getting rid of this pest. Negative results were obtained with fish 

 brine and with a 5 per cent, solution of birch-tar in boiling water. 

 Tobacco extract gave good results, but requires much time for its 

 preparation and repeated application. Quick-lime, although des- 

 troying a great many of the ants, does not prevent them from returning, 

 and a solution of 10 lb. of salt in 27 gallons of boiUng water had still 

 less effect, besides being injurious to plants.

The restricted use of carbohc emulsion in controlling aphids and other 

 insect pests is attributed to the frequent scorching of leaves caused by 

 it. These unfavourable results are due to variations in the strength 

 of the black, crude carbohc acid usually on sale, which varies from 

 50 per cent, to 70 per cent. In order to safeguard against this, the 

 solution should be tested before applying it, and the recipe given by 

 American authors (2| lb. of black crude carbohc acid and 3 lb. of 

 potash soap in 67-70 gallons of water) corrected, so as to arrive 

 at a solution which will destroy the pests and yet be harmless to plants. 

 The author always obtained good results with this insecticide against 

 Aphids, the caterpillar and imagines of Pieris brassicae, L., the cater- 

 pillars of Malacosoma neustria and the young nymphs of Psylla rnali. 

 Its use on roses exposed to sun is not recommended, as it may cause 

 scorching, quassia being preferable for this purpose. Rags soaked 

 with crude carbolic acid, renewed every two or three days, and hung on 

 sticks drive off various insect pests.

Hypera {Phytonomus) postica, Gyll., (the alfalfa weevil) is a native 

 of Europe, but does not do serious damage there as it is presumably held 

 in check by its natural enemies. How the beetle was first introduced 

 into the United States is not known, but it was first discovered in 

 Utah, where it now is a pest ; it also occurs in Wyoming and in 

 southern Idaho, but has not yet been found in the state of Washington, 

 where lucerne growers have frequently become alarmed at the appear- 

 ance of other and harmless beetles which they have mistaken for this 

 insect. This bulletin, which gives a popular description and hfe- 

 history of this weevil [see this Review, Ser. A, ii, 294], is published with 

 the object of aiding farmers to distinguish between these insects.
