Brood X of the Periodical Cicada in Missouri. In Missouri Agricultural Experi- 

 ment Station Bulletin No. 137, "The Periodical Cicada in Missouri," the writer 

 published the records of distribution of Brood X Septendecim collected by Professor 

 Stedman in the summer of 1902. At the time of preparing the data for publication 

 the writer carefully went over the original records and included only those which 

 seemed without doubt to be accurate. 



This brood appeared again this year and a new set of records have been collected 

 and tabulated. The records for 1902 showed the i)est to hv quite generally distributed 

 over much of the eastern half of the state and in some localities in considerable abun- 

 dance. It will be of interest to know that if the records for 1902 were correct this 

 brood of the Cicada is rapidly disajjpearing in Missouri. The 1902 records showed 

 it to be present in thirty-two counties while in 1919 records received just after the 

 time of disappearance showed that Cicada-s appeared in only four counties. Cape 

 Girardeau, Hickory, Perry, Puloski and possibly Carter. The localities are widely 

 separated and in no case were the Cicadas abundant. Since early arrivals are known 

 to appear one year in advance of regular broods, it is quite possible that some of the 

 Cicadas observed this year may have been early arrivals of Brood XIX of the thir- 

 teen-year form, which appears over most of Missouri next year. Be this as it may 

 it is clearly evident tluit Brood X is of little consequence in Missouri.

Swarms of Cotton Worm Moths visit Missouri. Since 1911 the fall migration of 

 the cotton worm moth (Alahama argillacca Hbn.) has not attracted any special 

 attention in Mi.ssouri, but during the last of September and the first two weeks of 

 October the moths apjx^ared in great numbers in the state, doing some damage to 

 ripe fruit. During this visitation the moths were not nearly so abundant as in 1911 

 but around j)iles of decaying fruit, tomatoes, persimmons and other attractive bait 

 they have been observed to collect in swarms. In a moth trap set at Columbia on 

 the night of October 14, facing an orchard and vegetable plats, and at a distance of 

 one hundred yards from them only a few moths were caught, (^areful examination 

 on the following day showed that but few moths remained. 



It will be of interest to learn if this is another year of extensive northward migra- 

 tion of this queer moth, similar to the fall of 1911.
