Mr. Ehrhorn exhibited a female jMediterranean frnitfly, the 

 ovipositor of which had become stnck in a small Chrysophyllnm 

 frnit during oviposition and had died in this position, the jnice 

 of the frnit being very gnmmy. Dr. Back stated that he had 

 also observed this often in the same fruit. 



Prof. Illingworth reported that in some experiments in 

 spraying squashes with Sodium Arsenite they were not free 

 from the attack of the melon fly. 



Mr. Ehrhorn stated that he had observed Pseudococcus fila- 

 mentosus so prevalent on the orange trees in Judge Cooper's 

 orchard in Manoa Valley that practically every terminal bud 

 was badly dwarfed and curled thru the infestation of this mealy-

Mr. Swezey also exhibited specimens of an Ortalid fly, pos-
