 from hairs, and somewhat pointed; upper wings 

 covering the under pair when at rest, the latter 

 with the hinder margin dentate.
