Mr. Gitfard reported having this day received a cablegram 

 from Dr. Silvestri at Cape Town, to the etfect that he had ar- 

 rived there with parasites of the Mediterranean f rnitfly ; that 

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

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

 Mr. Giffard was of the opinion that he had obtained these para- 

 sites in South Xigeria, where he had been searching for the 

 Mediterranean fruitiiy and parasites. Dr. Silvestri had found 

 Ceratitis capifata at this place, but scarce. He had also found 

 a Chalcidid parasite, specimens of which had been sent to Hono- 

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

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

 had found a number of species of fruittiy 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. 



Mr. ^luir brought up the statement that an introduced in- 

 sect sometimes drives out a competing insect which has been 

 already present (probably native), and cited Pontia rapae as 

 an example. Pontia protodlce having become I'educed in the 

 United States after P. rapae had become introduced from Eu- 

 rope. Some discussion of the question followed.
