Velleda Lappet Moth. 

 (Tolype velleda.) 



The larva of this insect is remarkable for having on each side 

 of each segment a little lappet or flat lobe; from these many 

 long hairs are given out, forming a fringe to the body. It is 

 bluish gray, with many faint longitudinal lines ; and across the 

 back of the last thoracic segment there is a narrow velvety 

 black band. When at rest the body of the larva is flattened, 

 and the fringes on the sides are closely applied to the surface 

 of the limb. The larva is full grown during July. The cocoon 

 is brownish gray, and is usually attached to a branch of the 

 tree. The body of the moth is milk white with a large black- 

 ish spot on the middle of its back, the wings are a soft bluish 

 gray crossed by white lines. The moths have an expanse of 

 wing ranging from i| to 2 inches. 



remedial measures. 



It is rarely necessary to apply repressive measures. Arseni- 

 cal sprays will control these insects, if abundant enough to 

 prove troublesome. 



Rose-Chafer. 



{Macrodactylus subspinosus Fab.) 



" The rose-chafer (fig. 18), a long-legged beetle of a light yel- 

 lowish brown color, and about a third of an inch in length, 

 appears in June, the date varying somewhat according to local- 

 ity and season, and the beetles mate and begin feeding soon 

 after they emerge from the ground. For from four to six 

 weeks after their appearance they continue feeding, almost con- 

 stantly paired. The female deposits her eggs singly, from 

 twenty-four to thirty-six in number, a few inches beneath the 

 surface of the earth, and in about two or three weeks' time 

 they hatch and the young larvae or grubs begin feeding on such 

 tender rootlets, preferably of grass, as are in reach. In autumn 

 they have reached maturity. They are yellowish white in color, 

 with a pale brown head. Late in autumn they descend lower 

 into the earth, beyond the reach of frost, and in early spring 

 they ascend, and each grub forms a little earthen cell in which
