an insect lacks food ia one .place he tries to emigrate to new 

 pastures. The damage caused by this plague this year in the 

 Province of Camagiiey may be estimated at more than 20 to 

 25,000 dollars, since no less than 40 to 50 caballerias of pasture 

 have been completely dried out by this insect, without hopes of 

 the grass growing again, or if it lives it is so impoverished that 

 it quickly goes to seed, and its place is taken by bad weeds and 

 stronger brush. 



The losses in sugar cane we have not been able to estimate 

 since the plague was not very extensive nor of long duration here^ 

 but in Trinidad (Briti^ West Indies) it causes considerable da- 

 mage, sucking the juices from the plant and causing the leaves 

 to turn yellow and dry up, although it is said that if the weather 

 changes and becomes drier so that the plague ceases, the sugar 

 sane will sucker again. 



METHODS OF CONTBOLLING THE PLAGUE. 



Owing to the special conditions in the pastures of the Pro- 

 vince of 'Camagiiey that have been almost all in timber and in 

 them still remain many trunks of trees, it, is difficult to 

 take sucih means as would be applicable on smooth lands, free 

 from obstacles and of much less extension. 



When there has been reached the extremity of having com- 

 pletely lost all of the parana, as in\this special case, there is no 

 longer hope of saving anything of the pasture, and every means 

 should be taken to destroy the eggs and nymphs and adults. In 

 this case there can be advised notlhing more than to set fire to the 

 pasture as soon as the weather is suitable, a fireguard being 

 formed just a little outside the limits of the plague, so as to 

 include all of the insects. 



When it is first observed that the grass is infested and that 

 the number of the insects, is already large, every means should 

 be tried for their destruction, which may be done in various ways. 

 For the purpose of destroying the adults one of t!he methods that 

 has been used with success in Trinidad consists in locating trap- 

 lights in the fields at certain distances from each other. These 

 trap-lights consist of a powerful light with a reflector located 

 above some container v^ith coal tar or kerosene, in such a way 

 that the insects that are attracted by the light fall into the cour 

 tainer. This apparatus may be more or less elaborated according 

 to the ingenuity of the one maJking it. 



Another means that would be more appropriate in this case 

 and that is more recommended for the treatment of large areas 

 consists in passing over all the field a wooden beam m the manner
