SOME INSECTS OF THE YEAR IN GEORGIA, 81 



give the poison a thorough test, and a special trip to Vienna, Ga., 

 was taken for the purpose of making an experiment. Upon arrival, 

 however, the beetles had so far disappeared as to render poisoning 

 unnecessary. Further investigation showed that the beetles disap- 

 peared in two or three weeks as suddenly as they had formerly ap- 

 peared. For want of any accepted common name Ave have given this 

 beetle the name, " the new cotton beetle," for it is new to the cotton 

 growers of Georgia, and for a time it certainly looked as though the 

 damage caused by it might be serious. The ultimate injury was not 

 great, as the beetles did not spread far from where they first appeared. 



The cotton red spider (Tetranychus gloveri Bks.) appeared in sev- 

 eral cotton fields this year, sometimes covering 2 or 3 acres in a field. 

 Dusting with sulphur and spraying with kerosene emulsion was said 

 to give relief in some places. 



Among other cotton insects collected in Georgia this year may be 

 mentioned the sharpshooter (Oncometopia undata Fab.) and the cot- 

 ton leaf -bug (Calocoris rapidus Say) ; also Nezara hilaris Say and 

 the cotton aphis (Aphis gossypii Glover). None of the last four in- 

 sects mentioned have caused serious damage, although the cotton aphis 

 was abundant as usual. 



On July 24 a letter came to the office from Statesboro stating that 

 some worms had destroyed a 4-acre field of German millet. This 

 insect proved to be the fall army- worm (Laphygma frugiperda S. & 

 A.), as determined from one half -grown larva. Unfortunately, we 

 could not get specimens to rear, as the worms all disappeared within 

 a few days after the report. Our correspondent stated that the 

 English sparrows devoured thousands of them, though we believe 

 that they were then entering the ground to pupate. This same worm 

 was observed in a pear and plum orchard in Augusta feeding on the 

 crab grass. From larvse collected at this point adults were reared 

 September 9. 



The Hessian fly (Mayetiola destructor Say) is found in all the 

 wheat fields of Georgia. The spring brood appearing in many fields 

 last spring must have come mainly from the volunteer wheat, as 

 nearly all the wheat in the fall of 1904 came up so late — owing to 

 dry weather — that it was not then infested. Wheat planted early 

 this fall has been found infested to the extent of 96 per cent. Many 

 of our wheat growers are being brought to see the value of late plant- 

 ing and destruction of the volunteer wheat. 



Crambus pascuellus L. was reared from one larva collected from a 

 corn field near Atlanta. Apparently larvse of the same species were 

 collected from corn at Ringgold and Summerville, though we were 

 unsuccessful in rearing adults. This species, we understand from 

 Doctor Chittenden, has never been reported as feeding on corn before.
