Macrc-Lepidoptera in general. There are, however, a few- 

 exceptions, and these are what entomologists call internal 

 feeders. These live in and feed upon the boles and 

 branches of trees, stems of plants, &c.; and as wood is in 

 many instances their natural food, they cannot be expected 

 to refrain from eating their way through the sides of a box 

 or the lid which covers a pot. These are very diificult 

 to rear, and will again be spoken of. But whilst on the 

 subject of breeding-cages, confectioners' glass jars, with 

 glass covers, may be mentioned as useful and suitable for 

 them. As ft-esh air is necessary for the well-being of these 

 larv^, either the lids must not fit tightly, or, if stoppers 

 are used, holes must be drilled through the glass near the 

 top of each jar. 



Though preparations have been thus made for the 

 reception and safe custody of the caterpillars at home, the 

 entomologist is only half prepared. He has still to be 

 provided with means for ready capture and conveyance to 

 future quarters. His Avants, however, are few and simple, 

 and consist of a dark lanthorn to aid him in looking for 

 those larv^ which are difficult to find by day ; an umbrella 

 or large net to place under the bushes or branches of trees 

 whilst beating ; a stout walking-stick, a sandwich box, and 

 a few chip-boxes for the reception of the caterpillars. 



The new season commences with the new year, and 

 there is little to be done during the first two months. 

 Many moths spend this season in the ova state, 

 attached to webs, trunks of trees, twigs, blades of grass, 

 &c., sometimes singly and sometimes in numbers. In 

 some situations these are easily found, whilst in others 

 with such difficulty that they require patience, perseve- 

 rance, and a quick eye, to ensure success in finding them. 

 Valuable and rare insects are sometimes found in this 

 State ; and it is well to look for them, since many species 

 are most easily obtained by procuring their eggs.
