one end of the table to the other, waving its antennae in great 

 excitement. 



Brood females travel well by post in these G.T.B. A culm of 

 green wheat or coarse grass to which they can cling is curled round 

 in the box, and if they can be induced to feed before they start, so 

 much the better. It is important that no green stuff that will become 

 flabby should be put in the box. It flaps about and makes the 

 insect so restless that the chances are it will arrive with broken wings 

 and legs, and so reduce the chance of getting ova. I have had some 

 cardboard cases made to take these boxes. They cost 5.^. per 

 gross, and as they can be used without paper, the string is supplied, 

 and the boxes are not smashed, they must be considered very cheap. 

 I do not know how long the butterflies will live in these G.T.B. , but 

 last autumn I kept a Pieris rapce for eight days without food in 

 one of them, and afterwards obtained ova from her. 



Newly hatched larvae (except Satyridee) I keep indoors, and for 

 their management keep within reach of my table the following 

 apparatus : — A drawing board covered with cartridge-paper, an 

 enamelled iron basin, a tin of dry sand, a lump of cotton wool, a box 

 of rubber bands, bottle cages with spare covers, and G.T.B., together 

 with scissors, forceps, brushes, and a teaspoon. 



When the larvae make their appearance, if butterflies (except 

 Satyridae) or Geometers, I transfer them to bottle cages, making a 

 careful note of the number hatching from day to day. Extreme care 

 must be taken not to put too much food in the cage, or the moisture 

 condensing on the glass will drown your larvae, and not to put too 

 many larvae in one cage. A small quantity of food keeps admirably 

 in these bottles by snipping the ends of the stems and exposing a 

 fresh surface, and changing the water in the gallipots. Some plants 

 may be kept fresh till devoured to the very last atom by the larvae, a 

 no small advantage when the amount of time and handling is con- 

 sidered. For some Noctua^ and Bombyces in their earlier larval 

 instars I have used G.T.B. with some success. Noctua, Tsniocampa, 

 and Hadena do admirably in them ; they require, however, by this 

 treatment daily attention. The plan I adopt is to put fresh food in 

 on the top of the old every morning, and remove the old and rub the 

 box clean and bright every evening. This is not so much trouble 

 as it looks, provided too much food is not put in. The food to 

 which the larvre will be clinging is gently lifted out with the forceps, 

 the box cleansed with a stiff paint brush and duster, new food re- 

 placed, and stray larvte rapidly put in by means of a teaspoon and 

 camel's-hair brush. Great care is to be taken that these boxes are 

 never exposed to the sun, or disaster will follow. 



As soon as the larvae are big enough they are transferred to larva 

 cages in the garden. The cages are in a larva house, which I will 

 describe ; I designed it many years ago, and have from time to time 

 altered it. It much resembles a shelter for meteorological instru- 

 ments. The back and two ends are louvred shutters, the front three
