Twelve new varieties of the Tree Pceony. 333 



of June; and, during the present season, mostly between 

 the fitst and seventeenth, and none after the twentieth day 

 of the month. The grub closely resembles that of other 

 species of Saperda, and particularly the grub of the apple- 

 tree borer, or Saperda bivittata. The accompanying fig- 

 ures, 1 and 2, were drawn from specimens sent to the 

 writer by Dr. Swift. The first figure is from a grub of 

 larger size than usual. The second represents the insect 

 in the transition or pupa state, after it has done boring, and 

 has cast ofi' its grub-skin, previously to its final change to 

 a beetle. This pupa was dug out of the trunk of a linden, 

 in Philadeljihia, on the twenty-seventh of May. Figure 3 

 is from a very large and fine beetle, captured in Milton, 

 Massachusetts, more than twenty years ago. 



These figures and observations may serve to make the 

 insects better known, and, by directing attention to their 

 ravages, may lead to the discovery of more successful 

 means for arresting them.

Art. V. — Descriptions of twelve new Seedling varieties of

Agreeably to promise, I transmit you, annexed, the de-

 Moutan papaveracea, and var. Banksii, and rosea, the 

 most of which are remarkably splendid. I divided the 

 plants last March, and now have from three to six of each 

 variety. I have many seedlings that have not yet flow- 

 ered, and the single flowering ones among those which 

 have flowered, I rejected. This class of flowers was a very 

 favorite one with my deceased father, and both he and 

 myself have taken great pains in its extension, and the 

 new catalogue now in press will contain forty-two varie- 

 ties of the Mikdan and ninety herbaceous varieties, many 

 of which cost from ten to twenty dollars each for the im- 

 ported plants. I was fortunate enough to obtain one col-
