as well as dried plants. The best remedy is said to be bisulphid of 

 carbon in closed boxes. A brief description of the different stages of 

 the insect is given. 



The tobacco-leaf miner (Gelechia picipel is). — The larva of this moth 

 injures tobacco leaves by mining or eating out patches of the leaf sub- 

 stance, thus rendering the leaves unfit (or wrappers. The life cycle of 

 the insect is said to require not longer than 20 days, which makes it 

 possible that several broods should occur in one season. The insect 

 may be kept in check by spraying with Paris green in the manner rec- 

 ommended for the tobacco worms. 



Cutworms. — Under this head brief notes are given on the cutworms 

 in the State, with special reference to the species Agrotis ypsilon. The 

 treatment recommended for cutworms is the use of bran poisoned with 

 Paris green, in which the Paris green is used at the rate of 1 lb. to 

 every 50 to 75 lbs. of bran. 



Grasshoppers or locusts. — Two species of grasshoppers are said to be 

 injurious to tobacco, Tezzoteitix femur-rubrum and P. birittatus. Paris 

 green is recommended for controlling these insects. 



Bud worms (Heliothis sp.). — The common bollworm of cotton (H. 

 armigera) causes considerable damage to tobacco. The eggs are depos- 

 ited in the buds and the larva' when hatched feed upon the young 

 unfolding leaves. The remedy which has been found to be effective is 

 the sprinkling of poisoned cornmeal into the bud of the tobacco plant. 



The chinch bug, F. M. Webster ( TJ. S. Dept. Agr., Division of 

 Entomology Bui. 15, n. ser., pp. 82, Jigs. 19). — The chinch bug is 

 recorded as being distributed from St. Vincent and Granada, West 

 Indies, into Lower California, on the west coast, to Cape Breton, on the 

 east. It covers pretty largely the whole eastern portion of the United 

 States as far west as Colorado and New Mexico. West of this line it 

 is found only in isolated areas in California. The author maintains 

 that the evidence which he has collected shows that the chinch bug 

 hibernates only in the adult stage. Pupa* and undeveloped larval 

 forms are found in late fall, but there is no evidence that these pass 

 the winter. A favorite place of hibernation of the chinch bug is said 

 to be in stools of the various grasses. Along the Atlantic coast chinch 

 bugs may be found in the spring in great numbers in the stools of sev- 

 eral maritime grasses, and in the interior the insects hibernate prefer- 

 ably in the matted blue grass, stools of timothy, and even under sticks 

 and rubbish. Ordinarily about three migrations of the chinch bug 

 may be observed annually— one in May, when the adults which have 

 wintered over move away to new feeding grounds, one in midsummer, 

 and one in the fall, during the so called Indian summer. These latter 

 two hibernations, however, are said to depend upon the food supply, 

 and if the food is abundant they are not observed to take place. 



The eggs of the insect are said to be deposited " either about or 

 below the surface of the ground, among the roots of the grass or 

 grain." Ordinarily the female deposits about 500 eggs during a period
