insects exudes from the openings on the back of the abdomen in the 

 nymph stage and from the under side after the adult winged stage is 

 reached. Mr. Howard says, *'l would incline to think that injury 

 is caused by punctures and not by the secretion of these glands as their 

 contents are discharged only when disturbed by man or enemies. 

 They Itan no urine and excreta from digestive tract is hard." 

 There can be no question that one of the greatest pests of the lychee 

 is this insect and the Chinese combat it as best they can by climbing 

 the trees and scooping the adults and nymphs in by means of nets or 

 picking them by hand. Modern methods for fighting this enemy will 

 be watched by the Chinese with great interest. They will be ready 

 to adopt such methods as soon as shown they are more economical 

 than their present hand warfare.

Growers of tip-land lychee experience considerable trouble 

 with several species of Scarabeidat which they call Huauy cJi'uny 

 (Wong ch'uny $&). These appear in great swarms in the month 

 of April, just about the time the flower buds of the lychee open. In 

 South China hundreds of acres of rolling land are devoted to graves, 

 upon which the Chinese graze their cattle. This sod provides an 

 ideal home for the larvae of these insects and in the spring myriads 

 of adults emerge and attack the leaves and flower buds of many trees. 

 The chief remedial measure of the Chinese is to attack these insects 

 in the adult stage. They go out with torches and pick them from 

 the trees. At the Canton Christian College the people pick (hem 

 by hand, the agricultural department purchasing them by weight and 

 using them for chicken food. These insects are only troublesome 

 on the higher areas and are not a factor for consideration where trees 

 are grown under wet conditions at any considerable distance from 

 sod land. 



Mr. C. W. Howard reports the most common species found 

 about Canton in the order of their importance:
