 he would breed them there, then go on to Australia ; breed them 

 there, then finally proceed from there to Honolulu with them.

 lulu. In other parts of West Africa where he had been search- 

 ing, he had found Braconids parasitic on various fruitflies. He 

 had found a number of species of fruitfly of the genus Ceratitis 

 in West Africa, but no capitata until he had reached South 

 Nigeria. The new species that he discovered have been worked 

 up and published by Dr. Bezzi,

 rope. Some discussion of the (piestion followed.
