emerging from the ground it mates and begins feeding. For from 
four to six weeks after their appearance the beetles continue feeding, 
almost constantly paired. The female deposits her eggs singly, from 
24 to 36 in number, a few inches beneath the surface of the earth, 
where in from two to three weeks they hatch and the young larve 
or grubs begin feeding on such tender rootlets, preferably of grass, as 
are in reach. By autumn the larve, which are yellowish white in 
color, with pale-brown heads, have reached full growth and present 
the appearance shown in figure 1 at 6. Late in autumn they descend

lower into the earth, below the frost line, each grub forming a little 
earthen cell in which it passes the winter. In April or early in May 
they transform to pup, and in from two to four weeks afterwards 
the beetles emerge, dig their way out of the ground, and renew their 
destructive work. <A single generation of the species is produced in 
a year, and about three weeks is the average duration of life for an 
individual adult. 
METHODS OF CONTROL. 
The rose-chafer is one of our most difficult insect enemies to com- 
bat successfully. Almost every appropriate method that has ever 
been employed against other insects has been tried against this one, 
and much has been written on this insect, but a thoroughly effective 
remedy is yet to be discovered when the insects appear in excessive
