The spoiling of fruit at a temperature 



below 40° F. is due to 



moisture." — F. J. C. 



Colorado Beetle, The (Dorypliom {Lcptinotarsa) decemlineata, 

 Say.) By F. V. Theobald (Jour. Bd. Agr. vol. viii. No. 2, pp. 147-154, 



with a coloured plate). — This article gives an account of the recent 

 occurrence of this pest at Tilbury. " The infested plot was burnt with 

 parafiin and the ground soaked with the same, and then heavily dressed 

 with gas lime, which was deeply ploughed in. All the surrounding 

 herbage was cut and burnt, and also dressed with gas lime." And the 

 country for a radius of 3J miles was searched, without revealing a single 

 beetle. This information is followed by an account of the life-history of 

 the beetle, and is illustrated by a beautiful coloured plate by T. W. 

 Frohawk. A list of the food-plants is also given, including those upon 

 which the insects were found feeding at Tilbury. These included the 

 Woody Nightshade, Cabbage and Thistles, whilst the eggs were found in 

 one case on Sow Thistle (Sonckus). As to the possibilities of the insect 

 living in England, the author states that " although we have no member 

 of the genus Doryphora living in Europe, there seems no reason why 

 this particular species should not live and become perpetually established. 

 The climatic conditions of this country are by no means inimical to the 

 Colorado beetle. The insect, says Riley, is northern rather than southern 

 in its native habitat. The larvse, according to Riley, cannot withstand 

 any great variation in temperature ; they do not thrive, he says, where
