The last of October, transfer the pupas to their winter quarters, taking 

 them from the ground, and placing them in flower pots, containing 

 ground as above prepared, and fine sand centrally, in which the pupse 

 are to be embedded, properly marking the contents of each. Prepare 

 a box of suitable size, with holes in the bottom for drainage, and a wire 

 cover, to exclude mice and other depredators. In the bottom of the 

 box put a few inches of coarse gravel, covered by a layer of earth, upon 

 which place the pots, and fill to the top with earth and dry leaves. 

 Bury the box six inches under ground, and over it, cover with boards, 

 to prevent water from entering the box. 



Early in May, remove them from their winter quarters to some soft 

 earth, arranging them so that the imago, when it emerges, may be re- 

 ferred to its pupa. Upon the earth lay a covering of wet moss, which, 

 by removing and saturating about once a week with water, will furnish 

 the necessary degree of moisture to the ground beneath. An excellent 

 location is an open verandah, out of the direct rays of the sun.

 reaching to the vascular line, (jaudal horn slender, .20 in. long, quite 

 rough with numerous acute granulations, which are more prominent 

 than those of the body.
