ECONOMIC ZOOLOGY — ENTOMOLOGY. 259 



The author finds that in Maine there is but one generation or at most only a 

 partial second generation. In 1912 the first eggs were observed on June 26 

 and none were found later than the middle of July. " On July 30 full-grown 

 larvffi and a few pupae were found among the roots of these plants, the larvre 

 mining in the seed potato, the body over half buried within the tuber, the 

 posterior end sticking out at right angles to the surface. The pupae as well 

 as some of the larvae were found free in the earth among the roots. . . . Dur- 

 ing August, 1912, larvfe and pupae were to be found in the ground among the 

 young tubers but by the end of the first week in September they had all disap- 

 peared. About the middle of July the beetles of this generation begin to emerge 

 in Maine, becoming very abundant upon the potato vines and reaching a maxi- 

 mum about the first of September. The first killing frost in September marks 

 the disapi^earance of the beetles to their places of hibernation." 



It is pointed out that this beetle, which is often called the cucumber flea 

 beetle because it was originally described as feeding on the cucumber, feeds by 

 preference upon plants of the family Solanacece which includes the potato and 

 the tomato. A test of the susceptibility of various plants to the attack of this 

 insect is briefly reported. 



In spraying experiments with arsenate of lead and with a combination of 

 Bordeaux mixture and arsenate of lead, both with and without corn sirup at 

 the rate of 2i qt. of sirup to 50 gal. of spray mixture, in which the applica- 

 tions were made every 2 weeks during the season, there was decidedly more 

 rtea-beetle injury in the unsprayed check plats than in the sprayed, and the 

 least injury in the plats sprayed with a mixture containing Bordeaux. There 

 was no noticeable difference between the plats which were sprayed with the 

 mixture containing sirup and the corresponding one without it. In laboratory 

 experiments, however, the addition of sirup to the arsenical used aided in de- 

 stroying the beetles. 



A bibliography, arranged alphabetically by authors, is appended to the paper. 



A list of insects recorded on potato, arranged alphabetically by orders, by 

 Edith M. Patch (pp. 51-56) concludes the bulletin.

The control of the alfalfa weevil, E. G. Titus (Utah Sta. Ore. 10, pp. 105- 

 120, figs. 15). — This is a brief account of the alfalfa weevil, its present dis- 

 tribution, and the principal methods that appear to be of value in its control. 



During the years 1911-12 the weevil spread over many miles of territory, 

 both north, south, and southeast, so that its present distribution includes Weber, 

 Morgan, Davis, Salt Lake, and Utah counties in Utah, and parts of Uinta 

 County, Wyo. ; Bear Lake and Oneida counties, Idaho; and Box Elder, Cache, 

 Rich, Summit, Wasatch, Sanpete, Millard, Juab, and Tooele counties, Utah. 

 Thus far the author has found no mountain range in Utah that appeared to 

 obstruct in any way the movement of the weevils. Weevils have been taken as 

 high as 9,500 ft. in Salt Lake County, where they had apparently been carried 

 partly by winds when they were flying. Among the remedial measures recom- 

 mended are late disking or spring-toothing in order to keep the alfalfa growing 

 rapidly in the spring; removal of the first crop as soon as serious injury 

 occurs, followed immediately by a thorough use of the spring tooth and brush 

 drag; rotation of alfalfa at least every 4 or 5 years; and the cleaning up all 

 around the farm, especially canals, ditch banks, weed patches, gardens, etc.
