Euphoria melancholica Gory and Euphoria sepulchralis Fab. were 

 found eating into cotton bolls, probably after the latter became 

 injured by the anthracnose disease. 



Pissodes strobi Peck and Aramigus fulleri Horn were collected in 

 cotton fields, both being mistaken for the boll weevil by the farmers 

 who collected them. 



Carpophilus dimidiatus Fab. was frequently found in rotting cot- 

 ton bolls, and Conotelus obscurus Er. was discovered feeding in a 

 cotton bloom, evidently having emerged from a rotting cotton boll. 



GRAIN AND GRASS INSECTS. 



Mayetiola destructor Say, the Hessian fly, seems to have been less 

 abundant than usual in the wheat fields. This condition is due! 

 largely to the fact that heavy and continuous rains prevented the 

 sowing of wheat early in October, when the first fields are usually 

 sown. Our observations show that wheat sown after October 15 is 

 comparatively free from the fly in ordinary seasons. Volunteer wheat 

 which came up during the past August and September was in nearly 

 all cases found badly infested. 



The joint worm (Isosoma tritici Riley) is present in wheat and cer- 

 tain grasses, but has not been studied in Georgia. 



Sitotroga cerealella Oliv. was found in stored wheat at Austell, Ga. 

 An interesting occurrence in connection with this record is that prac- 

 tically all the grain moths were killed by the parasite Pedicidoides 

 ventricosus Newp., which was found in countless numbers on the 

 wheat and on the floor of the building where the grain was stored. 

 A complaint came to us that some insect of almost microscopic size: 

 was very annoying to the persons who had the handling of the wheat. 

 Upon investigation the trouble was found to be due to the parasite 

 just mentioned. The grain moth was found also at Cornelia infest- 

 ing stored corn. 



Laphygma frugiperda S. and A., the fall army worm, was perhaps 

 the insect that caused the greatest popular alarm in Georgia during 

 1906. On July 18 we investigated damage to corn at Cartersville, 

 Bartow County, and found it to be the work of this army worm. 

 The cornstalks were frequently eaten into in a manner resembling the 

 work of the corn stalk-borer (Diatrwa saccharalis Fab.). In fact, 

 when we first received a report by letter we supposed the trouble must 

 be caused by the latter insect. Young corn about knee-high was 

 eaten down almost completely, and larger corn damaged severely. 

 It was learned that the worms first appeared in a grass field, from 

 which they migrated to the corn. One field of cotton near Carters- 

 ville was damaged slightly. This army worm was next reported on 

 August 4, from Pinehurst, Dooly County, where it was devouring
