" We keep a book in which is entered a description of the larva to be drawn ; to 

 this a numeral is attached : the larva is placed in a case, and on this, as well as on 

 the drawing, the same number is marked. We then patiently await the arrival of the 

 imago, to verify the name of the larva. 



" In prosecuting our work, no name is affixed to our list until we are certain of the 

 insect by its appearance in the breeding-cage. It is this great anxiety to verify, by 

 actual fact, every insect that we find or is sent to us, that causes such an infinity of 

 trouble ; for it is painful, from one cause or another, to find how often our hopes are 

 baffled by the untimely death of the larva or pupa, and then another year or two must 

 pass away before we may obtain specimens again. Thus we have now considerably 

 more than a hundred drawings unnamed, and consequently unregistered in the 

 finished series. 



" In breeding larvas, some feed only at night, others in the direct sun-light, others 

 at any time : care must be taken to favour each peculiar habit ; if not, failure will 

 ensue. Also, some bury themselves in the earth, either to hide or to change into 

 the pupa state, others spin a cocoon on a branch, others on the surface, collecting 

 the loose material around; in every case the insect ought to have the means of 

 following its natural instinct. Thus, peat or broken turf and white sand make a good 

 soil for the larvae to retire into ; this ought to be covered with close clean moss, free 

 from insects, and kept moderately damp, and with a few upright pieces of wood for 

 the insect to stretch itself upon after feeding, as we observe it is the habit of the 

 nocturnal feeders to lie at full length for a short time after their evening diet.
