NOTES. 



Mr. Fullaway reported finding the small ant, Plagiolcpls 

 exigiia, spread all through ]\Iakiki and on the lower slope of 

 Tantalus. It was very abundant at the Government Nursery, 

 often getting into the ant-proof insectary. This ant was first 

 recorded by Mr. Ehrhorn in January, 1912. 



Mr. Pemberton said that he had observed the .<ame ant 

 abundant lately in Dr. Back's otfice on King street. 



Mr. Bridwell related that a process called ''sweating" takes 

 place in all Dipterous pupae which have come mider his obsci-- 

 vation in breeding fruitfly and ])ornfiy ])arasites. lie had 

 noticed, however, a watery liquid exuding from the anus of a 

 freshly formed puparium of a Sarcopliaga, and that the freshly 

 formed puparium of Volucclla ohem exudes a whitish li(piid 

 from the anus. From these ol)servations he inferred that the 

 "sweating" was of a similar nature, occurring only when ])ui»a- 

 ria were freshly formed. 



Mr. Fullaway, in discussing this, stated that at first it was 

 thought that this "sweating", or abundance <»f moisture that 

 occurred when they had puparia in a mass, was an acciunida- 

 tion condensed from the air. 



Mr. Bridwell called attention to the present abundance of 

 the introduced wasp, Trypoxylon bicolor. Other members cor- 

 roborated in this and Mr. Giifard related having hrst collected 

 it as earlv as 1905.
