following, viz., Catochrysops cue jus, Anarsia ephippias, 

 Eucosma melanaula and Eublemma hemirhoda (Plate XX). 

 A. ephippias and E. melanaula commenced the attack by 

 rolling and damaging the tender top-leaves, and, when the 

 crop began to flower, all four appeared and damaged the 

 flowers. They continued their injurious activities when 

 the pods formed, all the four boring into the pods and 

 eating the see-ds. Eucosma melanaula was also observed to 

 cause similar damage to the flowers and pods of Phaseolus 

 aconitifolius and also to damage the tender top-leaves of an 

 experimental crop of Florida Beggar Weed. 



(30) Quite appreciable damage was done in August to 

 the new tender leaves of litchi by Acrocercops hierocosma, 

 whose larvae mined them, and by Argyroploce leucaspis, 

 whose caterpillars rolled and nibbled them. The latter 

 especially was very common. 



Grain Storage Experiments. The storage experi- 

 ments undertaken three years ago were concluded and an 

 account of them will be written up. The method of storage 

 under a layer of sand gave the best results, the grains and 

 pulses remaining perfectly safe and in good condition. 

 The straw granaries mentioned in last year's Report did 

 not give as good results as had been expected. 



-The status of Tribolium castaneum was definitely deter- 

 mined during the year. It is essentially a pest of ground 

 wheat (flour, atta and suji) and does great damage to these 

 products, especially during the Rains, by imparting to them 

 a characteristic nauseous smell and taste, which lowers 

 their value as food and consequently also the price of 

 infected material; in cases of bad infection, indeed, the 

 flour may be quite uneatable. In order to determine its 

 capacity for injury to sound wheat, i.e., whole grains 

 unaffected by Calandra oryza? or Rhizopertha dominica, 

 several thousand adults of Tribolium castaneum were con- 

 fined in an earthen vessel with a quantity of wheat which, 

 at the end of a year, was found to have been hardly 

 damaged, although breeding on a small scale had taken, 

 place, as was evident from a few cast larval skins. This
