Plate XII, and the female may be distinguished from it by her 

 simple antennae and larger body. 



The caterpillar is coloured with alternate bands of dark purple 

 brown and reddish brown. There is a yellow band on the front of 

 the second segment, a row of yellow spots on each side, and two 

 little bright yellow warts on the back of each segment. It feeds by 

 night on lime {Tilia vulgaris), elna (Ulmiis cawpestris), and 

 various fruit trees, and often appears in such numbers that the 

 foliage is almost completely devom'ed. During the daytime it may 

 be seen resting on the bark, almost invariably fixed longitudinally 

 on the trunk, where it looks like a natural ridge of the bark which 

 it so closely resembles in colour. It may be found in June and 

 July, and in August it changes to a chrysalis at the foot of its tree, 

 just below the surface of the soil.

 projections, of which there is one on each side of the fifth, sixth, 

 seventh, eighth, tenth, and eleventh segments; also two on the 

 back of the ninth and twelfth. It feeds in August and September 

 on a large niimber of trees, including, in fact, nearly all our com- 

 monest forest and fruit trees. In Sei^tember it enters the soil to 

 undergo its change to the chrysalis.

In the next family — BoarDiiidce — there are aliout twenty Eritisli
