or, freckled with numerous black dots and clothed with short, blackish and fox-colored 

 hairs. The second segment or neck is edged anteriorly with cream white, which color is 

 more broad upon the sides. The third and fourth segments have each a large, black spot 

 ■on each side. The instant it is immersed in spirits, the blue of this Caterpillar vanishes, 

 and it becomes black." 



A good representation, except the natural colors, is given of it in the engraving. 



The Cocook and Pnr^. — The cocoon is composed of silken threads loosely woven 

 on the outside and intermixed with the hairs of the larvse, more densely woven on the 

 inside ; color white, but is filled with a paste from the mouth of the larvse, which when 

 dry gives it the appearance of being sprinkled with sulphur. It is about 1.30 of an inch 

 long and 0.43 wide. This cocoon contains the chrysalis (pupae) which is of a reddish 

 brown color, slightly dusted with pale powder, and is densely covered with short, pale, 

 yellow hairs, which hairs are longer and darker at the blunt and rounded end. 



The Moth. — (Perpect Imago.) — At 6 in the engraving is represented the Moth of 

 the Tent Caterpillar of the forest (Clisiocampa Sylvntica, Harris,) of natural 

 size. It measures about two inches from tip to tip of its wiugs. Its body is 0.90 of an 

 inch long and 0.30 of an inch across the thorax. Color brownish-yellow or rusty-brown, 

 with two oblique, transverse lines across the front wings. Some specimens are, however, 

 more pale or yellow. The color between the lines on the wings is darker than on either 

 side. This is one particular distinguishing feature in this Moth, as the space in the Tent 

 Caterpillar of the orchard is lighter between these lines. In the Tent Caterpillar of the 

 forest the transverse shade often extends across the lateral wings of the Moth, 

 faintly. 



Remedies. — During the winter and spring, when the trees are bare of leaves, the egg 

 bands are easily discovered, and should never be passed by, but removed and destroyed. 

 There are several natural foes to the Tent Caterpillar of the forest, the large Gourd 

 Beetle {Colosoma Scrvtator, Pabe.) and parasites belonging to the orders Exorista and 

 Pimpla prey on them in the larvae stijte, and do much to keep them in cheek. 



COmmON TWIC BORE:R.—(Bo8trlcn8 Blcandatus, of Say.) 



By the Entomological Editor. 

 These insects our correspondent doubtlessly found in holes in his vines, where they 

 had bored down the center of the small branches, about the size of a common lead pencil- 

 They entered the vines at the axil of a bud. Two years ago we saw them in the vines of 

 Mr. H. Dorsey, of this place, (Clarinda, Iowa,) doing the same kind of mischief Lastfall 

 a correspondent from Yankton, Dakotah, sent us a few specimens, and complained of 

 their disastrous work in his apple nursery trees. For years they have been known to 

 work among the twigs of large apple trees, and hence have not until recently been 

 regarded as very injurious, because the small twigs they usually bored were during the 

 summer broken ofl' without much injury to the trees, thus amounting only to eummer 

 pruners. But now that they attack grape vines and nursery stock in the body of young 

 apple trees, we fear they are to be feared more than heretofore. In Volume two, Number 

 eleven, of the Pomologist, we published as much of their natural history as is known, 

 and a cut, which we repeat in the mr.rgin of this article, which will 

 serve to give the reader an idea of this insect. It is supposed that this 

 insect breeds in the sap-wood of forest trees. Its natural habits in this 

 respect are unknown to entomologists. The only way we know of 

 fighting them is to cut oflf the infested wood and burn it and the insects 

 together.

Ed. Pomologist and Gardener. The term "moth-proof" applied to a bee-hive, is a 

 misnomer ; for it is impossible to construct a hive that will admit the bees, and exclude
