stand 1 in. apart; the entrance is ■& by 12 in. next a space in the case of U by 2 by 

 14 in. A block 1 by 1 .} by 2 in. is placed between each hive, and the entrance to the 

 strip I by 2 in. by 13 ft. is nailed to the top of these blocks, thus forming 10 compart- 

 ments of IV by 2 by 14 in. The roof is of the -able sort and furnished with a lock. . 

 The tloor of the porticos slants so that dead bees and the rain fall away. 



A noiiswarming device (Amer. Bee Jour., 37 (1897), No. 16, p. 241, fig. I).— It is 

 stated that bees desiring to swarm may be controlled by placing two hives side by 

 side, each having a 6-ineh tin tube inserted in a hole bored in the lower side of the 

 middle of the front. When the entrance of one hive is closed the workers are obliged 

 to come out through the tin tube and, being unable to get back, go into the adjoin- 

 ing hive. After several days the entrance to the second hive may be closed and that 

 of the first one opened, which forces the bees back into the first hive again. The 

 method is said in no way to interfere seriously with the working of the bees, but it 

 effectually destroys the swarming fever and all <|iieen cells that may have been 

 formed are torn down. 



The San Jose scale in Missouri, J. M. Stedman (Missouri Sta. Circ. Inf. S, pp. 10, 

 fig S _ gy — \ brief popular account of the scale, with a recommendation of the usual 

 precautions and remedies. 



A report on the occurrence of the cabbage root maggot, F, A. Waugii ( Ver- 

 mont Sta. Bpt. 1896- 97, pp. 116-119, figs, l).— -It is briefly noted that cabbage, cauli- 

 flower, broccoli, and kale were found attacked by this insect (Phorbia brassicce). 

 There are a few comments on its distribution, method of feeding, life history, and 

 treatment. The use of kerosene emulsion about the roots of the affected plants is 

 recommended, as is also the preventive measure of placing tarred paper about the 

 stem of the plant at transplanting time, and especially that of avoiding planting in 

 gronnd where the insect has been at work the year before. 



A further communication relative to the grapevine beetle, K. Sa.to (IUks. 

 Wchn8chr. Ent., 3(1897), No. 9, pp. 129-134). — The question as to whether Eumolpua 

 obscurus has been found on the vine is discussed and affirmative evidence brought 

 forth. Topsenfs hypothesis that E. vitis and E. obscurus are one and the same, and 

 that the difference in color is due to the food plant from which each may chance to 

 be taken, is shown to be without the support of facts or even an investigation. 



The beech woolly louse, C. Schr'oeoer (Illus. Wchnschr. Ent., ? (1897), No. 15, pp. 

 225-229, fig. I) . — Schizoneura lanigera is discussed. A wash of 50 parts soap, 100 parts 

 amylalcohol, 200 of alcohol, and 650 of soft water is recommended.

The willow leaf beetles, ROrig (Illus. Ztschr. Ent, 2(1897),No.42,pp. 657-661).— 

 More or less of the life history of Chrysomela vulgatissima, Phratora vitelline, /'. cceru- 

 lescens, and Gabruca eaprew is discussed.
