The former comprises the first five tribes, namely, 

 the Rhojjalocera or Butterflies, the Sphinges, the Bomhyces, 

 Noctuce, and Geometrce. Though some of the species 

 included in these are small, the majority are large. 



The latter section comprises the Pyrales, CramhinoB, 

 Tortrices, Tineince, and PteroplwridcB. In these tribes a 

 few of the species are moderately large, but the majority 

 are small. 



To go out and collect a number of larvae, without pre- 

 viously providing suitable places for them at home, would 

 be folly ; a few remarks aboiit breeding-cages will, there- 

 fore, not be out of place. 



A large box, measuring half a yard or two feet square, 

 ■will be very useful ; especially for those insects wliich 

 spin cocoons or webs, and for such as remain only a 

 short time in pupae. The box should be constructed on 

 the plan of a meat-safe, the sides and top being of fine 

 wire gauze, nailed tightly on a frame-work of wood. It 

 is immaterial whether the top or a side be the doorway, 

 provided a full vicAV of the whole interior can be obtained. 

 Moss should be placed in the bottom, to the depth of 

 several inches, for the caterpillars to bury themselves in 

 when about to become pupae ; and there should also be a 

 fair quantity of ledges and corners throughout the box, 

 to form asylums for the Aveb-spinners and others which 

 do not bury. The wooden bottom of the cage absorbs 

 much of the moisture from the moss, whilst there is a con- 

 stant drainage from the surface by means of evaporation 

 through the wire gauze on the sides and top ; hence, a 

 dryness ensues which is very prejudicial both to larvae 

 and pupaj. This must be obviated by frequent waterings. 

 On the other hand, too much moisture is eqiuilly injurious 

 and care should be taken to preserve a medium. Should 

 the box be allowed frequently to become quite dry, 

 waterings cause it to grow mouldy, and the insects die ;
