Scientific Notes 



Cotton Moth {Alabama argillacea Hubn.). The moths were observed in Kent, 

 Ohio, in large numbers September 23, 1914, following several days of warm weather 

 with a strong south wind. This weather condition was produced by a high area that 

 hung over the central Atlantic coast for some time, causing the storms to be deflected 

 to the north through Canada instead of following their usual course. The moths 

 were so abimdant on this date, the time of their initial appearance for the season, as 

 to almost cover portions of telegraph poles upon which they were resting. 



Smaller flights were observed on two or three other nights though the dates were 

 not recorded except that for October 16, a time when wea,ther conditions were similar 

 to those described for September 23. On each of the other occasions, the moths ap- 

 peared after a period of south winds. 



The flight at Kent, Ohio, was nowhere near as abundant as one observed at Bata- 

 via, X. Y., during the fall of 1912 and indu-ectly recorded through an article pubhshed 

 in the local paper. R. W. Bil^ucher. 



The Cabbage Curculio {Ceutorhynchus rapce Gyll.) Injuring Radishes. During 

 the last two weeks of April a number of reports reached the department of entomology 

 of a small snout beetle seriously injiu-ing radishes. Several of the inquiries were 

 accompanied by the insects. On other occasions the injm-y was investigated by men 

 of the department. In most of the instances it proved to be the cabbage curcuho 

 {Ceutorhynchus rapce). On some occasions as many as a dozen beetles were found 

 around the stem of a single plant, and in several cases they were found feeding on the 

 root an inch beneath the surface of the soil. The beetles were taken in several gar- 

 dens from iManhattan on east as far as Kansas City. They were also found at Atch- 

 son, Kansas. In many cases the early radishes were completely destroyed.

Radishes Seriously Injured by Flea Beetles. Over a considerable portion of 

 the eastern third of Kansas, the early radishes were very seriously injured by the 

 striped tiunip flea-beetle {Phyllotreta vittata Fab.) and the western cabbage flea- 

 beetle {Phyllotreta pusilla Horn). In many instances they appeared in unusually 

 large numbers and the radishes were entirely destroyed within one or two days. In 

 most cases the turnip flea-beetle was more abundant than the other. The work of 

 both species was confined principally to the succulent stem just at the surface of the 

 ground, causing the leaves to dry up and die. In some cases they also fed on the 

 leaves, especially where the plants were an inch or more in height. Some of the 

 truck growers report that the second and even the third plantings were destroyed.
