The periodical cicada in WVa. . of the insect and was fortunate enough to find careful examination and comparsion with the eggs ofthree species of tree crickets, it was plain to me that they wereeggs of this class of insects, and that since the eggs werefound in the characteristic egg cavities, it was plain that one ortwo species of tree crickets are primarily to blame for the trou-ble referred to. It appears that the insect does not oviposit in rapidly grow-ing branches on young trees, but selects those which are mak-ing quite slow growth. Thus, when the wound is attendedwith blight, and is subsequently attacked by the woolly aphis,the wound seldom heals, and the exposed wood commence todecay, and the branch dies, breaks off, or becomes unproduc-tive. I shall endeavor to find out more about the habits and dis-tribution of the tree cricket that causes this trouble, and willbe greatly obliged for information from our readers in differentsections of the State, with reference to the presence or absence p ^ 2,. cr — — P CD ? c« t-3 cr ~~- o p o H ~ - tj1 .^ cd cd cd - p 3 p - ??* p P jq — - — O- 2 Q — — !z do «, i—• ST _. f) 1 - ?i ^ > -? ~ ^ - ? 73 s U? 3 2 M c nr = a; 3 o ?d 3 C P CD a u & 3 - KJ DD - O ?» CDIT. - (/; y „ Y p >? & - n CD n !> C CD _ < a ?fl -j- P =r c H_ ?-s i/j o - O o g *a li-ra T3 •< o O o -< r/i =r cd cd CD - ri 5! a — — a o <^ 1-3 CD no y o ^ 2_ 5 ~ fff a o 3 CKJ 3T|C ^ CD CD a a < -. o - — D Z p fi 5 -:
