" In collecting the pupae of the genus Lithocolletis, 

 the portion of leaf containing the pupa requires to be 

 cut out, and the pupa (still in the mined portion of the 

 leaf) enclosed in a tightly corked bottle. In this man- 

 ner they may be kept the whole winter without drying 

 up, provided the bottle is kept constantly closed. (See 

 page 3.) 



"The extremely-interesting genus Coleopliora require, 

 in order to obtain success, open-air feeding. The plan 

 I adopt is the following: — I obtain several round tin 

 cases, about nine inches deep by five in diameter. I 

 then cut out the whole circumference of the lid to 

 within about half an inch of its edge (see page 4), 

 and procuring a piece of old calico or linen place it 

 flat over the mouth of the tin case. Then put on the 

 lid, pressing it down. This necessarily draws the 

 calico tight, and your Coleophora breeding-cage is 

 then complete. When wanted for use, put about two 

 inches of earth in the bottom of the tin. In the centre 

 of this put a small tumbler, or wide-mouthed bottle, 

 containing the food placed in water. Put the larvae 

 on the top of their food; cover them (as before ex- 

 plained). Put the whole out into the open air, in a 

 cool place, out of the reach of the sun, and you will 

 have no reason to complain of want of success, if they 

 are supplied with sufficient food. 



" Larva? that feed in the roots of plants require the 

 foot-plant to be replanted, either in the open ground 

 or in large garden pots, until the end of spring, when 

 they must be taken out of the ground, and placed, 

 with moist earth, in a deep breeding-cage ; or if planted
