THE SUBSTITUTE. 
223 
You will fail, they are so varied ; 
Some are hnohbed, and some are threadlike, 
Some are forked, and some are fanlike: 
All have four wings, clear and glittering, 
And a thick and iieshy body. 
Uniform throughout in thickness. 
Not nipped in and spindle-waisted, 
Like a wasp or like a spider : 
They have all the feet tive-jointed. 
Fore shanks, two-spurred at the summit; 
One sex only bears a weapon 
Near the tail, beneath the body. 
Sharply notched and very saw-like. 
And with this she quickly pierces 
A young leaf or juicy sucker. 
And her eggs sedately places 
In the wound she has created; 
From this saw we call them sawflies, 
Sawflies or Tenth redinina. 
Next a tribe with footless larvae. 
White, and fat, and stupid maggots. 
On the solid timber feeding. 
Burrowing deep into its substance. 
Leaving galleries behind them : 
They have long and thin antennae. 
Gently tapering to the summit. 
Wings transparent, and loud humming. 
Fore shanks one-spurred at the summit. 
And the feet are all tive-jointed ; 
Body uniformly rounded. 
Not nipped in and slender-waisted. 
And the tail is like an augur. 
Formed for boring into timber; 
If you ask me wherefore boring. 
What its use and what its object, 
I should quickly give this reason, 
That the fly may safe deposit 
Eggs in every excavation. 
Eggs from which the infant larvae 
Soon emerging bore still deeper. 
Deeper still into the timber : 
Let us call them Sieicina. 
All the oakapples and inkgalls. 
All the cherrygalls ond nutgalls. 
All the bitter Dead Sea apples. 
All the beautiful oakspangles.
