The " merry month of May " is the great month for larva beating. Now 

 is the time when most of the species which have hibernated are nearly, if not 

 quite, full-fed. These, therefore, are gladly seized upon, as they require but 

 little attention to bring them into healthy pupae. Of course in all these 

 cases it is desirable, if possible, to identify the species, and give it its proper 

 pabulum, and as nearly natural conditions as possible, to enable it to easily 

 pass into the next stage. Quiet and cleanliness are essential conditions of 

 healthy larval and pupal life, Breeding cages should, therefore, never be 

 crowded either with species or with the food-plant ; and should, if possible, 

 have some quiet crannies, with the requisite material, and space for each 

 particular species to effect its last and most important transformations. In
