Spkcies 2. — P^DiscA ANGUSTioRANA ° — (Plate LXXXI., Fig. 4) — Varies from 6 to 8 lines in expanse; 

 fore wings narrow, oblong, obtuse, of a dusky reddish colour, with a red-brown spot at the base next the inner 

 margin ; an undulated fascia from the middle of the costa to the anal angle, and another red-brown, oblique, 

 smaller, ustulated- brown fascia within tlie apical margin ; the colours of the disc and fascias variable : hind 

 wings black. A common and widely dispersed species, found in woods and gardens ; and especially destructive 

 to wall-fruit trees in the spring, by the grub devouring the young shoots and blossom buds, as described in 

 detail in my article upon this species in Mr. Loudon's " Gardeners' Magazine " above referred to. The antennee 

 of the male are pilose, thus approaching the genus Philedone.
