larvae on hatching burrow their way to the centre of the fruit, where 

 pupation takes place in July. If the melon is not very large and the 

 pulp is soft enough, they bore their way out again and pupate about 

 I inch under the surface of the soil or under the remains of plants. 

 Pupation may also take place halfway between the centre and circum- 

 ference of the melon. Should the larvae not succeed in emerging 

 from the melon, the fruit does not deteriorate much in value, but once 

 an exit is made allowing the entrance of bacteria, it rots rapidly. 

 The thin-skinned early-ripening summer varieties suffer most, the 

 thick-skinned winter ones being least affected. There are two genera- 

 tions, one in July, the other in August. 



Nothing is so far known of the various stages. In 1917 as much 

 as 80 per cent, of the melons were injured by this fly, but in 19] 8 it was 

 not seen at all, probably owing to low temperature during the spring. 



The only remedial measure so far adopted is to protect the fruits 

 from oviposition by covering them with earth, but as this deteriorates 

 the quality of the fruit, it is not advocated. 



Cucumis citrullus (water melon) is also attacked by this fly, but to 

 a less extent.

Gynaikothrips uzeli, Zinun., was first observed in Cuba in 1887 and 

 is now common on many species of Ficus, especially F. retusa, 

 F. henjamina, and F. niiida.

The life-history and damage occasioned by Aleurocantkus woglumi, 

 Quaint., on citrus in Cuba are described [see this Review, Ser. A, vi, 

 p. 392]. A certain measure of control is exercised in the Island by 

 fungus diseases, the chief of which is perhaps the species infesting it 

 in Florida [see this Review, Ser. A, iii, p. 651], and another that appears 

 to be Aschersonia aleurodis.

The froghopper, MonecpJiora bicincta. Say, has increased to alarming 

 numbers in certain parts of Cuba [see this Revieiv, Ser. A, vi, p. 392],
