less rainfall. In the extensive seed beds grown by the agricultural 
agents with the help of Red Cross funds for the rehabilitation of the 
coffee industry the pest, owing to systematic and thorough spraying, 
was of little importance.

The beetle ^ Di.abrotica - ramlnea Baly has been more abundant and 
injurioiis tiian previously, owing no doubt to the increase of plantings 
of string beans since the hurricane of September, 1323. Severe inf estations 
were reported from Caguas in the spring and summer of 1929. 
A bean leaf beetle, Corotoma denticornis Jab., was generally present 
in all bean plantings and doing some damage, especially where no spraying 
had been done. 
The bean lac ebug -a ( Cory t hue ha gossypii Fab. ) was injurious to 
several small plantings of lina beans during the summer of 1930 at Rio 
Piedras and at Palo Seco; the leaves turned whitish or brownish and some 
fell, greatly reducing pod formation. 
A leafhopper, I hipoasca sp. , was common and often very injurious to 
small patches of beans which were unsprayed. 
The bean pod borer ( l/Iaruca testulalis G-eyer) was not very common 
in lima or string beans during the spring and summer, probably owing to- 
£.3 fact that the host plant is scarce during these seasons. 
The bean leaf roller.. ( G-oniurus proteus L. ) was present in most 
plantings of beans that were examined.

The potato flea beetle ( jgpitrix cucuneris Harr. ) was very injurious, 
espjcfilly in seed-beds and in the field at Rio Piedras from March to 
May, 1930, but most of the damage in the field as usual was done from 
late September on. 
The melon aphid ( Aphis gossypii C-lov.) was more or less injurious 
to eggplant all over the Island throughout the year. 
The eggplant lac ebug ( Corythucha noracha Stal) 2ms 'oeen common and 
often very injurious where spraying has not been frequent and thorough. 
Climbing cutworms (IToctuidae) did considerable damage to the buds 
and to young eggplant on experimental plots at the Insular Experiment 
Station at Rio Piedr?s. 
A leaf tier ( P s ar a p e ru s i al i s Walh. ) has done considerable damage 
to eggplant both in the seed bed and in the field at Rio Piedras from 
September to January, but little trouble has been noticed since.
