probabh^ true. The beetles, like the rose chafer, were seen in copu- 

 lation at any hour during the day. Subsequent observations showed 

 that these beetles also occurred in abundance on sycamore and that 

 they even relished the acrid foliage on black walnut. 



The beetles also resembled the rose chafer in their sudden appear- 

 ance, their time of activity (about one month), and their ec^ually sud- 

 den disappearance at the end of that time. 



Anomala minuta Burm.^ — The black form of this species was received 

 May 2, 1901, from Mr. B. H. Frazier, Fruitdale, Ala., where it was 

 observed working on young peach and plum trees set out that spring. 

 The beetles burrowed in the ground around the trees to a depth of 

 1 to 3 inches into the moist earth. They ate only the j'oung, 

 tender leaves. It was also noticed that the}' seemed to be most 

 numerous in the drier and sandier soil of that vicinity, which suggests 

 that the larvae probably fed on grasses grown in such locations. 



While writing of the habits of these vine chafers it may be well to 

 add that on one occasion A. undulata was observed affecting growing 

 wheat, in another case attacking petunias, and in still another affect- 

 ing- grape. A. marginata is most commonly found on the vine, as is 

 also niinuta. A. Incicola is also a grape-feeding species, and IjuKdata 

 has been found on the grape as well as on strawberry and locust. 



Heinedies. — In the treatment of these vine chafers we have prac- 

 tically the same problem, in many cases, as in dealing with the rose 

 chafer. The beetles f requentlj' occur in such numbers and devour the 

 leaves of young and tender fruit trees so rapidly that Paris green 

 does not produce the desired effects. In ordinary cases, however, an 

 arsenical spray is sufficient for their destruction. Dr. Harding has 

 met with good success both with spraying and with shaking the beetles 

 off and burning them, in much the same manner as described in con- 

 nection with the blister beetles which affect fruit trees. — F. H. C. 



THE COLORADO' POTATO BEETLE IN THE SOUTH. 



We have recently received information from manv correspondents 

 in Southern localities furnishing evidence that the Colorado potato 

 beetle {Doryphora 10-lineata Say) has lieen making a general effort to 

 extend its range southw^ard. Such migration has been noticed for a 

 number of ^^ears past, but has never been so noticeable as during the 

 season of 1901. The species will doubtless continue to spread south- 

 ward until it is overcome by natural enemies or perhaps killed out b}' 

 the weather. It has been noticed that this species has been destroyed 

 in great numbers during severe dr}- spells, such as was experienced 

 during the summer of 1900, the larvae being literally dried up on their 

 food plants. 



Our first information in regard to recent spread by this species was 

 from Mr. N. L. Willet, of Augusta. Ga. For the first time in his 

 remem))rance, that section was being devastated. He wrote. May 12,
