The following letter to the Imperial Comiuissioaer of Agriculture for the West Indies has been received from Mr. T. Jackson, the Curator of the Botanic Station, An'igna, transm tting cotton stainers supposed to have been killed by a funj5us- This is of general interest: — 'I am forwarding to )0U under separate cover some dead cotton stainers. These were obtained from under a mahoe tree growing in the Botanic Station. The tree in question had very many insects some w eks ago, but although young stainers are still somewhit abundant on it, there aro only a limited number of adults. 'A number of the insects s' nt are covered with mycelium which, possibly has been the cause of death. As many dead insects (adults and half grown) are to be found under the tree in question, it would seem a? though this fungus or some other control, is at present keeping the pest in check.' The fungus has been identified by Mr. W. Nowell, Mycolo- gist on the stafif of the Imperial Department, as Sfiorotrichum glohuliferum, a parasitic fungus on insects of wide distri- bution. It has been found attacking thrips of cacao in St. Vincent and Grenada, as was noticed in the Agricultural Newf, Vol. XV, p. 430. and it is also well known as an important natural enemy of the chinch bug in Kansas and other localities in the United States, where it has been a serious pest of corn, wheat, and other cereals for many years. This is the first record of any coniriderable numbe- of cotton stainers being found dead around their food plants in thf West Indies, and it would appear that the conditions are not often favourable for such an attack as this one. At tho same time it must be stated that the campaign which is now being carried out against the wild food plants of the stainers is resulting in more attention being paid to these insects in relation to sn
