A NEW THRIPS DAMAGING ORCHIDS IN THE WEST INDIES. 61 



This species is chiefly recognisable by its yellow body colour, brown fore wings 

 and the relatively long antennae. 



The larvae and pupae are found with the adults on the upper surfaces of the 

 leaves, particularly near the mid rib and towards the base of the leaf. They cause 

 injury by piercing the surface, resulting in brownish spots or patches on the leaves. 

 In severe cases the plant may be entirely killed.
