destruction have been devised. The young 

 larvae are easily found by the holes they make 

 in the leaves, and the surest method is to 

 press these with the fingers and kill them. 

 The application of powdered hellebore is the 

 next best mode. If not eradicated, they will 

 utterly ruin the fruit, as the berries do not 

 ripen properly, when the foliage has been 

 destroyed. 



My next two examples belong to a distinct 

 division of the sawflies sufficiently indicated 

 by the knobs which terminate their antennae. 

 Except among butterflies and sawflies this 

 formation is very rare. Undoubtedly it 

 implies an important structural difference, 

 but, as we do not know the true functions 

 of the antennae, we are unable to state 

 with certainty what the difference may be. 

 Cimbex femorata (Plate XII., Fig. 6) is a 

 large insect, nine lines in length, black, with 

 a black or brownish pile, and wings clear save 

 for a blotch upon each forewing. It may 

 be met with in woods during June or July. 

 At the same season we may find Abia fasciata 

 (Plate XII., Fig. 7), a brassy-black fly, 5 lines 

 in length, its abdomen smooth and shining,
