Fig. 15. 



The moth, Fig. 15, measures, when its wings are spread, fi'om four to five inches 

 across. The wings are of a delicate green colour, thickly covered with pale hairs as they 

 approach the body. There is a purplish brown stripe along the front margin of the fore 

 wings, which stretches across the thorax, while a small branch of the same is extended 

 to the eye-spot near the middle of the wing. The eye-spots are transparent in the middle, 

 and margined with rings of white, yellow, blue and black ; the hinder edges of the wings 

 are bordered with purplish brown ; the head is white ; the antennae feathered ; the 

 thorax thickly clothed with whitish wooly down, and the legs purplish brown. 



The Lime-tree Measuring Worm — Hybernia tiliaria. 



The larva of this insect is a yellowish looper or measuring worm, with a reddish 

 head and ten wavy black lines along the back. It is shown in Fig. 1 6 in different posi- 

 tions. It is hatched early in the spring, and completes its growth about the middle of 

 June, about which time it is often very destructive to basswood, elm, hickory and apple 

 trees. When ready for its next change, the larva lets itself down from the tree by a 

 silken thread, and buries itself five or six inches below the surface of the ground, and 

 there changes to a chrysalis, from which the moth usually escapes the following spring, 

 and occasionally some of the moths appear in October or November, but this rarely 

 occurs with us. 



The male moths have large and delicate wings and feathered antennje, as seen in the 

 figure. The fore wings, which measure, when spread, about an inch and a half across, 

 are of a rusty buff colour, sprinkled with brownish dots, with two transverse wavy brown 

 lines and a central brown dot. The hind wings are pale, with a brown dot about their 

 middle. 



The female, also shown in the figure, is a wingless, spider-like creature, with slender 

 thread-like antennae, yellowish-white body, sprinkled on the sides with black dots, and
